- 2 Prompt your AI agent with a specific request, like 'What was the latest funding for OpenAI and who invested?'
- 3 The agent calls the necessary tools (e.g.,

The bottom line is, your AI client acts as a dedicated research analyst, calling the right data tools on demand to build a complete, narrative profile.

Real-World Use Cases
Due diligence on a potential acquisition
A Corp Dev needs to know if Target Inc. is worth the price. They prompt their agent: 'What's the funding history and current employee count for Target Inc.?' The agent uses list_funding_rounds and get_company_stats to pull the data, giving a quick picture of financial health and scale.
Identifying competitors' funding moves
A VC is tracking rivals. They ask the agent to search for competitors in the AI space and check their funding. The agent uses search_startups and list_funding_rounds to build a real-time competitive map.
Validating a founder's credentials
A recruiter gets a candidate's LinkedIn URL. They ask the agent to check the person's background. The agent runs enrich_person to confirm the candidate's full education and career path before the first interview.
Mapping out investor networks
A researcher needs to understand an angel investor's reach. They ask the agent to find the investor and then list their portfolio. The agent uses search_investors and get_investor_portfolio to map out connections.
The Tradeoffs
Manual data stitching
Logging into Harmonic, running a search for a company, copying the funding round data, then opening LinkedIn to check the founder's background, and finally opening a separate dashboard for stats. This takes 30 minutes.
→
Instead, prompt your agent with a single query: 'Give me the full profile for OpenAI.' The agent runs enrich_company, list_funding_rounds, and enrich_person in sequence, returning everything in one chat.
Searching only by name
Typing 'Google' into a general search bar and accepting the first result, which might be an old or unrelated entity. You miss the specific, structured data points.
→
Use search_startups with filters. You can narrow down results to 'Artificial Intelligence' in 'California' with '50-200' employees. This forces precision.
Assuming data freshness
Relying on an old spreadsheet of a company's funding rounds without checking if the data is current. You might miss a recent Series B round.
→
Always check the status first. Use get_enrichment_status to confirm that the background data refresh request is complete before relying on the numbers.
When It Fits, When It Doesn't
Use this if you need to build a complete, multi-layered profile on a target company or person. For example, if you need to know a company's founding history and its current funding rounds, this server is necessary. You must be able to tie together finance, people, and market activity.
Don't use this if your goal is simple data collection (e.g., 'What is the revenue of Company X?'). For simple metrics, a specialized finance API is better. Use this if the difficulty is in connecting the data points, not in finding them.

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 11 capabilities that interface natively with Claude, ChatGPT, Cursor, and any MCP client. No middleware. No custom integration required.
Available Capabilities
Building a company profile used to mean juggling five different platforms.
You start by checking Crunchbase for funding rounds, then switch to LinkedIn for the founder's career history. You copy-paste the domain into a separate web tool to check traction, and finally, you run a separate query for employee count. You spend time switching tabs and cross-referencing data.
With the Harmonic MCP Server, you ask your agent one question: 'Give me the full profile for Acme Corp.' It automatically runs `enrich_company`, `list_funding_rounds`, and `get_company_stats`, giving you a single, synthesized report that's ready to use.
Harmonic MCP Server: Get Investor & Market Intelligence
Before, figuring out who invested in a company required searching manually through investor databases, and then running a separate search to see what else that investor backed. It was slow and incomplete.
Now, you ask your agent to 'Show me the portfolio for Sequoia Capital.' It runs `search_investors` and `get_investor_portfolio`, mapping out the investor's entire network instantly. You don't just get a list; you get the context.
Common Questions About Harmonic MCP
How do I use the `list_funding_rounds` tool? +
You provide the company's domain name. The tool returns a list of all funding rounds, including the date, amount, and lead investors for that company.
What is the difference between `enrich_company` and `search_startups`? +
enrich_company takes a domain name and returns deep, specific data on that entity. search_startups lets you search a massive database using broad filters like industry or headcount.
Can I check a person's history with `enrich_person`? +
Yes, you provide a LinkedIn URL. The tool then pulls the person's professional background, including education history and career details.
Does `get_company_stats` include revenue? +
It provides growth statistics and headcount metrics. While it gives scale data, it does not pull specific revenue figures.
How do I find investment firms using `search_investors`? +
You can search by name or criteria. The tool helps you locate investment firms and angel investors so you can check their full portfolio history.
What can I use `get_investor_portfolio` for? +
The get_investor_portfolio tool lists all companies an investor has backed. You can use this to map out an investor's entire investment focus, seeing which industries or geographic areas they target.
How does `search_startups` filter by growth metrics? +
The search_startups tool uses advanced filters for metrics like headcount growth. You just specify the growth range and industry, and it returns a filtered list of matching companies.

No, list_company_news only pulls the most recent news and press releases. It gives you a real-time overview of a company's current public communications.
How do I find my Harmonic API Key? +
Log in to your Harmonic account, go to the Console, and navigate to the API section. You will be able to generate and copy your unique apikey from there.
What happens if a company is not found in the database? +
If a company is not found, Harmonic will return a 201 Enrichment Triggered status. This means a background update has been queued. You can check the status later using the get_enrichment_status tool.
Can I search for companies based on specific criteria? +
Yes! Use the search_startups tool. You can provide a JSON string with filters like headcount, location, or industry to find companies that match your investment or sales criteria.
Is the integration secure? +
Absolutely. The integration only accesses your data through your unique API key. Your credentials are encrypted and stored securely within the Vinkius Cloud infrastructure.
