Available tools 18

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

evm

evm_broadcastTransaction

Preflight and broadcast an already-signed EVM transaction. Disabled unless ALLOW_EVM_BROADCAST=true; never signs or stores keys.

evm_call

Run a read-only eth_call with pre-encoded calldata. This never submits a transaction.

evm_estimateTransaction

Estimate gas for an unsigned EVM transaction. Values are accepted as decimal or hex quantities.

evm_getBlock

Read an EVM block by number, tag, or block hash.

evm_getBlockNumber

Return the latest EVM block number from the configured endpoint.

evm_getChainInfo

Return the EVM chain ID and upstream client version.

evm_getLogs

Read EVM event logs using an address/topics filter and bounded block range.

evm_getNativeBalance

Read an address native-token balance at an EVM block without requiring a wallet.

evm_getTransaction

Read an EVM transaction and its receipt by transaction hash.

evm_readContract

Encode, execute, and decode a read-only smart-contract function using a supplied JSON ABI.

btc

btc_broadcastTransaction

Validate and broadcast an already-signed Bitcoin transaction. Disabled unless ALLOW_BITCOIN_BROADCAST=true; never signs or stores keys.

btc_decodeRawTransaction

Decode a serialized Bitcoin transaction without broadcasting it.

btc_estimateFee

Estimate a Bitcoin fee rate for confirmation within a target number of blocks.

btc_getAddressBalance

Scan the Bitcoin UTXO set for an address and return its confirmed spendable outputs. This is not address history and shared RPC nodes may reject concurrent scans.

btc_getBlock

Read a Bitcoin block by height or hash with selectable verbosity.

btc_getBlockchainInfo

Return Bitcoin network, chain height, sync, and pruning information.

btc_getTransaction

Read a raw Bitcoin transaction by txid. A block hash can make confirmed transaction lookup more reliable.

btc_getTxOut

Read an unspent Bitcoin transaction output. Returns null when the output is spent or unknown.

ChainRPC MCP — questions

Answers built from our own checks of this server.

What can ChainRPC MCP do?

It exposes 18 tools, read directly from the server on our last check. Among them: btc_broadcastTransaction, btc_decodeRawTransaction, btc_estimateFee, btc_getAddressBalance, btc_getBlock, btc_getBlockchainInfo and 12 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is ChainRPC MCP mostly used for?

Its tools cluster around evm and btc. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is ChainRPC MCP working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 70 ms. The bar chart above shows every period we have measured.

The registry lists ChainRPC MCP as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect ChainRPC MCP?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does ChainRPC MCP need an API key?

No. ChainRPC MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 18 of them are readable on this page. This is what we observed, not what the docs claim.

How many people use ChainRPC MCP?

The npm package chainrpc-mcp was installed 51 times in the last week. Week over week that is -18%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is ChainRPC MCP open source?

The code is open source: it is published under the MIT licence, written in JavaScript and 4 stars on GitHub. The licence covers the code in the repository, not the hosted service at chainrpc-mcp.mitander.io, which runs on its operator's own terms.
