Implements OAuth 2.0 and OpenID Connect (OIDC) authentication flows as a plug-and-play MCP server capability, handling authorization code exchange, token validation, and identity provider integration. Uses standard OAuth/OIDC protocols to delegate authentication to external identity providers (Google, GitHub, Auth0, etc.) rather than managing credentials directly, reducing security surface area and enabling single sign-on across MCP clients.
Unique: Purpose-built as a drop-in MCP server capability rather than a generic OAuth library, abstracting MCP-specific authentication patterns and reducing boilerplate for MCP developers integrating external identity providers
vs alternatives: Simpler than building OAuth integration manually with passport.js or similar libraries because it's tailored specifically to MCP server architecture and protocols
Validates authentication tokens within the MCP request/response lifecycle, managing session state and enforcing token expiration policies at the MCP server level. Intercepts MCP tool calls and resource requests to verify valid authentication before execution, implementing middleware-style authentication guards that integrate with MCP's resource and tool calling architecture rather than HTTP-level middleware.
Unique: Implements authentication validation at the MCP protocol layer (tool calls, resource requests) rather than HTTP transport layer, enabling fine-grained per-capability access control within MCP's resource and tool calling model
vs alternatives: More granular than HTTP-level authentication because it validates at the MCP message level, allowing different authentication policies per tool or resource
Abstracts multiple OAuth/OIDC providers behind a unified authentication interface, allowing MCP clients to authenticate via any configured provider (Google, GitHub, Auth0, custom OIDC) without client-side provider selection logic. Routes authentication requests to the appropriate provider based on configuration or client hints, normalizing user identity attributes across providers into a consistent schema.
Unique: Provides provider-agnostic authentication abstraction specifically for MCP servers, handling provider routing and identity normalization transparently rather than requiring clients to specify providers
vs alternatives: Simpler than implementing provider-specific logic in each MCP client because the server handles all provider routing and normalization centrally
Manages OAuth token lifecycle including refresh token handling, automatic token renewal, and credential rotation for long-lived MCP server sessions. Implements refresh token grant flows to obtain new access tokens before expiration, storing and rotating credentials securely, and handling provider-specific token refresh policies (expiration windows, refresh token rotation, etc.).
Unique: Automates token refresh at the MCP server level, handling provider-specific refresh policies and rotation strategies transparently without requiring client-side refresh logic
vs alternatives: More reliable than client-side token refresh because the server manages refresh proactively before expiration, preventing authentication failures mid-session
Enforces fine-grained access control on MCP resources and tool calls based on authenticated user identity and claims, implementing authorization policies that map user attributes (roles, scopes, groups) to specific MCP capabilities. Integrates with MCP's resource and tool calling architecture to gate access before execution, supporting both role-based access control (RBAC) and attribute-based access control (ABAC) patterns.
Unique: Implements authorization at the MCP tool/resource level rather than HTTP endpoint level, enabling per-capability access control that aligns with MCP's resource and tool calling model
vs alternatives: More granular than HTTP-level authorization because it can enforce different policies per MCP tool or resource within a single endpoint
Provides secure storage for sensitive authentication data (client secrets, refresh tokens, API keys) with encryption at rest and integration with external secrets management systems (AWS Secrets Manager, HashiCorp Vault, etc.). Abstracts credential retrieval and rotation, preventing secrets from being logged or exposed in configuration files, and supporting key rotation policies.
Unique: Provides MCP-specific credential management patterns, abstracting secrets storage and rotation for OAuth/OIDC credentials used by MCP servers rather than generic secrets management
vs alternatives: More specialized than generic secrets managers because it handles OAuth-specific credential types (refresh tokens, client secrets) and rotation patterns
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 mcp-auth at 23/100. mcp-auth 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
