BlockReq MCP: EVM networks and RPC methods in your editor

Give your coding agent BlockReq's docs and RPC

1. 1Click Connect BlockReq free. There's no sign-in, so its tools are ready at once.
2. 2Five tools read BlockReq's docs and catalog, and `call_rpc` makes read-only calls to EVM networks. Keep them all for development, or switch off `call_rpc` if you only want documentation.
3. 3Add ContextGate to your AI app as a connector or MCP server. The steps for each app are on the Works with page.
4. 4Ask Cursor for the latest block number on Ethereum through BlockReq, then open Activity to see the `call_rpc` call.

Building on EVM chains with BlockReq

• List every BlockReq network with its URLs, WSS support and archive support using `list_chains`.
• Read a JSON-RPC method's parameters, result and example with `get_method_reference`.
• Search the docs on setup, API keys and plans with `search_docs`.
• Make a read-only call, such as a balance check, with `call_rpc`.

Where your RPC calls go

• Switch off `call_rpc` and your AI app can read the docs but not query a chain.
• A policy can block a BlockReq API key pasted into a prompt from leaving in a call.
• Activity records every docs lookup and RPC call.

What you get with BlockReq and ContextGate

• Your AI apps can use BlockReqClaude, Cursor, ChatGPT and other AI apps reach BlockReq through the one ContextGate connection you add to them.
• You choose which tools they can useSwitch off any BlockReq tool you don't want used. It's hidden from your AI apps and refused if called.
• Every call is checked and recordedYour policies check each call (for example, personal data is hidden and secrets are blocked), and Activity keeps a record of it.

ContextGate sees only the tool calls that go through it, not your AI app's built-in tools or your chats.

BlockReq tools

Examples of what your AI apps can do in BlockReq. You'll see the exact list of tools after you connect it.

• 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/tra
• 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, an
• 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 con
