# 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](https://docs.coresignal.com/company-api/multi-source-company-api), [Multi-source Employee API](https://docs.coresignal.com/employee-api/multi-source-employee-api), and [Base Jobs API](https://docs.coresignal.com/jobs-api/base-jobs-api) 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
