Which integrations are available for this server?

Allows using MinIO as a storage backend for ArcticDB, enabling structured read/write access to time-series data stored in S3-compatible buckets via the ArcticDB MCP server.

How do I use arcticdb-mcp?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@arcticdb-mcp Show me the last 10 rows of symbol SPX in library market_data" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

arcticdb-mcp An MCP server for structured read/write access to ArcticDB. Overview • Demo • Quick Start • Configuration • Tools • Development

Overview

arcticdb-mcp turns ArcticDB into an AI data copilot. Assistants can automate symbol updates, batch jobs, and time-series queries while built-in versioning protects every change. Go from question to data change in minutes, not scripts, with full traceability. You can also design your own workflows on top of arcticdb-mcp.

Quickstart

Install and run with uvx (recommended):

uvx arcticdb-mcp

Configure your MCP client (Claude Desktop / Cursor / Windsurf / Continue):

{
  "mcpServers": {
    "arcticdb": {
      "command": "uvx",
      "args": ["arcticdb-mcp"],
      "env": {
        "ARCTICDB_URI": "lmdb:///path/to/your/database"
      }
    }
  }
}

Ask your assistant:

"Show me the last 5 rows of AAPL in library finance"
"Create a snapshot of finance before I update symbols"
"List versions for symbol ES_intraday"

Installation

Choose one:

# Recommended
uvx arcticdb-mcp

# Or
pipx install arcticdb-mcp

# Or
pip install arcticdb-mcp

Python requirement: >=3.9

Configuration

Set ARCTICDB_URI in MCP client config or environment.

URI examples

Local LMDB (Linux/macOS): lmdb:///path/to/db
Local LMDB (Windows): lmdb://C:/path/to/db
AWS S3: s3://s3.amazonaws.com:bucket?region=us-east-1&access=KEY&secret=SECRET
Azure Blob: azure://AccountName=X;AccountKey=Y;Container=Z
S3-compatible (MinIO, etc.): s3://your-endpoint:bucket?access=KEY&secret=SECRET

You can also use a .env file:

ARCTICDB_URI=lmdb:///path/to/db

Run Modes

stdio (default)

This is the default mode used by desktop MCP clients.

ARCTICDB_URI=lmdb:///path/to/db python -m arcticdb_mcp

HTTP / SSE

Set ARCTICDB_MCP_PORT to run over HTTP/SSE:

ARCTICDB_URI=lmdb:///path/to/db ARCTICDB_MCP_PORT=8000 python -m arcticdb_mcp

Endpoint:

http://localhost:8000/sse
