Implements a policy-driven authorization layer that intercepts MCP tool invocations before execution, evaluating them against declarative permission rules. Uses a schema-based rule engine that matches tool names, parameters, and caller context against predefined policies, blocking or allowing calls based on configurable access control lists and role-based permissions.
Unique: Operates as an MCP-native middleware layer that enforces authorization at the protocol level rather than at the application layer, enabling transparent policy enforcement across any MCP-compatible client without modifying tool implementations or client code.
vs alternatives: Unlike generic API gateway authorization (Kong, Envoy), tegata understands MCP semantics and tool schemas natively, enabling fine-grained parameter-level access control without requiring separate proxy infrastructure.
Provides a mechanism to flag certain tool calls as requiring human approval before execution, routing them to a notification/approval system that can accept or reject the call. Implements a callback-based approval pattern where blocked calls are queued with context (tool name, parameters, reason for block) and can be asynchronously approved by authorized humans.
Unique: Integrates approval workflows directly into the MCP protocol layer, allowing approval decisions to be enforced before tool execution rather than as a post-execution audit, enabling true preventive governance rather than detective controls.
vs alternatives: More lightweight than building approval workflows with separate workflow orchestration platforms (Zapier, n8n) because it operates at the MCP middleware level, avoiding context serialization and external service latency.
Evaluates tool calls against declarative authorization policies that can match on tool names, parameter values, parameter types, and caller attributes. Uses a rule matching engine that supports conditions like 'allow tool X only if parameter Y matches pattern Z' or 'deny tool X for all callers except role admin', enabling granular control over which tools can be called with which inputs.
Unique: Operates at the parameter level rather than just tool level, enabling policies that understand the semantic impact of tool calls (e.g., 'allow delete_user only if user_id is not in protected_list'), not just which tools are accessible.
vs alternatives: More expressive than simple role-based access control (RBAC) because it can enforce context-aware policies; simpler than full attribute-based access control (ABAC) systems because it doesn't require external policy engines.
Automatically logs all tool call attempts (allowed, denied, and approval-required) with metadata including caller identity, tool name, parameters, authorization decision, timestamp, and reason for allow/deny. Generates structured audit logs compatible with compliance frameworks, enabling forensic analysis and compliance reporting for regulatory requirements.
Unique: Captures authorization decisions at the MCP protocol level, creating a complete audit trail of agent tool access that is independent of application-level logging, ensuring compliance-grade immutability and completeness.
vs alternatives: More comprehensive than application-level logging because it captures all tool call attempts (including denied ones) at the middleware layer; more specialized for AI governance than generic audit logging systems.
Implements role-based authorization where agents or callers are assigned roles (e.g., 'admin', 'analyst', 'viewer') and tools are restricted to specific roles. Uses a role-to-tool mapping system where authorization decisions are made by checking if the caller's role has permission for the requested tool, enabling simple but scalable access control for multi-agent systems.
Unique: Applies RBAC specifically to MCP tool access, enabling role-based governance of agent capabilities at the protocol level rather than requiring application-level role checks in each tool implementation.
vs alternatives: Simpler to understand and implement than attribute-based access control (ABAC) for teams new to authorization; more scalable than per-agent tool whitelists because roles can be reused across many agents.
Integrates with MCP servers as a middleware layer that transparently intercepts all tool call requests before they reach tool implementations. Uses the MCP protocol's request/response model to inject authorization checks without requiring changes to tool code or client code, enabling drop-in authorization enforcement for existing MCP servers.
Unique: Operates as a protocol-level middleware that intercepts MCP messages, enabling authorization enforcement without requiring tool implementations to be aware of or implement authorization logic, achieving true separation of concerns.
vs alternatives: More transparent than requiring each tool to implement authorization checks; more efficient than proxying MCP calls through a separate authorization service because it operates in-process.
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 tegata at 23/100. tegata 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
