Overview

Description from the maker (original English)

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

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Search & AI memory
  • You need to fill in: BLUECOLUMN_API_KEY

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: BLUECOLUMN_API_KEY, BLUECOLUMN_API_URL

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "bluecolumn-memory": {
      "command": "npx",
      "args": [
        "-y",
        "bluecolumn-mcp"
      ],
      "env": {
        "BLUECOLUMN_API_KEY": "your-value",
        "BLUECOLUMN_API_URL": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add bluecolumn-memory --env BLUECOLUMN_API_KEY=your-value --env BLUECOLUMN_API_URL=your-value -- npx -y bluecolumn-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "bluecolumn-memory": {
      "command": "npx",
      "args": [
        "-y",
        "bluecolumn-mcp"
      ],
      "env": {
        "BLUECOLUMN_API_KEY": "your-value",
        "BLUECOLUMN_API_URL": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "bluecolumn-memory": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "bluecolumn-mcp"
      ],
      "env": {
        "BLUECOLUMN_API_KEY": "your-value",
        "BLUECOLUMN_API_URL": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • BLUECOLUMN_API_KEY secret required env
    Your BlueColumn API key. Get a free key at https://bluecolumn.ai
  • BLUECOLUMN_API_URL env
    BlueColumn API base URL for the audio-intelligence layer (/v1/audio/*, /v1/calls/*, /v1/sound/*, /v1/music/*). Defaults to http://localhost:8000 (local FastAPI backend).

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Bluecolumn Memory safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: BLUECOLUMN_API_KEY

Does it run on my computer or in the cloud?

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).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.4.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

🧠 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
ToolDescription
rememberIngest text, audio, or documents into persistent memory
recallQuery memory with natural language, get AI-synthesized answer + sources
noteStore lightweight agent observations as searchable vectors
namespaceShow the configured namespace
Music Memory (new)
ToolDescription
music_rememberStore 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_recallSearch 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
ToolDescription
audio_ingestIngest calls, voice notes, podcasts, meetings, or music and extract semantic memory
audio_recallSearch audio memories and get audio-backed citations
call_prepareGet memory context before a voice call starts
call_completeStore what changed after a call ends
sound_analyzeDetect and index non-speech audio events
music_analyzeExtract tempo, structure, instrumentation, mood from music
Streaming audio memory
ToolDescription
streaming_audio_ingestIngest edge-device audio chunks (car, doorbell, wearable) into per-device streaming memory
streaming_audio_recallRecall 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

FeatureBlueColumn MCPOther 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.
