ChainRPC MCP

JSON-RPC MCP server for EVM chains and Bitcoin

A safety-first Model Context Protocol server for EVM chains and Bitcoin.

ChainRPC MCP gives agents a focused set of tools for balances, blocks, transactions, logs, smart-contract reads, gas and fee estimation, and transaction decoding. It can submit already-signed transactions, but only behind explicit, disabled-by-default safety gates. It never accepts private keys, manages wallets, or signs transactions.

Two ecosystems, one server: EVM JSON-RPC and Bitcoin Core-compatible RPC.
Useful without an account: defaults to public Ethereum and Bitcoin endpoints from PublicNode.
Bring your own infrastructure: replace either endpoint and optionally use HTTP Basic authentication.
Official transports: local stdio and stateful Streamable HTTP through the official MCP SDK.
Constrained by design: no arbitrary RPC passthrough and no wallet, admin, debug, miner, or node-management methods.

Choose how to connect

Hosted, read-only service

The public endpoint is available now:

https://chainrpc-mcp.mitander.io/mcp

For clients that accept a remote Streamable HTTP server:

{
  "mcpServers": {
    "chainrpc-mcp": {
      "url": "https://chainrpc-mcp.mitander.io/mcp"
    }
  }
}

Health and upstream status:

curl 'https://chainrpc-mcp.mitander.io/health?upstream=1'

The hosted service is shared, rate-limited, and intentionally has both broadcast features disabled. It is suitable for evaluation and public-chain reads, but has no availability SLA. Requests are visible to the service operator and upstream RPC providers; use your own deployment for sensitive queries or production workloads.

Local stdio server

Requirements: Node.js 20 or newer.

npx -y chainrpc-mcp

Example client configuration:

{
  "mcpServers": {
    "chainrpc-mcp": {
      "command": "npx",
      "args": ["-y", "chainrpc-mcp"],
      "env": {
        "EVM_RPC_URL": "https://ethereum-rpc.publicnode.com",
        "BITCOIN_RPC_URL": "https://bitcoin-rpc.publicnode.com"
      }
    }
  }
}

The RPC variables are optional; they are shown to make the defaults explicit.

EVM

Tool	Purpose	State-changing
`evm_getBlockNumber`	Return the latest block number	No
`evm_getChainInfo`	Return chain ID and client version	No
`evm_getNativeBalance`	Read a native-token balance at a block	No
`evm_getBlock`	Read a block by number, tag, or hash	No
`evm_getTransaction`	Read a transaction and receipt	No
`evm_call`	Execute an `eth_call` with encoded calldata	No
`evm_readContract`	Encode, call, and decode a function from its ABI	No
`evm_estimateTransaction`	Estimate gas for an unsigned transaction	No
`evm_getLogs`	Query event logs with address and topic filters	No
`evm_broadcastTransaction`	Preflight and submit signed transaction bytes	Yes

Any HTTP(S) EVM JSON-RPC endpoint can be used, so the same tools work with Ethereum mainnet, testnets, and compatible chains. Results always come from the configured endpoint; callers should inspect evm_getChainInfo before making chain-specific assumptions.

Bitcoin

Tool	Purpose	State-changing
`btc_getBlockchainInfo`	Return network, height, sync, and pruning information	No
`btc_getAddressBalance`	Scan confirmed UTXOs for
