tuantqse90/moltnode-mcp

Read 31 blockchains and swap tokens from any AI agent. One hosted MCP server, no API key, no signup.
Read: JSON-RPC on Ethereum, Base, Arbitrum, Solana, Monad, BNB Chain, Avalanche, Sui and 23 more, through MoltNode (automatic failover across providers).
Trade: best-route swap quotes from Chord on Ethereum, Base, Monad, BNB Chain, Avalanche, Arbitrum, Robinhood Chain and Arc, with the unsigned transaction, the approval it needs and a simulation run from your wallet. Your agent signs with its own key; nothing is ever held for you.

## Connect
Claude Code
bash
claude mcp add --transport http moltnode https://moltnode.ag/mcp
Or install everything as a plugin (MoltNode + Chord MCP servers and the three skills):
/plugin install moltnode --marketplace tuantqse90/moltnode-mcp
Cursor, Windsurf, VS Code, Claude Desktop and any client that takes a URL
json
"mcpServers": {
"moltnode": { "type": "http", "url": "https://moltnode.ag/mcp" }
In Claude Desktop or claude.ai you can also add it under Settings → Connectors → Add custom connector, with the URL above.
Clients that only start local commands (stdio)
json
"mcpServers": {
"moltnode": { "command": "npx", "args": ["-y", "moltnode-mcp"] }
(npx -y github:tuantqse90/moltnode-mcp works too.)
The stdio bridge in this repo (index.mjs) forwards every call to the hosted server, so both give the same tools. Without network it still lists the tools (from tools.json, a snapshot of the hosted list refreshed with npm run refresh-tools) and each call says the server is unreachable.
## Tools
| Tool | What it does |
| listchains | Every chain MoltNode serves (slug, chainId, native coin, endpoint) and the ones Chord trades on |
| rpccall | Any JSON-RPC method on any chain: ethcall, ethgetLogs, Solana getBalance, Sui methods, … |
| getblocknumber | Latest block of an EVM chain |
| getbalance | Native-coin balance of an address on an EVM chain |
| chordfindtoken | Token address, decimals and verified flag by symbol or name |
| chordswapquote | Best route across the chain's DEXs + unsigned tx + approval (as a ready transaction) + simulation from the taker wallet |
| sendrawtransaction | Broadcast a signed transaction |
## How an agent swaps
1. chordfindtoken → the addresses and decimals of the two tokens (the zero address is the native coin).
2. chordswapquote with taker = the agent's wallet. Amounts are integer strings in the token's smallest unit (10000000 = 10 USDC).
3. If the answer has approval, sign and send approval.tx first.
4. Sign tx with the agent's own key.
5. sendrawtransaction on the same chain.
The router enforces minAmountOut on-chain. Chord's own router answers first; another aggregator is used only when Chord has no route, and the answer says which.
## Agent skills
Install with the skills CLI (Claude Code, Codex, Cursor, Gemini CLI and more): npx skills add tuantqse90/moltnode-mcp, or in Hermes: hermes skills tap add tuantqse90/moltnode-mcp. Gemini CLI extension: gemini extensions install https://github.com/tuantqse90/moltnode-mcp.
skills/moltnode/: read 31 chains and swap through Chord end to end, with the safety rules (never handle a private key, confirm the quote before signing).
