Before you connect: what this server would do
A preview derived from this server’s definition — not a live run. Nothing runs and no key is sent until you connect. You connect directly to the provider’s own server with their sign-in.
Tools it can use (5)
- b4_browseCan change data
Search and filter the B4 Index's 1,600+ independently scored software categories. Browse by keyword, domain, quadrant, or industry. When filtering by industry, returns all vertical categories for that industry PLUS all horizontal categories (which apply to every industry). Each row carries its banded verdict — primary, confidence word, and a near-call flag — and the quadrant filter matches the verdict at whichever lens you are reading. Verdicts are banded (B4 methodology v4.0), not point calls:
- b4_scoreCan change data
Score a software category using the B4 Index. Provide a known category name to get pre-computed scores, or provide raw dimension scores (1-5 each) for a custom evaluation. Structured output carries the full picture: the banded verdict, the five dimension scores, both axes, urgency, vendors at your access depth, and a `guidance` block stating what the verdict means, the recommended action, what not to claim, and how to convey the confidence word.

Follow that guidance
- b4_recommendCan change data

What FindAgent checked
- It passed an automated security scan and a human review before it was published here.
- Your client talks to this server directly, so FindAgent’s run-time protections — the prompt-injection deny-list on what you send, the secret-leak scan on every result, the credential-to-host binding, the approval gates — do not apply to what you send or receive here.
Connect over MCP — runs anywhere

You add this server inside your client and approve it once — that in-client step is a security check, so there's no one-click button for it.
