Description from the maker (original English)
Persistent memory for AI agents — audio intelligence + Music Memory ingestion and recall
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
Pick the AI app you use, then copy the settings.

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
The GitHub repo last changed –, and the latest version (1.4.0) reached the registry 2 months ago.

MCP server for BlueColumn — persistent semantic memory for AI agents.
Give any MCP-compatible agent (Claude Desktop, Cursor, Windsurf, LangChain, AutoGen, CrewAI) the ability to remember, recall, and store observations across sessions.
| Tool | Description |
|---|---|
remember | Ingest text, audio, or documents into persistent memory |
recall | Query memory with natural language, get AI-synthesized answer + sources |
note | Store lightweight agent observations as searchable vectors |
namespace | Show the configured namespace |
| Tool | Description |
|---|---|
music_remember | Store a musical recording, practice session, or lesson with rich musical context — instrument, key, tempo, technique tags, chord progression, notes. Audio is transcribed; the structured context is embedded alongside so a coach/teacher agent recalls it with full musical understanding |
music_recall | Search stored musical content with musical filters — instrument, technique, or style. E.g. "show me every take with barre chord issues" or "what did we practice in E minor last month" |
| Tool | Description |
|---|---|
audio_ingest | Ingest calls, voice notes, podcasts, meetings, or music and extract semantic memory |
audio_recall | Search audio memories and get audio-backed citations |
call_prepare | Get memory context before a voice call starts |
call_complete | Store what changed after a call ends |
sound_analyze | Detect and index non-speech audio events |
music_analyze | Extract tempo, structure, instrumentation, mood from music |
| Tool | Description |
|---|---|
streaming_audio_ingest | Ingest edge-device audio chunks (car, doorbell, wearable) into per-device streaming memory |
streaming_audio_recall | Recall over a device's streamed audio history |
Store a practice session:
music_remember {
"audio_url": "https://example.com/take3.mp3", "title": "Week 3 practice — barre chords, Sep 7", "instrument": "guitar", "musical_key": "E minor", "tempo_bpm": 92, "technique_tags": ["barre-chords", "hammer-on"], "style_tags": ["blues"], "chord_progression": ["Em", "Am", "B7"], "notes": "F-shape barre still buzzy on the B string; Fmaj7 subst worked well" }
Then recall it musically:
music_recall { "q": "which takes had barre chord issues?", "instrument": "guitar" }

npm install -g bluecolumn-mcp
Add to ~/Library/Application Support/Claude/claude_desktop_config.json:
{
"mcpServers": { "bluecolumn": { "command": "bluecolumn-mcp", "env": { "BLUECOLUMN_API_KEY": "bc_live_YOUR_KEY" } } } }
Done. Claude now remembers everything you tell it to.
| Feature | BlueColumn MCP | Other MCP Memory Servers |
|---|---|---|
| Audio ingestion | ✅ Native (transcribe + store) | ❌ Text only |
| Plain English recall | ✅ "What did we decide about pricing?" | ❌ Keyword/vector only |
| Setup time | ~2 minutes | ~10-30 minutes |
| Cloud managed | ✅ No infra to run | ⚠️ Most require local DB |
| Namespace isolation | ✅ Built-in per key | ⚠️ Manual |
Remember: We're building a React component library called Aether with Tailwind CSS v4.
What project was I working on? What was my tech stack?
→ *Claude recalls: "You're building Aether, a React component library with Tailwind CSS v4"*
Record a voice memo → BlueColumn transcribes it → Claude remembers it.
{
"mcpServers": { "bluecolumn": { "command": "bluecolumn-mcp", "env": { "BLUECOLUMN_API_KEY": "bc_live_YOUR_KEY", "BLUECOLUMN_NAMESPACE": "my_project" } } } }
Use different namespaces for work, personal, and side projects. Each stays isolated.
