Slack in Best MCP Servers for Business
Answer in brief
Best for agents that search and post in Slack.
Resource role
Team chat. Slack's server at https://mcp.slack.com/mcp lets apps search channels, send messages and take other Slack actions.1 Every client must be backed by a registered Slack app, and only directory-published or internal apps may use it.1
It covers search, messages, files and lists, within per-method rate limits.1
Relationship to Conecto
Slack is a separate resource. Conecto doesn't make it and has no partnership with Slack. Conecto is our editorial choice for a small business that wants its back office in one MCP server: a CRM, invoices, books, e-signature and a help desk, paid per call.
The facts
What to inspect
Slack supports neither SSE nor dynamic client registration yet, so the client needs its own Slack app ID.1
Register a Slack app with a fixed app ID, use its client ID and secret for OAuth, and have users approve it. Workspace admins approve the app through the usual Slack process.1
Who it fits
Pick it when your team works in Slack and you want an agent to search or post there.
