Provides a Node.js runtime environment for spinning up Model Context Protocol servers using the official MCP SDK. Handles server instantiation, connection negotiation, and graceful shutdown through a standardized initialization pattern that abstracts away low-level MCP protocol details. The runtime manages the server's lifecycle from startup through message routing to connected clients.
Unique: Built on the official MCP SDK from Anthropic, ensuring protocol compliance and forward compatibility; abstracts server lifecycle management through a Pikku-specific wrapper that simplifies common initialization patterns without forking the upstream SDK
vs alternatives: More lightweight than building MCP servers from scratch with raw socket handling, while maintaining direct access to the official SDK's latest protocol features and bug fixes
Enables developers to define tools (callable functions exposed to MCP clients) using JSON Schema for input validation and type safety. The runtime validates tool definitions against the MCP specification and registers them in a central tool registry that clients can discover via the MCP tools/list endpoint. Supports complex nested schemas, optional parameters, and description metadata for client-side UI rendering.
Unique: Leverages the official MCP SDK's tool registration system with Pikku's simplified wrapper API; validates schemas at registration time rather than at invocation, catching configuration errors early in the development cycle
vs alternatives: Simpler tool definition API than raw MCP SDK while maintaining full schema expressiveness; automatic schema validation prevents runtime errors that would occur with manual JSON-RPC message handling
Allows servers to expose resources (files, documents, data) to MCP clients through a resource registry with URI-based addressing. Supports streaming large resources via chunked responses and lazy-loading content, preventing memory bloat when exposing large datasets. Resources are discoverable via the MCP resources/list endpoint and can be fetched with optional filtering and pagination parameters.
Unique: Implements MCP's resource streaming protocol with built-in support for chunked responses and lazy content loading; abstracts the complexity of managing resource lifecycle and metadata discovery through a simple registry pattern
vs alternatives: More efficient than exposing resources via REST endpoints because it uses MCP's native streaming and avoids HTTP overhead; integrates seamlessly with Claude's context window management
Enables servers to define reusable prompt templates that MCP clients can discover and instantiate with dynamic arguments. Templates support variable substitution, conditional sections, and metadata for client-side UI hints (e.g., input field types). The runtime manages template registration and provides clients with the prompts/list and prompts/get endpoints for discovery and instantiation.
Unique: Provides a lightweight prompt template system integrated with MCP's native prompts endpoint; supports variable substitution and metadata hints without requiring a full templating engine like Handlebars or Jinja2
vs alternatives: Simpler than managing prompts in client code because templates are server-defined and discoverable; more flexible than hardcoded prompts because clients can customize variables at invocation time
Implements the MCP JSON-RPC 2.0 message protocol with automatic request routing to registered handlers, response serialization, and error handling. Routes incoming messages to appropriate tool handlers, resource readers, or prompt resolvers based on method names; catches exceptions and converts them to MCP-compliant error responses with proper error codes and messages. Handles both request-response and notification patterns.
Unique: Abstracts MCP's JSON-RPC 2.0 message routing through a handler registry pattern; automatically converts exceptions to MCP-compliant error responses without requiring manual error code mapping
vs alternatives: Reduces boilerplate compared to manual JSON-RPC parsing; ensures protocol compliance automatically, preventing subtle bugs that would break compatibility with strict MCP clients
Manages incoming client connections, performs MCP protocol version negotiation, and maintains connection state throughout the server's lifetime. Handles the initialization handshake where clients declare their capabilities and the server responds with its supported features. Manages connection cleanup and graceful disconnection, including resource teardown for long-lived connections.
Unique: Handles MCP protocol negotiation as part of the server initialization flow; maintains connection state and capability tracking without requiring manual state management in application code
vs alternatives: Simpler than implementing protocol negotiation manually; ensures compatibility with different MCP client versions through automatic capability matching
Exposes the server's ability to request sampling (LLM inference) from connected clients through the sampling/create endpoint. Allows servers to invoke language models on the client side (e.g., Claude running in Claude Desktop) with specified prompts, model parameters, and system instructions. Responses are streamed back to the server, enabling agentic patterns where servers can reason about tool results and decide next steps.
Unique: Enables server-initiated sampling through MCP's sampling/create endpoint; allows servers to invoke the client's LLM without API keys, enabling secure agentic patterns where reasoning happens on the client side
vs alternatives: More secure than servers making direct API calls because credentials stay on the client; enables tighter integration with Claude Desktop's native capabilities compared to REST-based tool calling
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 @pikku/modelcontextprotocol at 21/100.

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
