# Connect Slack to your AI agent

> Yes — ClawLink is a hosted Slack MCP server. 145 tools your agent can call from chat, with one-click hosted OAuth and nothing to run locally.

Web version: https://claw-link.dev/hub/slack

ClawLink hosts a managed Slack MCP server that exposes 145 tools to your AI agent. You connect Slack in one click, and your agent can read, create, and update Slack data from chat without you building or running a local MCP server.

## Quick facts

- 145 tools callable from chat
- One-click hosted OAuth
- Works with OpenClaw, Hermes, Claude Code, Cursor, Codex, and any MCP client
- No local server or config files

## Overview

The usual path is: build auth, handle token refresh, wire up the tools. With ClawLink you connect Slack once and start using the real actions from the agent.

## Setup

Slack uses OAuth. You connect it in the browser: click Connect, sign in, approve. ClawLink stores the token and refreshes it on its own. You never touch a key or wire up a redirect URL.

Authentication: hosted OAuth

## What you can do

- **Triage from chat** — Ask in plain English. The agent pulls up the right Slack thread, channel, or inbox so you stay in one window.
- **Draft, then send** — The agent writes a message in Slack, shows you the draft, and sends once you say go.
- **Context in one place** — Message history, who's involved, and recent activity from Slack sit next to the work you're doing.

## ClawLink vs. building it yourself

| | Manual | ClawLink |
|---|---|---|
| Connection | Build it yourself. You register a developer app with Slack, set up redirect URLs, handle the consent screen, store and refresh access tokens, and redo the wiring when scopes change. | Hosted hosted OAuth. Connect once in the browser. ClawLink owns the lifecycle. |
| Maintenance | Token refresh, permission debugging, env config, every edge case. All yours. | ClawLink handles the plumbing. You focus on the workflow. |
| Time to first call | Days to weeks. Auth, storage, tool wiring, testing. Then the agent can act. | About two minutes from sign-up to the agent calling Slack. |

## FAQ

### How do I connect Slack to my AI agent?

Install ClawLink, open the dashboard, click Connect next to Slack, and finish the hosted OAuth flow. Your agent can call Slack from the next message. Two minutes, total.

### Is there a Slack MCP server I can use?

Yes. ClawLink exposes Slack as 145 tools your agent calls through a hosted MCP-compatible runtime. You don't run a local server or edit a config file. The tools are there the moment you connect.

### Do I need Slack API credentials?

No separate API key. You sign in to Slack through the normal OAuth flow and ClawLink handles the token after that.

### How much does it cost?

Your first integration is free, plus a 7-day trial of the full catalog. Paid plans unlock the rest of the library.

### Can I set this up from the terminal instead of the dashboard?

Yes. Run npx -y @useclawlink/cli login, then npx -y @useclawlink/cli connect slack. The first opens a browser to sign in to ClawLink. The second opens a browser to authorize Slack. No API keys to create. Works with OpenClaw, Hermes, Claude Code, Cursor, Codex, and any agent that runs shell commands.
