OpenCode with Stable Baseline.

1. Add the server

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "sb": {
      "type": "remote",
      "url": "https://api.stablebaseline.io/functions/v1/cloud-serve/mcp"
    }
  }
}

OpenCode signs you in when it first connects. You can also run it yourself:

opencode mcp auth sb     # sign in
opencode mcp list        # see each server and whether it is connected
opencode mcp logout sb   # sign out

Or use an API key

Create one under Organisation settings, Developers, API keys. See Setup. Refer to it through an environment variable, and turn OpenCode's own sign-in off for this server:

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "sb": {
      "type": "remote",
      "url": "https://api.stablebaseline.io/functions/v1/cloud-serve/mcp",
      "headers": {
        "Authorization": "Bearer {env:STABLE_BASELINE_API_KEY}"
      },
      "oauth": false
    }
  }
}

2. Document the repository

Type /sb:sb-setup and say what you want, for example “architecture docs for new engineers”. It then:

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.

Every Stable Baseline prompt appears the same way, such as /sb:sb-update. See the full list.

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.”
