Get the latest version of an R package from CRAN.
AI agents call get_r_package 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 remote package registry (CRAN) and returns version information and metadata about an R package. It performs no data modification, deletion, code execution, or financial transaction. The operation is read-only and side-effect free, making it a straightforward Read category tool with low severity.
From the tool's definition Tool name 'get_r_package' and description 'Get the latest version of an R package from CRAN' indicate a retrieval/query operation with no modification of data.

Register the Versionator MCP server in PolicyLayer and add a rule for get_r_package: 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_r_package 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_r_package 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_r_package. 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_r_package 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.
