Search for leads
Describe your ICP and Derrick returns matching, ready-to-work leads right in the chat.
Model Context Protocol
Turn your AI chat into a B2B prospecting workspace.
The Derrick MCP gives Claude, ChatGPT, Cursor and any AI agent live access to find emails, phones, LinkedIn data, company firmographics, tech stacks and SIRET - all by chat. No tab-switching, no scaffolding.
Your whole prospecting workflow. One conversation.
Teams already research with AI, then lose the thread the moment they need real data, jumping to a database, a finder, a scraper, a CRM. Derrick closes that gap: the chat stays the workspace, and Derrick is the data engine behind it. Ask for leads, emails, phones or firmographics and the agent runs the lookup and hands back clean rows, without you leaving the conversation.
Everything you'd do, just by asking.
No new tool to learn. Prompt your AI like a teammate; Derrick does the data work and answers right in the chat.

Frequently Asked Questions
What is the Derrick MCP?
+
It's a Model Context Protocol server that gives any AI agent - Claude, ChatGPT, Cursor, Windsurf - live access to Derrick's B2B enrichment. Instead of switching to a tool, you ask in plain English ("enrich these leads, find their phones") and the agent runs the multi-source lookup through Derrick and returns the data inline. Same backend as the Google Sheets add-on and the REST API.
How do I connect it to Claude?
+
In Claude, open Customize → Connectors → + Add custom connector, name it Derrick and paste https://app1.derrick-app.com/mcp. Prefer the terminal? Use the one-line Claude Code command in the "Set it up" section above. Derrick asks for your API key when you connect.
Do I need an API key, and a paid plan?
+
The MCP installs without credentials, but calling tools needs a Derrick API key - and keys unlock from the Standard plan (€20/mo, 10,000 credits). The Free (100 credits) and Mini (€9/mo) tiers don't expose API/MCP access. Get the key in the Sheets add-on → Settings → API access.
How much does an MCP call cost?
+
Credits are charged per tool, not flat: find_email = 5, find_phone = 150, enrich_profile = 1, verify_email = 1, search = 1 per result. €/credit varies by plan, from €0.002 on Standard down to €0.0016 on the highest tier. The derrick_credits tool returns your live balance so the agent can budget.
Which AI clients can connect?
+
Any MCP-compliant client. We document Claude (Desktop, web, Code), ChatGPT (developer-mode connectors), Cursor and Windsurf, but the JSON config pattern works for Continue, custom MCP-SDK agents and anything else on the spec.
Is it real-time?
+
Yes. Every call hits the same backend as the Sheets add-on, cross-referencing 15+ data providers live per request. No batch-cache lag - if a person's email changed yesterday, you get the new one today.
How is this different from the REST API?
+
Same backend, different surface. The REST API is for code integrations (Zapier, Make, your scripts). The MCP is for AI agent workflows - the agent calls Derrick natively as tools, so you prompt "find me 50 leads matching X" and it figures out which tools to chain.
Is it GDPR-compliant?
+
Yes. Derrick processes only publicly-available B2B data and stores nothing - every MCP call is stateless. Our DPA is available on the DPA page for enterprise customers.
