# 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

- Address: `https://mcp.slack.com/mcp`[1]
- Sign-in: Confidential OAuth with a Slack app[1]
- Allowed apps: Directory-published or internal apps[1]

## 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.
