Coresignal MCP with Claude: Faster Candidate Sourcing and Company Research
The short answer
Claude connects to Coresignal through the Model Context Protocol (MCP), a secure standard that lets Claude use the tool with permissions you control. Once connected, Claude can search public employee profiles, enrich company research and build candidate or lead lists from plain-English requests, while your team reviews and approves what happens next.
What is Coresignal?
Coresignal is a real-time public web data platform. It collects publicly available information about employees, companies and professional profiles, then makes that data searchable. HR and recruiting teams use it to find candidates and map talent pools. Research and market analysis teams use it to study workforce trends. Sales teams use it to build lead lists. It is designed to give teams fresh workforce data rather than outdated static records.
How Claude connects to Coresignal through MCP
The Model Context Protocol, or MCP, is an open standard that lets Claude securely use other software. Think of it as a universal adapter between Claude and a tool like Coresignal. Once the adapter is in place, you can ask Claude a question in ordinary language and it can carry out the lookup for you.
Once connected, Claude can read information from Coresignal, such as public employee profiles and company records, and use it to answer questions, summarise findings or prepare shortlists. Depending on how the connection is set up, it can also run structured searches and enrichment requests. Access is limited to what your organisation allows.
Permissions and approvals keep your people in charge. Access is granted with the API key your organisation controls, using the least access needed for the job. Sensitive or consequential actions, such as exporting lists or passing contact details to another system, can require a person to approve them first.
What you can automate
Candidate sourcing for open roles
A recruiter describes a role in plain English, such as a senior data engineer with cloud experience in Bangalore. Claude searches public profiles through Coresignal and returns a shortlist with relevant experience. The recruiter reviews the list and decides who to contact. This can shorten the first stage of sourcing considerably.
Talent market mapping
A talent acquisition lead wants to know where people with a specific skill set work and how the market is shifting. Claude gathers and summarises workforce data across companies and roles. The output helps leaders plan hiring budgets, choose locations and decide where to recruit next.
Company research before outreach
A business development manager preparing a meeting asks Claude for an overview of a target company, including its size, growth signals and key teams. Claude pulls enriched company information from Coresignal and produces a short briefing note. The manager walks into the meeting better prepared.
Sales lead list building
A sales operations team needs a list of companies in a particular sector and region with relevant decision-makers. Claude builds a draft list from Coresignal data, which a team member then checks against the ideal customer profile. Approved leads move into the CRM for follow-up.
Competitive hiring analysis
A people analytics team wants to compare hiring activity across competitors. Claude summarises public workforce signals for the companies named and highlights notable changes. The findings support workforce planning and compensation discussions, with analysts checking the conclusions before they are shared.

For teams in the US, UK, India and the Middle East
Organisations in the United States and the United Kingdom must consider their own employment, equal opportunity and data protection rules when sourcing candidates. In India, the Digital Personal Data Protection Act, 2023 applies to how personal data is handled. Organisations in the UAE and Saudi Arabia must follow their local data protection laws. We choose the hosting region for any custom application to help meet these requirements, but compliance remains your responsibility and should be confirmed with your legal advisers.

It acts as an adapter, so Claude can work with Coresignal without you having to write custom code for every search.
Is connecting Claude to Coresignal secure?
Security depends on how the connection is set up. We use the API key your organisation controls, grant only the access each role needs, and keep audit logs of activity. Sensitive actions such as exports can require approval. We also review data handling rules with you before launch.
What can Claude do with Coresignal once connected?
Typically, Claude can search public employee profiles, enrich company research, help source candidates and draft sales lead lists from plain-English requests. It can summarise what it finds. Actions that affect people or other systems can be set to require human approval first.
How long does setup take?
Timelines vary with the number of workflows and the systems involved. A focused single workflow is often set up within a few weeks, including testing and training. Larger workflows across several systems take longer. The free automation audit gives you a clearer estimate.
Which plan or permissions do I need?
