io.github.bluecolumnconsulting-lgtm/bluecolumn-memory

Persistent memory for AI agents — audio intelligence + Music Memory ingestion and recall

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package bluecolumn-mcp

Claude Code

claude mcp add bluecolumn-memory -e 'BLUECOLUMN_API_KEY=<your bluecolumn_api_key>' -e 'BLUECOLUMN_API_URL=<BLUECOLUMN_API_URL>' -- npx -y bluecolumn-mcp@1.4.0

JSON configuration (Claude Desktop, Cursor, VS Code)

{
    "mcpServers": {
        "bluecolumn-memory": {
            "command": "npx",
            "args": [
                "-y",
                "bluecolumn-mcp@1.4.0"
            ],

🧠 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

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.
