Add it as a custom connector with this URL (Streamable HTTP):

https://mcp.blockreq.com/mcp

This server expects extra headers, usually an API key from its maker.

Tools it offers

6 tools, as the server itself reported during our check on Oct 31, 2026.

• list_chainsList every published BlockReq network with its host, public trial URL, private URL pattern ({API_KEY} placeholder), WSS support, and archive and proof/debug/trace flags.
• get_chainGet one network's URLs and capability flags, its API reference page, and (for EVM networks) the JSON-RPC methods documented for it.
• search_docsSearch the BlockReq docs (setup, API keys, endpoints, Request Counting, plans, networks, support). Returns page titles, URLs, Markdown URLs for get_doc_page, and snippets. Chinese queries search the Chinese pages.
• get_doc_pageRead one BlockReq docs page as Markdown. Accepts a https://blockreq.com/docs/... URL (HTML or index.md) or a path such as /docs/getting-started/.
• get_method_referenceGet the documented parameters, result, example, and endpoints of one JSON-RPC method on one EVM network, from BlockReq's OpenRPC document.
• call_rpcCall 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 BlockR
