Implements a Model Context Protocol (MCP) server that handles bidirectional JSON-RPC communication with MCP clients (Claude, other LLMs). Manages server initialization, resource discovery, tool registration, and graceful shutdown through the MCP specification's lifecycle hooks. Uses stdio or SSE transport layers to establish persistent connections with client applications.
Unique: unknown — insufficient data on specific MCP server implementation details (transport choice, resource caching strategy, error handling patterns)
vs alternatives: unknown — insufficient data on how this MCP server differs from other MCP implementations in performance, feature completeness, or developer experience
Provides a declarative interface for registering tools with JSON Schema definitions that describe input parameters, return types, and tool metadata. Tools are exposed to MCP clients through a schema registry that enables type-safe function calling with automatic validation and error handling. Supports tool discovery by clients and dynamic tool availability based on runtime conditions.
Unique: unknown — insufficient data on whether this uses JSON Schema validation, OpenAPI schema support, or custom schema formats
vs alternatives: unknown — insufficient data on how tool registration compares to OpenAI function calling, Anthropic tool_use, or other MCP tool implementations
Exposes static and dynamic resources (files, templates, data, documentation) to MCP clients through a resource URI scheme. Resources are served with MIME type metadata and can be streamed or cached. Supports resource templates with variable substitution and dynamic resource generation based on client requests, enabling clients to access backend data without direct API calls.
Unique: unknown — insufficient data on resource caching strategy, streaming implementation, or template variable substitution approach
vs alternatives: unknown — insufficient data on how resource serving compares to RAG systems, file-based context injection, or other MCP resource implementations
Registers reusable prompt templates that MCP clients can discover and invoke with variable substitution. Templates are stored server-side with argument schemas, allowing clients to request prompt execution with specific parameters. Supports dynamic prompt generation based on client context and enables consistent prompt patterns across multiple client sessions.
Unique: unknown — insufficient data on template syntax, variable substitution mechanism, or prompt versioning strategy
vs alternatives: unknown — insufficient data on how prompt templates compare to client-side prompt engineering, prompt management platforms, or other MCP prompt implementations
Provides a sampling interface that allows MCP clients to request model completions through the server, enabling server-side model selection, parameter tuning, and response processing. Supports multiple model providers (OpenAI, Anthropic, local models) with unified API, allowing clients to invoke models without managing API keys or provider-specific logic. Responses can be streamed or buffered with optional post-processing.
Unique: unknown — insufficient data on supported model providers, streaming implementation, or response post-processing capabilities
vs alternatives: unknown — insufficient data on how sampling compares to direct model API calls, LiteLLM, or other MCP sampling implementations
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 lunar-mcp-server at 24/100. lunar-mcp-server 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
