Reachdesk MCP Server
Reachdesk operates a first-party remote Model Context Protocol server at https://app.reachdesk.com/mcp, on the same host as its REST API. It is a hosted HTTP endpoint an MCP client POSTs to directly — there is no stdio package to install. Access is OAuth 2.1 with dynamic client registration (RFC 7591), PKCE S256, and two published scopes, mcp:tools.user.read and mcp:tools.user.write, which scope tools to the authenticated Reachdesk user. The server is undocumented in Reachdesk's knowledge base and API reference; it was found by probing the API host, and the tool list is auth-gated.
