Client Setup: Gemini CLI

Official references

Register

Install the release-candidate checkout on PATH as described in the root README, then register the stdio server:

gemini mcp add --scope user reasonkit-think reasonkit-think-mcp
gemini mcp list

The equivalent mcpServers entry is:

{
  "reasonkit-think": {
    "command": "reasonkit-think-mcp",
    "args": [],
    "trust": true
  }
}

The server emits Gemini-compatible tool schemas: optional parameters use an explicit type plus nullable: true. The default core pack exposes exactly 13 tools; use REASONKIT_TOOL_PACK=full only as the 47-tool compatibility escape hatch.

Verify

• gemini mcp list shows a connected local server.
• 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 Gemini CLI.
