AI agents call list_languages to retrieve information from Tgstat without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves a static list of supported language codes from the TGStat API. It performs a query-only operation that neither modifies data nor triggers external actions. The blast radius is minimal—misuse by an AI agent would only result in retrieving language codes, which cannot harm data or systems.
From the tool's definition Tool name 'list_languages' and description 'List available language codes' indicate a simple data retrieval operation with no side effects or modifications.

Register the Tgstat MCP server in PolicyLayer and add a rule for list_languages: 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 Tgstat. Nothing to install.
list_languages 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 list_languages 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 list_languages. 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.
list_languages is provided by the Tgstat MCP server (theyahia/tgstat-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
