https://blazephoenix.xyz/mcpBlockVectra: multi-chain RPC & Data API
by Master King
BlockVectra MCP connects AI agents to multi-chain EVM RPC and indexed Data API tools. Documentation, chain discovery, status, pricing and supported public RPC reads are keyless. Data API and account tools require your own BlockVectra API key; access to RPC methods depends on each chain's public method policy. Connect to the hosted Streamable HTTP endpoint or use the MIT-licensed stdio bridge with Node.js 22+. A separate tool can broadcast an already signed transaction; never supply private keys.
