WHAT IT DOES

What getDiagramInDocument does on Stable Baseline

AI agents call getDiagramInDocument to retrieve information from Stable Baseline without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`fields`	array	—	Field projection. Valid fields: diagramId, documentId, type, name, diagramCode, nlDescription, colorPlan, renderStatus, renderError, createdAt, updatedAt, versi
`diagramId`	string	Yes	Diagram ID from DIAGRAM_OMITTED markers.

Parameters from the server's own tool schema.

RISK

Why getDiagramInDocument is rated Low

This is a straightforward data retrieval operation that queries diagram information. The mention of versionTimestamp being used as an 'optimistic-lock token for updateDiagramInDocument' is merely context for downstream writes — this tool itself only reads. No side effects, no irreversible actions, no code execution.

From the tool's definition Tool name contains 'get' and description states 'Get a diagram's full details' — retrieves diagram metadata and DSL source code with no mutations.

Risk signalsBulk/mass operation — affects multiple targets

RECOMMENDED RULE

The rule that runs getDiagramInDocument safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Stable Baseline, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For getDiagramInDocument, this is the rule to start with:

getDiagramInDocument Allowed

getDiagramInDocument is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "getDiagramInDocument": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Stable Baseline, apply this rule, and every getDiagramInDocument call is checked against it from then on.

FAQ

Questions about getDiagramInDocument

What does the getDiagramInDocument tool do? +

Get a diagram's full details including raw DSL source code. Use diagramId from DIAGRAM_OMITTED markers in getDocument output. Returns diagramCode, type, name, nlDescription, renderStatus/renderError, and versionTimestamp — the diagram's optimistic-lock token for updateDiagramInDocument (every diagram write also returns it fresh). It is categorised as a Read tool in the Stable Baseline MCP Server, which means it retrieves data without modifying state.

What parameters does getDiagramInDocument accept? +

getDiagramInDocument accepts 2 parameters: fields, diagramId. Required: diagramId. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on getDiagramInDocument? +

Register the Stable Baseline MCP server in PolicyLayer and add a rule for getDiagramInDocument: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Stable Baseline. Nothing to install.

What risk level is getDiagramInDocument? +

getDiagramInDocument is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit getDiagramInDocument? +

Yes. Add a rate_limit block to the getDiagramInDocument rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block getDiagramInDocument completely? +

Set action: deny in the PolicyLayer policy for getDiagramInDocument. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides getDiagramInDocument? +

getDiagramInDocument is provided by the Stable Baseline MCP server (https://api.stablebaseline.io/functions/v1/cloud-serve/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
