Overture

MCP ServerFree

Overture is an open-source, locally running web interface delivered as an MCP (Model Context Protocol) server that visually maps out the execution plan of any AI coding agent as an interactive flowchart/graph before the agent begins writing code.

mcp-based agent plan interception and blocking

Medium confidence

Intercepts AI coding agent execution at the planning phase by registering 11 MCP tools over stdio transport that agents must call sequentially (get_usage_instructions → submit_plan → get_approval → update_node_status → plan_completed/plan_failed). The server blocks agent progression at the get_approval call until user approval is granted, preventing code execution without review. Uses MCP stdio transport as the communication channel between agent and server, with the server maintaining plan state in memory and persisting to disk.

Solves for

I want to review what an AI agent plans to do before it starts writing codeI need to stop an agent from executing a flawed plan and provide correctionsI want to inject missing context (API keys, architectural preferences) before execution beginsI need to choose between alternative implementation approaches the agent suggests

Best for

developers using Claude Code, Cursor, Cline, or GitHub Copilot who want human-in-the-loop control

teams that require approval workflows before AI-generated code changes

solo developers building LLM agents who need visibility into agent decision-making

Requires

Node.js >=18.0.0

AI agent with MCP support (Claude Code, Cursor, Cline, GitHub Copilot 1.99+, or Sixth AI)

Agent configured with overture-mcp in its MCP server config (claude mcp add, ~/.cursor/mcp.json, VS Code settings, etc.)

Limitations

Blocks agent execution entirely until approval — no partial/conditional approval of plan subsets

Requires agent to implement the 11-tool MCP contract — incompatible with agents that don't support MCP

Plan state is in-memory; server restart loses current plan state (history persists but active plans don't)

What makes it unique

Uses MCP stdio transport to inject a blocking approval gate into the agent execution pipeline, with agent-specific prompt templates (via get_usage_instructions) that encode XML formatting rules and execution conventions per agent type. This is architecturally distinct from post-hoc code review tools because it intercepts at the planning phase before any code is written.

vs alternatives

Provides earlier intervention than code review tools (blocks at plan stage, not after code generation) and works with multiple agent types via a single MCP server, whereas agent-specific plugins require separate implementations per agent.

interactive flowchart visualization of execution plans

Medium confidence

Renders AI agent execution plans as interactive directed acyclic graphs (DAGs) in a browser-based UI, with nodes representing tasks and edges representing dependencies. The visualization is built as a pre-compiled React bundle served by Express on port 3031, connected to the MCP server via WebSocket on port 3030. Nodes display status (pending, in-progress, completed, failed) in real-time as the agent executes, with user interactions (approve, reject, edit) sent back to the server via WebSocket and relayed to the agent via MCP tool responses.

Solves for

I want to see a visual representation of what the agent plans to do before executionI need to understand task dependencies and execution order at a glanceI want to approve or reject the plan with a single clickI need to track which tasks have completed and which are in progress

Best for

developers who prefer visual planning over reading text-based execution logs

non-technical stakeholders reviewing agent plans before approval

teams using CI/CD pipelines where plan visualization aids debugging

Requires

Modern web browser (Chrome, Firefox, Safari, Edge)

Network connectivity to localhost:3031 (HTTP) and localhost:3030 (WebSocket)

MCP server running (npx overture-mcp)

Limitations

Visualization is read-only during execution — cannot edit individual nodes mid-execution

DAG rendering performance degrades with >100 nodes (no pagination or virtualization mentioned)

Browser must be open and connected via WebSocket — disconnection loses real-time updates

What makes it unique

Combines real-time WebSocket-driven status updates with a pre-built React UI bundle, allowing the browser to reflect agent execution progress without polling. The visualization is agent-agnostic (works with any agent that submits XML plans), and the DAG structure is extracted from the XML plan schema rather than inferred from logs.

vs alternatives

Provides live visualization of plan execution (not just static plan submission) and works across multiple agent types, whereas agent-specific UIs (e.g., Claude Code's built-in UI) are tightly coupled to a single agent.

agent-specific configuration management

Medium confidence

Manages agent-specific MCP server configuration for Claude Code, Cursor, Cline, GitHub Copilot, and Sixth AI, with each agent having a different configuration mechanism (claude mcp add, ~/.cursor/mcp.json, VS Code settings, .vscode/mcp.json, sixth-mcp-settings.json). The server provides documentation and examples for configuring each agent type, and the get_usage_instructions tool returns agent-specific prompt templates that encode the correct XML formatting for that agent.

