What validate_json_params does on Cocos
AI agents call validate_json_params to retrieve information from Cocos without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why validate_json_params is rated Low
This is a utility tool that checks JSON data structure and syntax. Validation is a read-only operation that examines input without executing external commands, modifying assets, or triggering editor operations. It serves as a preprocessor to ensure data integrity before downstream tools consume the parameters. No data is created, deleted, or executed as a result of calling this tool itself.
From the tool's definition Tool name 'validate_json_params' and description 'Validate and fix JSON parameters before sending to other tools' indicate inspection and validation without modification or side effects.
Attacks that exploit this kind of access
The rule that runs validate_json_params safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Cocos, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For validate_json_params, this is the rule to start with:
validate_json_params is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Cocos, apply this rule, and every validate_json_params call is checked against it from then on.
Questions about validate_json_params
Validate and fix JSON parameters before sending to other tools. It is categorised as a Read tool in the Cocos MCP Server, which means it retrieves data without modifying state.
Register the Cocos MCP server in PolicyLayer and add a rule for validate_json_params: 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 Cocos. Nothing to install.
validate_json_params is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the validate_json_params 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 validate_json_params. 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.
validate_json_params is provided by the Cocos MCP server (caravanglory/cocos-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
