What it can do

  • Omega Store: Store a memory with optional type and metadata. Use when the user says 'remember this' or for programmatic capture (decisions, lessons, errors). Defaults to type 'memory' if event_type is
  • Omega Query: Search memories — semantic (default) or exact phrase match. Use mode='phrase' for literal substring search (error messages, specific strings).
  • Omega Welcome: Get a session welcome briefing with recent relevant memories and user profile.

What data it sees

Do you need an account

No: the server works without sign-in

Persistent memory for AI coding agents. Store decisions, lessons, error patterns, and task checkpoints, then retrieve them via semantic search or graph traversal. Features session briefings, memory consolidation, time-based reminders, encrypted profiles, and knowledge compaction. Works with Claude Code, Cursor, Windsurf, VS Code, and any MCP-compatible client. #1 on LongMemEval benchmark (95.4%). Install: pip install omega-memory && omega setup

How to connect

How to connect OMEGA Memory to Claude

The server address to paste into Claude settings:

https://core--omega-memory.run.tools

  1. Open Claude (claude.ai or the desktop app).
  2. Go to Settings → Connectors.
  3. Click Add custom connector.
  4. Paste the server address copied below into Remote MCP server URL and click Add.
  5. In a chat, click + → Connectors and switch the new connector on.

Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

Authorization

After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

How to connect OMEGA Memory to ChatGPT

The server address to paste into ChatGPT settings:

https://core--omega-memory.run.tools

  1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
  2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
  3. Open Settings → Connectors and click Create.
  4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
  5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
  6. In a new chat open + → Apps/Connectors and enable the connector.

OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

Authorization

On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

How to connect OMEGA Memory to Cursor

The server address to paste into Cursor settings:

https://core--omega-memory.run.tools

Fastest: click Open in Cursor below and confirm the prompt.

Manually:

  1. In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
  2. Paste the JSON copied below into ~/.cursor/mcp.json (per project: .cursor/mcp.json in the repo root).
  3. Save the file. The server appears in the MCP list; authorize it there if asked.

Authorization

If the service needs sign-in, an authorize button appears next to the server in the MCP list.

Server tool list (26)

Raw names from tools/list. Only developers need these.

omega_storeStore a memory with optional type and metadata. Use when the user says 'remember this' or for programmatic capture (decisions, lessons, errors). Defaults to type 'memory' if event_type is omitted.
omega_querySearch memories — semantic (default) or exact phrase match. Use mode='phrase' for literal substring search (error messages, specific strings).
omega_welcomeGet a session welcome briefing with recent relevant memories and user profile.
omega_profileRead or update the user profile. Returns the profile by default. If 'update' dict is provided, merges those fields into the profile and saves.
omega_delete_memoryDelete a specific memory by its ID.
omega_edit_memoryEdit the content of a specific memory.
omega_list_preferencesList all stored user preferences.
omega_healthDetailed health check with memory usage, node counts, cache stats, warnings, and recommendations.
omega_backupExport or import memories for backup/restore. Default mode is export.
omega_lessonsRetrieve cross-session or cross-project lessons learned, ranked by verification count and access frequency.
omega_feedbackRecord feedback on a surfaced memory (helpful, unhelpful, outdated). Improves future surfacing quality.
omega_clear_sessionClear all memories for a specific session. Use for cleanup after test sessions.
omega_similarFind memories similar to a given memory. Use for discovering related context.
omega_timelineShow memory timeline grouped by day. Use to see what was captured recently.
omega_consolidateRun memory consolidation: prune stale low-value memories, cap session summaries, clean orphaned edges. Returns a report.
omega_traverseTraverse the memory relationship graph from a starting memory. Shows all connected memories within N hops, useful for understanding context chains and discovering related knowledge clusters.
omega_compactCompact related memories into consolidated knowledge nodes. Finds clusters of similar memories (same event type, high overlap) and creates summary nodes, marking originals as superseded. Reduces noise while preserving knowledge.
omega_checkpointSave a task checkpoint — captures current plan, progress, files touched, decisions, and key context. Use when: (1) context window is getting full, (2) completing a major milestone, (3) before starting a new session for an ongoing task. Checkpoints enable seamless session continuity.
omega_resume_taskResume a previously checkpointed task. Retrieves the latest checkpoint with full plan, progress, files, decisions, and next steps. Use at the start of a new session to continue where you left off.
omega_remindSet a time-based reminder. OMEGA will surface it when the time arrives (at session start or during active sessions). Use for 'remind me in 1 hour to...' requests.
omega_remind_listList active reminders with their status and due times.
omega_remind_dismissDismiss a reminder by its ID. Use after acknowledging a reminder.
omega_type_statsGet memory counts grouped by event type. Shows the composition of the memory store (how many decisions, lessons, errors, etc.).
omega_session_statsGet memory counts grouped by session. Shows which sessions have contributed the most memories (top 20).
omega_weekly_digestGet a weekly knowledge digest with stats, trends, and highlights. Shows new memories, session count, growth trends, type breakdown, and top topics.
omega_protocolGet your coordination playbook — dynamically assembled operating instructions. Call at session start (step 2 after omega_welcome) or when you need protocol guidance. Returns context-sensitive rules based on project, peer activity, and learned lessons.
