About MCP Servers for Slack, Email & Messaging

MCP servers for sending messages, managing channels, and automating communication platforms. Nerq tracks 1,205 MCP servers in the slack, email & messaging category, each assessed against 52 global AI regulations including the EU AI Act, US state AI laws (California SB53, Colorado SB205), UK AI Bill, and more. Compliance scores are weighted by jurisdiction penalty severity — jurisdictions with higher fines (like the EU AI Act at up to €35M) have more impact on the score than voluntary frameworks.
