Free company data for AI agents: profiles, tech stacks, contact details and people. No sign-in.
Quick Install
Automated & IDE SetupCopy the AI prompt to install this server into Claude Code, Cursor, or another agent — or use 1-click editor setup below.
One-click editor setup isn’t available for this listing yet — we don’t have a confirmed install command, and we’d rather show nothing than point your editor at the wrong package or host. Follow the project’s own setup instructions, linked above.
Manual Client & Custom JSON ConfigExpand JSON â–¾
No confirmed setup config for this listing yet. We only publish a config block when the install details come from the project itself — its README, its docs, or a verified owner. We haven’t found those for AgentData, and we’d rather show nothing than a guess you’d paste into your client. Follow the project’s own setup instructions for the current steps.
Documentation Overview
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:
No sign-in: the company, technology and signal tools work straight away.
Claude Code
Claude Desktop, Cursor, Windsurf, VS Code, Cline
Add to the client's MCP config (claude_desktop_config.json, .cursor/mcp.json, mcp.json):
Leave out --api-key to run anonymously (company profiles, technologies and signals; no emails or people).
Hosted (no install)
Streamable HTTP. Send Authorization: Bearer YOUR_API_KEY for emails and people; without a header it serves the anonymous tools. In Claude Code:
Tools
| Tool | What it returns | Cost | Key |
|---|---|---|---|
lookup_company | One domain's record: company, tech stack (first and last seen), signals, email pattern. With a key, also email addresses and people | none without a key; with a key 1 reveal per domain per 30 days | no |
search_companies | Companies by name or by sector, size (estimate), b2b/b2c, model, technology, country | none | no |
get_technologies | The technology index, or companies using one technology | none | no |
get_signals | Companies that added, removed or switched a tool; growth and hiring changes | none | no |
find_people | People by title, seniority, department, company filters | 1 reveal per company in the response | yes |
get_person | One person by id, with email | 1 reveal (free if the company was revealed in the last 30 days) | yes |
check_usage | Plan and what is left today | none | no |
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, find_people and get_person are not listed.
Limits
| Anonymous | Free key | Pro ($99 a year) | |
|---|---|---|---|
| Contact reveals a day | none | 1,000 | 10,000 |
| Requests per 5 hours | 300 | 5,000 | 25,000 |
| Requests a second | 2 | 5 | 20 |
| Distinct companies a day | 200 | 5,000 | 25,000 |
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?"
Run from source
AGENTDATA_API_KEY, PORT and HOST work as environment variables. npm run inspect opens the MCP Inspector.
The HTTP server binds to 127.0.0.1 by default and only answers local pages, so a key you start it with cannot be used by other sites or other machines. --host 0.0.0.0 makes it public; in that mode the startup key is ignored and every caller must send its own Authorization: Bearer key.
