The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond.
Codex Dev MCP Suite
Four local, file-based MCP servers for solo devs/vibecoders: persistent memory, session handoff/resume, file checkpoints, token-efficient project briefings. Works with any MCP…

😩 Sound Familiar?
"You spent 45 minutes explaining your database schema and architecture to your AI agent. Then... 'Context window compacted' or session restarted. Boom. Your AI forgot everything and started hallucinating variable names."
Stop re-pasting context over and over.
Dev MCP Suite is a suite of four local, zero-telemetry MCP (Model Context Protocol) servers built for solo developers and vibe coders. It equips your favorite AI agent (Codex CLI, Hermes Agent, Google Antigravity, Claude Code, Cursor, Windsurf) with permanent memory, anti-compaction handoffs, git-safe checkpoints, and offline vector search.
⚡ Before & After Dev MCP Suite
| Without Dev MCP Suite 🥱 | With Dev MCP Suite ⚡ |
|---|---|
| Re-explaining project setup every time session resets | One-command journal_resume recovers context instantly |
| AI forgets architectural decisions and preferences | Obsidian-compatible Markdown vault retains knowledge permanently |
| Wasted git commits just to save temporary experiments | Git-independent checkpoint_create & instant rollback |
| Accidental secret/API key leaks committed to GitHub | Built-in pack_audit flags missing .gitignore & leaked keys |
| Locked into a proprietary hosted backend | 100% Local-first, zero cloud lock-in, zero telemetry |
⚡ 10-Second Quickstart
Automatically configure all installed AI tools (Codex CLI, Claude Code, Cursor, Windsurf, Hermes, Antigravity) with 1 command:
npx -y codex-dev-mcp-suite init
Or test a single server right now without installing:
npx -y -p codex-dev-mcp-suite project-memory-mcp --help
🛠️ The 4 Superpowers (MCP Servers)
| Server | Superpower | Key Tools |
|---|---|---|
🧠 project-memory |
Obsidian-Grade Knowledge Vault: Persistent Markdown notes, wiki-links ([[note]]), MOC generation, zero-dependency local 384-d vector search (MCP_LOCAL_EMBED=true), multi-agent swarm stream, and autonomous background git observer (memory_auto_index). |
memory_save, memory_recall, memory_list, memory_get, memory_link, memory_moc, memory_graph, memory_dedup, memory_broadcast, memory_swarm_timeline, memory_auto_index |
📜 devjournal |
Anti-Compaction Session Timeline: Logs progress, saves handoffs, restores full context, and compresses session logs to cut token costs ~90%. | journal_log, journal_handoff, journal_resume, journal_timeline, journal_search, journal_compress, journal_clear_handoff |
🛡️ checkpoint |
Git-Independent Snapshots: Take 1-second file snapshots before risky AI refactors. Compare diffs and revert instantly without touching your git tree. | checkpoint_create, checkpoint_list, checkpoint_diff, checkpoint_restore, checkpoint_delete |
🔍 context-pack |
Autonomous Agent OS: Token-efficient briefings, dependency blast-radius analysis (pack_impact), self-healing preflight checks (pack_guard), live log telemetry (pack_telemetry), predictive contract diff simulation (pack_predictive_diff), and security auditing (pack_audit). |
pack_overview, pack_tree, pack_outline, pack_search, pack_audit, pack_impact, pack_guard, pack_telemetry, pack_predictive_diff |
🧠 Intelligent Local-First Semantic Search
