get_docs · CSS MCP Server MCP: Risk & Policy

WHAT IT DOES

What get_docs does on CSS MCP Server

AI agents call get_docs to retrieve information from CSS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

WHY IT NEEDS A POLICY

Why get_docs needs a policy

Based on the server's stated capability of 'MDN documentation retrieval' and the tool name 'get_docs', this appears to be a read-only operation that queries and returns documentation. It has no side effects, does not execute code, and does not modify data. The empty tool description reduces confidence slightly, but the naming convention and server context clearly indicate a retrieval operation.

From the tool's definition Tool name 'get_docs' and server description indicating 'MDN documentation retrieval' suggest this tool retrieves documentation without modifying data. No description provided for the specific tool, lowering confidence.
