🔗 MCP Link — Let AI Agents Use Your Tools

What is MCP Link?

MCP Link is a complete framework that enables AI agents such as ChatGPT, Claude, Gemini, and others to interact with the real world through a controlled, curated, safe browser- and server-based toolchain. It consists of a browser extension, an optional local MCP server, and a modular recipe and plugin system for AI integration and monetization.

How to use MCP Link?

Install the browser extension manually or via future web stores, then visit a supported AI site like chatgpt.com or claude.ai. The extension automatically discovers tools from a remote manifest; users can enable or disable tools per-tool and set runtime access policies (ask every time, allow automatically, or always allow). An optional local MCP server can be set up for advanced local tools.

Key features of MCP Link

• Recipe system that activates tool discovery on supported AI websites

Use cases of MCP Link

• Let ChatGPT rename a folder or modify files on your machine

FAQ from MCP Link

How does MCP Link keep tool use secure?

Every tool requires explicit user enablement, and calls can prompt for approval per use, be auto-allowed, or run in Docker sandboxing for isolation. All tool requests and responses are logged for audit.

Which AI models are supported?

ChatGPT, Claude, Gemini, Perplexity, and Grok are explicitly mentioned, with more AI sites planned via the recipe system.

Do I need to install a local server to use MCP Link?

No. Remote tools like geolocation, weather, and adaptive thinking work immediately without any local server. Installing the optional local MCP server adds more tools such as SQLite, TTS, and WhatsApp.

What transport protocol does the MCP server use?

The MCP server uses SSE (Server-Sent Events) for communication with the extension and AI agents.

Is the source code open source?

The source is visible for review but is proprietary; you cannot fork, copy, or reuse the code. Collaboration is welcome via Issues and Discussions.
