get_v_module_info
AI agents call get_v_module_info to retrieve information from V Language MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool appears to retrieve information about V language modules, similar to other documentation and reference tools on the same server. The operation has no side effects—it queries module metadata or documentation without creating, modifying, or deleting data. Low severity because the blast radius of misuse is minimal: an AI agent could only retrieve information that is already public documentation.
From the tool's definition Tool name 'get_v_module_info' indicates a retrieval operation. No description provided, but context from sibling tools (get_v_documentation, get_v_example, list_v_stdlib_modules) all perform read-only documentation and reference lookups.
Attacks that exploit this kind of access
get_v_module_info. It is categorised as a Read tool in the V Language MCP Server MCP Server, which means it retrieves data without modifying state.
Register the V Language MCP Server MCP server in PolicyLayer and add a rule for get_v_module_info: 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 V Language MCP Server. Nothing to install.
get_v_module_info 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 get_v_module_info 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 get_v_module_info. 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.
get_v_module_info is provided by the V Language MCP Server MCP server (nexlab-one/python-vlang-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
