## Introduction

Atomic Agent is an open-source AI agent that runs on your machine and supports local models through llama.cpp. Connect it to 1,500+ apps through Composio, including Opencage.
This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Opencage account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions.

## TL;DR

### How Atomic Agent connects to Opencage
Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication.
Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account.

## Connect Opencage to Atomic Agent

### Connect Opencage to Atomic Agent
- Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key.
- In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart.
- Ask Atomic Agent to do something in Opencage. It searches Composio for the right tool.
- On first use, open the sign-in link returned in the chat. Connect your Opencage account, then return to Atomic Agent to continue.
### Headless setup
Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file.

```bash
COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY
```

## What is the Opencage MCP server, 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.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `OPENCAGE_GEOCODE_FORWARD` | Forward Geocode Address | Tool to convert a human-readable address into geographic coordinates. Use when you need to retrieve latitude and longitude from an address. |
| `OPENCAGE_GEOCODE_GEOJSON` | Geocode to GeoJSON | Geocode addresses or coordinates and return results in GeoJSON FeatureCollection format. Use this tool when you need: - Geographic data in standard GeoJSON format for mapping applications - Forward geocoding: convert addresses to coordinates - Reverse geocoding: convert coordinates to addresses The response includes coordinates, formatted addresses, and optional annotations like timezone, currency, and sun times for each location. |
| `OPENCAGE_GEOCODE_GEOJSONP` | Geocode with JSONP | Geocode an address and return results wrapped in a JavaScript callback function (JSONP format). Use this tool when you need geocoding results that can be directly consumed by JavaScript through a callback function, typically for cross-domain AJAX requests in browser environments. The response wraps standard geocoding JSON with your specified callback function name. Example response: myCallback({"results":[{"geometry":{"lat":52.5,"lng":13.4},"formatted":"Berlin, Germany",...}],...}) |
| `OPENCAGE_GEOCODE_GOOGLE_V3_JSON` | Geocode Google v3 JSON | Tool to perform forward geocoding and return results in Google Geocoding API v3 compatible JSON format. Use when you need Google v3 compatible output for legacy integrations. Note: This is a legacy format that may be discontinued; using the standard JSON format is recommended. |
| `OPENCAGE_GEOCODE_REVERSE` | Reverse Geocode Coordinates | Tool to convert coordinates to a human-readable address. Use when you have latitude and longitude and need a readable location. |
| `OPENCAGE_GEOCODE_XML` | Geocode XML | Geocode a location query and return results in XML format. Supports both forward geocoding (address to coordinates) and reverse geocoding (coordinates to address). Use this when you need XML-formatted output instead of JSON. |
| `OPENCAGE_PING_OPENCAGE` | Check API Health | Tool to check API health and connectivity. Returns 'pong' if the API is reachable. Use when you need to verify that the OpenCage API is accessible and operational. |

## Troubleshooting

### Why is my API key rejected?

Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying.

### Why are Composio tools unavailable after saving a key?

Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk.

### Does Composio have a free plan?

The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection.

## Complete Code

## Conclusion

### Use Opencage from Atomic Agent
With your account connected, ask Atomic Agent to work with Opencage in natural language. You can connect more apps through the same Composio integration as you need them.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Opencage MCP?

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.

### Can I use Tool Router MCP with Atomic Agent?

Yes, you can. Atomic Agent 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.

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

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.

### 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 Opencage data and credentials are handled as safely as possible.
