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

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" } } } }

Restart Claude Desktop. Your agent now has persistent memory.

Usage

Once configured, your agent can:

Remember this: our API uses Voyage AI embeddings at 512 dimensions → Uses the `remember` tool automatically What embedding model does our API use? → Uses the `recall` tool to query memory Note: user prefers bullet points over paragraphs → Uses the `note` tool for quick observations
