Turn Slack into MCP tools

Give your AI agent Slack tools. Writ turns your Slack workflows into authenticated MCP tools your agent can call, taking real actions on your own account.

  "mcpServers": {
    "writ-slack": {
      "url": "https://api.usewrit.app/mcp/your-workspace",
      "headers": { "Authorization": "Bearer wt_8f2c...a91" }
    }
  }
}

Record the Slack task once, or describe it to an AI session, and Writ turns it into an MCP tool your agent can call, taking real actions on your own Slack account.

1. 1
   Record a Slack action once

   Open the recorder and open admin analytics on Slack in a real browser. Writ captures the steps, login and 2FA included, into a workflow.

2. 2
   Publish it as an MCP tool

   One click exposes the workflow as an MCP tool with a typed input schema, alongside a REST endpoint. Your agent picks it by its description.

3. 3
   Call it from any MCP client

   Point Claude Desktop, Claude Code, Cursor, or any MCP client at your Writ server. The Slack tool acts on your own account and returns structured output.

Browse supported MCP clients, see what's possible on workflows, or search for another site. Free to start. See pricing.

Read-only website-to-MCP tools can summarize a Slack page, but they can't do anything on it. Writ turns the Slack workflows you build into MCP tools your agent calls to take real actions (search, extract, submit), authenticated, on your own Slack account.

Writ runs on your own accounts, with your own credentials and data, on sites you are authorized to use.

Each tool is a real Slack workflow with a typed input schema and structured output. Your agent picks the right one by its description.

Example tool schema

{
  "name": "slack.export_members",
  "description": "Export the workspace member directory.",
  "input_schema": {
    "type": "object",
    "properties": {
      "query": { "type": "string", "description": "What to look up on Slack." }
    },
    "required": ["query"]
  }
}

Copy the config into your client and authenticate with a wt_ key. Tools appear automatically.

{
  "mcpServers": {
    "writ-slack": {
      "url": "https://api.usewrit.app/mcp/your-workspace",
      "headers": { "Authorization": "Bearer wt_8f2c...a91" }
    }
  }
}

  "mcpServers": {

      "url": "https://api.usewrit.app/mcp/your-workspace",
      "headers": { "Authorization": "Bearer csk_3a90...f4d" }
    }
  }
}

Writ signs into your own Slack workspace through a Persona, including SSO, and runs inside that authenticated session for UI-only actions.

Use Writ on your own Slack workspace. Authorized automation of your own account.
