AI agents call tool_lint_json to retrieve information from UltimateCoder without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Linting is a read-only operation that analyzes and reports on file contents without creating, modifying, deleting, or executing code. The tool name strongly suggests JSON validation/analysis. However, confidence is slightly reduced (0.85 rather than higher) because the description is empty and the tool could theoretically have unexpected side effects, though this is unlikely for a standard linting utility.
From the tool's definition Tool name 'tool_lint_json' indicates static analysis/validation of JSON files. Linting tools inspect code/data for style and correctness issues without modification.
Documented attack patterns abuse exactly the kind of access tool_lint_json gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and UltimateCoder, and nothing reaches the server without passing your rules. This is the rule we recommend for tool_lint_json:
{
"version": "1",
"default": "deny",
"tools": {
"tool_lint_json": {}
}
}tool_lint_json is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

tool_lint_json. It is categorised as a Read tool in the UltimateCoder MCP Server, which means it retrieves data without modifying state.
Register the UltimateCoder MCP server in PolicyLayer and add a rule for tool_lint_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 UltimateCoder. Nothing to install.
tool_lint_json 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 tool_lint_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 tool_lint_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.
tool_lint_json is provided by the UltimateCoder MCP server (m-ahmed-elbeskeri/ultimatecodermcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from UltimateCoder, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
