Enables MCP clients to interact with over 31 blockchain chains through the MoltNode RPC gateway, providing tools for chain listing, RPC calls, block numbers, and native balance queries without API keys or setup.

moltnode-mcp

A Model Context Protocol server that gives any MCP client (Claude Desktop, Cursor, Cline, Windsurf, and friends) zero-config, no-key access to 31+ chains through the MoltNode RPC gateway. One URL per chain, for humans and agents.

The chain list is loaded live from https://moltnode.ag/api/chains at startup, so new chains appear automatically with no upgrade needed.

Tools

Tool	What it does
`list_chains`	Every reachable chain (slug, name, chainId, family, native currency).
`rpc_call`	Any JSON-RPC 2.0 call for EVM (`eth_*`), Solana, or Sui. The workhorse.
`get_block_number`	Latest block height / slot for a chain.
`get_balance`	Native balance of an EVM address (wei + decimal).

No API keys. No signup. Upstream failover is handled by the gateway.

Install

Published on npm, no clone needed:

npx -y moltnode-mcp

Or build from source to hack on it:

npm install && npm run build

Use it in an MCP client

Claude Desktop, in claude_desktop_config.json:

{
  "mcpServers": {
    "moltnode": {
      "command": "npx",
      "args": ["-y", "moltnode-mcp"]
    }
  }
}

Cursor / Cline / Windsurf use the same shape in their MCP settings. To run from a local build instead of npx:

{
  "mcpServers": {
    "moltnode": { "command": "node", "args": ["/absolute/path/to/moltnode-mcp/dist/index.js"] }
  }
}

Then ask your agent: "What's the latest block on Base?" or "ETH balance of 0xd8dA…6045 on Ethereum?" and it routes through MoltNode with no setup.

Config

Env var	Default	Purpose
`MOLTNODE_URL`	`https://moltnode.ag`	Point at a self-hosted gateway.
