What the code does

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

  const child = Bun.spawn(

                sql`EXISTS (SELECT 1 FROM ${sql.raw(t.table)} es WHERE es.site_snapshot_id = ss.id AND (es.${sql.raw(t.column)}::text = ${id}${t.ownerColumn ? sql` OR es.${sql.raw(t.ownerColumn)}::text = ${id}` : sql``} OR es.state::text LIKE ${`%${id}%`}))`,

    const entries = await readdir(join(buildDir, rel), { withFileTypes: true });

Put your own values in place of <CAELO_ADMIN_URL> (Your Caelo admin's https:// address, e.g. https://admin.example.com), <CAELO_MCP_TOKEN> (MCP token minted at /settings/mcp on your install). The author’s registry entry marks them as required.

Optional settings from the registry entry, left out of the block above: CAELO_IAP_SERVICE_ACCOUNT (Only for Google Cloud (IAP) installs; /settings/mcp shows the value).
