Add MCP Server to ChatGPT & Claude (Desktop)

Prereq: Install PromptBin first (pip install promptbin). The apps will launch the MCP server themselves.

ChatGPT Desktop (Mac/Windows):

• Open Settings → Developer → Model Context Protocol.

• Click "Add Server".

• Name: PromptBin

• Command: uvx

• Args: promptbin

Claude Desktop (Mac/Windows):

• Open Settings → Developer → Edit Config

"PromptBin": {
            "command": "uvx",
            "args": ["promptbin"]
        }

Notes:

• After adding, you can list/search prompts via the PromptBin MCP tools. The MCP server also starts the local web UI on http://127.0.0.1:<port>.

• If uvx is not available, ensure you have uv installed and use pip install promptbin instead.
