link_commit · Framedeck MCP: Risk & Policy

WHAT IT DOES

What link_commit does on Framedeck

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

WHY IT NEEDS A POLICY

Why link_commit needs a policy

This tool modifies card state by adding a link and automatically creating a comment. It is a write operation that changes card metadata and adds data reversibly. It does not execute code, delete data, or move money. While it references git commits (external state), it does not execute git commands or checkout code—it merely associates existing commit information with a card for tracking purposes.

From the tool's definition "Link a git commit to a card. Automatically adds commit info as a comment." — creates a link between a git commit and a card, and adds a comment automatically.

Verdict

link_commit Rate-limited

link_commit 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.
