On Windows? The per-client links below go to the macOS guides. Everything on this page applies to both, but the step-by-step for Windows — install, connect your client, first tool call, and what is not supported yet — lives in Install LMCP on Windows.

Desktop apps — automatic

These are detected and configured when you install LMCP; just restart the app once: Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed.

Claude Desktop — tools appear under the 🔨 icon.
Cursor — tools only show in Agent mode (⌘I → mode selector).
VS Code — Copilot chat in Agent mode, MCP enabled in settings.

Web AIs — Cloud Relay

ChatGPT, Claude.ai, Grok and Perplexity run in the cloud and can’t reach localhost. The opt-in Cloud Relay creates an encrypted tunnel from your computer so they can call your tools. Requested results pass through the relay to the AI provider under the applicable data policies. Enable it in the LMCP app (Your web AI · Cloud Relay) — the menu bar on Mac, the system tray on Windows — then follow the per-client guide:

More than one machine? The connector answers as the machine you approve on. To connect another machine, open the approval page in a browser on that machine and approve there: approving from the first machine’s browser always connects the first one. To use two machines from one AI app, the route today is Agent Mesh. Whether one AI app can hold two connector entries with the same URL depends on the app and is not promised.

Any other MCP client — manual

Add a stdio MCP server with the command npx -y local-mcp@latest — a thin proxy that connects to the LMCP app running on your computer:

Raycast — “Manage MCP Servers” command.
Warp — Settings → AI → Manage MCP servers.
Anything else that speaks MCP: same command.

Verify it works

Ask your AI: “What’s on my calendar today?” If tools don’t appear, restart the AI client once and check Troubleshooting.
