Implements a structured thinking tool that allows LLM clients to decompose complex problems into sequential reasoning steps with explicit branching, revision, and hypothesis tracking. The server exposes a single MCP tool that clients invoke to create hierarchical thought structures where each step can spawn multiple branches representing alternative reasoning paths, enabling non-linear exploration of solution spaces while maintaining full audit trails of the reasoning process.
Unique: Provides native MCP tool interface for structured branching reasoning with explicit hypothesis tracking and revision support, implemented as a reference server demonstrating MCP's tool capability primitive. Unlike generic prompt-based chain-of-thought, this exposes reasoning structure as first-class data that clients can inspect, manipulate, and persist independently.
vs alternatives: Offers protocol-level reasoning structure (via MCP tools) rather than relying on LLM output parsing, enabling deterministic branch tracking and client-side reasoning tree manipulation that generic prompt engineering cannot achieve.
Implements the MCP tool capability primitive by registering a structured tool schema that defines the reasoning interface (step creation, branching, revision operations) and handling tool invocation requests from MCP clients via JSON-RPC protocol. The server uses TypeScript SDK abstractions to define tool parameters (problem statement, step content, branch metadata) with JSON schema validation, then routes incoming tool calls to internal reasoning handlers that construct and return thought tree structures.
Unique: Demonstrates MCP tool capability as a reference implementation using TypeScript SDK, showing proper schema definition, parameter validation, and JSON-RPC request/response handling patterns. Serves as educational example for developers building their own MCP servers rather than a production tool framework.
vs alternatives: Official reference implementation from MCP steering group provides authoritative patterns for tool registration and invocation; more reliable for learning than community examples, though intentionally simplified for clarity over feature completeness.
Manages an in-memory hierarchical data structure representing reasoning steps as nodes with parent-child relationships, supporting operations like step creation, branching (creating sibling alternatives), revision (updating step content), and hypothesis labeling. The server maintains tree state during a session, allowing clients to reference previous steps by ID when creating new branches, and provides mechanisms to traverse the tree structure to retrieve reasoning history and branch relationships.
Unique: Implements hierarchical reasoning state as a first-class MCP capability, allowing clients to explicitly construct and navigate branching thought trees rather than parsing LLM text output. Uses parent-child reference semantics to support arbitrary branching depth and revision tracking without requiring external graph databases.
vs alternatives: Provides structured reasoning state management that generic prompt-based chain-of-thought cannot offer; enables deterministic branch tracking and client-side tree manipulation, though at the cost of requiring explicit client integration rather than working with any LLM via prompting alone.
Tracks modifications to reasoning steps and maintains metadata about hypothesis alternatives, allowing clients to record when a step is revised, why it was changed, and which hypotheses were explored or abandoned. The server stores revision history and hypothesis labels alongside step content, enabling clients to query the reasoning trajectory and understand decision points where the LLM chose one path over alternatives.
Unique: Provides explicit revision and hypothesis tracking as part of the reasoning tool interface, allowing clients to annotate why steps were changed and which alternatives were considered. Unlike generic reasoning logs, this captures structured metadata about decision points and abandoned paths.
vs alternatives: Enables systematic analysis of reasoning alternatives and revision decisions that text-based chain-of-thought logs cannot support; requires explicit client integration but provides richer interpretability data for reasoning analysis.
Implements the MCP server lifecycle including initialization, client connection handling, and graceful shutdown, using the TypeScript SDK's server abstractions. The server registers itself with the MCP protocol, advertises its capabilities (tools, resources, prompts) to connecting clients, and maintains session state for each connected client. Handles transport-level concerns like JSON-RPC message routing and error propagation through the MCP protocol layer.
Unique: Demonstrates MCP server lifecycle patterns using official TypeScript SDK, showing proper initialization, capability advertisement, and client session handling. Serves as reference for developers building their own MCP servers with correct protocol compliance.
vs alternatives: Official reference implementation ensures protocol compliance and best practices; more reliable than community examples for understanding correct MCP server patterns, though intentionally simplified for educational clarity.
Serializes hierarchical thought trees and reasoning metadata into JSON structures that MCP clients can consume, parse, and integrate into their own reasoning workflows. The server formats tool responses as structured JSON containing step IDs, branch relationships, content, and metadata, enabling clients to reconstruct the reasoning tree, visualize it, or feed it back into subsequent reasoning iterations. Supports round-trip serialization where clients can submit previous reasoning context to continue or refine reasoning.
Unique: Provides structured JSON serialization of reasoning trees that enables client-side tree visualization, manipulation, and round-trip context passing. Unlike text-based reasoning output, this maintains tree structure and relationships in machine-readable format.
vs alternatives: Enables rich client-side reasoning UI and context management that plain text chain-of-thought output cannot support; requires explicit client integration but provides better composability with downstream reasoning or visualization systems.
Serves as an official reference implementation for MCP server developers, demonstrating TypeScript SDK usage patterns, proper tool registration, error handling, and protocol compliance. The codebase is intentionally simplified and well-documented to serve as a learning resource for developers building their own MCP servers, rather than a feature-complete production system. Includes examples of how to structure tool handlers, manage server state, and respond to client requests according to MCP specifications.
Unique: Official reference implementation maintained by MCP steering group, providing authoritative patterns for tool registration, error handling, and protocol compliance. Intentionally simplified for educational clarity rather than feature completeness, making it ideal for learning but requiring enhancement for production use.
vs alternatives: Official status and steering group maintenance ensure accuracy and alignment with MCP specifications; more reliable for learning than community examples, though community servers may demonstrate more advanced features or production patterns.
Executes SQL queries against Supabase PostgreSQL instances through the Model Context Protocol, translating natural language or structured query requests into parameterized SQL statements. Uses MCP's tool-calling interface to expose database operations as callable functions with schema validation, enabling LLM agents to perform CRUD operations, joins, and aggregations with automatic connection pooling and credential management through Supabase client SDK.
Unique: Exposes Supabase PostgreSQL as MCP tools with automatic credential injection from Supabase client SDK, eliminating manual connection string management and enabling seamless LLM-to-database queries within Claude or compatible agents
vs alternatives: Tighter integration than generic SQL MCP servers because it leverages Supabase's built-in authentication and connection pooling rather than requiring separate database credential configuration
Exposes Supabase Auth session state and user metadata through MCP tools, allowing agents to inspect current authentication context, retrieve user profiles, and trigger auth-related operations. Integrates with Supabase's JWT-based auth system to validate sessions and access user claims without re-authenticating, using the Supabase client's built-in session management.
Unique: Integrates Supabase's JWT-based auth system directly into MCP tool interface, allowing agents to inspect and act on auth state without managing separate credential stores or re-authentication flows
vs alternatives: More seamless than generic auth MCP servers because it leverages Supabase's built-in session management and avoids redundant credential passing between agent and auth system
