About Apex Memory
Apex Memory is an MCP server published by JJerryChoi in the RAG category: persistent memory MCP server for AI coding agents. Ultra-lightweight (46 kB), cloud sync, works with Claude Code, Cursor, Windsurf. npm install apex-memory.
The repository has 2 stars and 0 forks, with the last commit 7 months ago. Six months or more without a commit doesn't mean the server is broken, but check the open issues before depending on it in production.
Install
git clone https://github.com/JJerryChoi/apex-memoryThis server has no ConduID identity, so agent calls to it are not receipted. Pin the version you install and review the source before granting it credentials.
Tools (30)
apex_memory_auto_captureAutomatically capture session context (decisions, files, errors, solutions) at session end
Parameters not published.
apex_memory_loginRegister this machine with apex-memory cloud and get a Pro upgrade link
Parameters not published.
apex_memory_statusShow cloud sync status: workspace ID, subscription tier, last sync time
Parameters not published.
apex_memory_syncManually trigger a cloud sync — push local changes and pull remote (Pro)
Parameters not published.
batch_save_memoriesSave multiple memories in a single transaction — much faster than calling save_memory repeatedly
Parameters not published.
cleanup_orphaned_linksRemove links pointing to deleted memories — keep the knowledge graph clean
Parameters not published.
decay_memoriesArchive old low-importance memories that were never accessed — keeps the store clean
Parameters not published.
delete_memoryRemove a specific memory by ID
Parameters not published.
end_sessionEnd a session with a summary of what was accomplished
Parameters not published.
export_memoriesExport all memories and sessions as JSON — useful for backup, migration, or sharing context across machines
Parameters not published.
Show all 30 tools
export_to_claudemdExport key memories as a CLAUDE.md-ready context block — inject project memory directly into your agent's instructions
Parameters not published.
find_duplicate_groupsScan for duplicate clusters using Jaccard similarity — returns groups of similar memories
Parameters not published.
find_duplicatesDetect similar existing memories using FTS5 search
Parameters not published.
get_linked_memoriesQuery the knowledge graph — find all memories connected to a given memory
Parameters not published.
import_memoriesImport memories and sessions from a JSON export — restore backups or merge context from another machine
Parameters not published.
link_memoriesCreate directional links between memories (related, depends_on, supersedes, contradicts, extends) — build a knowledge graph
Parameters not published.
list_sessionsView past coding sessions
Parameters not published.
list_tagsList all tags across memories with counts — discover how memories are organized and find tags to filter by
Parameters not published.
memory_contextGet full memory context in one call — combines relevant memories, linked memories (knowledge graph), and recent sessions
Parameters not published.
memory_graphGet the knowledge graph as nodes and edges — visualize how memories relate to each other
Parameters not published.
memory_healthDiagnose store health — stale memories, orphaned links, untagged items, cleanup candidates
Parameters not published.
memory_statsGet detailed statistics: totals, category breakdown, importance distribution, most accessed memories
Parameters not published.
memory_timelineChronological activity feed of memory events: creations, updates, sessions, and links
Parameters not published.
merge_memoriesConsolidate duplicates: keeps primary content, max importance, union tags, re-points links, soft-deletes merged
Parameters not published.
recallRetrieve recent memories filtered by project, category, or tags. Sort by `recent` or `relevant` (weighted by importance + recency + access frequency).
Parameters not published.
save_memorySave knowledge, decisions, patterns, or context with categories, tags, and importance scoring (1–5). Warns about potential duplicates automatically.
Parameters not published.
search_memoriesFull-text search across all memories (supports AND, OR, NOT, phrases). Falls back to fuzzy substring matching when FTS5 returns no results.
Parameters not published.
session_summaryReview all memories captured in a session — use at session start to restore prior context
Parameters not published.
start_sessionBegin a coding session tied to a project
Parameters not published.
update_memoryUpdate an existing memory's content, category, tags, or importance in place
Parameters not published.
