Today, we're introducing a new feature that unlocks new opportunities for companies building or using advanced AI solutions: our new MCP (Model Context Protocol) server that connects Coresignal's data directly with LLM-powered applications.
Currently, the Coresignal MCP server lets you interact with the Multi-Source Company API, the Multi-Source Employee API, and the Base Jobs API, giving your applications and models access to millions of comprehensive and fresh data records.
What is an MCP server?
An MCP server acts as a central hub that connects AI models and applications to data. Instead of hardcoding data sources into each model, the Model Context Protocol allows models to dynamically request and receive the right data through the MCP server.
This setup keeps data access flexible, secure, and easier to manage. It is similar to giving AI models a smart assistant that always knows where to find the most relevant information in a particular data source. In this case, Coresignal’s database.
Coresignal MCP: How it works
The MCP connection provides the AI application with structured access to our APIs. The retrieved data flows back through the MCP connection, becoming available as context for the LLM to reference, analyze, and incorporate into its outputs without leaving the user's workflow.
The MCP server bridges our data APIs and AI systems, allowing LLMs to directly access, query, and analyze our data without requiring custom connectors or complex integration work. Users can now have their LLM tools pull relevant data, build AI agents, perform analysis, and generate insights using our rich data through natural language requests.
How can I access it?
- Connect to our MCP server directly at https://mcp.coresignal.com/sse
- If you're already using Coresignal's API, you can access Coresignal MCP server using your existing API credentials. In the configuration, include your API key as the value <api_key>. No separate authentication method or additional purchases are required.
Credits for requests performed through the MCP server will also be deducted from the same credit balance.

Getting started
As mentioned above, you can get started immediately using your existing Coresignal account and API key. For more details, contact your account manager or book a free consultation with our data strategy consultants.
Why should you use it?
A seamless integration created by the MCP server eliminates the typical technical complexity and the need for many development resources required for building custom integration solutions. You can get value from large-scale, comprehensive public web data about companies, professionals, and the job market.
Multi-Source Company API
The Multi-Source Company API provides enriched company records and unmatched comprehensiveness, combining over 500 data points from multiple categories and AI-powered insights into each record, which makes it an invaluable resource as an MCP for company data.
Multi-Source Employee API
The Multi-Source Employee API unlocks access to detailed data on professionals. Each record combines over 250 data points and shows a complete view of qualifications, their past and current work experience, and professional activity.
Base Jobs API
Jobs API gives you access to an extensive jobs database, which is updated daily. The jobs database also includes years of historical data, which is hard to find and exceptionally useful for market research and deeper insights.
