Grove starts its local MCP server at:

http://127.0.0.1:52718/mcp

Grove is independent and is not affiliated with or endorsed by Apple.

Agent setup

On first launch, Grove finds supported agents and offers their setup action. Grove currently checks for Codex, Claude Code, Hermes, OpenClaw, Cursor, and Windsurf.

For other clients, add the endpoint using the client’s MCP settings.

Hermes

Add this to the Hermes MCP configuration:

mcp_servers:
  grove:
    url: http://127.0.0.1:52718/mcp

Reload MCP servers in Hermes after saving the file.

OpenClaw

openclaw mcp set grove '{"url":"http://127.0.0.1:52718/mcp","transport":"streamable-http"}'

Grove agent skill

Grove installs its skill for supported agents when it starts. It writes to ~/.agents/skills/grove, ~/.codex/skills/grove, and ~/.claude/skills/grove.

If it is not installed, run:

npx skills add https://github.com/thsnkhn/grove/tree/main/skills/grove --global

Restart the agent after installation. See AGENTS.md for technical details and stdio setup.
