Crayon Competitive Intelligence MCP Server

Hosted Model Context Protocol server exposing a customer's curated Crayon competitive intelligence — battlecards, win/loss stories, competitor profiles, objection handling and customer proof points — to MCP-capable assistants such as Claude, ChatGPT, Glean, Microsoft Copilot, Google Gemini and internal Slack or Teams bots. JSON-RPC over Streamable HTTP, protected by OAuth 2.1 with dynamic client registration and the single scope mcp:read. Verified live: an anonymous tools/list POST returns HTTP 401 with an RFC 9728 resource_metadata challenge, so the tool set is auth-gated.
