Measured tools (6)

• list_chains read-only

  List 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.

  Parameters:

  • network_type — string — Only this network type

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_chain read-only

  Get one network's URLs and capability flags, its API reference page, and (for EVM networks) the JSON-RPC methods documented for it.

  Parameters:

  • chain (required) — string — Network slug (for example ethereum, base, arbitrum-sepolia), catalog id, hostname, name, or EVM chain ID (1 or 0x1)

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• search_docs read-only

  Search 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.

  Parameters:

  • query (required) — string — Words to search for
  • limit — integer — Most results to return (default 5)
  • locale — string — Docs language; defaults to the query's language

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_doc_page read-only

  Read 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/.

  Parameters:

  • url (required) — string — Docs page URL or path

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_method_reference read-only

  Get the documented parameters, result, example, and endpoints of one JSON-RPC method on one EVM network, from BlockReq's OpenRPC document.

  Parameters:

  • chain (required) — string — Network slug (for example ethereum, base, arbitrum-sepolia), catalog id, hostname, name, or EVM chain ID (1 or 0x1)
  • method (required) — string — JSON-RPC method, for example eth_getLogs

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• call_rpc read-only

  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.

  Parameters:

  • chain (required) — string — Network slug (for example ethereum, base, arbitrum-sepolia), catalog id, hostname, name, or EVM chain ID (1 or 0x1)
  • method (required) — string
  • params — array — Positional JSON-RPC params; a missing block parameter means latest

  Hints: read-only yes · destructive no · idempotent no · open-world yes
