Best Slack MCP Servers in 2026
So much project context lives in Slack threads that never makes it into tickets. A Slack MCP server lets the agent search channels, read discussions, and draft replies — closing the gap between "discussed in Slack" and "implemented in code."
Setup requires a Slack app with bot scopes. Read-only scopes (channels:history, search:read) are the safe starting point; add chat:write only when you have a workflow that needs the agent to post.

FAQ
Which Slack scopes should I grant?
Start with channels:read, channels:history, and search:read for a read-only setup. The agent can then find and summarize discussions without any ability to post. Add chat:write deliberately, and consider restricting it to one sandbox channel.
Can the agent summarize a busy channel?
Yes — fetching recent history and summarizing is the most popular workflow. Pair it with a research skill from the category below for structured, cited digests of long threads.
Does it work with private channels?
Only if you invite the bot into them and grant groups:history. Treat that as a deliberate decision — private channels often contain sensitive context.
