Intercepts and cryptographically attests MCP (Model Context Protocol) tool invocations by wrapping the tool-calling interface, capturing execution metadata (tool name, arguments, timestamp, caller identity), and generating verifiable attestation proofs that can be validated downstream. Uses a middleware pattern to inject attestation logic into the MCP tool registry without modifying underlying tool implementations.
Unique: Provides drop-in attestation specifically for MCP tool calls via middleware wrapping, enabling cryptographic proof of tool invocation without requiring changes to tool implementations or MCP server code — focuses on the MCP protocol layer rather than generic function call logging
vs alternatives: Lighter-weight than building custom audit logging on top of MCP servers because it integrates at the protocol level; more specialized than generic observability tools because it provides cryptographic attestation rather than just metrics/tracing
Wraps the MCP tool registry (the central registry where tools are registered and discovered) to transparently inject attestation logic into tool definitions and execution paths. When a tool is registered or invoked through the wrapped registry, the wrapper automatically captures metadata, generates attestation proofs, and returns wrapped results with attestation attached, without requiring modifications to tool implementations or caller code.
Unique: Operates at the MCP registry abstraction level rather than individual tool level, allowing single-point injection of attestation across all tools via a wrapper pattern — enables uniform attestation policy without tool-by-tool configuration
vs alternatives: More maintainable than per-tool attestation wrappers because changes to attestation logic apply globally; more transparent than manual logging because it's injected at the registry boundary rather than scattered through tool code
Generates cryptographic proofs (signatures, tokens, or hashes) that bind tool invocation metadata (tool name, arguments, timestamp, caller identity, execution result) into a verifiable artifact. The proof generation likely uses HMAC, digital signatures, or similar schemes to create tamper-evident records that can be validated by external systems without access to the original tool execution context.
Unique: Generates cryptographic proofs specifically bound to MCP tool invocation context (tool name, args, caller, timestamp) rather than generic function call signatures — enables verification of tool calls as discrete events rather than just code execution
vs alternatives: More robust than simple logging because proofs are tamper-evident; more lightweight than full blockchain solutions because it uses standard cryptography rather than distributed consensus
Automatically captures structured metadata about each tool invocation (tool name, arguments, caller identity, timestamp, execution duration, result status) and serializes it into a canonical format suitable for attestation and audit logging. Uses introspection of the MCP tool call context to extract metadata without requiring explicit instrumentation of tool code.
Unique: Captures metadata at the MCP protocol boundary, extracting tool name, arguments, caller, and timing information automatically without requiring tool-level instrumentation — enables uniform metadata collection across heterogeneous tools
vs alternatives: More complete than manual logging because it captures all MCP context automatically; more standardized than ad-hoc logging because metadata is serialized in a canonical format
Provides mechanisms to validate and verify cryptographic attestation proofs generated by tool invocations, checking that proofs are well-formed, signatures are valid, and metadata has not been tampered with. Verification logic likely uses the same cryptographic keys/algorithms used for proof generation to reconstruct and validate the proof against captured metadata.
Unique: Provides verification specifically for MCP tool call attestations, validating that proofs correspond to actual tool invocations with claimed metadata — enables third-party validation of tool calls without re-execution
vs alternatives: More focused than generic cryptographic verification libraries because it understands MCP tool call context; more practical than blockchain-based verification because it uses standard cryptography without distributed consensus overhead
Captures and tracks the identity of the agent, user, or system that initiated a tool call, associating this caller context with each attestation. Integrates with MCP request context to extract caller information and binds it into the attestation proof, enabling traceability of which agent/user triggered which tool invocation.
Unique: Integrates caller identity tracking directly into MCP tool call attestation, binding agent/user identity to each proof — enables end-to-end traceability from user action to tool invocation to result
vs alternatives: More integrated than separate identity logging because caller context is bound into cryptographic proofs; more practical than centralized identity services because it captures identity at the point of tool invocation
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 @treeship/mcp at 22/100. @treeship/mcp leads on ecosystem, while Supabase is stronger on quality.

Unique: Exposes Supabase Edge Functions as MCP tools with automatic authentication and response parsing, allowing agents to invoke custom serverless logic without managing HTTP clients or credential injection
vs alternatives: More integrated than generic HTTP MCP tools because it handles Supabase-specific authentication, error handling, and response formatting automatically
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
