## 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 Coresignal.
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 Coresignal account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions.

## Also integrate Coresignal with

- [ChatGPT](https://composio.dev/toolkits/coresignal/framework/chatgpt)

- [Hermes](https://composio.dev/toolkits/coresignal/framework/hermes-agent)

## TL;DR

### How Atomic Agent connects to Coresignal
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 Coresignal to Atomic Agent

### Connect Coresignal 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 Coresignal. It searches Composio for the right tool.
- On first use, open the sign-in link returned in the chat. Connect your Coresignal 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 Coresignal MCP server, and what's possible with it?

The Coresignal MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Coresignal account. It provides structured and secure access so your agent can perform Coresignal operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CORESIGNAL_GET_REAL_TIME_EMPLOYEE_PROFILE` | Get Real-Time Employee Profile | Retrieve an employee profile, using cached data up to max_age hours old (24 by default); set max_age=0 to request current data. Requires the connected account's separate Real-time Employee API entitlement and may take up to 30 seconds. |
| `CORESIGNAL_SEARCH_FAST` | Fast Search | Turn a natural-language employee, company, or job search into an Elasticsearch query, or return matching preview records. Prefer this lower-cost search unless deeper reasoning or clarification is needed; each call consumes Coresignal credits. |
| `CORESIGNAL_SEARCH_WITH_REASONING` | Search With Reasoning | Run a higher-cost natural-language search that explains its interpretation and can request clarification. Use when fast search is ambiguous or reasoning is valuable; a query-mode call consumed 100 trial credits in testing, data-mode cost varies, clarification requests do not consume credits, and the endpoint is limited to 10 requests per hour. |

## Supported Triggers

None listed.

## 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 Coresignal from Atomic Agent
With your account connected, ask Atomic Agent to work with Coresignal 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 Coresignal MCP?

With a standalone Coresignal MCP server, the agents and LLMs can only access a fixed set of Coresignal tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Coresignal 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 Coresignal tools.

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

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