WHAT IT DOES

What json_patch does on ScorpTech x402 API

AI agents use json_patch to create or update resources in ScorpTech x402 API, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ScorpTech x402 API environment.

Parameter	Type	Required	Description
`mode`	string	—
`patch`	object	Yes	RFC 6902 operations array, or an object = RFC 7386 merge patch
`document`	object	Yes	Target JSON value

Parameters from the server's own tool schema.

RISK

Why json_patch is rated Medium

An AI agent can call json_patch faster than any human can review: one bad instruction and it creates or modifies resources in ScorpTech x402 API by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs json_patch safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ScorpTech x402 API, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For json_patch, this is the rule to start with:

json_patch Rate-limited

json_patch 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.

          "window": "minute",
          "max": 30,

        }
      ]
    }
  }
}

The button opens the PolicyLayer dashboard: create your workspace, connect ScorpTech x402 API, apply this rule, and every json_patch call is checked against it from then on.

FAQ

Questions about json_patch

What does the json_patch tool do? +

Apply a JSON Patch (RFC 6902: add, remove, replace, move, copy, test) or a JSON Merge Patch (RFC 7386) to a JSON document and return the result. Atomic: any failing operation or test returns 422 with the operation index and nothing is applied. POST JSON body {document, patch}. Price: $0.002 USDC per successful call (x402, Solana). Same tool over HTTPS: POST https://scorptech.it.com/api/x402/v1/json-patch. It is categorised as a Write tool in the ScorpTech x402 API MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does json_patch accept? +

json_patch accepts 3 parameters: mode, patch, document. Required: patch, document. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on json_patch? +

Register the ScorpTech x402 API MCP server in PolicyLayer and add a rule for json_patch: 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 ScorpTech x402 API. Nothing to install.

What risk level is json_patch? +

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

Can I rate-limit json_patch? +

Yes. Add a rate_limit block to the json_patch 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 json_patch completely? +

Set action: deny in the PolicyLayer policy for json_patch. 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 json_patch? +

json_patch is provided by the ScorpTech x402 API MCP server (https://scorptech.it.com/api/x402/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
