## Description

This MCP lets your AI client pull deep background intel on prospects without leaving the chat window. Instead of opening ten different tabs or manually entering domains into a dashboard, your agent handles it all through natural language conversation. You can feed in a single email address and get details on the person—like their job title and social profiles—and simultaneously get data on the company they work for, like its industry or employee count. Need to find new targets? You can even search for companies based on criteria such as technology stack or revenue bracket.

Because you're dealing with sensitive B2B credentials, we run everything through Vinkius’s zero-trust proxy. This means your API keys pass securely in transit; they never sit on a disk. It keeps the data clean and focused entirely on actionable intelligence. You can use this MCP to enrich entire lists of contacts or audit existing accounts just by asking your agent what you need.

## Capabilities

### Enriching profiles from email
Finds a person's detailed job history, social links, and their associated company data using just an email address.

### Profiling companies by domain
Retrieves firmographic details, such as the industry, size, and location of a business using only its website domain name.

### Discovering new target accounts
Searches for businesses that match specific criteria you set, like having a certain technology stack or generating minimum revenue.

### Calculating prospect risk scores
Runs data through specialized checks to calculate an immediate risk score associated with a given contact or company.

### Getting account visibility details
Pulls core account and quota information directly from your connected workspace into the chat.

## Use Cases

### Cold calling a new prospect
You have an email address but no idea if the person is a decision-maker. You ask your agent to run `find_person`, which confirms they are a Director and provides links to their social profiles, letting you tailor the pitch immediately.

### Validating a lead list
A marketing team gets a spreadsheet of domains. You ask your agent to run `find_company` on all of them. The agent returns the industry and size for every single domain, allowing you to segment the list before sending it to sales.

### Auditing an existing account
Before a renewal call, you ask your agent to use `get_watchlist` on the client's main domains. This quickly reminds everyone what key assets or historical contacts need attention during the meeting.

### Identifying competitor gaps
You suspect a target company might be hiding certain information. You ask your agent to run `find_risk` and also `reveal_ip` on their domain. This gives you an immediate, technical layer of context for the sales team.

## Benefits

- Contextualizing leads is easy. Instead of just having an email, your agent uses `find_person` to pull the person's job title, social profiles, and professional background instantly.
- Never guess a company's size again. By using `find_company`, you get core firmographic data like industry, employee count, and revenue right from the domain name alone.
- Stop wasting time on dead ends. Use `get_prospects` to search for new companies based on criteria—like needing specific technology stacks or a minimum revenue level.
- Add risk context to every conversation. Running `find_risk` provides an immediate score, helping your team prioritize which leads are worth the call.
- Maintain compliance and focus. Because Vinkius manages all tool calls through its secure sandbox, you know your credentials are used only in transit for this enrichment process.

## How It Works

The bottom line is that you get deep B2B intelligence on demand, without having to navigate a single dashboard.

1. Subscribe to this MCP and enter your Clearbit API Key, which you get from your dashboard.
2. Ask your agent to enrich data using a specific piece of information, like an email or domain name.
3. The agent calls the necessary tools, pulls the structured data, and presents it back to you in plain text.

## Frequently Asked Questions

**How do I use `autocomplete_company`?**
`autocomplete_company` suggests company names and domains as you type, helping you correct typos or find the official name before running a full lookup.

**Can I find information on a company using only its domain with `find_company`?**
Yes. `find_company` takes a website domain and returns detailed firmographics, like the industry, size (employee count), and location.

**What is the best way to use `get_prospects`?**
You should specify clear criteria. For example, asking for 'SaaS companies in California with 100-500 employees' will give you a highly targeted list.

**Is `find_risk` the same as basic data lookup?**
No. While it uses underlying data, `find_risk` specifically calculates and reports an immediate risk score, giving you a prioritization metric that simple lookups skip.

**How does `find_person` work when I only have a company name?**
No, you must provide an email address to use `find_person`. This tool requires the email format for accurate person intelligence. If you only have a company name, try using `find_company` first.

**What is the difference between `get_watchlist` and general searching?**
`get_watchlist` retrieves pre-curated or saved lists of companies you've designated for monitoring. It doesn't search broadly; it pulls specific, tracked accounts that require attention.

**Does using `find_person_and_company` reveal private information?**
No, the data returned is publicly available B2B intelligence compiled by Clearbit. The MCP only passes through verified, non-private firmographic and professional details.

**Can I use `reveal_ip` to check for general company legitimacy?**
The `reveal_ip` tool provides the IP address associated with a connection. This is useful for technical audits, but it cannot validate overall business legitimacy or firmographic details.
