WHAT IT DOES

What yaml_json_convert does on Gateway

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

Parameter	Type	Required	Description
`data`	object	—	JSON object to serialize (direction=json_to_yaml)
`yaml`	string	—	YAML text (direction=yaml_to_json)
`direction`	string	Yes	yaml_to_json \| json_to_yaml

Parameters from the server's own tool schema.

RISK

Why yaml_json_convert is rated Medium

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

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs yaml_json_convert safely

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

yaml_json_convert Rate-limited

yaml_json_convert 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.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "yaml_json_convert": {
      "limits": [
        {
          "counter": "yaml_json_convert_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

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

FAQ

Questions about yaml_json_convert

What does the yaml_json_convert tool do? +

YAML <-> JSON Converter — Convert a YAML document to JSON, or a JSON object to YAML, using a safe (non-code-executing) parser. It is categorised as a Write tool in the Gateway MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does yaml_json_convert accept? +

yaml_json_convert accepts 3 parameters: data, yaml, direction. Required: direction. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on yaml_json_convert? +

Register the Gateway MCP server in PolicyLayer and add a rule for yaml_json_convert: 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 Gateway. Nothing to install.

What risk level is yaml_json_convert? +

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

Can I rate-limit yaml_json_convert? +

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

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

yaml_json_convert is provided by the Gateway MCP server (https://wingmanprotocol.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
