About LexPact UK Contracts

LexPact UK Contracts is an MCP server that exposes LexPact’s UK-law contract generation API to Claude Desktop and other MCP clients. It provides tools to browse templates, generate contracts and retrieve them, while API-side validation and generation remain on LexPact’s service.

MCP support

Exposes LexPact’s API to MCP clients through `list_contract_templates`, `generate_contract` and `get_contract` tools. An API key is required.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

From the project README

LexPact MCP Server

Exposes the LexPact contract generation API to Claude Desktop (or any MCP client) as three tools: list_contract_templates, generate_contract, get_contract. Thin proxy only — all validation and generation happens server-side at https://lexpact.co.uk/api/v1, so structured, LLM-actionable error messages reach Claude unchanged.

Setup

  1. Get an API key at lexpact.co.uk/dashboard/api-keys.
  2. Install dependencies: 
    cd mcp-server
npm install
  3. Add to your Claude Desktop config (claude_desktop_config.json — Settings → Developer → Edit Config): 
    {
  "mcpServers": {
    "lexpact": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-server/index.js"],
      "env": {
        "LEXPACT_API_KEY": "lp_live_your_key_here"
      }
    }
  }
}
  4. Restart Claude Desktop. Ask it to draft a contract — it will call list_contract_templates and generate_contract as needed.

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
