adr_accept · DevFlow MCP Server MCP: Risk & Policy

WHAT IT DOES

What adr_accept does on DevFlow MCP Server

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

WHY IT NEEDS A POLICY

Why adr_accept needs a policy

This tool creates a new official ADR record by promoting a draft attachment, assigning it a number, and establishing links. It is a creation/write operation that is reversible (the ADR could be updated or revoked via adr_update_status). It does not execute code, delete data, or involve finances. The idempotency note further confirms it is a controlled write with predictable outcomes.

From the tool's definition Accept a decision.md flow-attachment as an official ADR. Auto-assigns the next ADR number for this project, copies frontmatter, links back to the flow.

Verdict

adr_accept Rate-limited

adr_accept 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.
