Winn.ai

Winn.ai is an AI-powered revenue execution platform for B2B sales teams that joins live sales calls to provide real-time playbook guidance, coach representatives on messaging and objection handling, and automate administrative work such as meeting note-taking, follow-up drafting, and CRM data entry. The product sits on top of a team's existing sales stack and reports outcomes including higher playbook adoption, dramatically higher CRM fill rates, and a large reduction in post-call admin work. Winn.ai is a privately held company backed by Insight Partners. WINN.AI sells API access as an Enterprise-plan feature ("Get conversation data and AI insights, in any tool") and runs a live, undocumented remote Model Context Protocol server at https://app.winn.ai/mcp, discovered through the RFC 9728 OAuth protected-resource metadata it publishes; the endpoint is gated by OAuth 2.0 authorization code with PKCE and advertises a single read-only scope, sessions:read. There is no developer portal, API reference, OpenAPI document, SDK, CLI, webhook catalog, status page or changelog, and both pricing tiers are sales-gated. The company operates a Vanta-hosted trust center covering SOC 2, ISO 27001 and GDPR.

Winn.ai publishes 1 API on the APIs.io network. Tagged areas include Company, Sales, Artificial Intelligence, Revenue, and CRM.

Winn.ai’s developer surface includes pricing, support, authentication, and 17 more developer resources.

Kin Score Kin Score How this is scored →
scored 2026-09-25 · rubric v0.23.0
Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/winnai: open an issue to ask a question, or submit a pull request to add artifacts.

  description: A live remote Model Context Protocol endpoint serving WINN.AI conversation data to agents. It is published
    nowhere on the company's website — it was found by probing RFC 9728 OAuth protected-resource metadata on the product application
    host, which names https://app.winn.ai/mcp as the protected resource. Every anonymous JSON-RPC call, including initialize
    and tools/list, returns HTTP 401 {"error":"Missing credential"}, so the tool set is not public. Access is bearer-token-only
    via OAuth 2.0 authorization code with PKCE (S256), with dynamic client registration supported, and the sole advertised
    scope is read-only (sessions:read). Commercially this is the Enterprise-tier "API access" feature, reached through sales
    rather than signup.