Solves for

I want to configure Overture for my specific AI agentI need to understand how to set up MCP for my agent typeI want to ensure my agent is using the correct XML format for plans

Best for

developers setting up Overture for the first time with a specific agent

teams deploying Overture across multiple agent types

users migrating from one agent to another

Requires

Agent installed and configured with MCP support

Knowledge of agent-specific config file locations and formats

Limitations

Configuration is agent-specific — no unified config file

Documentation is external (README, docs) — no in-app configuration wizard

No validation that agent is correctly configured — errors only appear at runtime

What makes it unique

Provides agent-specific configuration guidance and prompt templates for each supported agent type (Claude Code, Cursor, Cline, GitHub Copilot, Sixth AI), rather than requiring users to manually configure MCP for each agent. The get_usage_instructions tool returns agent-specific templates that encode the correct XML formatting.

vs alternatives

Simplifies agent setup by providing pre-built configuration examples and prompt templates versus requiring users to manually configure MCP and write their own prompts.

plan submission and streaming with xml validation

Medium confidence

Accepts XML-encoded execution plans from agents via the submit_plan MCP tool, validates the XML structure against the expected schema, parses it into a DAG, and streams the plan to the browser UI via WebSocket. The server stores the plan in memory (PlanStore) and persists it to history.json. Validation ensures the plan conforms to the expected structure before visualization and execution tracking begin.

Solves for

I want to submit a plan from my agent to OvertureI need to validate that my plan structure is correctI want to visualize my plan immediately after submission

Best for

agents that need to submit structured plans to Overture

systems that require plan validation before execution

teams that need to audit plan submissions

Requires

Valid XML plan structure matching the expected schema

Agent must call submit_plan with XML-encoded plan

Limitations

XML-only — no support for JSON or other formats

Validation is schema-based — no semantic validation (e.g., circular dependency detection)

Plan size is unbounded — very large plans may cause memory issues

What makes it unique

Combines XML parsing, schema validation, DAG extraction, and WebSocket streaming into a single submit_plan tool, enabling agents to submit plans and have them visualized in the browser UI in a single operation. The validation ensures plan structure is correct before visualization.

vs alternatives

Provides end-to-end plan submission with validation and visualization versus agents that submit plans without validation or visualization.

agent-specific prompt template generation

Medium confidence

Generates customized XML formatting instructions and execution conventions for each supported agent type (Claude Code, Cursor, Cline, GitHub Copilot, Sixth AI) via the get_usage_instructions MCP tool. The server maintains agent-specific templates that encode the correct XML schema, node/edge structure, and status update conventions for each agent's implementation. Templates are returned as text and injected into the agent's system prompt or context, ensuring the agent generates plans in the correct format.

Solves for

I want the agent to generate plans in the correct XML format for my specific agent typeI need agent-specific execution conventions (e.g., how Cursor handles async tasks differently than Claude Code)I want to ensure the agent understands the plan submission and approval workflow

Best for

developers integrating Overture with a specific agent (Claude Code, Cursor, Cline, GitHub Copilot, Sixth AI)

teams deploying Overture across multiple agent types and needing consistent plan formats

Requires

Agent must call get_usage_instructions before submitting a plan

Agent must support MCP tool calling

Limitations

Templates are static and hardcoded per agent — no dynamic customization per user or project

Agent must respect the template instructions — no validation that agent actually follows the format

New agent types require code changes to add new templates (no plugin system for custom agents)

What makes it unique

Maintains separate prompt templates per agent type (Claude Code, Cursor, Cline, GitHub Copilot, Sixth AI) that encode agent-specific XML formatting rules and execution conventions, rather than using a single generic template. This allows the server to work with agents that have different MCP implementations or XML parsing quirks.

vs alternatives

Eliminates the need for users to manually write agent-specific prompts by providing pre-built templates, whereas generic MCP servers require users to handle agent-specific formatting themselves.

xml plan parsing and dag extraction

Medium confidence

Parses XML-encoded execution plans submitted by agents into an in-memory graph structure (nodes and edges) that represents the execution DAG. The parser extracts task descriptions, dependencies, and metadata from the XML, validates the structure against the expected schema, and builds a directed acyclic graph for visualization and execution tracking. The parsed plan is stored in memory (PlanStore) and persisted to disk as JSON for history/audit purposes.

