Architecture Diagrams That Stay True to the CMDB

Generate from ServiceNow, edit as canvas or code, design the future as a layer, export the change request, record the decision — and let your coding agents keep all of it current.

02 · How It Works

From CMDB Scope to Approved Change

  1. 01Step

    Connect and Pick a Scope

    OAuth to your instance, read-only. Search a business application or service; we walk cmdb_rel_ci to the depth you choose.

    • PKCE OAuth, tokens in a vault
    • Depth-bounded traversal
    • CSDM family grouping

  2. 02Step

    Edit as Canvas or Code

    The diagram is a readable DSL. Drag on the canvas or type — both edit the same text, and untouched lines never change.

    • Byte-stable comments and order
    • AI generate and AI edit
    • Conditional formatting from CMDB fields

  3. 03Step

    Design the Future as a Layer

    Add, remove, rewire on a layer over the current state. Compare shows exactly what moved, with the sys_ids behind it.

    • Change set with CI references
    • CR package: before, after, changes, description
    • ADRs tied to the layer

  4. 04Step

    Let Agents Keep It Current

    Claude Code and CI call the same typed edits through REST and MCP, with If-Match safety and an attributed audit trail.

    • Org-scoped API keys
    • 8 MCP tools
    • Every write attributed

03 · Agents

Your Coding Agent Maintains the Diagram

Connect Claude Code with one line. It reads the DSL, proposes typed edits, and commits with If-Match — a stale revision gets a 412, never a silent overwrite. Every write lands as a version attributed to the key.
