MCP Server Overview

Comply exposes a Model Context Protocol (MCP) server so AI assistants can run compliance checks directly during a conversation.

What is the MCP server?

The MCP server wraps comply check as a tool that Claude Desktop, Cursor, and other MCP-compatible clients can call. When an AI assistant is reviewing code or helping with a pull request, it can invoke Comply to get structured feedback on the current diff.

The comply_check tool

The server exposes one tool:

Tool name: comply_check

Parameters:

Parameter	Type	Required	Description
repo_path	string	Yes	Absolute path to the git repository to check
config_path	string	No	Path to .comply.yml; defaults to <repo_path>/.comply.yml

Returns: JSON object with rule results

{
  "results": [
    {
      "rule": "no-print-statements",
      "status": "PASS",
      "message": "No print() calls found in diff"
    },
    {
      "rule": "has-test-coverage",
      "status": "FAIL",
      "message": "New functions added without corresponding tests"
    }
  ],
  "summary": {
    "passed": 8,
    "warned": 0,
    "failed": 1,
    "skipped": 0
  },
  "exit_code": 1
}
