How to integrate Placekey MCP with Atomic Agent

Connect Atomic Agent to Placekey MCP. Find placekey for this street address, get latitude and longitude from an address, and more using natural language, with authentication handled for you.

Api Key

Placekey standardizes and unifies location data by assigning unique IDs to addresses. It simplifies address matching and enables seamless data sharing across platforms.

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 Placekey.

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 Placekey account. See the Atomic Agent documentation for installation instructions.

How Atomic Agent connects to Placekey

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 Placekey to Atomic Agent

  1. Sign up or sign in to the Composio dashboard. Copy your API key.
  2. 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.
  3. Ask Atomic Agent to do something in Placekey. It searches Composio for the right tool.
  4. On first use, open the sign-in link returned in the chat. Connect your Placekey 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 Placekey MCP server, and what's possible with it?

The Placekey MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Placekey account. It provides structured and secure access to location standardization tools, so your agent can perform actions like converting addresses to Placekeys, retrieving geocodes, and mapping locations on your behalf.

  • Address to Placekey conversion: Instantly convert any physical address into a unique Placekey identifier for seamless data matching and enrichment.
  • Geocode retrieval from address: Have your agent fetch latitude, longitude, and full geocode details for any address, complete with Placekey and location info.
  • Placekey generation from coordinates: Quickly generate a Placekey for any geographic coordinates, making it easy to standardize and deduplicate location data.
  • Location deduplication and validation: Let your agent use Placekeys to match, validate, and deduplicate different representations of the same physical place across your datasets.

Use Placekey from Atomic Agent

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

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 for the current limits that apply to your connection.

FAQ

Frequently asked questions

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

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 Placekey tools.

Yes, absolutely. You can configure which Placekey 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 Placekey data and credentials are handled as safely as possible.
