Bluecolumn Memory

🧠 BlueColumn MCP Server

Give Claude Desktop, Cursor, and any MCP-compatible agent persistent memory across sessions.

2-minute setup. Zero-config. Audio-native. Works with every MCP client.

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.

Tools

Core memory

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

Music Memory (new)

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"

Audio Intelligence

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

Streaming audio memory

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

Music Memory example

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" }

Setup

1. Get your BlueColumn API key

Sign up free at bluecolumn.ai — 60 min audio + 100 queries/month, no credit card required.

2. Install

npm install -g bluecolumn-mcp

3. Configure Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "bluecolumn": {
      "command": "bluecolumn-mcp",
      "env": {
        "BLUECOLUMN_API_KEY": "bc_live_YOUR_KEY"
      }
    }
  }
}

4. Restart Claude

Done. Claude now remembers everything you tell it to.

What Makes BlueColumn Different

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

Examples

Store project context

Remember: We're building a React component library called Aether with Tailwind CSS v4.

Recall across sessions (new conversation)

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"

Store audio notes

Record a voice memo → BlueColumn transcribes it → Claude remembers it.

Advanced

Custom namespace

{
  "mcpServers": {
    "bluecolumn": {
      "command": "bluecolumn-mcp",
      "env": {
        "BLUECOLUMN_API_KEY": "bc_live_YOUR_KEY",
        "BLUECOLUMN_NAMESPACE": "my_project"
      }
    }
  }
}

Multiple environments

Use different namespaces for work, personal, and side projects. Each stays isolated.
