Get the latest version of a Go module.
AI agents call get_go_module to retrieve information from Versionator without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries a package registry (Go modules) to fetch version information and metadata. It is a read-only operation with no side effects, no code execution, no data modification, and no financial impact. The blast radius of misuse is minimal—an agent could only retrieve publicly available package information.
From the tool's definition Tool name 'get_go_module' and description 'Get the latest version of a Go module' indicate a query operation that retrieves package metadata from a registry without modifying or executing anything.
Attacks that exploit this kind of access
Get the latest version of a Go module. It is categorised as a Read tool in the Versionator MCP Server, which means it retrieves data without modifying state.
Register the Versionator MCP server in PolicyLayer and add a rule for get_go_module: 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 Versionator. Nothing to install.
get_go_module 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_go_module 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_go_module. 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_go_module is provided by the Versionator MCP server (trianglegrrl/versionator-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
