manage_patterns · PromptForge MCP Server MCP: Risk & Policy

WHAT IT DOES

What manage_patterns does on PromptForge MCP Server

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

WHY IT NEEDS A POLICY

Why manage_patterns needs a policy

The tool modifies a patterns library, which is reversible data creation/modification (Write category). Severity is medium because corrupted or malicious patterns could degrade AI outputs across multiple domains (marketing, analysis, tax, code generation), but the effects are not irreversible (Destructive) nor do they move money (Financial) nor execute arbitrary code directly (Execute).

From the tool's definition Tool name 'manage_patterns' combined with description 'Manages the prompt optimization patterns library' indicates create/update/modify operations on stored patterns.

What risk level is manage_patterns? +

manage_patterns is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit manage_patterns? +
