What you can do with this MCP connector
This Clearbit (HubSpot) MCP Server plugs your B2B intelligence right into your AI agent. You'll use it to enrich person and company data using just an email or a domain name. You can audit leads, find company firmographics (like industry or size), find new prospects based on a tech stack, or calculate risk scores, all without leaving your chat interface.
If you only have a partial company name, you can use autocomplete_company to suggest potential company names and domains. To get a company's core details, you can run find_company using its domain name. You can find detailed professional info on a person using their email address with find_person. For combined details, find_person_and_company pulls both professional and company info from a single email.
You can calculate a specific risk score for any entity using find_risk. To find new potential leads, you can run get_prospects based on criteria like a watchlist or general search. You'll also get a curated list of companies you're tracking with get_watchlist and reveal an IP address for any domain name using reveal_ip.
How Clearbit (HubSpot) MCP Works
- 1 Subscribe to the server and input your Clearbit API Key from your dashboard.
- 2 Your AI client sends a request to the MCP Server, specifying the required data (e.g., an email or domain).
- 3 The server runs the necessary Clearbit API calls and returns structured B2B intelligence to your AI client.
The bottom line is you get structured B2B data directly in your chat window, letting your agent act on it immediately.
Who Is Clearbit (HubSpot) MCP For?
Anyone building pipelines around B2B intelligence. This is for the SDR who needs to verify a lead's job title instantly, the Marketing Manager automating lead segmentation without logging into a dashboard, or the Account Executive who needs a quick firmographic check during a call.
Verifies prospect company details and finds specific roles within a target account using natural language prompts.
Looks up stakeholder profiles and company firmographics instantly from the chat interface, keeping the conversation flowing.
Automates lead enrichment and audience segmentation by piping data directly into the AI agent, bypassing manual dashboard work.

Real-World Use Cases
Validating a Cold Lead's Role
A sales rep gets an email address for a prospect but needs to know their actual job title. They ask their agent to use find_person with the email. The agent immediately returns the name, job title, and social links, allowing the rep to tailor the opening line of an email.
Auditing a Target Company's Stability
The ops team needs to know if a potential partner is stable before committing resources. They instruct the agent to run find_risk against the company domain. The tool calculates the risk score, revealing potential financial or operational issues immediately.
Building a Segmented Prospect List
A marketing manager needs 50 companies running a specific tech stack (e.g., HubSpot). They ask the agent to use get_prospects with the tech stack criteria. The agent returns a clean list of domains and company names for bulk follow-up.
Getting Full Context on a Domain
An AE is in a call and needs to verify the size and industry of the company they are talking to. They ask the agent to use find_company with the domain. The agent provides the firmographics (industry, employees, location) instantly.
The Tradeoffs
Searching manually for data points
Opening a browser, navigating to a separate database, copying the domain, then pasting it into a CRM to check the industry.
→
Just tell your agent to use find_company with the domain. The agent returns the full firmographic data structure directly into your conversation.
Using general search engines for B2B data
Typing 'company info for X' into Google and wading through mixed results, news articles, and random Wikipedia entries.
→
Use find_person_and_company with the email address. This method pulls structured data from Clearbit, giving you validated job titles and company details, not just guesswork.
Assuming one tool covers everything
Thinking that just running find_person is enough, but missing the company size or industry context.
→
Combine tools by asking for combined enrichment. Use find_person_and_company to get both the person's role and the company's full logistics simultaneously.
When It Fits, When It Doesn't
Use this if you need to connect unstructured natural language queries to highly structured, validated B2B data. You need to know the who (person) and the what (company) with high confidence. The core requirement is moving from a vague idea ('We need to target finance companies') to a specific action ('Find companies in finance with 500-1000 employees').
Don't use this if your goal is simply general web search or content ideation. If you just need a quick definition or a general market overview, a standard LLM prompt is fine. But if you need reliable, actionable, and verifiable firmographic data, this is the right tool. It's for data-driven, high-stakes workflows.

Works with Claude, ChatGPT, Cursor, and more
The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.
This server provides 8 capabilities that interface natively with Claude, ChatGPT, Cursor, and any MCP client. No middleware. No custom integration required.
Available Capabilities
Manually compiling prospect data is a waste of time.
Today, when you get a list of names and emails, you open a spreadsheet. You manually copy the domain names into a separate tool, then look up the company size, then you search for the person's LinkedIn profile, and then you copy-paste all that info into a CRM record. It takes minutes per lead, and the data gets stale by the time you finish.
With the Clearbit (HubSpot) MCP Server, you just ask your agent. You give it the email or domain, and it runs the necessary enrichment tools (`find_person_and_company` or `find_company`) and spits out the complete, structured data set right in your chat. You get the full context, instantly.
Clearbit (HubSpot) MCP Server: Enrich data in the chat.
The tedious steps of opening the Clearbit dashboard, running the search, waiting for the page to load, and then copying the field data are eliminated. Your agent calls `find_risk` or `get_watchlist` directly through the conversation.
The whole process is now conversational. You tell the agent what you need—a risk score, a company size, or a list of prospects—and it handles the API calls and returns the final answer. It's that simple.
