AI agents use agda_backend_top to create or modify resources in Agda. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call agda_backend_top repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Agda.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access agda_backend_top gives an agent. Each links to the full case and the policy that stops it:
Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Send a backend-specific top-level payload via Cmd_backend_top.. It is categorised as a Write tool in the Agda MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Agda MCP server in PolicyLayer and add a rule for agda_backend_top: 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 Agda. Nothing to install.
agda_backend_top 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 agda_backend_top 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 agda_backend_top. 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.
agda_backend_top is provided by the Agda MCP server (agda-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
