adr_deprecate · Mcp Adr MCP: Risk & Policy

WHAT IT DOES

What adr_deprecate does on Mcp Adr

AI agents use adr_deprecate 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_deprecate needs a policy

This tool modifies existing ADR records by changing their status to deprecated, which is a reversible write operation. It does not delete data (would be Destructive), execute external code (Execute), or retrieve data (Read). The modification is non-destructive since the ADR record itself remains and the deprecation state could theoretically be reverted.

From the tool's definition Tool name 'adr_deprecate' and description 'Deprecate an ADR with a reason' indicates modification of an ADR's status/metadata. Deprecation marks a record as obsolete while preserving it (reversible state change), contrasting with deletion.
