Creates an MCP request handler that bridges the Model Context Protocol with HTTP/SSE transports by accepting a configuration object with tool definitions and returning a request processor. The handler auto-detects transport type (HTTP vs SSE) and routes requests through a unified processing pipeline that validates tool schemas using Zod, executes registered tools, and streams responses back to clients with proper MCP protocol framing.
Unique: Implements transport auto-detection at the handler level, allowing a single createMcpHandler call to serve both HTTP and SSE clients without conditional logic, using Zod for compile-time type safety on tool schemas rather than runtime JSON schema validation
vs alternatives: Simpler than building raw MCP servers because it abstracts protocol framing and transport negotiation, while maintaining full type safety through Zod schema inference that catches tool definition errors at development time
Wraps MCP handlers with OAuth 2.0 RFC 9728 (OAuth for Interoperable Claiming) compliant authentication that enforces scope verification before tool execution. The wrapper intercepts requests, validates bearer tokens against configured scopes, and rejects unauthorized access with proper OAuth error responses, integrating with the MCP protocol's authentication flow without requiring external auth services.
Unique: Implements RFC 9728 compliant OAuth for MCP specifically, wrapping handlers as middleware rather than requiring per-tool auth logic, with automatic scope validation that integrates into the MCP request pipeline before tool execution
vs alternatives: More lightweight than building custom JWT verification per endpoint because it centralizes auth logic in a single wrapper, while maintaining MCP protocol compliance without requiring external auth middleware or API gateway configuration
Enables developers to define MCP tools with full TypeScript type inference, where tool input/output types are automatically inferred from Zod schemas and function signatures. The adapter uses TypeScript's type system to ensure tool definitions are consistent with their implementations, catching type mismatches at compile time and providing IDE autocomplete for tool parameters.
Unique: Leverages TypeScript's type inference system to automatically derive tool input/output types from Zod schemas, providing compile-time type checking without requiring separate type definitions, with IDE integration for autocomplete
vs alternatives: More type-safe than runtime-only validation because TypeScript catches errors at compile time, while less verbose than manual type definitions because types are inferred from schemas
Allows configuration of maximum SSE connection duration and request timeout values, enabling operators to control resource usage and prevent long-lived connections from consuming server resources indefinitely. The adapter enforces configurable timeouts (default 60 seconds for SSE) that automatically close connections when exceeded, with graceful error handling that notifies clients of timeout conditions.
Unique: Provides built-in timeout enforcement for SSE connections with configurable duration limits, automatically closing connections when exceeded and notifying clients, without requiring external timeout middleware
vs alternatives: Simpler than implementing custom timeout logic because it's built into the SSE transport handler, while more reliable than relying on framework timeouts because it's MCP-aware and provides proper error responses
Enables detailed logging of MCP request/response cycles, tool invocations, and authentication events through a configurable verbose logging mode. When enabled, the adapter logs request headers, tool parameters, execution results, and error details to console or logging system, facilitating debugging of MCP client integration issues and tool execution problems without requiring external debugging tools.
Unique: Provides built-in verbose logging specifically for MCP protocol details, logging request/response cycles and tool invocations without requiring external debugging tools, with configurable enable/disable flag
vs alternatives: More convenient than external debugging tools because it's built into the adapter and logs MCP-specific details, while simpler than implementing custom logging because it's a single configuration flag
Automatically generates OAuth 2.0 protected resource metadata endpoints (/.well-known/oauth-protected-resource) that advertise MCP server capabilities, required scopes, and resource URIs to OAuth clients. The metadata handler returns JSON conforming to OAuth protected resource metadata standards, enabling clients to discover what scopes are needed before attempting authentication.
Unique: Provides automatic metadata endpoint generation specifically for MCP servers, handling CORS headers and OAuth format compliance without requiring manual endpoint implementation, integrated with the authentication system to advertise actual configured scopes
vs alternatives: Eliminates manual metadata endpoint coding by auto-generating RFC-compliant responses, while integrating with the adapter's scope configuration to keep metadata in sync with actual auth requirements
Automatically detects whether incoming requests expect HTTP streaming or Server-Sent Events (SSE) responses and routes them through appropriate transport handlers. The adapter inspects request headers (Accept, Connection) and query parameters to determine transport type, then streams tool results using the detected mechanism without requiring explicit client configuration or separate handler implementations.
Unique: Implements transport detection at the handler level using header inspection and query parameter analysis, allowing a single handler to serve both HTTP and SSE clients without branching logic, with automatic format conversion for MCP protocol messages
vs alternatives: More flexible than fixed-transport servers because it adapts to client capabilities at request time, while simpler than implementing separate HTTP and SSE endpoints because transport negotiation is transparent to tool code
Optionally persists Server-Sent Events session state to Redis, enabling clients to reconnect and resume interrupted streams without losing tool execution context. When configured with a Redis URL, the adapter stores session metadata (tool invocation state, partial results) in Redis with configurable TTL, allowing clients to reconnect using a session token and continue receiving results from where they left off.
Unique: Integrates Redis persistence directly into the SSE transport layer, storing session state with automatic TTL management and session token generation, enabling transparent reconnection without requiring clients to implement session recovery logic
vs alternatives: More resilient than in-memory session storage because it survives server restarts and works across multiple instances, while simpler than implementing custom session management because Redis integration is built-in with automatic serialization

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
