Features

All responses include a _meta block with transparency info (completeness, API calls made, data scope) to help AI models make informed decisions about expensive operations.

Tool Costs

Example _meta Response

Every tool response includes metadata like this:

{
  "_meta": {
    "is_complete": true,
    "returned_count": 50,
    "total_available": 1847,
    "limit_applied": 50,
    "api_calls_made": 1,
    "data_source": "foursquare_swarm_api",
    "data_scope": "authenticated_user_checkins"
  },
  "checkins": [...]
}

Installation

Using uvx (recommended)

uvx swarm-mcp

Using pip

pip install swarm-mcp

Setup

1. Get Your Foursquare Access Token

You'll need a Foursquare OAuth2 access token:

1. Go to Foursquare Developer Apps
2. Create a new app (or use an existing one)
3. Note your Client ID and Client Secret
4. Generate an access token using the OAuth2 flow, or use the API Explorer to get a token quickly

Security: Treat FOURSQUARE_TOKEN like a password—don't commit it, paste it in issues, or share screenshots with it visible.

2. Configure Your MCP Client

Claude Desktop

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "swarm": {
      "command": "uvx",
      "args": ["swarm-mcp"],
      "env": {
        "FOURSQUARE_TOKEN": "your-access-token-here"
      }
    }
  }
}

Claude Code

claude mcp add swarm uvx swarm-mcp -e FOURSQUARE_TOKEN=your-access-token-here

Or add manually to your config:

{
  "Swarm": {
    "command": "uvx",
    "args": ["swarm-mcp"],
    "env": {
      "FOURSQUARE_TOKEN": "your-access-token-here"
    }
  }
}

Usage Examples

Once configured, you can ask Claude things like:

• "Show me my recent Swarm check-ins"
• "How many times have I checked into coffee shops this year?"
• "What are my top 10 most visited coffee shops?"
• "Show me all my check-ins in California"
• "What are my check-in stats?"
• "Get details about [venue name]" (ratings, hours, tips)
• "What are the ratings for my favorite restaurants?"
