Generates cryptographically signed, immutable receipts for every MCP tool invocation that capture the complete decision context (model, prompt, parameters, output) and bind them to a specific mandate or governance policy. Uses a hash-chain or merkle-tree approach to create tamper-evident audit trails where any modification to prior decisions is cryptographically detectable, enabling compliance with EU AI Act transparency and accountability requirements.
Unique: Integrates cryptographic receipt generation directly into the MCP protocol layer, creating tamper-evident decision records at the point of tool invocation rather than as a post-hoc logging layer. This architectural choice ensures no decision can be made without generating a signed receipt, making governance enforcement mandatory rather than optional.
vs alternatives: Unlike generic audit logging (which can be disabled or modified), CLG's receipt system makes governance enforcement a first-class MCP protocol concern with cryptographic proof of integrity, directly addressing EU AI Act transparency mandates that require immutable decision documentation.
Intercepts MCP tool calls before execution and validates them against a set of governance mandates (policies, rules, constraints) in real-time, blocking or modifying calls that violate policy. Implements a policy evaluation engine that can enforce constraints like rate limits, tool whitelists/blacklists, parameter validation, and conditional access rules based on model state, user context, or decision history.
Unique: Embeds policy evaluation as a mandatory gate in the MCP tool invocation pipeline, enforcing mandates synchronously before tool execution rather than logging violations asynchronously. This ensures governance is enforced at the point of decision, not discovered after the fact.
vs alternatives: Provides real-time, synchronous mandate enforcement integrated into MCP's native tool-calling mechanism, whereas generic policy engines typically operate as external audit layers that detect violations post-execution, making CLG's approach preventative rather than detective.
Wraps standard MCP tool definitions and invocations to automatically inject governance metadata (mandate IDs, policy context, decision timestamps, audit identifiers) into the protocol layer. Extends MCP's native schema to carry governance context through the entire tool call lifecycle, enabling downstream systems to understand the governance context in which each decision was made without requiring separate metadata channels.
Unique: Operates at the MCP protocol layer itself, injecting governance metadata directly into tool definitions and invocations rather than as a separate metadata channel. This ensures governance context is native to the protocol and cannot be bypassed or ignored by downstream systems.
vs alternatives: Unlike external governance layers that operate parallel to MCP, this wrapper makes governance a first-class concern in the protocol itself, ensuring all MCP implementations automatically carry governance context without requiring separate integration work.
Automatically generates compliance documentation artifacts (decision logs, impact assessments, audit reports) formatted to satisfy EU AI Act requirements for high-risk AI systems. Aggregates decision receipts, mandate enforcement records, and governance metadata into structured reports that demonstrate transparency, accountability, and human oversight requirements mandated by the regulation.
Unique: Generates EU AI Act-specific compliance documentation directly from the cryptographic decision receipts and mandate enforcement logs, ensuring regulatory reports are grounded in tamper-evident evidence rather than reconstructed from logs that could be modified.
vs alternatives: Produces compliance documentation that is directly tied to cryptographically signed decision receipts, providing regulators with verifiable proof of governance enforcement, whereas generic audit logging systems produce reports that lack cryptographic integrity guarantees.
Captures and stores the complete decision context for every tool call (model version, prompt, parameters, output, timestamp, user/system context) in a structured format that can be retrieved and analyzed for audit purposes. Implements a queryable audit store that allows filtering and searching decisions by mandate, tool, timestamp, or outcome, enabling post-hoc analysis of system behavior and decision patterns.
Unique: Preserves complete decision context (not just outcomes) in a queryable store, enabling post-hoc analysis and reconstruction of the reasoning that led to specific tool calls. This goes beyond simple logging by maintaining the full decision context needed for regulatory explanation.
vs alternatives: Provides queryable, context-rich audit trails that preserve the complete decision reasoning, whereas generic logging systems typically only record outcomes, making it difficult to reconstruct why a specific decision was made.
Binds tool calls to specific model identifiers and execution context (user ID, request ID, session ID) so that decisions can be traced back to the specific model instance and user interaction that triggered them. Implements context propagation through the MCP call stack to ensure governance metadata is associated with the correct model and user.
Unique: Implements context binding at the MCP protocol level so that model identity and user context are automatically propagated through tool call chains without requiring explicit context passing at each step. Uses a context propagation pattern similar to distributed tracing systems.
vs alternatives: More reliable than application-level context tracking because it's embedded in the MCP stack and cannot be bypassed, whereas application-level approaches depend on developers correctly passing context through their code.
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 @clgplatform/mcp at 27/100.

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