Solves for

I need to extract structured task information from an agent's XML planI want to validate that the plan structure is correct before executionI need to track plan history and audit what agents planned to do

Best for

developers building plan visualization systems

teams that need to audit or replay agent execution plans

systems that need to validate plan structure before execution

Requires

Valid XML plan structure matching the expected schema

Node.js XML parsing library (likely built-in or via npm dependency)

Limitations

Parser is XML-specific — no support for JSON or other plan formats

No schema validation library mentioned — validation logic is likely custom and may miss edge cases

Circular dependency detection is not mentioned — malformed plans with cycles may not be caught

What makes it unique

Parses agent-submitted XML plans into a DAG structure that is both visualizable (for the browser UI) and executable (for tracking node status updates). The parser is agent-agnostic and works with any agent that submits XML in the expected schema, enabling multi-agent support without agent-specific parsing logic.

vs alternatives

Provides structured plan extraction (not just logging raw XML) and enables visualization and execution tracking, whereas agents that don't use Overture have no mechanism to extract or visualize their internal plans.

real-time plan execution status tracking

Medium confidence

Tracks the execution state of each node in the plan as the agent progresses through tasks, updating node status (pending → in-progress → completed/failed) via the update_node_status MCP tool. The server maintains the current state in memory (PlanStore) and broadcasts status updates to the browser UI via WebSocket, allowing real-time visualization of execution progress. Supports resuming failed nodes and completing plans with success or failure status.

Solves for

I want to see which tasks have completed and which are currently runningI need to know if a task failed and whyI want to resume a failed task without restarting the entire planI need to track execution time and performance per task

Best for

developers monitoring long-running agent tasks

teams that need to debug failed agent executions

systems that require fault tolerance and task resumption

Requires

Agent must call update_node_status for each node as it executes

WebSocket connection from browser to server for real-time updates

Limitations

Status tracking is in-memory only — server restart loses current execution state

No built-in retry logic — resume requires explicit agent call to update_node_status

No execution time tracking mentioned — cannot analyze task performance

What makes it unique

Maintains a real-time execution state machine for each plan node, with WebSocket-driven updates to the browser UI and support for resuming failed nodes without restarting the entire plan. This is distinct from logging-based execution tracking because it provides structured state transitions and enables interactive recovery.

vs alternatives

Provides real-time execution visibility with interactive recovery (resume failed nodes) versus traditional logging systems that only record execution history after the fact.

plan history persistence and retrieval

Medium confidence

Persists all submitted plans to disk as JSON in ~/.overture/history.json, maintaining a complete audit trail of what agents planned to do. The HTTP server (Express on port 3031) exposes endpoints to retrieve plan history, allowing users to review past plans, compare execution outcomes, and audit agent behavior over time. History is loaded on server startup and appended to as new plans are submitted.

Solves for

I want to review what an agent planned to do in a previous sessionI need to audit all plans submitted by agents for compliance or debuggingI want to compare how different agents approached the same taskI need to restore a previous plan and re-execute it

Best for

teams that require audit trails for compliance or governance

developers debugging agent behavior across multiple sessions

systems that need to replay or compare agent plans

Requires

Write access to ~/.overture/ directory

Disk space for history file (grows with each plan submission)

Limitations

History file is a single JSON file — no indexing or search (linear scan required)

No automatic cleanup — history file grows unbounded and may become very large

No encryption or access control — history file contains all plan details in plaintext

What makes it unique

Provides automatic persistence of all plans to a local JSON file without requiring external databases, enabling offline access and easy backup. The history is agent-agnostic and works with any agent that submits plans via the MCP interface.

vs alternatives

Offers local-first persistence (no cloud dependency) and complete audit trails versus agents that don't log plans at all, though it lacks the scalability and querying capabilities of a proper database.

multi-agent integration via mcp tool contract

Medium confidence

Provides a standardized MCP tool contract (11 tools: get_usage_instructions, submit_plan, get_approval, update_node_status, plan_completed, plan_failed, etc.) that any AI agent can implement to integrate with Overture. The server registers these tools over the MCP stdio transport, and agents call them in a specific sequence to submit plans, request approval, and track execution. This enables Overture to work with Claude Code, Cursor, Cline, GitHub Copilot, and Sixth AI without agent-specific code changes.

