Register

Install the release-candidate checkout on PATH as described in the root README, then add this entry to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "reasonkit-think": {
      "type": "stdio",
      "command": "reasonkit-think-mcp",
      "args": []
    }
  }
}

The default core pack exposes exactly 13 tools. Set REASONKIT_TOOL_PACK=full only as the 47-tool compatibility escape hatch.

Verify

• The MCP server appears as connected in Cursor's integrations view.
• Tool discovery returns exactly 13 tools under the default pack.
• The Auto → evidence → checkpoint/decision → audit path completes.

If startup reports an executable error, run command -v reasonkit-think-mcp in the environment that launches Cursor.
