AI agents call federation_overrides to retrieve information from Tages without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays configuration information about memory overrides. It performs a read-only query operation that returns existing data state without creating, modifying, deleting, or executing any actions. The low severity reflects that misuse would only expose metadata about memory management decisions, with no ability to alter state or trigger external operations.
From the tool's definition The tool description states 'Show which federated memories have local project overrides' - the verb 'show' indicates a retrieval/query operation that displays information without modification.

Register the Tages MCP server in PolicyLayer and add a rule for federation_overrides: 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 Tages. Nothing to install.
federation_overrides 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 federation_overrides 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 federation_overrides. 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.
federation_overrides is provided by the Tages MCP server (ryantlee25-droid/tages). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
