Codex memory
Give Codex memory that survives the task.
Register MADB once. Codex gains local tools for durable recall, causal lineage, skills, export and temporal validity.
Install
Add the local MCP server
codex mcp add madb -- uvx madb-mcp-serverRestart or open a new task after registration.
Verify
Prove cross-task recall
- Ask Codex to remember one real project decision and its cause.
- Open a new task.
- Ask what it remembers and why.
- Confirm the answer used
recallandtrace_cause.
The server provides tools; the skill provides the reflex.
When the MADB memory skill is present, Codex prefers MADB for durable cross-session state. Installation still requires user approval.
