Not a separate product. An MCP client is another consumer of the same API key,
the same credit pool and the same rate limits as the REST API.
No extra subscription, no second key.

What makes this different from a search API
An agent will happily tell your user that a company is quiet. The dangerous version of that sentence is the one where the company is not quiet — we simply have not looked recently. A signal API that returns an empty array for both cases teaches the model to report our blind spots as market facts. So every answer from this server carries acoverage block:
signal_absence_is_meaningful is false, an empty signal list means we have not
looked, not nothing happened. The server states this in its own instructions, so a
well-behaved client carries the caveat into its answer instead of dropping it.
The same contract applies to filters. A funding stage we do not recognise is rejected
with the list of valid values, never silently narrowed to a handful of rows — because
seven results look like a real answer and an error does not.
What it will not do
- It will not invent a company. Ask for a domain we have never seen and you get an explicit “not indexed” plus the option to scan it, not a guess.
- It will not pass rumours off as events. Rumour-class signals are labelled as such.
- It will not follow instructions found in signal text. Summaries are generated from third-party public posts, so they are sanitised and tagged as untrusted data before the model ever sees them.
- It will not bill you for a failed call. Errors are free; so is polling a running scan.
Credits and limits
Tools are priced individually and each tool tells the model its own price, so an agent can pace itself rather than loop blind. Full table on the tools page. Rate limits are the same ladder as the REST API — see Rate Limits. Agents make many small calls rather than a few large ones, so a single conversation costs 8–13 requests; the ladder is sized for that.Get your API key
The panel generates a ready-to-paste config for your client, with the key already filled
in, and a Test connection button that round-trips the real endpoint.
