## What it does

The plugin gives the agent access to Slack via an integration you set up. Under the hood it ships an MCP config, `.mcp.json`, with an OAuth `client_id` published in the open. No client secret is included.

That makes it a public OAuth client. The ID can be copied to impersonate the client in OAuth requests, and it cannot prove a request came from this plugin. Access to a Slack account still needs user authorization, so nothing gets read until someone approves it.

If Slack is where your team makes decisions, this is a reason to look at how workspace access is handed out. Built for Codex and ChatGPT.

## Requirements
- Works with: Slack

## When to use it
- read a Slack channel discussion from the agent
- find a specific thread in team chat
- check what was agreed in chat against the code
- pull context out of Slack without switching windows

## Example prompts
- show the latest messages in #general
- find the Slack thread about the deploy and summarize it
- what was posted in #backend today

**Warning: this plugin is a public OAuth client.** Its OAuth `client_id` is
published in [`.mcp.json`](.mcp.json), and no client secret is included. The public
ID can be copied to impersonate the client in OAuth requests; it cannot prove
that a request comes from this plugin. Access to a Slack account still requires
user authorization.
