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.

  name: WINN.AI MCP API
  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.
