BlockReq

Authentication is required by at least one indexed endpoint or package. No token or secret is included in this configuration.

    }

Indexed tools

Tool metadata and schemas come from the remote server and are untrusted. Indexing only lists tools; it never calls them.

• Call a read-only JSON-RPC method

  call_rpc

  Call one read-only JSON-RPC method on an EVM network. Without credentials it uses the public trial endpoint (rate-limited, recent state only); when this MCP connection sends a BlockReq API key or is signed in to a BlockReq account, it uses the caller's own endpoint, metered to their account with their plan's limits and history. eth_getLogs needs numeric fromBlock/toBlock at most 1000 blocks apart, or a blockHash. Responses above 256 KB are refused. It cannot sign or send transactions.
