Multi-platform AI memory. One save, recall everywhere—Claude, ChatGPT, Cursor, and more. The memxus mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 14 defined tools rather than through you.
Memxus brings Context Engineering to your entire AI workflow.
Memxus is a Context Engineering designed to multiply your productivity by giving every AI the right context.
Everything the assistant can do here goes through one of these:
remember — Save context — manual input, decisions, or notes; optional project: collectionrecall — Semantic search across memories; GitHub/Notion synced content via project: or tagsget_context — Formatted context block from GitHub, Notion, and saved decisions for agent promptslist_memories — Browse memories by collection, tags, type, or visibilityget_memory — Retrieve full content and metadata by memory IDlist_collections — List scopes; GitHub/Notion syncs appear under project:forget — Delete a memory permanentlymemory_stats — Stats by type and collectionupdate — Patch or append existing memory content, tags, or typeconnect_source — Start GitHub App install or Notion OAuth from chatlist_syncable_items — List repos or Notion pages available after connectingset_sync_selection — Choose what to sync and trigger initial sync into project:Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
You will need 6 environment variables: MCP_PUBLIC_URL, DASHBOARD_URL, SUPABASE_URL, SUPABASE_SERVICE_ROLE_KEY, OAUTH_CLIENT_ID, OPENAI_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Memxus's toolset — remember, recall, get_context and 11 more — is a fair guide to whether it matches your workflow. It is maintained by com.memxus; worth a glance at recent repository activity before you build anything load-bearing on it.

A knowledge graph your assistant keeps between sessions — entities, relations and observations that persist.
Kill hallucinated APIs — version-accurate, up-to-date library documentation injected straight into context.
Your workspace, on speaking terms with AI — search, read and write Notion pages and databases.
A structured scratchpad for hard problems — stepwise reasoning with revisions, branches and visible logic.
Symbol-level code navigation, refactoring and memory for coding agents — the IDE brain your assistant has been missing.
Chat with your second brain — search, read and write vault notes through the Local REST API.
