@traderouter/trade-router-mcp

A Model Context Protocol server for TradeRouter.ai — non-custodial Solana swap, limit, trailing, DCA, TWAP, and combo-order engine for AI agents.

Is this safe?

Yes, and here's exactly why. The private key is read once from TRADEROUTER_PRIVATE_KEY, used for local signing with @solana/web3.js + tweetnacl, and never transmitted, logged, or persisted. Only signed transactions leave your machine. Server messages are Ed25519-verified against a hard-coded trust anchor. See SECURITY.md for the full threat model, data-flow diagram, and permissions manifest.

Signing flow:

1. Agent calls build_swap → MCP sends wallet address (public key) to api.traderouter.ai
2. API returns an unsigned transaction
3. MCP signs the tx locally using TRADEROUTER_PRIVATE_KEY
4. The signed transaction is submitted to /protect (Jito MEV-protected bundle)
5. Server confirms and returns balance changes. The private key never crosses the network.

Requirements

• Node.js ≥ 18
• A Solana wallet private key in base58 format (use a dedicated trading wallet, not your main holdings)

Install

npx -y @traderouter/trade-router-mcp

Or wire it into an MCP client (Claude Desktop, Cursor, Cline, etc.):

{
  "mcpServers": {
    "traderouter": {
      "command": "npx",
      "args": ["-y", "@traderouter/trade-router-mcp"],
      "env": {
        "TRADEROUTER_PRIVATE_KEY": "your_base58_private_key"
      }
    }
  }
}

| OS | Claude Desktop config path | |---------|---------------------------------------------------------------------| | macOS | ~/Library/Application Support/Claude/claude_desktop_config.json | | Windows | %APPDATA%\Claude\claude_desktop_config.json | | Linux | ~/.config/Claude/claude_desktop_config.json |

Environment variables

| Variable | Required | Default | Purpose | |---|---|---|---| | TRADEROUTER_PRIVATE_KEY | ✅ | — | Solana wallet private key (base58). Local use only. | | SOLANA_RPC_URL | ❌ | https://api.mainnet-beta.solana.com | Custom RPC for reads | | TRADEROUTER_SERVER_PUBKEY | ❌ | baked-in trust anchor | Override the server's Ed25519 trust anchor | | TRADEROUTER_SERVER_PUBKEY_NEXT | ❌ | (unset) | Accept messages signed by this key in addition to the primary (key rotation) | | TRADEROUTER_REQUIRE_SERVER_SIGNATURE | ❌ | true | Verify server signatures on order_filled / twap_execution | | TRADEROUTER_REQUIRE_ORDER_CREATED_SIGNATURE | ❌ | true | Verify server signatures on order_created | | TRADEROUTER_DRY_RUN | ❌ | false | When true, every write-action tool (submit_signed_swap, auto_swap, place_*_order, cancel_order, extend_order) returns { dry_run: true, tool, args } instead of calling the API. Read-only tools execute normally. Added in 1.0.9. |

Tools

| Tool | Purpose | |---|---| | get_wallet_address | Get the configured wallet's public address | | build_swap | Build an unsigned swap transaction | | submit_signed_swap | Submit a manually signed transaction | | auto_swap | Build + sign + submit in one call | | get_holdings | Get token holdings for a wallet | | get_mcap | Market cap and price for a token | | get_flex_card | Trade card PNG URL for wallet + token | | place_limit_order | Limit buy/sell by price or market cap | | place_trailing_order | Trailing stop buy/sell | | place_twap_order | TWAP (time-weighted) buy/sell | | place_limit_twap_order | Limit trigger → TWAP execution | | place_trailing_twap_order | Trailing trigger → TWAP execution | | place_limit_trailing_order | Limit trigger → trailing execution (single swap on trigger) | | place_limit_trailing_twap_order | Limit trigger → trailing trigger → TWAP execution | | list_orders | List active orders for a wallet | | check_order | Get status of a specific order | | cancel_order | Cancel an active order | | extend_order | Extend an order's expiry | | connect_websocket | Register a wallet over the persistent WebSocket | | connection_status | Current WebSocket connection state | | get_fill_log | Log of filled orders |

REST endpoints (under the hood)

| Endpoint | Purpose | |---|---| | POST /swap | Build unsigned swap (multi-DEX: Raydium, PumpSwap, Orca, Meteora) | | POST /protect | Submit signed tx via Jito bundle — MEV-protected | | POST /holdings | Wallet scan — catches tokens standard RPC misses | | GET /mcap | Market cap + price | | GET /flex | Trade card PNG generation | | wss://api.traderouter.ai/ws | Persistent WebSocket for limits / trailing / DCA / TWAP / combo orders |

Trust anchor

The baked-in server public key is EXX3nRzfDUvbjZSmxFzHDdiSYeGVP1EGr77iziFZ4Jd4. Every order_filled, order_created, and twap_execution message from the server is verified with Ed25519 before being treated as authoritative. See SECURITY.md for details and the rotation mechanism (TRADEROUTER_SERVER_PUBKEY_NEXT).

Use with LangChain

Any MCP server works in LangChain via the official adapter:

from langchain_mcp_adapters.client import MultiServerMCPClient

client = MultiServerMCPClient({
    "traderouter": {
        "command": "npx",
        "args": ["-y", "@traderouter/trade-router-mcp"],
        "transport": "stdio",
        "env": {"TRADEROUTER_PRIVATE_KEY": "<base58>"},
    },
})
tools = await client.get_tools()

Fees

Flat 1% fee on swap volume, embedded in routing at /protect. No subscription, no API key, no monthly minimums. Read-only endpoints (/holdings, /mcap) are free.
