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, Multi-source Employee API, and 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 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.

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