Coresignal MCP: Top-quality B2B data for AI agents
The MCP with OAuth connects multi-source company, employee, and jobs data directly to an agent or any MCP-ready platform without exposing an API key.
Multi-source Company API
Company firmographics, financials, funding, workforce, online presence, technographics, reviews, and more. 500+ data points in each record.
Multi-source Employee API
A full, up-to-date picture of someone's professional experience, qualifications, and professional activity. 250+ data points in each record.
Jobs API
Active job postings from a database updated in real time, and years of historical job posting data.
Four tools, one clean workflow
The new MCP splits the tool into four, each with a specific job.
Search and download data
The new MCP with OAuth also allows downloading data. Enabling downloads from third-party tools isn't universal: check each tool's documentation to see how to configure the necessary permissions.
The API key never touches the client
With OAuth 2.1 your data key is fetched live with every request and never stored, so you can revoke access instantly.
The key stays on the server
The key remains securely on Coresignal's server, and you only receive a short-lived credential.
Simple setup
Connecting an agent to Coresignal's data is as straightforward as logging into any SaaS product. You can grant, revoke, or rotate access directly from a central dashboard.
Reduced security risk
OAuth maintains the data API key server-side, which keeps sensitive information from your device.
