Under the hood

A background 'memory pass' can now call a restricted set of tools, but only through a CCR memory server and under strict conditions

What

A new function builds a permission-check for a background task referred to as 'this background memory pass'. It only allows a tool call to proceed if all of the following hold:

  • a CCR memory MCP server is mounted for the session
  • the tool isn't blocked by an existing session permission rule
  • the tool's name appears in an allow-list
  • for tools that can write, the current conversation turn hasn't already moved on

If no CCR memory server is present, the background memory pass is blocked entirely.

Why

This lets a background process manage memory-related work using a small, controlled set of tools without opening up broader tool access, and prevents write operations from landing after the relevant turn has already ended.
