get_model_diagram
AI agents call get_model_diagram to retrieve information from Orionbelt Semantic Layer without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool appears to retrieve or render a visual diagram representation of a semantic model without modifying data. No side effects, no deletion, no code execution, and no financial implications are indicated. The 'get_' prefix and peer tools confirm read-only classification. Low severity due to limited blast radius—viewing a model diagram cannot alter systems or data.
From the tool's definition Tool name is 'get_model_diagram', which indicates retrieval of visual metadata about a model. The function verb 'get' implies a read-only query operation.
Attacks that exploit this kind of access
get_model_diagram. It is categorised as a Read tool in the Orionbelt Semantic Layer MCP Server, which means it retrieves data without modifying state.
Register the Orionbelt Semantic Layer MCP server in PolicyLayer and add a rule for get_model_diagram: 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 Orionbelt Semantic Layer. Nothing to install.
get_model_diagram 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 get_model_diagram 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 get_model_diagram. 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.
get_model_diagram is provided by the Orionbelt Semantic Layer MCP server (ralfbecher/orionbelt-semantic-layer-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
