v0.4.1 — Memory Context & Fuzzy Search

What's New

• memory_context tool — get relevant memories, linked memories (knowledge graph), and recent sessions in a single call
• Fuzzy search fallback — search_memories now falls back to LIKE-based substring matching when FTS5 returns no results

Stats

• 24 tools, 5 resources, 3 prompts
• 436 tests passing
• 35 kB package size

v0.4.0 — Memory Linking & Dedup Detection

What's New

Memory Linking — Knowledge Graph

• link_memories — Create directional links between memories with 5 link types: related, depends_on, supersedes, contradicts, extends
• get_linked_memories — Query the knowledge graph — find all connected memories (bidirectional traversal)
• New memory_links table with composite primary key and foreign keys

Deduplication Detection

• find_duplicates — Detect similar existing memories using FTS5 search
• find_duplicate_groups — Scan for duplicate clusters using Jaccard similarity
• merge_memories — Consolidate duplicates: keeps primary content, max importance, union tags, re-points links, soft-deletes merged
• save_memory enhanced — Now warns about potential duplicates automatically on save

Stats

• 23 tools (up from 18)
• 342 tests (up from 284)

v0.3.3 — export_to_claudemd + CI release workflow

What's New

Added

• export_to_claudemd tool — Export top project memories as a markdown section for CLAUDE.md or project instruction files. Bridges MCP and non-MCP editors so any agent can access stored context.
• CI release workflow — Automated npm publish on git tag push via .github/workflows/release.yml

v0.3.2 — Smart recall, export/import, update_memory

What's New in v0.3.2

17 tools | 266 tests | 25 kB package

Smart Recall (new in v0.3.2)

• recall tool now accepts sort parameter:
  • "recent" — default, backwards-compatible (created_at DESC)
  • "relevant" — weighted score: importance (40%) + recency (40%) + access frequency (20%)

New Tools (v0.3.1+)

• update_memory — update content, category, tags, or importance of existing memories in place
• export_memories — export all memories and sessions as JSON for backup or migration
• import_memories — import from JSON, skips duplicates by ID

MCP Resources & Prompts (v0.3.1+)

• 5 browseable MCP resources — memories visible in editor sidebars
• 3 MCP prompts — guided workflows for common memory tasks

Bug Fixes

• Tag matching in recall now uses exact boundary matching ("test" no longer matches "testing")
• GitHub URLs corrected across docs and landing page

v0.3.1 — update_memory, tag fix, MCP resources/prompts

What's New

New Tool: update_memory

Update content, category, tags, or importance of existing memories in place — no more delete + re-save.

update_memory({ id: "...", content: "revised content", importance: 5 })

Bug Fix: Tag Matching Precision

recall tag filter now uses exact boundary matching. Previously "test" would incorrectly match "testing". Fixed with (',' || tags || ',' LIKE '%,tag,%') pattern.

MCP Resources & Prompts

5 browseable resources and 3 prompts registered. Memories are now visible in editor sidebars (VS Code, Cursor, etc.) that support MCP resource browsing.

VS Code + GitHub Copilot Guide

New integration guide for VS Code + GitHub Copilot setup added to docs.

apex-memory v0.2.1 — Persistent memory for AI coding agents

apex-memory v0.2.1

Persistent memory for AI coding agents — MCP server, SQLite, one command install.

Your AI coding agent now remembers across sessions: architecture decisions, bug patterns,
user preferences, project context. No more re-explaining everything at the start of each session.

Install

Claude Code:

claude mcp add apex-memory -- npx apex-memory

Cursor / any MCP client — add to your MCP config:

{
  "mcpServers": {
    "apex-memory": { "command": "npx", "args": ["apex-memory"] }
  }
}

9 tools added to your agent

Tool	Description
save_memory	Save decisions, bugs, patterns, architecture with categories and tags
search_memories	Full-text search across all memories (FTS5: AND, OR, NOT, phrases)
recall	Retrieve recent memories filtered by project, category, or tag
delete_memory	Remove a memory by ID
decay_memories	Archive old low-importance memories to keep the store clean
start_session	Begin a coding session tied to a project
end_session	End a session with a summary
list_sessions	View past sessions
memory_stats	Stats on stored memories and active projects

What's new in v0.2.1

• Billing integration updated to Lemon Squeezy for Pro and Team tier subscriptions

What's new since v0.1.0

• importance scoring (1–5) on save_memory — rank how critical a memory is
• Access tracking — last_accessed_at updated on every recall or search hit
• decay_memories tool — archive old low-importance memories that haven't been accessed
• memory_stats now shows total memory count per category and session count

Storage

All data stored locally at ~/.apex-memory/memory.db — SQLite with WAL mode and FTS5
full-text search. No cloud. No accounts. No data leaves your machine.

Memory categories

decision · architecture · bug · pattern · preference · learning · context · general

Compatibility

• Claude Code (native claude mcp add install)
• Cursor (.cursor/mcp.json)
• Windsurf (~/.codeium/windsurf/mcp_config.json)
• Any MCP-compatible editor via npx apex-memory

What's next
