Restructure JSON data from one schema to another using dot-notation path mapping. Maps fields from the source to new positions in the target. Handles both single objects and arrays of objects. Example: mapping={'full_name': 'user.profile.name', 'email': 'user.contact.email'} extracts nested value...

AI agents invoke reshape_json to trigger processes or run actions in Data Converter. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
reshape_json can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

These attack patterns abuse exactly the kind of access reshape_json gives an agent. Each links to the full case and the policy that stops it:
Other execute tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Restructure JSON data from one schema to another using dot-notation path mapping. Maps fields from the source to new positions in the target. Handles both single objects and arrays of objects. Example: mapping={'full_name': 'user.profile.name', 'email': 'user.contact.email'} extracts nested values into a flat structure.. It is categorised as a Execute tool in the Data Converter MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Data Converter MCP server in PolicyLayer and add a rule for reshape_json: 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 Data Converter. Nothing to install.
reshape_json is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the reshape_json 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 reshape_json. 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.
reshape_json is provided by the Data Converter MCP server (data-transform-agent/data-transform). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
