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.
