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-mcpOr build from source to hack on it:
npm install && npm run buildUse 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.
