Skill

Install the companion skill to give Claude built-in knowledge of GroupMe workflows — group name resolution, message pagination, the async add_members flow, and more — without needing to prompt it each time.

The skill folder lives at skill/groupme-mcp/.

Install in Claude.ai: Settings → Capabilities → Skills → Upload skill → select the skill/groupme-mcp/ folder (zipped).

Install in Claude Code: place the skill/groupme-mcp/ folder in your Claude Code skills directory.

Requirements

• Python 3.12+
• A GroupMe access token — get one at dev.groupme.com or use the OAuth helper

Usage

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "groupme": {
      "command": "uvx",
      "args": ["groupme-mcp"],
      "env": {
        "GROUPME_TOKEN": "<your-token>"
      }
    }
  }
}

Local development

git clone https://github.com/KalebJS/groupme-mcp
cd groupme-mcp
export GROUPME_TOKEN=<your-token>
uv run mcp dev main.py   # opens MCP Inspector in browser

Getting a Token

oauth/get_token.py runs a local OAuth flow using only the Python stdlib — no extra dependencies.

1. Create an application at dev.groupme.com/applications.
2. Set the callback URL to http://localhost:8080/callback.
3. Run the helper:

python oauth/get_token.py --client-id YOUR_CLIENT_ID

The script opens your browser, waits for the GroupMe redirect, and prints the token along with the export command to set it.
