AI agents use register_function to create or modify resources in Dependencyoracle. 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 register_function 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 Dependencyoracle.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access register_function 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.
Register an ICT-supported business function — Art. 8.. It is categorised as a Write tool in the Dependencyoracle MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Dependencyoracle MCP server in PolicyLayer and add a rule for register_function: 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 Dependencyoracle. Nothing to install.
register_function 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 register_function 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 register_function. 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.
register_function is provided by the Dependencyoracle MCP server (https://tooloracle.io/dependency/mcp/). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
