Compare every locale against the base locale (${baseCode}, the first one loaded).
AI agents call diff to retrieve information from Mcp Locator without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The diff tool retrieves and compares locale translation files but does not create, modify, delete, or execute code. It is a straightforward read operation that analyzes differences between locale files. The low severity reflects minimal blast radius — a misused diff cannot corrupt or delete data, only return potentially verbose or misleading comparison output.
From the tool's definition Tool description states 'Compare every locale' — a comparison operation that reads and analyzes data without modification. The function performs a read-only diff operation against existing locale data.

Attacks that exploit this kind of access
Compare every locale against the base locale (${baseCode}, the first one loaded). It is categorised as a Read tool in the Mcp Locator MCP Server, which means it retrieves data without modifying state.
Register the Mcp Locator MCP server in PolicyLayer and add a rule for diff: 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 Mcp Locator. Nothing to install.
diff 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 diff 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 diff. 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.
diff is provided by the Mcp Locator MCP server (tankonyako/mcp-locator). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
