The LI.FI Intents MCP Server integrates with the LI.FI Intents API to provide cross-chain escrow order management and solver operations via the Model Context Protocol (MCP). Built for solver operators — replaces the manual Lintent.org UI workflow with programmatic access to quote management, order lifecycle, and route diagnostics.
Unlike the general LI.FI MCP server (read-only quotes and routing), this server performs write operations — it submits signed orders, registers solvers, and manages standing quotes. The hosted server never holds private keys.

​
Quickstart

Add the hosted LI.FI Intents MCP server to your AI tool. No installation required: 
{
  "mcpServers": {
    "lifi-intents": {
      "type": "http",
      "url": "https://intents-mcp.li.fi/mcp",
      "headers": {
        "x-api-key": "your-solver-api-key"
      }
    }
  }
}
Paste this into your MCP client config and start querying intents data. See Installation for tool-specific setup instructions. The x-api-key header is only required for solver tooling. If you have a Solver API key, set it as x-api-key in headers; otherwise remove the field.

​
How It Works

The MCP server wraps the LI.FI Intents REST API into MCP-compatible tools that AI agents can call directly. Instead of constructing HTTP requests, your AI tool discovers and invokes structured tools like request-quote, prepare-order, and submit-standing-quotes.

Example Workflow

A typical cross-chain swap via the MCP server follows this flow: 
1. get-supported-routes          # Discover available chain + token pairs
2. request-quote                 # Get pricing (chain names, symbols, or IDs all work)
3. prepare-order                 # Build order structure (unsigned)
4. (external) Sign the order using EIP-712 typed data signing
5. submit-order                  # Submit signed order to the order server
6. track-order                   # Monitor: Submitted -> Open -> Signed -> Delivered -> Settled

​
API Key Configuration

Without an API key, only integrator tools are available (read-only operations). With an API key, solver tools are also enabled, including submit-standing-quotes, debug-order, and check-route-health.
  1. Go to intents.li.fi (mainnet) or devintents.li.fi (testnet)
  2. Connect your wallet and register as a solver
  3. Copy your API key from the dashboard
  4. Add it in "headers" as x-api-key in your MCP config
