Update an existing museum by ID. Only include fields you want to change. Works even if do_not_import is set. Opening hours and admission prices use nested attributes (include id to update, _destroy to delete).
AI agents use update_museum to create or update resources in Confd — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Confd environment.
The tool modifies existing museum records in a reversible manner (updates can be undone by subsequent updates). It does not delete data irreversibly, execute arbitrary code, move money, or retrieve data without modification. Write operations carry medium severity due to potential for unintended data modification, but less critical than destructive or financial operations.
From the tool's definition Tool name is 'update_museum' and description states 'Update an existing museum by ID' and 'Only include fields you want to change.' This is a classic write operation that modifies existing data reversibly.
Attacks that exploit this kind of access
Update an existing museum by ID. Only include fields you want to change. Works even if do_not_import is set. Opening hours and admission prices use nested attributes (include id to update, _destroy to delete). It is categorised as a Write tool in the Confd MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Confd MCP server in PolicyLayer and add a rule for update_museum: 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 Confd. Nothing to install.
update_museum is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the update_museum 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 update_museum. 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.
update_museum is provided by the Confd MCP server (mytours/confd-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
