update_tech_stack · Coord MCP: Risk & Policy

WHAT IT DOES

What update_tech_stack does on CoordMCP

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

WHY IT NEEDS A POLICY

Why update_tech_stack needs a policy

The tool performs a reversible modification to project configuration (Write category). Severity is medium because misconfiguration of tech stack by an AI agent could impact development workflow and require correction, but would not cause irreversible data loss or financial impact. Confidence is 0.85 (not higher) because the description is empty, requiring inference from the tool name and server context alone.

From the tool's definition Tool name 'update_tech_stack' indicates modification of project technical stack configuration. Within a coordination server managing shared project state, updating tech stack would create or modify project metadata reversibly.
