Enables MCP clients to execute multiple tools in sequence where output from one tool automatically becomes input context for the next tool in the chain. Implements a state machine pattern that tracks execution flow, maintains intermediate results, and handles error propagation across chain steps. The server parses tool invocation requests, validates schemas at each step, and ensures context is properly serialized between tool boundaries.
Unique: Implements tool chaining as a first-class MCP server capability rather than client-side orchestration, allowing MCP clients (like Claude) to invoke chains directly via standard tool-calling interfaces without custom orchestration logic
vs alternatives: Simpler than building orchestration in client code because the server handles state management and context propagation; more transparent than black-box agent frameworks because chain execution is explicit and debuggable
Validates incoming tool invocation requests against registered tool schemas and transforms parameters between chain steps using schema-aware mapping. The server maintains a registry of tool definitions with JSON Schema validation, performs type coercion where safe, and rejects malformed requests with detailed error messages indicating which schema constraint was violated. Supports parameter renaming and structural transformation between tool boundaries.
Unique: Performs schema validation at the MCP server layer rather than delegating to individual tools, enabling centralized validation policy enforcement and cross-tool parameter transformation without modifying tool implementations
vs alternatives: More reliable than client-side validation because validation happens before tool execution; more flexible than tool-embedded validation because transformation rules are defined in the chain configuration, not hardcoded in tools
Manages execution context and intermediate state across tool invocations within a single MCP session, storing results from each tool step and making them available to subsequent steps. The server maintains an in-memory context store keyed by execution session ID, serializes intermediate results, and provides context retrieval mechanisms for tools that need access to prior outputs. Supports context scoping (global vs. chain-local) and automatic cleanup of stale context.
Unique: Implements context management as an MCP server capability, allowing clients to access intermediate results through standard MCP tool calls rather than requiring custom state management logic in client code
vs alternatives: Simpler than external state stores (Redis, databases) for single-session workflows because context is co-located with the MCP server; more transparent than agent frameworks because context is explicitly queryable
Detects tool execution failures, captures error context, and provides configurable recovery strategies (fail-fast, retry with backoff, skip-and-continue, fallback-tool). The server implements error classification (schema validation errors vs. tool execution errors vs. timeout errors), logs detailed error traces with execution context, and allows chains to define per-step error handlers. Supports conditional error recovery based on error type and retry count.
Unique: Implements error handling at the MCP server layer with configurable per-step recovery strategies, allowing clients to define resilience policies declaratively in chain configuration rather than implementing error handling in tool code
vs alternatives: More granular than simple try-catch because it supports per-step error handlers and recovery strategies; more observable than tool-embedded error handling because all errors flow through a centralized logging system
Maintains a registry of available tools with metadata (name, description, schema, version) and exposes tool discovery mechanisms to MCP clients. The server implements tool registration endpoints, supports tool versioning, and provides introspection APIs that allow clients to query available tools, their schemas, and capabilities. Tools can be registered at server startup or dynamically added at runtime through registration endpoints.
Unique: Implements tool registry as a first-class MCP server feature with introspection APIs, allowing clients to dynamically discover and adapt to available tools without hardcoding tool names or schemas
vs alternatives: More discoverable than hardcoded tool lists because clients can query available tools at runtime; more maintainable than tool documentation in separate files because schemas are the source of truth
Records detailed execution traces for each tool chain invocation, including tool names, parameters, results, timing, and error information. The server implements structured logging with execution IDs, captures intermediate state at each step, and provides trace retrieval APIs that allow clients to inspect execution history. Traces include timing information for performance analysis and can be exported in standard formats (JSON, structured logs).
Unique: Implements automatic execution tracing at the MCP server layer, capturing all tool invocations and results without requiring instrumentation in individual tools or client code
vs alternatives: More complete than tool-level logging because it captures end-to-end chain execution; more accessible than external APM tools because traces are queryable directly through MCP APIs
Enables execution of independent tools in parallel within a single chain, with automatic dependency resolution to ensure tools execute in the correct order. The server analyzes tool parameter dependencies, identifies tools that can run concurrently, and executes them in parallel using async/await patterns. Supports explicit dependency declarations and automatic dependency inference from parameter references.
