export_scss · MCP Color Server MCP: Risk & Policy

WHAT IT DOES

What export_scss does on MCP Color Server

AI agents use export_scss to create or update resources in MCP Color Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP Color Server environment.

WHY IT NEEDS A POLICY

Why export_scss needs a policy

export_scss creates formatted code artifacts (SCSS variables and maps) from color data. This is a reversible write operation—generating code files or strings that can be easily modified or discarded. No data is irreversibly deleted, no arbitrary code is executed, and no financial transactions occur.

From the tool's definition Tool generates SCSS variables, maps, and mixins - it creates/modifies code output (Write category). The description indicates output generation rather than data deletion or execution of arbitrary commands.
