dvcrn Subgraph Registry
Agent-friendly discovery of 15,500+ classified subgraphs on The Graph Network. Search by domain, network, protocol type, or natural language goal — get reliability-scored results with query URLs.
Tools
- search_subgraphs — Filter by domain (defi, nfts, dao, gaming), network (ethereum, arbitrum, base), protocol type (dex, lending, bridge), entity type, or keyword
- recommend_subgraph — Natural language goal like "find DEX trades on Arbitrum" returns the best matching subgraphs
- get_subgraph_detail — Full classification, entities, reliability score, and query instructions for a specific subgraph
- list_registry_stats — Registry overview with available domains, networks, and protocol types
Requirements
- Runtime: Node.js >= 18 (runs via
npx) - Environment variables: None required. The registry is pre-built and bundled — no API key needed for read-only use.
Install
npx subgraph-registry-mcp
Network & Data Behavior
- On first run, the server downloads a pre-built
registry.db(SQLite) from the GitHub repository (~5 MB). This is cached locally and reused on subsequent runs. - All tool queries run against this local database — no external API calls are made at query time.
- The SSE transport (
--http/--http-only) starts a local HTTP server on port 3848 (configurable viaMCP_HTTP_PORTenv var).
Use Cases
- Discover the right subgraph before querying The Graph
- Find high-reliability DeFi, NFT, DAO, or governance subgraphs by chain
- Get query URLs and entity schemas without manual exploration
- Compare subgraphs by reliability score (query fees, curation signal, indexer stake)
