# Coresignal MCP

**Coresignal MCP** is a server that connects Coresignal's data directly with LLM-powered applications and allows AI assistants to tap into Coresignal’s data. By integrating it with Claude, Cursor, and other MCP-compatible AI assistant tools, you can access the latest [Multi-source Company API](/company-api/multi-source-company-api.md), [Multi-source Employee API](/employee-api/multi-source-employee-api.md), and [Base Jobs API](/jobs-api/base-jobs-api.md) information directly within chat interfaces.

## Prerequisites

To connect to the remote Coresignal MCP server using `mcp-remote` you need to have [Node.js](https://nodejs.org/en/download) installed.

Credits for requests performed through the MCP server will also be deducted from the same credit balance.

## Integration with AI assistants

Learn integration steps for a few AI assistant tools.

{% hint style="warning" %}
Enter your API Key as the `<api_key>` value. Get your key from Coresignal's [self-service platform](https://dashboard.coresignal.com/sign-in).

Do not forget to refresh the tool after the integration steps.