Solves for

I want to use Overture with my preferred AI agent (Claude Code, Cursor, Cline, etc.)I need a standardized interface for agents to submit plans and request approvalI want to add support for a new agent type without rewriting Overture

Best for

developers using multiple AI agents who want a unified plan review interface

teams building custom AI agents that need to integrate with Overture

MCP ecosystem participants who want to standardize plan submission workflows

Requires

AI agent with MCP support (Claude Code, Cursor, Cline, GitHub Copilot 1.99+, Sixth AI)

Agent configured to connect to overture-mcp via MCP stdio transport

Limitations

Requires agent to implement the full 11-tool contract — partial implementations won't work

MCP stdio transport is synchronous — agents block on get_approval until user responds

No versioning of the tool contract — breaking changes require all agents to update

What makes it unique

Defines a 11-tool MCP contract that abstracts away agent-specific differences, allowing a single server to work with multiple agent types (Claude Code, Cursor, Cline, GitHub Copilot, Sixth AI) without agent-specific code. This is architecturally distinct from agent-specific plugins because it uses a standard protocol (MCP) rather than custom integrations.

vs alternatives

Enables multi-agent support via a single standardized interface versus agent-specific plugins that require separate implementations and maintenance for each agent type.

websocket-driven real-time ui updates

Medium confidence

Establishes a WebSocket connection (port 3030) between the browser UI and the MCP server, enabling real-time bidirectional communication. The server broadcasts plan status updates (node completed, failed, etc.) to the browser, and the browser sends user interactions (approve, reject, edit) back to the server. This eliminates polling and provides instant visual feedback as the agent executes tasks.

Solves for

I want to see plan status updates in real-time without refreshing the pageI need to approve or reject a plan and have the agent respond immediatelyI want to edit a plan and have changes reflected instantly

Best for

developers monitoring long-running agent tasks

teams that need instant feedback on plan approvals

systems with low-latency requirements for user interactions

Requires

WebSocket support in browser (all modern browsers)

Network connectivity to localhost:3030

MCP server running with WebSocket service enabled

Limitations

WebSocket connection is required — no fallback to polling or HTTP long-polling

Disconnection loses real-time updates — no reconnection logic mentioned

No message ordering guarantees — out-of-order updates may cause inconsistent UI state

What makes it unique

Uses WebSocket for bidirectional real-time communication between browser and server, enabling instant status updates and user interactions without polling. The WebSocket protocol is defined in the DeepWiki documentation and supports a specific message format for plan events.

vs alternatives

Provides lower latency and better user experience than polling-based approaches, and enables interactive workflows (approve/reject with immediate agent response) that aren't possible with unidirectional HTTP.

express http server for ui bundle serving and history endpoints

Medium confidence

Runs an Express HTTP server on port 3031 that serves the pre-built React UI bundle (static HTML/CSS/JavaScript) and exposes REST endpoints for retrieving plan history. The server loads the UI bundle from the ui-dist directory and serves it as a single-page application. History endpoints allow clients to fetch all plans or specific plan details in JSON format.

