Introduction

Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Foursquare MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer.

Why use Composio?

Apart from a managed and hosted MCP server, you will get:

  • CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
  • Large tool responses: Handle them to minimise context rot.
  • Dynamic just-in-time access to 20,000 tools across 870+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need.

How to install Foursquare MCP in Codex

Run the setup command

Run this command in your terminal to add the Composio MCP server to Codex.

Terminal

It will initiate the authentication in a browser window, authorize Codex to access your Composio account.

Composio authentication page

(Optional) Authenticate with OAuth

To authenticate manually, run the login command to open a browser window and authorize Codex to access your Composio account.

bash
codex mcp login composio

Verify the connection

Run codex mcp list to confirm Composio appears as a registered MCP server.

bash
codex mcp list

Codex App

Codex App follows the same approach as VS Code.

  1. Click ⚙️ on the bottom left → MCP Servers → + Add servers → Streamable HTTP:
  2. Fill the header and Key fields with { "x-consumer-api-key" = "ck_*******" }.
  3. The Key is the Composio API key, that you can find on connect.composio.dev
  4. Click on Authenticate and authorize Codex to your Composio account and you're all set.
Codex App MCP setup
  1. Restart and verify if it's there in .codex/config.toml
bash
[mcp_servers.composio]
url = "https://connect.composio.dev/mcp"
http_headers = { "x-consumer-api-key" = "ck_*******" }

What is the Foursquare MCP server, and what's possible with it?

The Foursquare MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Foursquare account. It provides structured and secure access to the powerful Foursquare Places database, so your agent can search for venues, recommend places, retrieve detailed location data, surface user tips, and even fetch photos—all on your behalf.

  • Comprehensive place search and discovery: Let your agent find places or points of interest nearby or in any area using keywords, categories, or specific criteria.
  • Retrieve rich place details: Instantly pull in-depth information about a specific venue, including its name, address, ratings, categories, and more.
  • Access user-generated tips and reviews: Have your agent surface real user insights, tips, and experiences for any place to help guide your decisions.
  • Fetch location photos: Enhance your applications by retrieving and displaying user-contributed images for any venue in the Foursquare database.
  • Explore lesser-known and trending spots: Use Foursquare's broader search to discover new, up-and-coming, or hidden places that might not appear in standard searches.

Supported Tools & Triggers

Tools
Retrieve nearby places v3The getnearbyplaces endpoint retrieves a list of places near a specified location, primarily supporting check-in use cases and local discovery.
Retrieve place photos by idRetrieves photos associated with a specific place in foursquare's database.
Retrieve places by idRetrieves detailed information about a specific place using its unique foursquare id (fsq id).
Retrieve place tips using fsq idRetrieves user-generated tips for a specific place in the foursquare database.
Search places api requestThe getplacessearch endpoint allows you to search for places in the foursquare database based on various criteria such as location, keywords, and categories.

Conclusion

You've successfully integrated Foursquare with Codex using Composio's MCP server. Now you can interact with Foursquare directly from your terminal, VS Code, or the Codex App using natural language commands.

Key benefits of this setup:

  • Seamless integration across CLI, VS Code, and standalone app
  • Natural language commands for Foursquare operations
  • Managed authentication through Composio
  • Access to 20,000+ tools across 870+ apps for cross-app workflows
  • CodeAct workbench for complex tool chaining

Next steps:

  • Try asking Codex to perform various Foursquare operations
  • Explore cross-app workflows by connecting more toolkits
  • Build automation scripts that leverage Codex's AI capabilities

FAQ

What are the differences in Tool Router MCP and Foursquare MCP?

With a standalone Foursquare MCP server, the agents and LLMs can only access a fixed set of Foursquare tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Foursquare and many other apps based on the task at hand, all through a single MCP endpoint.

Can I use Tool Router MCP with Codex?

Yes, you can. Codex fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Foursquare tools.

Can I manage the permissions and scopes for Foursquare while using Tool Router?

Yes, absolutely. You can configure which Foursquare scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Foursquare data and credentials are handled as safely as possible.
