Search for R functions in tidymodels packages
AI agents call search_r_functions to retrieve information from Tidymodels MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about available functions in tidymodels packages. It performs a search operation with no side effects, no code execution, and no data creation or deletion. It is a straightforward read operation that helps users discover available functions.
From the tool's definition Tool name is 'search_r_functions' and description states it 'Search for R functions in tidymodels packages' — a pure query/lookup operation with no data modification or execution.
Attacks that exploit this kind of access
Search for R functions in tidymodels packages. It is categorised as a Read tool in the Tidymodels MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Tidymodels MCP Server MCP server in PolicyLayer and add a rule for search_r_functions: 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 Tidymodels MCP Server. Nothing to install.
search_r_functions 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 search_r_functions 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 search_r_functions. 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.
search_r_functions is provided by the Tidymodels MCP Server MCP server (javorraca/tidymodels-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
