Transport

streamable-http

Getting Started

Connect to https://docs.blockvectra.com/mcp using Streamable HTTP. claude mcp add --transport http blockvectra https://docs.blockvectra.com/mcp Start without an API key: call list_chains, then read_doc with path=quickstart and lang=en. Check chain identity and method policy before making RPC calls. Indexed Data API and account tools require your own BlockVectra API key, supplied privately in x-api-key headers; never paste it into chat. rpc_call is read-only. send_raw_transaction broadcasts an already-signed transaction and follows the selected chain's broadcast policy; the server does not sign or accept private keys.
