Bootstraps a Model Context Protocol server using Solid.js as the reactive UI framework, establishing bidirectional communication channels between MCP clients and server resources. Implements the MCP transport layer with Solid's reactive primitives for state management, enabling real-time synchronization of tool definitions, resources, and prompts without manual subscription management.
Unique: Combines MCP server architecture with Solid.js reactivity model, using Solid's createSignal and createEffect primitives to automatically propagate tool/resource changes to connected clients without explicit subscription boilerplate
vs alternatives: Lighter than Express-based MCP servers with automatic reactive state management, versus manual event emitter patterns in vanilla Node.js MCP implementations
Exposes server-side tools (functions) to MCP clients through standardized tool schema definitions, implementing the MCP tools/list and tools/call endpoints. Each tool is registered with input schema validation, description metadata, and execution handlers that integrate with Solid's reactive system to track tool invocations and results.
Unique: Integrates tool execution with Solid.js reactive signals, allowing tool results to automatically trigger UI updates and dependent computations without manual state management
vs alternatives: More declarative than manual event-driven tool systems; automatic reactivity reduces boilerplate compared to Redux or Context API patterns in React-based MCP servers
Exposes server-side resources (files, data, documents) to MCP clients through the MCP resources/list and resources/read endpoints, with support for text and binary content streaming. Resources are registered with URI patterns, MIME types, and read handlers that leverage Solid's reactive system to notify clients of resource updates in real-time.
Unique: Combines MCP resource streaming with Solid.js reactive signals, enabling automatic client notifications when resources change without explicit polling or WebSocket subscription management
vs alternatives: More efficient than REST-based file serving for MCP clients; reactive updates eliminate polling overhead compared to static resource endpoints
Registers reusable prompt templates with the MCP prompts/list and prompts/get endpoints, supporting parameterized prompts with argument schemas and default values. Templates are stored reactively and can be composed with tool and resource context, enabling clients to request pre-built prompts tailored to specific tasks without crafting raw text.
Unique: Integrates prompt templates with MCP's tool and resource context, allowing prompts to reference available tools and resources dynamically without hardcoding specific tool names or file paths
vs alternatives: More flexible than static prompt files; reactive template updates enable real-time prompt changes without server restart, versus traditional prompt management systems
Leverages Solid.js createSignal and createEffect primitives to maintain reactive state that automatically synchronizes with connected MCP clients. Changes to tools, resources, or prompts trigger reactive updates that propagate to all clients without manual event handling, implementing a push-based notification model instead of pull-based polling.
Unique: Uses Solid.js fine-grained reactivity (createSignal/createEffect) to automatically track and propagate MCP state changes, eliminating manual subscription/unsubscription patterns required in event-emitter-based servers
vs alternatives: More efficient than Redux or Zustand for MCP state management because Solid's fine-grained reactivity only updates affected clients, versus broadcasting all state changes to all subscribers
Abstracts MCP transport mechanisms (stdio, HTTP, WebSocket) behind a unified interface, handling JSON-RPC 2.0 message parsing, routing, and response serialization. The server automatically maps incoming MCP requests to tool/resource/prompt handlers and returns properly formatted responses, with error handling for malformed messages and missing handlers.
Unique: Provides a unified MCP transport abstraction that works with Solid.js reactive state, automatically triggering reactive updates when messages arrive without explicit event listener registration
vs alternatives: Simpler than building transport handlers manually; automatic routing and error handling reduce boilerplate compared to raw JSON-RPC server implementations
Serves as a reference implementation demonstrating best practices for building MCP servers with Solid.js, including tool registration patterns, resource exposure patterns, prompt template patterns, and reactive state management. The example code is structured to be copy-paste-friendly for developers starting new MCP projects.
Unique: Combines MCP protocol documentation with Solid.js reactive patterns in a single runnable example, showing how to leverage Solid's fine-grained reactivity for efficient MCP state management
vs alternatives: More practical than abstract MCP documentation because it provides working code; more focused than generic Solid.js tutorials because it's MCP-specific
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 @modelcontextprotocol/server-basic-solid at 21/100.

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
