WHAT IT DOES

What util_json_cross_field_equal does on Delx Mcp A2a

AI agents use util_json_cross_field_equal to create or update resources in Delx Mcp A2a, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Delx Mcp A2a environment.

Parameter	Type	Required	Description
`object`	object	Yes	Object supplied to JSON Cross Field Equal; used only for this bounded calculation and processed in memory without retention.
`left_field`	string	Yes	Left Field supplied to JSON Cross Field Equal; used only for this bounded calculation and processed in memory without retention.
`right_field`	string	Yes	Right Field supplied to JSON Cross Field Equal; used only for this bounded calculation and processed in memory without retention.

Parameters from the server's own tool schema.

RISK

Why util_json_cross_field_equal is rated Medium

An AI agent can call util_json_cross_field_equal faster than any human can review: one bad instruction and it creates or modifies resources in Delx Mcp A2a by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs util_json_cross_field_equal safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Delx Mcp A2a, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For util_json_cross_field_equal, this is the rule to start with:

util_json_cross_field_equal Rate-limited

util_json_cross_field_equal stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about util_json_cross_field_equal

What does the util_json_cross_field_equal tool do? +

JSON Cross Field Equal checks two top-level fields for exact JSON equality from bounded caller-supplied values without an external provider. Call JSON Cross Field Equal before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Cross Field Equal as versioned deterministic JSON. Limitation: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. It is categorised as a Write tool in the Delx Mcp A2a MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does util_json_cross_field_equal accept? +

util_json_cross_field_equal accepts 3 parameters: object, left_field, right_field. Required: object, left_field, right_field. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on util_json_cross_field_equal? +

Register the Delx Mcp A2a MCP server in PolicyLayer and add a rule for util_json_cross_field_equal: 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 Delx Mcp A2a. Nothing to install.

What risk level is util_json_cross_field_equal? +

util_json_cross_field_equal is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit util_json_cross_field_equal? +

Yes. Add a rate_limit block to the util_json_cross_field_equal 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.

How do I block util_json_cross_field_equal completely? +

Set action: deny in the PolicyLayer policy for util_json_cross_field_equal. 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.

What MCP server provides util_json_cross_field_equal? +

util_json_cross_field_equal is provided by the Delx Mcp A2a MCP server (https://api.delx.ai/v1/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
