Best MCP Servers for Communication & Messaging
Email, chat platforms, and notifications - MCP servers for team communication and messaging.
MCPpedia tracks 888 communication and messaging MCP servers. 241 of them score at least 50 out of 100, and 132 clear 70 - about 15% of what has been published in this space. The remaining 647 are thinner: registry entries with no description, no published tool schema, or no commit in the last year. They are all still listed here, because knowing a server exists and is unmaintained is worth as much as knowing a good one exists.
io.github.team-telnyx/telnyx leads the list at 95/100. app.mailtea/mailtea (92) and com.mcpemails/emails (92) follow. Every score is the same five weighted inputs: security (CVE scanning, tool-poisoning detection, and whether the server authenticates at all), maintenance (commit recency, release cadence, and download trend), documentation, client compatibility, and token efficiency - how much of your context window the tool definitions consume before you have asked anything.
5 of these servers are published by the vendor behind the underlying API rather than by a third party, which is usually the difference between an integration that tracks upstream changes and one that quietly stops working. 2 currently carry an open CVE; those are flagged on the server's own page with the advisory and its severity.
