In the chat, type @ followed by the MCP server name and your instructions, e.g., "@AgentData: customer lists of B2B software Look up acme.com for their tech stack and key people"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Customer lists of B2B software for AI agents. Ask who uses a technology (HubSpot, Zendesk, Stripe, Shopify and thousands more) and get the companies, each with how we found it, in the website's code or its public DNS records, and when we first and last saw it. Also: the companies that just started using a technology, one company's technologies grouped by category, and CSV downloads of the lists on your plan.

Claude Code:
claude mcp add --transport http agentdata https://mcp.useagentdata.com/mcpor, with your key and no sign-in step:
claude mcp add --transport http agentdata https://mcp.useagentdata.com/mcp --header "Authorization: Bearer YOUR_API_KEY"Cursor and other clients: the URL with an Authorization: Bearer YOUR_API_KEY header.
Local (stdio) clients:
npx agentdata-mcp-server --api-key YOUR_API_KEYThe package is a small bridge: each message goes to the hosted server with your key.
Your API key is in your account settings at useagentdata.com/app/settings#api. Generating a new key disconnects anything that uses the old one. Apps you connected by signing in are listed under Connected apps on the same page.

Scored across 6 tools
Each tool targets a specific function: account usage, people search, signals, technologies, company details, and company search. While lookup_company includes team members, its primary focus is company enrichment, distinct from find_people's cross-company search. Overlaps are minimal and descriptions clarify boundaries.
All tools follow a consistent verb_noun pattern in snake_case (e.g., find_people, get_signals, search_companies). The naming is predictable and intuitive, with clear action and target.
With 6 tools, the server is well-scoped for its purpose of people and company intelligence. Each tool addresses a distinct need without redundancy, and the count is neither too sparse nor overwhelming.
The tool set covers core workflows: account management, person search, company search and enrichment, technology browsing, and signal tracking. There are no obvious gaps for the intended domain of B2B data enrichment.
