build_r_snippet · OpenLandMap MCP Server MCP: Risk & Policy

WHAT IT DOES

What build_r_snippet does on OpenLandMap MCP Server

AI agents invoke build_r_snippet to trigger actions in OpenLandMap MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why build_r_snippet needs a policy

Based on the sibling tool 'build_python_snippet' and the naming pattern, this tool likely generates R code snippets for data access. Code generation tools can be Execute category if they run code, but may only be Write if they just produce a snippet. The empty description lowers confidence significantly.

From the tool's definition Tool name 'build_r_snippet' and sibling tool 'build_python_snippet' suggest code generation/execution. Description is empty, providing no additional context.
