bluecolumn-mcp

MCP server for BlueColumn — persistent semantic memory for AI agents.

Give any MCP-compatible agent (Claude Desktop, LangChain, AutoGen, CrewAI) the ability to remember, recall, and store observations across sessions.

Tools

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

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"
      }
    }
  }
}

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

Example with LangChain

from langchain_mcp import MCPToolkit

toolkit = MCPToolkit(server_name="bluecolumn")
tools = toolkit.get_tools()
# Tools: remember, recall, note — all backed by BlueColumn
