Return the catalog-side MoE topology for a model.
AI agents call moe_catalog_shape to retrieve information from Tenzro Ledger MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about a model's Mixture of Experts (MoE) configuration from a catalog. It performs a query operation without modifying, executing, or deleting any data. The blast radius is minimal—an AI agent misusing this tool could only obtain information about model topology, which poses no security risk. Classified as Read with low severity.
From the tool's definition Tool name 'moe_catalog_shape' and description 'Return the catalog-side MoE topology for a model' indicate a retrieval operation that queries and returns information about model configuration.

Register the Tenzro Ledger MCP server in PolicyLayer and add a rule for moe_catalog_shape: 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 Tenzro Ledger MCP. Nothing to install.
moe_catalog_shape 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 moe_catalog_shape 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 moe_catalog_shape. 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.
moe_catalog_shape is provided by the Tenzro Ledger MCP server (https://canton-mcp.tenzro.network/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
