What getDiagramTypeGuide does on Stable Baseline
AI agents call getDiagramTypeGuide 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 |
|---|---|---|---|
type | string | Yes | A diagram type from listDiagramTypes (e.g. 'default', 'mermaid', 'bpmn'), or a diagram family slug or name (e.g. 'bpmn-process'), which resolves to the family's |
fields | array | — | Field projection. Valid fields: type, label, description, whenToUse, dslLanguage, dslInstructions, exampleDsl, enabled, sortOrder, updatedAt. |
Parameters from the server's own tool schema.
Why getDiagramTypeGuide is rated Low
Even though getDiagramTypeGuide only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs getDiagramTypeGuide 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 getDiagramTypeGuide, this is the rule to start with:
getDiagramTypeGuide is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Stable Baseline, apply this rule, and every getDiagramTypeGuide call is checked against it from then on.
Questions about getDiagramTypeGuide
Get DSL writing instructions and an example for a diagram type (a renderer such as 'default', 'mermaid' or 'bpmn'). Also accepts a diagram family slug or name from supportedDiagrams (e.g. 'bpmn-process'), which resolves to that family's default renderer (see resolvedFrom). supportedDiagrams lists the families the type draws, each with its defaultRenderer. Call before writing diagramCode. It is categorised as a Read tool in the Stable Baseline MCP Server, which means it retrieves data without modifying state.
getDiagramTypeGuide accepts 2 parameters: type, fields. Required: type. The full parameter table on this page comes from the server's own tool schema.
Register the Stable Baseline MCP server in PolicyLayer and add a rule for getDiagramTypeGuide: 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.
getDiagramTypeGuide is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the getDiagramTypeGuide 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.
Set action: deny in the PolicyLayer policy for getDiagramTypeGuide. 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.
getDiagramTypeGuide 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.
