Do I need to write code?

No. You add a config block once, then ask for signals in natural language.

How fresh is the data?

Signals are detected and verified in under a minute from the moment they appear publicly. Executive hiring posts typically surface three to four weeks before the role reaches a job board.

Can I use this with Claude Desktop or Cursor?

Yes. The same MCP server works with any MCP-compatible client, including Claude Desktop and Cursor. The config block is identical.

Plans start at €200/month including 2,000 signals. There is a 7-day trial with 500 signals.

Is there a rate limit?

There is a default per-endpoint rate limit, raised on request for higher-volume use. Interactive sessions never come close to it.

Signalbase + Claude Code integration

Signalbase runs as an MCP server, which means Claude Code can query live company signals the same way it reads your codebase. Ask for funded companies in your market, companies hiring for a specific role, or executives who just changed jobs, and Claude pulls verified signals with sources attached and works with them directly: filtering, cross-referencing, writing them to a file, or feeding them into whatever you are building.

No SDK, no wrapper, no glue code. One config block and the signals are available as a tool.

What you can do

Build a prospect list in one prompt. "Find companies that raised Series A in the Netherlands in the last 30 days and are hiring engineers" returns a filtered, sourced list you can write straight to CSV.
Qualify an existing list. Point Claude at a file of domains and have it check each one against live signals, so you know which accounts have something happening right now.
Cross-reference signals. Funding plus hiring plus a new executive is a much stronger trigger than any one alone. Claude can chain those queries in a single session.
Monitor a market overnight. Give Claude a niche and a schedule, and have it report what changed since yesterday.
