Zoom
Official MCP4.5/5Excellent
Official MCP docs exist and the API underneath is mature; the practical gate is that the useful data (recordings, transcripts) lives on paid plans.

Slack
Official MCP4/5Good
Use the official server, not the popular community ones — same permissions model as the user, plus admin approval. Covers a curated subset of the Web API, not all 200+ methods.

Intercom
Official MCP4/5Good
Clean official server with read/write on conversations; the only gate is that Intercom itself is paid.

Twilio
Official MCP3.5/5Good
Genuinely agent-ready, and genuinely dangerous: write actions send real SMS and calls. Use a scoped API key, not account credentials.

Discord
Community MCP2.5/5Workable
Community-only and bot-token shaped: capable, but you own the security review and the setup. No llms.txt anywhere on discord.com.

Microsoft Teams
Community MCP2/5Limited
Hardest auth story in this category. No dedicated first-party Teams MCP server confirmed — plan for Graph, Entra consent and an admin in the room.
