list_chainsread-onlyList 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_chainread-onlyGet one network's URLs and capability flags, its API reference page, and (for EVM networks) the JSON-RPC methods documented for it.
search_docsread-onlySearch 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-onlyRead 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_referenceread-onlyGet the documented parameters, result, example, and endpoints of one JSON-RPC method on one EVM network, from BlockReq's OpenRPC document.
call_rpcread-onlyCall 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,
