Slack MCP without OAuth — 21 tools, session-based, local-first. Free OSS + hosted tier from $19/mo.
Turn Slack from an interruption stream into searchable operating memory and approved action. The open-source local path ships 21 tools today through the browser session you already have—no Slack app, scope review, or admin queue. Hosted adds permanent OAuth, indexing, scheduled intelligence, and team continuity when the workflow must run without you.
Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
