Fetches cryptographically verifiable random numbers from the drand distributed randomness network by querying beacon endpoints and returning signed randomness values with cryptographic proofs. The MCP server acts as a bridge between Claude/LLM clients and drand's HTTP API, handling beacon selection, response parsing, and proof validation to ensure randomness integrity without requiring clients to directly interact with blockchain or distributed systems.
Unique: Implements drand integration as an MCP server, allowing LLM agents to access verifiable randomness through Claude's native tool-calling interface without requiring direct HTTP client management or cryptographic library dependencies in the agent code. Uses drand's public beacon endpoints and BLS signature verification to guarantee randomness authenticity.
vs alternatives: Unlike simple PRNG libraries or centralized randomness APIs, drand provides cryptographically-verifiable, publicly-auditable randomness that cannot be manipulated by any single entity, making it ideal for trustless AI systems; MCP integration makes it accessible to LLM agents without custom networking code.
Abstracts the complexity of selecting and querying drand beacon endpoints by providing a unified interface that handles beacon discovery, endpoint routing, and fallback logic. The server manages multiple beacon configurations (mainnet, testnet, etc.) and automatically routes requests to healthy endpoints, hiding network topology details from the LLM client.
Unique: Provides beacon endpoint abstraction at the MCP server level, allowing Claude agents to reference beacons by logical name rather than URL, with server-side configuration enabling multi-beacon support and transparent failover without agent code changes.
vs alternatives: Simpler than agents managing their own beacon endpoint lists and retry logic; more flexible than hardcoding a single drand endpoint, enabling network-agnostic agent code.
Validates drand randomness proofs using BLS signature verification to ensure that returned random values are authentic and have not been tampered with. The server performs signature validation against drand's public key material, allowing clients to trust randomness integrity without implementing cryptographic verification themselves.
Unique: Implements BLS signature verification at the MCP server boundary, validating drand proofs before returning randomness to Claude agents, ensuring agents receive only authenticated randomness without requiring cryptographic libraries in the agent runtime.
vs alternatives: Provides cryptographic assurance that alternatives like centralized randomness APIs cannot offer; validation happens server-side, reducing client complexity compared to agents implementing their own BLS verification.
Supports querying randomness for specific drand rounds or fetching the latest available round, with automatic round number management and validation. The server handles round-to-timestamp mapping and allows agents to request historical randomness (within drand's retention window) or the current round without manual round calculation.
Unique: Abstracts drand's round-based randomness model, allowing Claude agents to query by round number or request 'latest' without understanding drand's internal round timing, while preserving round metadata for audit and reproducibility.
vs alternatives: More precise than timestamp-based randomness APIs; enables reproducible randomness queries that can be audited and replayed, unlike one-time randomness generation.
Exposes drand randomness fetching as an MCP tool with a well-defined JSON schema, enabling Claude to discover, understand, and invoke randomness queries through the standard MCP tool-calling interface. The schema documents parameters, return types, and usage patterns, allowing Claude's native tool-use capabilities to orchestrate randomness-dependent workflows.
Unique: Implements drand as a first-class MCP tool with complete JSON schema, enabling Claude's native tool-use orchestration without requiring custom integration code or agent-side API management.
vs alternatives: Cleaner integration than agents managing raw HTTP calls; leverages Claude's built-in tool-use reasoning to decide when and how to invoke randomness, compared to hardcoded randomness calls in agent logic.
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 Drand at 23/100.

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
