{"entry":{"slug":"blockvectra-mcp","name":"BlockVectra","category":"mcp","summary":"Find sourced EVM and Robinhood Chain docs, discover chain capabilities, read RPC and indexed data, and broadcast externally signed transactions. Access and coverage depend on the tool and chain.","description":"Connect without an account or wallet to search_docs, read_doc and list_chains. Use the chain catalog to select a supported network and its public methods. Indexed Data API and account tools require a caller-supplied API key; restricted RPC methods require a key too. Supply keys only through MCP client HTTP headers, never tool arguments or chat. Dataset availability and historical coverage vary by chain. send_raw_transaction broadcasts a transaction signed outside this server; the server does not hold private keys or sign for the caller. Do not label the whole server read-only. Docs and discovery access is distinct from paid service use.","auth_mode":"Keyless docs/discovery; x-api-key for Data/account and restricted RPC","endpoint":"https://docs.blockvectra.com/mcp","docs_url":"https://docs.blockvectra.com/en/guides/mcp-server/?ref=agent-nexus-20261103","tags":["blockchain","evm","robinhood-chain","rpc","indexed-data","documentation"],"capabilities":["search-blockchain-docs","read-blockchain-docs","discover-chain-capabilities","read-chain-status","estimate-rpc-usage","read-json-rpc","query-indexed-chain-data","read-api-key-account","broadcast-signed-transactions"],"auth_params":[{"name":"x-api-key","location":"header","required":false}],"input_format":"MCP JSON-RPC over Streamable HTTP","output_format":"MCP JSON-RPC tool results","rate_limit":"RPC quotas vary by chain and public/keyed access; consult list_chains.","pricing":"Documentation and discovery are keyless; keyed service usage follows published CU pricing.","invocation_example":"claude mcp add --transport http blockvectra-docs https://docs.blockvectra.com/mcp","verified":false,"verified_at":null,"featured":false,"checks_total":1,"checks_ok":1,"avg_latency_ms":135,"reports_count":0,"health_ok":true,"health_status_code":405,"health_checked_at":"2026-11-03T08:17:01.451+00:00","health_latency_ms":135,"probe_url":null},"watch":{"hint":"Follow \"blockvectra-mcp\": get alerted when it goes down, comes back, or changes shape.
