generate_docs · MCP Server MCP: Risk & Policy

WHAT IT DOES

What generate_docs does on MCP Server

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

WHY IT NEEDS A POLICY

Why generate_docs needs a policy

This tool creates or adds documentation artifacts to a codebase, which is a reversible write operation. It does not execute code, delete data, or move money. While it modifies the codebase by adding documentation, this change is easily reversible (documentation can be regenerated or removed). The impact is limited to adding informational content without side effects on production systems or critical data.

From the tool's definition Tool generates documentation for code files ('Gera documentação para um arquivo de código'). Documentation generation creates new content (documentation files/comments) that modifies the codebase structure by adding supplementary materials.

Verdict

generate_docs Rate-limited

generate_docs stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
