AgentData MCP server

AgentData MCP Server

Free company data for AI agents, as MCP tools. AgentData profiles companies from the public web: tech stacks, web signals (pricing page, free trial, API docs, careers), email addresses with their verification status, people with titles, and switch signals (who just dropped or adopted a tool).

Works with Claude, Claude Code, ChatGPT, Codex, Gemini, Cursor, Windsurf, VS Code, GitHub Copilot, Zed, Cline and any other MCP client.

Quick start

No key is needed to look up a company's public profile, search companies, browse technologies or read switch signals. Emails and people need a free API key (1,000 contact reveals a day, no card): sign up at agentdata.run/signup and copy the key from agentdata.run/settings.

Claude (claude.ai, Desktop, mobile)

Settings, Connectors, Add custom connector, then paste:

https://mcp.agentdata.run/mcp

No sign-in: the company, technology and signal tools work straight away.

Claude Code

claude mcp add agentdata -- npx -y agentdata-mcp-server --api-key YOUR_API_KEY

Claude Desktop, Cursor, Windsurf, VS Code, Cline

Add to the client's MCP config (claudedesktopconfig.json, .cursor/mcp.json, mcp.json):

{
  "mcpServers": {
    "agentdata": {
      "command": "npx",
      "args": ["-y", "agentdata-mcp-server", "--api-key", "YOUR_API_KEY"]
    }
  }
}

Leave out --api-key to run anonymously (company profiles, technologies and signals; no emails or people).

Hosted (no install)

https://mcp.agentdata.run/mcp

Streamable HTTP. Send Authorization: Bearer YOURAPIKEY for emails and people; without a header it serves the anonymous tools. In Claude Code:

claude mcp add agentdata --transport http https://mcp.agentdata.run/mcp --header "Authorization: Bearer YOUR_API_KEY"

Tools

Every response ends with a usage line (reveals, requests and companies left), so an agent can pace itself. A domain that has not been profiled yet is crawled on request and answers "retry in about two minutes" without charging. Without a key, findpeople and getperson are not listed.

Limits

Nothing else is metered. Details at agentdata.run/pricing.

Example prompts

• "Which SaaS companies use Intercom? Give me small ones with a pricing page."
• "Look up linear.app: tech stack, and who runs engineering."
• "Who dropped Zendesk in the last 30 days?"
• "Find heads of sales at fintech companies that use HubSpot, with email addresses."
• "How many contact reveals do I have left today?"
