Get the latest version of a Maven Central artifact.
AI agents call get_maven_artifact 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 performs a package registry query to fetch metadata about Maven artifacts—specifically version information and related metadata. It has no side effects; it does not execute code, modify data, delete data, or commit financial transactions. It is purely informational, similar to a search or fetch operation against a public package repository.
From the tool's definition Tool queries package metadata from Maven Central registry. The name uses 'get' and description states 'retrieve the latest version', indicating a read-only retrieval operation with no modification, deletion, or execution of code.

Get the latest version of a Maven Central artifact. 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_maven_artifact: 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_maven_artifact 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_maven_artifact 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_maven_artifact. 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_maven_artifact 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.
