killswitch-mcp 0.1.0

MCP server for killswitch-ai — scan LLM payloads, review findings, and inspect policy from Claude Desktop, Cursor, or any MCP client

killswitch-mcp

MCP server for killswitch-ai — give Claude Desktop, Cursor, or any MCP-capable client a live window into your egress guardrails.

Install

pip install killswitch-mcp

This installs killswitch-ai and mcp automatically.

Start the server

killswitch-mcp

The server speaks MCP over stdio and waits for a client to connect.

Client configuration

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows), then restart Claude Desktop:

{
  "mcpServers": {
    "killswitch": {
      "command": "killswitch-mcp"
    }
  }
}

Cursor

Open Settings → Cursor Settings → MCP, click Add new global MCP server, and paste:

{
  "mcpServers": {
    "killswitch": {
      "command": "killswitch-mcp"
    }
  }
}

Tools

Tool	Description
scan	Pre-flight scan text before sending to an LLM — returns findings metadata, never echoes input
get_status	Current enforcement mode and headline event counts
get_stats	Full aggregate stats from the local audit database
recent_findings	Recent audit findings with type, severity, and decision
get_policy	Active killswitch.yml policy (credentials stripped)

All tools are read-only. None write to disk or affect any running killswitch.install() session.

Important

The MCP server is a voluntary, opt-in guardrail. For automatic inline enforcement that intercepts every LLM call regardless of what an agent requests, use killswitch.install() in your Python process.
