Stats Compass

Quick Start

pip install stats-compass-mcp

Claude Desktop

stats-compass-mcp install --client claude

VS Code (GitHub Copilot)

stats-compass-mcp install --client vscode

Claude Code (CLI)

claude mcp add stats-compass -- uvx stats-compass-mcp run

Note: The first connection may fail while uvx downloads the package. If this happens, disable and re-enable Stats Compass in your MCP settings — subsequent connections will be instant.

Restart your client and start asking questions about your data.

What Can It Do?

Run stats-compass-mcp list-tools to see all available tools.

How to Prompt

Start your message with "Use stats compass to..." — this tells the AI to use the Stats Compass tools instead of trying to write code or use other methods.

Use stats compass to load ~/Downloads/sales.csv and run EDA on itUse stats compass to find my CSV files in DownloadsUse stats compass to clean the dataset and handle missing valuesUse stats compass to create a histogram of the price columnUse stats compass to test if there's a significant difference in scores between group A and BUse stats compass to train a classification model to predict churnUse stats compass to load sell_out.xlsx and tell me if last week's sales at each retailer were unusual, leaving out the promotions in promo_calendar.csvUse stats compass to measure what the June promotion added at Tesco, using promo_calendar.csv

Tip: Without this prefix, some AI clients may try to write Python code or use shell commands instead of the Stats Compass tools — especially for tasks like finding files on your machine.

Loading Files

Local mode: Start with "Use stats compass to load..." and provide the file path or folder.

Use stats compass to load the CSV at ~/Downloads/sales.csvUse stats compass to find my data files in ~/Documents

Remote/HTTP mode: Use the upload feature (see below).

Remote Server Mode

For Docker deployments or multi-client setups:

stats-compass-mcp serve --port 8000

serve binds 127.0.0.1 by default. To accept connections from other machines, set a bearer token of at least 16 characters and bind a public address:

export STATS_COMPASS_AUTH_TOKEN="$(openssl rand -hex 24)"export STATS_COMPASS_SECRET_KEY="$(openssl rand -hex 32)"   # encrypts upload/download linksstats-compass-mcp serve --host 0.0.0.0 --port 8000

Clients send Authorization: Bearer <token>. Without a token the server refuses a public address; --no-auth overrides that, with a warning, for a network you trust. Each session reads only its own uploads and writes only its own exports. Upload and download links carry an encrypted token that expires (downloads after 24 hours, STATS_COMPASS_DOWNLOAD_TTL_SECONDS), never the session id.

A session idle for 24 hours is removed, with its data, models and exported files (STATS_COMPASS_SESSION_IDLE_HOURS; 0 turns it off). A session in the middle of a tool call is never removed. A server that embeds the tools runs its own sweep with SessionManager.evict_idle(max_idle).

File Uploads

When running remotely, users can upload files via browser:

You: I want to upload a fileAI: Open this link to upload: http://localhost:8000/upload?session_id=abc123
[Upload in browser]
You: I uploaded sales.csvAI: ✅ Loaded sales.csv (1,000 rows × 8 columns)

Downloading Results

Export DataFrames, plots, and trained models:

You: Save the cleaned data as a CSVAI: ✅ Saved. Download: http://localhost:8000/exports/.../cleaned_data.csv

Connect Clients to Remote Server

VS Code (native HTTP support):

{  "servers": {    "stats-compass": { "url": "http://localhost:8000/mcp" }  }}

Claude Desktop (via mcp-proxy):

{  "mcpServers": {    "stats-compass": {      "command": "uvx",      "args": ["mcp-proxy", "--transport", "streamablehttp", "http://localhost:8000/mcp"]    }  }}

Docker

docker run -p 8000:8000 -e STATS_COMPASS_SERVER_URL=https://your-domain.com stats-compass-mcp