Solves for

I want to open the Overture UI in my browser to review and approve plansI need to retrieve plan history via HTTP APII want to integrate Overture's history data into my own dashboard or reporting system

Best for

developers who prefer web-based UIs over CLI tools

teams that need to integrate plan history into existing dashboards

systems that require HTTP API access to plan data

Requires

Network connectivity to localhost:3031

Modern web browser for SPA support

MCP server running with HTTP service enabled

Limitations

Single-page application — no server-side rendering or SEO

No authentication or authorization — anyone with network access can view plans

No rate limiting — API endpoints are unprotected against abuse

What makes it unique

Combines a static SPA server (for the browser UI) with REST endpoints for history retrieval, allowing both interactive use (via browser) and programmatic access (via HTTP API). The UI bundle is pre-built and served as static files, eliminating the need for server-side rendering.

vs alternatives

Provides a lightweight HTTP server (Express) that serves both UI and API endpoints, versus separate servers for UI and API which would require more infrastructure.

plan approval workflow with blocking semantics

Medium confidence

Implements a blocking approval workflow where agents call get_approval and wait for user response before proceeding. The server holds the MCP tool call open until the user approves or rejects the plan via the browser UI, at which point the tool response is sent back to the agent. This creates a synchronous approval gate that prevents code execution until human review is complete.

Solves for

I want to review a plan before the agent starts executing itI need to reject a plan and have the agent stop immediatelyI want to approve a plan and have the agent continue execution

Best for

teams that require human approval before AI-generated code changes

developers who want to catch agent mistakes before code is written

systems with compliance requirements for code review

Requires

User must be actively monitoring the browser UI

WebSocket connection from browser to server must be active

Agent must call get_approval and wait for response

Limitations

Blocking semantics mean agents cannot proceed until approval — no timeout or auto-approval

No partial approval — must approve or reject the entire plan

No approval history or audit trail of who approved what (only plan history)

What makes it unique

Uses synchronous MCP tool semantics (blocking on get_approval) to create a hard gate in the agent execution pipeline, preventing any code execution until user approval. This is architecturally simpler than asynchronous approval systems but requires the user to be actively monitoring.

vs alternatives

Provides guaranteed human review before execution (blocking semantics) versus post-hoc code review tools that can only catch mistakes after code is written.

Requires agent to implement the full 11-tool contract — partial implementations won't work

MCP stdio transport is synchronous — agents block on get_approval until user responds

No versioning of the tool contract — breaking changes require all agents to update

What makes it unique

vs alternatives

Enables multi-agent support via a single standardized interface versus agent-specific plugins that require separate implementations and maintenance for each agent type.

websocket-driven real-time ui updates

Medium confidence

Solves for

Best for

developers monitoring long-running agent tasks

teams that need instant feedback on plan approvals

systems with low-latency requirements for user interactions

Requires

WebSocket support in browser (all modern browsers)

Network connectivity to localhost:3030

MCP server running with WebSocket service enabled

Limitations

WebSocket connection is required — no fallback to polling or HTTP long-polling

Disconnection loses real-time updates — no reconnection logic mentioned

No message ordering guarantees — out-of-order updates may cause inconsistent UI state

What makes it unique

vs alternatives

express http server for ui bundle serving and history endpoints

Medium confidence

Solves for

Best for

developers who prefer web-based UIs over CLI tools

teams that need to integrate plan history into existing dashboards

systems that require HTTP API access to plan data

Requires

Network connectivity to localhost:3031

Modern web browser for SPA support

MCP server running with HTTP service enabled

Limitations

Single-page application — no server-side rendering or SEO

No authentication or authorization — anyone with network access can view plans

No rate limiting — API endpoints are unprotected against abuse

What makes it unique

vs alternatives

Provides a lightweight HTTP server (Express) that serves both UI and API endpoints, versus separate servers for UI and API which would require more infrastructure.

plan approval workflow with blocking semantics

Medium confidence

Solves for

I want to review a plan before the agent starts executing itI need to reject a plan and have the agent stop immediatelyI want to approve a plan and have the agent continue execution

Best for

teams that require human approval before AI-generated code changes

developers who want to catch agent mistakes before code is written

systems with compliance requirements for code review

Requires

User must be actively monitoring the browser UI

WebSocket connection from browser to server must be active

Agent must call get_approval and wait for response

Limitations

Blocking semantics mean agents cannot proceed until approval — no timeout or auto-approval

No partial approval — must approve or reject the entire plan

No approval history or audit trail of who approved what (only plan history)

What makes it unique

vs alternatives

Provides guaranteed human review before execution (blocking semantics) versus post-hoc code review tools that can only catch mistakes after code is written.

Capabilities are decomposed by AI analysis. Each maps to specific user intents and improves with match feedback.
