Api Key

Opencage is a geocoding service that turns addresses into coordinates and vice versa. It helps apps and agents get precise location data from open sources worldwide.

Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Opencage account to Claude via Composio Connect, enabling it to get coordinates for a hotel address, find the address of given GPS coordinates, return GeoJSON for a city location, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

Connecting Opencage to Claude Web, Desktop, and Cowork

Two ways to add the Composio connector. Pick whichever you prefer.

1. Add with one click

Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

Click Add custom connector and paste in the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
Add custom connector dialog with Composio MCP server URL

2. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

3. Connect your Opencage account

Back in Claude, ask it to connect to Opencage or give it any Opencage-related task.

For example, ask Claude to:

  • "Get coordinates for a hotel address"
  • "Find the address of given GPS coordinates"
  • "Return GeoJSON for a city location"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Opencage account is ready to use.

What is the Opencage Claude Connector, and what's possible with it?

The Opencage MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Opencage account. It provides structured and secure access to global geocoding services, so your agent can perform actions like translating addresses to coordinates, finding locations from GPS, converting to GeoJSON, and handling multiple output formats on your behalf.

  • Forward geocoding for addresses: Instantly convert human-readable addresses into precise latitude and longitude coordinates for mapping or logistics tasks.
  • Reverse geocoding coordinates: Give your agent raw GPS coordinates and receive the nearest human-readable address or location details.
  • GeoJSON feature generation: Request GeoJSON output for geocoding results, making it easy to visualize or integrate locations in mapping applications.
  • Flexible output formats: Get geocoding data in XML or JSONP formats, ensuring compatibility with a variety of development workflows and systems.
  • Seamless integration with open data sources: Tap into comprehensive and up-to-date location information sourced from open datasets for global coverage.

Troubleshooting

1. Why does Claude not use the Composio connector for Opencage?

The connector can show as connected, but Claude must use it in each Opencage conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Opencage again.

2. Why does Claude show an MCP server error before Opencage connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Opencage.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Opencage.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Opencage authorization link not work?

The Composio connector is one server. Your Opencage account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Opencage connection.
  • Composio creates a fresh Opencage authorization link.
  • Open that link in your browser and finish the Opencage sign-in.

4. Why do Opencage actions fail after they worked before?

The Opencage connection can expire or lose permission.

  • Ask Claude to inspect the Opencage connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Opencage account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Opencage.
  • If the action still fails with a permission error, check that the connected account has that permission in Opencage itself.

5. How do I switch to a different Opencage account?

Claude can manage the Opencage connection for you.

  • Ask Claude to disconnect or delete the current Opencage account.
  • Ask Claude to connect Opencage again.
  • Open the new Composio authorization link for Opencage.
  • Sign in with the other Opencage account in the browser.
  • After the account connects, ask Claude to retry the Opencage task.

6. Why is my Opencage connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Opencage connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Opencage tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Opencage.

FAQ

Frequently asked questions

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

Yes, you can. Claude Cowork 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 Opencage tools.

Yes, absolutely. You can configure which Opencage 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.

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 Opencage data and credentials are handled as safely as possible.
