Slack

With Cursor's integration for Slack, you can use Cloud Agents to work on your tasks directly from Slack by mentioning @cursor with a prompt.

Get started

Installation

1. Go to Cursor integrations

2. Click Connect next to Slack or go to installation page from here

3. You'll be prompted to install the Cursor app for Slack in your workspace.

4. After installing in Slack, you'll be redirected back to Cursor to finalize setup

   1. Connect a repository provider (if not already connected) and pick a default repository
   2. Enable usage-based pricing
   3. Confirm privacy settings

5. Start using Cloud Agents in Slack by mentioning @cursor

How to use

Mention @cursor and give your prompt. Cursor tries to detect a repository, model, base branch, or named cloud agent environment from your message. It also uses your recent agent activity when selecting a repository.

For a named environment, include its name in your prompt. For example: @Cursor use the Platform environment to update the shared API.

Commands

Run @Cursor help for an up-to-date command list.

Options

Customize Cloud Agent behavior with these options:

Syntax formats

Natural:

@Cursor with opus, fix the login bug in backend-api

Inline:

@Cursor env=Platform branch=dev model=opus autopr=false Fix the login bug

Use quotes for environment names with spaces:

@Cursor env="Platform Services" Update the shared API

Option precedence

When combining options:

• Explicit values override defaults
• Later values override earlier ones if duplicated
• Inline options take precedence over settings modal defaults
• env takes precedence over repo when both are present

The bot parses options from anywhere in the message, allowing natural command writing.

Using thread context

Cloud Agents understand and use context from existing thread discussions. Useful when your team discusses an issue and you want the agent to implement the solution based on that conversation.

When to use force commands

When do I need @Cursor agent?

In threads with existing agents, @Cursor [prompt] adds followup instructions (only works if you own the agent). To launch a separate agent, use @Cursor agent [prompt], or ask in natural language:

@Cursor start a new agent to refactor billing

Phrases like "create a new agent", "launch a fresh agent", or "new agent please" work the same way.

When do I need Add follow-up (from context menu)?

Use the context menu (⋯) on an agent's response for followup instructions. Useful when multiple agents exist in a thread and you need to specify which one to follow up on.

Status updates & handoff

When Cloud Agent runs, you first get an option to Open in Cursor.

When Cloud Agent completes, you get a notification in Slack and an option to view the created PR in GitHub.

Managing agents

To see all running agents, run @Cursor list my agents.

Manage Cloud Agents using the context menu by clicking the three dots (⋯) on any agent message.

Available options:

• Add follow-up: Add instructions to an existing agent
• Delete: Stop and archive the Cloud Agent
• View request ID: View unique request ID for troubleshooting (include when contacting support)
• Give feedback: Provide feedback about agent performance

Configuration

Manage default settings and privacy options from Dashboard → Cloud Agents.

Settings

Default Model

Used when no model is specified in your message. See settings for available options.

Repository Selection

Cursor automatically selects the right repository based on:

1. Your message content — Repository names or keywords in your prompt
2. Recent agent activity — Repositories you've used recently
3. Routing rules — Custom keyword-to-repo mappings (see below)
4. Default repository — Fallback when no match is found

To use a specific repository, include its name in your message. For example: @Cursor in mobile-app, fix the login bug.

Base Branch

Starting branch for Cloud Agent. Leave blank to use the repository's default branch (often main)

Channel Settings

Configure default settings at the channel level using @Cursor settings. These settings are per team and override your personal defaults for that channel.

Particularly useful when:

• Different channels work on different repositories
• Teams want consistent settings across all members

To configure channel settings:

1. Run @Cursor settings in the desired channel
2. Set the default repository for that channel
3. All team members using Cloud Agents in that channel use these defaults

Routing Rules

Routing rules let you define keywords that automatically map to a target. When your message contains a keyword, Cursor routes the agent to the associated repository or cloud agent environment. Environments can bundle multiple repositories, so one keyword can start an agent with every repo it needs already configured.

Setting up routing rules

1. Go to Dashboard → Cloud Agents
2. Find the Routing Rules section
3. Add keyword-to-target mappings, pointing each keyword at a repository or an environment

Example rules

With these rules configured:

• @Cursor fix the frontend nav bug → routes to acme/web-app
• @Cursor update the mobile onboarding flow → routes to acme/mobile-app
• @Cursor add a migration across the platform → starts in the Platform environment, with all its repos ready

How routing works

Cursor evaluates your message in this order:

1. Your message content — Repository names or keywords in your prompt
2. Recent agent activity — Repositories you've used recently
3. Routing rules — Custom keyword-to-target mappings (repository or environment)
4. Channel default — The repository set for this channel
5. Default repository — Fallback when no match is found
