Slack MCP for AI agents

Connect Slack to Claude, Cursor, and other MCP clients through MCPGRAM — one OAuth connection, governed tools, no per-client Slack app wiring.

Connect SlackRead docs

What you get

  • Workspace-scoped OAuth; agents only see tools for workspaces you approve.
  • Send and read channel messages using channel IDs (bot must be invited).
  • Same MCP endpoint as every other MCPGRAM connector.

Example tools

  • List channels
  • Send message (channel ID)
  • Read channel history

How agents connect

  1. Sign up and open a workspace on MCPGRAM.
  2. Connect Slack with OAuth (tokens stay in your workspace).
  3. Point Claude / Cursor at https://mcpgram-mcp-server.vercel.app/mcp or use an API key on https://mcpgram.vercel.app/api/mcp.
  4. Call Slack tools through the universal tool layer.

Notes

Use the channel ID, not the channel name. Invite the MCPGRAM bot to private channels before sending.

Auth errors surface as clear MCP tool errors (e.g. not_in_channel, invalid_auth).
