BlockVectra MCP: Robinhood Chain and multi-chain EVM tools in Gemini CLI

[gjwang]

BlockVectra is a remote Streamable HTTP MCP server for Robinhood Chain and multiple EVM networks. Chain discovery and docs work without a key. RPC access follows each chain's policy, while Data API and account tools need an API key.

Install:

gemini extensions install https://github.com/blockvectra/mcp --ref main

Guide: https://docs.blockvectra.com/en/guides/mcp-server/

Verified with native Gemini CLI 0.65.0: install succeeded, 15 tools were discovered, and keyless list_chains and read_doc calls passed.