Unique: Implements automatic dependency analysis and parallel execution at the MCP server layer, allowing clients to define chains sequentially while the server optimizes execution order without client-side orchestration logic
vs alternatives: More efficient than sequential execution for I/O-bound chains; more transparent than hidden parallelization because dependency resolution is explicit and debuggable
Supports conditional execution paths within tool chains based on tool outputs, allowing chains to branch based on results and route to different tools dynamically. The server evaluates conditions (equality, comparison, regex matching) against tool outputs, selects the appropriate next step, and continues execution on the selected branch. Supports nested conditions and fallback paths when no condition matches.
Unique: Implements conditional branching as a first-class chain construct, allowing clients to define decision logic declaratively in chain configuration rather than implementing branching in tool code or client orchestration
vs alternatives: More readable than nested if-else in code because conditions are declarative; more flexible than hardcoded branching because routing decisions are based on runtime tool outputs
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
Invokes Supabase Edge Functions (serverless TypeScript/JavaScript functions) through MCP tools, passing parameters and receiving results with optional streaming support. Uses Supabase's edge function HTTP API to trigger functions with automatic authentication headers and response parsing, enabling agents to execute custom business logic without embedding it in the agent itself.
Supabase scores higher at 42/100 vs chaining-mcp-server at 25/100. chaining-mcp-server leads on ecosystem, while Supabase is stronger on quality.

Subscribes to real-time changes on Supabase tables through MCP's event streaming interface, using Supabase's PostgreSQL LISTEN/NOTIFY mechanism to push INSERT, UPDATE, and DELETE events to agents. Maintains persistent WebSocket connections and filters events by table and row-level policies, enabling agents to react to database changes without polling.
Unique: Bridges Supabase's PostgreSQL LISTEN/NOTIFY real-time system with MCP's tool interface, enabling agents to subscribe to database changes without managing WebSocket connections or event serialization
vs alternatives: More efficient than polling-based approaches because it uses Supabase's native real-time infrastructure rather than repeated database queries
Manages files in Supabase Storage buckets through MCP tools, supporting upload, download, list, and delete operations with automatic authentication and path-based access control. Uses Supabase's S3-compatible storage API with built-in support for public/private buckets and signed URLs for temporary access, enabling agents to handle file I/O without managing cloud storage credentials.
Unique: Exposes Supabase Storage's S3-compatible API as MCP tools with automatic authentication and signed URL generation, eliminating the need for agents to manage cloud storage credentials or generate temporary access tokens
vs alternatives: More integrated than generic S3 MCP tools because it leverages Supabase's built-in bucket policies and authentication rather than requiring separate AWS credentials
Performs semantic similarity searches on vector embeddings stored in Supabase PostgreSQL using pgvector extension, translating natural language queries into embedding vectors and executing cosine/L2 distance searches. Integrates with embedding providers (OpenAI, Cohere) or uses pre-computed embeddings, enabling agents to retrieve semantically similar documents or records without full-text search limitations.
Unique: Integrates pgvector directly into MCP tools with automatic embedding generation and distance calculation, enabling agents to perform semantic search without managing separate vector database infrastructure
vs alternatives: More efficient than external vector databases (Pinecone, Weaviate) for Supabase users because it colocates embeddings with relational data, reducing network latency and simplifying data synchronization
Exposes Supabase database schema information through MCP tools, allowing agents to discover table structures, column types, constraints, and relationships without manual schema documentation. Queries PostgreSQL information_schema and Supabase metadata tables to dynamically generate schema descriptions, enabling agents to construct valid queries and understand data relationships.
Unique: Queries Supabase's PostgreSQL information_schema directly through MCP tools, enabling agents to dynamically discover and adapt to database schemas without pre-configured schema definitions
vs alternatives: More flexible than static schema definitions because it reflects live database state, including recent migrations or schema changes
Enforces Supabase Row-Level Security policies within agent queries, ensuring that agents can only access rows permitted by RLS rules defined in the database. Evaluates policies based on authenticated user context (JWT claims, user ID) and applies WHERE clause filters automatically, preventing unauthorized data access at the database layer rather than application layer.
Unique: Delegates authorization enforcement to PostgreSQL RLS policies rather than implementing authorization in agent code, ensuring that data access rules are centralized and cannot be bypassed by agent logic
vs alternatives: More secure than application-level authorization because RLS is enforced at the database layer, preventing accidental data leaks even if agent code has bugs
