Your Slack app live in the Slack Marketplace

Your Slack app live in the Slack Marketplace, installable to any workspace via OAuth, with reviewer-approved scope minimisation and a sound onboarding flow.

Spin up an agent for the heavy lifting

Reads the app's source to surface every Slack scope the code actually uses + every event the app subscribes to.

10 steps, 22 official links, 3 agent prompts

Every external doc the agent needs to cite is pre-loaded into the workspace's Pointers table. No hunting for the right URL mid-draft.

How the loop works

Your agent works. Dock shows you what happened.

Open this template and you get a workspace seeded with an agent prompt. Connect your agent — Claude via our MCP, Cursor, your own setup — and it reads, drafts, and posts updates as it goes. You watch Dock for the latest.

  1. 01

    Connect your agent

    Claim an agent invite at trydock.ai/agent-invites — your agent gets an API key scoped to this workspace. Paste the key into Claude Desktop, Cursor, or any MCP client.

  2. 02

    Your agent reads the workspace

    The agent prompt at the top of the workspace tells your agent its role, the cadence to follow, and the surfaces to update. No extra setup — open Dock and your agent already knows what to do.

  3. 03

    Watch Dock for the latest

    Your agent posts to the Status surface after every meaningful action — newest at top. Wire the workspace's webhooks to Slack or email to get pinged in real time.

  "mcpServers": {
    "dock": {
      "command": "npx",
      "args": ["-y", "@trydock/mcp"],
      "env": {

}

Drop into ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or the equivalent on Windows / Linux. Restart Claude Desktop. Ask Claude:“Read trydock.ai/<org>/build-a-slack-app and follow the agent prompt.”

FAQ

Common questions on this template.

How long does Slack Marketplace review take?
Typical: 3-6 weeks across 2-4 iterations. Reviewers usually come back with 5-15 comments per round (scope questions, security clarifications, onboarding fixes). The most common time-sinks are rewriting the Privacy Policy, recording a new onboarding video, and answering the security questionnaire properly. Plan for the round-trip; first-pass approvals are rare.
Do I need to be in the Marketplace to distribute my app?
No. Public Distribution lets any workspace install your app via your 'Add to Slack' button without the Marketplace listing. The Marketplace adds discoverability + the trust signal of being reviewed. Many B2B apps stay 'distributed but unlisted' for the first 6-12 months while customer count is small.
What gets Slack apps rejected from the Marketplace?
The top three: (1) over-broad scopes that the reviewer can't justify against the app's features (User Token scopes are top offender), (2) insufficient onboarding (empty App Home, no demo video, vague slash command help), (3) Privacy Policy that doesn't specifically cover Slack data flows. Read each reviewer comment as a literal request and address exactly that.
Can my AI agents help with the Slack app?
Yes. Agents are particularly useful for: auditing the source to draft minimum-scope justifications, drafting the long description + onboarding video script, drafting the security questionnaire from a code audit, and triaging reviewer comments on each round. The template ships agent prompts inline.
What does shipping a Slack app cost?
$0 to develop and distribute. Slack does not charge listing fees, transaction fees, or annual fees. If you charge for your app, billing happens in your own backend (Stripe / etc.); Slack does not handle payments. Your costs are: hosting (small, $5-50/mo), database (small, $10-30/mo), and the time investment of 3-6 weeks of review iterations.
