Sift MCP Server — Agent Execution Governance for Claude Desktop and other MCP clients

Sift MCP Server

Add Sift's agent execution governance to any Claude client (Claude Desktop, Claude Code, etc.)

What it does

Exposes 3 tools to Claude:

• sift_authorize -- get a signed authorization receipt before executing any real-world action
• sift_check_policy -- see what your agent is allowed to do
• sift_register_agent -- get onboarding instructions

Install

pip install mcp httpx cryptography

Add to Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (Mac) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "sift": {
      "command": "python",
      "args": ["C:/path/to/sift_mcp_server.py"]
    }
  }
}

Usage

Once installed, Claude will automatically have access to Sift's governance tools. Before any real-world action, Claude can call sift_authorize to get a signed receipt.
