Cursor with Stable Baseline.

1. Install

Add to Cursor

Opens Cursor with the Stable Baseline server filled in. Cursor then asks you to sign in.

Or add it by hand: in .cursor/mcp.json for this project, or ~/.cursor/mcp.json for every project.

{
  "mcpServers": {
    "sb": {
      "url": "https://api.stablebaseline.io/functions/v1/cloud-serve/mcp"
    }
  }
}

Cursor shows that the server needs you to sign in; follow it to your browser, sign in to Stable Baseline and choose what Cursor may reach.

Or use an API key

Create one under Organisation settings, Developers, API keys. See Setup. Then refer to it from the config through an environment variable:

{
  "mcpServers": {
    "sb": {
      "url": "https://api.stablebaseline.io/functions/v1/cloud-serve/mcp",
      "headers": {
        "Authorization": "Bearer ${env:STABLE_BASELINE_API_KEY}"
      }
    }
  }
}

2. Document the repository

If Cursor lists Stable Baseline's prompts, run sb-setup. Otherwise ask its agent in plain words:

Document this repository in my Stable Baseline project. Use the Stable Baseline tools to find my workspace and project (do not create them), read the code, design a structure of folders, documents and diagrams, write them, and add a Stable Baseline section to AGENTS.md so you keep the docs current as the code changes.

Either way, the work follows the same steps:

1. 1

   Checks the connection

   It confirms it can reach Stable Baseline with your key or sign-in.
2. 2

   Finds your workspace and project

   It never creates them: if it cannot find the ones you mean, it asks you to create them in the app first.
3. 3

   Remembers them

   It writes their ids to .sb/config.json, and keeps .sb/ out of git.
4. 4

   Checks for existing docs

   If the project already has documentation, it asks whether to add to it, replace it, or stop.
5. 5

   Reads the repository

   It works through the code to understand what is there.
6. 6

   Designs a structure

   Folders and documents that fit this repository, not a fixed template.
7. 7

   Writes it

   Folders, documents, and the diagrams each document needs.
8. 8

   Updates AGENTS.md

   It adds a Stable Baseline section with rules for keeping the docs current, and keeps everything else in the file.
9. 9

   Sums up

   It tells you what it created.

3. Try it

• “What changed in the checkout service this week? Update its document.”
• “Add a sequence diagram of the sign-in flow to the authentication document.”
• “Create a plan for the database migration with three phases.”
• “Log a risk in the work register: the payment provider's rate limits.”
