Intents MCP Server

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:

get-supported-routes          # Discover available chain + token pairs
request-quote                 # Get pricing (chain names, symbols, or IDs all work)
prepare-order                 # Build order structure (unsigned)
(external) Sign the order using EIP-712 typed data signing
submit-order                  # Submit signed order to the order server
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.

Go to intents.li.fi (mainnet) or devintents.li.fi (testnet)
Connect your wallet and register as a solver
Copy your API key from the dashboard
Add it in "headers" as x-api-key in your MCP config
