RememBLOCK
Local-first persistent memory for Claude Code & Codex CLI - Rust CLI, hooks, MCP server, SQLite/SQLCipher, auditable recall for long-running coding work.
Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

Stop re-explaining your project every new coding-agent session.
Language: English | 简体中文
remem automatically captures, distills, searches, and injects engineering memory across Claude Code and OpenAI Codex CLI sessions. Decisions, bug-fix rationale, project patterns, and preferences stay available through hooks, MCP, CLI, and a localhost REST API.

A new Claude Code session recalls the earlier root cause, commit, and open TODO with memory citations and no re-explaining.
What remem gives you
- Automatic session capture and background LLM distillation.
- Project-scoped recall across Claude Code and Codex using one local store.
- Searchable decisions, bug fixes, architecture notes, preferences, and raw
session evidence.
- Source attribution, staleness labels, suppression, review queues, and
injection audits.
- SQLite with SQLCipher encryption by default for fresh installs.
- MCP, CLI, and authenticated localhost REST access from one Rust runtime.
remem prioritizes memory quality. Automatic capture is the primary path; manual save_memory calls supplement it when a decision needs to b

Questions
What is the Remem MCP server?
Local-first persistent memory for Claude Code & Codex CLI - Rust CLI, hooks, MCP server, SQLite/SQLCipher, auditable recall for long-running coding work.
What tools does Remem expose?
13 in total: 7 read-only, 5 that write, and 1 that can delete or overwrite (remem_governance_preview). Every one is listed on this page with its risk.
Is Remem safe to connect to an agent?
No — not without reading the findings first. The audit graded it F (24/100) and found 11 critical or high issues in the source. Each one is listed on this page with the file and line it is on. Separately from the audit: 1 of its tools can destroy data, so scope the token you give it to what you actually need.
What credentials does Remem need?
It reads OPENAI_API_KEY, REMEM_API_TOKEN and REMEM_API_TOKEN_FILE from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does Remem run?
It speaks stdio, so it runs as a local process your client starts. It is published on npm as @remem-ai/remem at 0.6.104.
How current is this page?
The grade is for one exact copy of the source (51165e7def80), read on 2026-10-09. The repository is watched and re-audited when it changes.
