Introduction

OpenClaw is the fastest growing agent harness out there, which can work 24/7 to automate almost any kind of tasks. However, its capabilities are limited to the tools it has access to. Composio allows your OpenClaw to access Slackbot with authentication management handled for you. You can execute actions on Slackbot via your favorite OpenClaw interface (Telegram, WhatsApp, TUI, etc), whichever you prefer.

Why use Composio?

Apart from a managed and hosted MCP server, you will get:

Programmatic tool calling allows LLMs to write its code in a remote workbench to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
Handling Large tool responses out of LLM context to minimize context rot.
Dynamic just-in-time access to 20,000 tools across 1500+ other Apps for cross-app workflows. It loads the tools you need, so LLMs aren't overwhelmed by tools you don't need.

How to install Slackbot with OpenClaw

Using Composio API Key and Setup Prompt

Go to dashboard.composio.dev
Copy the setup prompt

Copy the setup prompt from the OpenClaw dashboard

Run it in your OpenClaw chat interface.
Authenticate Slackbot from the dashboard
Go back to your OpenClaw interface and start asking questions.

Using OpenClaw/Composio Plugin

1. Install OpenClaw Composio plugin

bash

openclaw plugins install @composio/openclaw-plugin

2. Copy the API Key from dashboard.composio.dev

3. Setup OpenClaw Config

bash

openclaw config set plugins.entries.composio.config.consumerKey "ck_your_key_here"

4. Restart OpenClaw

bash

openclaw gateway restart

5. Go to your chat interface and start asking questions.

6. When prompted, authenticate the app and you're all set.

How It Works

The plugin connects to Composio's MCP server at https://connect.composio.dev/mcp and registers all available tools directly into the OpenClaw agent. Tools are called by name — no extra search or execute steps needed.

If a tool returns an auth error, the agent will prompt you to connect that toolkit at dashboard.composio.dev.

Configuration

bash

{
  "plugins": {
    "entries": {
      "composio": {
        "enabled": true,
        "config": {
          "consumerKey": "ck_your_key_here"
        }
      }
    }
  }
}

Option	Description	Default
`enabled`	Enable or disable the plugin	`true`
`consumerKey`	Your Composio consumer key (`ck_...`)	—
`mcpUrl`	MCP server URL (advanced)	`https://connect.composio.dev/mcp`

What is the Slackbot MCP server, and what's possible with it?

The Slackbot MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Slack workspace. It provides structured and secure access to workspace messages, files, channels, users, canvases, lists, and reminders, so your agent can search conversations, read channel history, send messages, manage shared content, and schedule follow-ups on your behalf.

Workspace-wide search: Instruct your agent to search messages and files across channels and direct messages using keywords, dates, and other filters.
Conversation and channel access: Have your agent find channels, read conversation history, list unread channel messages, and retrieve unread direct messages from a specific user.
Messages, reactions, and reminders: Let the agent send, schedule, or update Slack messages, add or remove emoji reactions, and create reminders for future tasks.
User and workspace discovery: Direct your agent to find coworkers by name or email, browse workspace users and channels, and identify available workspaces.
Canvases, lists, and files: Have your agent create or edit canvases, manage Slack Lists and their items or access, and download files shared in Slack.

Conclusion

You've successfully integrated Slackbot with OpenClaw using Composio plugin. Now interact with Slackbot directly from your terminal, Web UI, or any messenger app using natural language commands.

Key benefits of this setup:

Seamless integration across TUI, Web UIs, and Messenger apps like Telegram, WhatsApp, Slack, etc.
Natural language commands for Slackbot operations

FAQ

Frequently asked questions

With a standalone Slackbot MCP server, the agents and LLMs can only access a fixed set of Slackbot tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Slackbot and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. OpenClaw fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Slackbot tools.

Yes, absolutely. You can configure which Slackbot scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Slackbot data and credentials are handled as safely as possible.
