adr_export · Mcp Adr MCP: Risk & Policy

WHAT IT DOES

What adr_export does on Mcp Adr

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

WHY IT NEEDS A POLICY

Why adr_export needs a policy

This tool creates/writes HTML files by exporting ADR content. It is a file creation operation (Write) rather than a read, since it produces new output files. It is reversible (files can be deleted) and doesn't execute code or destroy data, so Write is the most appropriate category. Severity is medium because it could overwrite existing exported files or expose sensitive architectural decision data.

Verdict

adr_export Rate-limited

adr_export 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.
