  • screener_put_call_ratio, screener_linkedin, screener_app_ratings, screener_reddit_mentions, screener_government_contracts, screener_patent_filings

• 🧹 Consistent, model-friendly shapes (we normalize raw API responses)

• 📱 app_ratings_by_ticker returns a blended series — one row per date, carrying the company's biggest app on each store — plus apps, a summary of every app it publishes (platform, app_id, app_name, observation_count, latest_score, latest_ratings_count) and app_count. A company can publish many apps (Apple has 140 on iOS), so answering a per-app question from series would describe one app as though it covered the whole company: read apps to see what exists, then pass app_id to get that app's own observations. The summary carries no observations by design — 140 apps' history would flood the context. app_id is null on rows predating per-app keying (the platform is known, the app is not), and an unknown app_id returns available_app_ids rather than an empty series

• 🏛️ insider_transactions_by_ticker, government_contracts_by_ticker, corporate_lobbying_by_ticker, and patent_filings_by_ticker rows carry cik — the company's SEC Central Index Key as of the record, a 10-digit zero-padded string ("0000320193"; keep it text, the leading zeros are part of the identifier), null when the record has no entity resolution. Use it to join rows to SEC-keyed datasets (EDGAR filings, 13F holdings) or a security master

• 🔑 Provide your API key via the FINBRAIN_API_KEY environment variable (a shell env var or your MCP client's env block)

Install

Option A — Standard install (pip)

# macOS / Linux / Windows
pip install --upgrade finbrain-mcp

Option B — Dev install (editable)

# from repo root
python -m venv .venv
source .venv/bin/activate # Windows: .\.venv\Scripts\activate
pip install -e ".[dev]"

Keep pip (prod) and your venv (dev) separate to avoid path mix-ups.

Option C — Docker

# Build the image
docker build -t finbrain-mcp:latest .

# Run with your API key
docker run --rm -e FINBRAIN_API_KEY="YOUR_KEY" finbrain-mcp:latest

See DOCKER.md for detailed Docker usage instructions.

---

Configure your FinBrain API key

A) In your MCP client config (recommended / most reliable)

Put the key directly in the MCP server entry your client uses (Claude Desktop or a VS Code MCP extension). This guarantees the launched server sees it, even if system env vars aren’t picked up.

Claude Desktop (pip install)

{
  "mcpServers": {
    "finbrain": {
      "command": "finbrain-mcp",
      "env": { "FINBRAIN_API_KEY": "YOUR_KEY" }
    }
  }
}

B) Environment variable

This works too, but note you must restart the client after setting it so the new value is inherited.

# macOS/Linux
export FINBRAIN_API_KEY="YOUR_KEY"

# Windows (PowerShell, current session)
$env:FINBRAIN_API_KEY="YOUR_KEY"

# Windows (persistent for new processes)
setx FINBRAIN_API_KEY "YOUR_KEY"
# then fully quit and reopen your MCP client (e.g., Claude Desktop)

Tip: If the env var route doesn’t seem to work (common on Windows if the client was already running), use the config JSON env method above—it’s more deterministic.

---

Run the server

Note: You typically don’t need to run the server manually—your MCP client (Claude/VS Code) starts it automatically. Use the commands below only for manual checks or debugging.

• If installed (pip):

  finbrain-mcp

• From a dev venv:

  python -m finbrain_mcp.server

Quick health check without an MCP client:

python - <<'PY'
import json
from finbrain_mcp.tools.health import health
print(json.dumps(health(), indent=2))
PY

---

Connect an AI client

No manual start needed: Claude Desktop and VS Code will launch the MCP server for you based on your config. You only need to run finbrain-mcp yourself for quick sanity checks or debugging.

Claude Desktop

Edit your config:

• Windows: %APPDATA%\Claude\claude_desktop_config.json

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

• Linux: ~/.config/Claude/claude_desktop_config.json

Pip install (published package):

{
  "mcpServers": {
    "finbrain": {
      "command": "finbrain-mcp",
      "env": { "FINBRAIN_API_KEY": "YOUR_KEY" }
    }
  }
}

macOS tip (full path):

If "command": "finbrain-mcp" doesn’t work, find the absolute path and use that instead.

which finbrain-mcp    # macOS/Linux
# (Windows: where finbrain-mcp)

Claude config with full path (macOS example):

{
  "mcpServers": {
    "finbrain": {
      "command": "/full/path/to/finbrain-mcp",
      "env": { "FINBRAIN_API_KEY": "YOUR_KEY" }
    }
  }
}

Dev venv (run the module explicitly):

{
  "mcpServers": {
    "finbrain-dev": {
      "command": "C:\\Users\\you\\path\\to\\repo\\.venv\\Scripts\\python.exe",
      "args": ["-m", "finbrain_mcp.server"],
      "env": { "FINBRAIN_API_KEY": "YOUR_KEY" }
    }
  }
}

Docker:

{
  "mcpServers": {
    "finbrain": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "finbrain-mcp:latest"],
      "env": { "FINBRAIN_API_KEY": "YOUR_KEY" }
    }
  }
}

After editing, quit & reopen Claude.

VS Code (MCP)

1. Open the Command Palette → “MCP: Open User Configuration”.
   This opens your mcp.json (user profile).

2. Add the server under the servers key:

   {
     "servers": {
       "finbrain": {
         "command": "finbrain-mcp",
         "env": { "FINBRAIN_API_KEY": "YOUR_KEY" }
       }
     }
   }
   

3. In Copilot Chat, enable Agent Mode to use MCP tools.

What can you ask the agent?

You don’t need to know tool names—just ask in plain English. Examples:

• Predictions

  • “Get FinBrain’s daily predictions for AMZN.”
  • “Show monthly predictions (12-month horizon) for AMZN.”
  • “Get market-wide daily predictions for S&P 500 tickers.”

• News

  • “Get recent news articles for AMZN.”
  • “What’s the news sentiment for AMZN from 2025-01-01 to 2025-03-31 (limit 50)?”
  • “Show me the latest news across all S&P 500 stocks.”

• App ratings

  • “Fetch app store ratings for AMZN between 2025-01-01 and 2025-06-30.”

• Analyst ratings

  • “List analyst ratings for AMZN in Q1 2025.”

  • “Show Reddit mentions for TSLA over the last week.”
  • “Which subreddits are talking about AAPL the most?”

• Government contracts

  • “Show government contracts awarded to LMT in 2025.”
  • “Which companies have the largest government contract awards?”

• Patent filings

  • “Show recent patent filings for AAPL.”

Notes

• Date format: YYYY-MM-DD.
• Time-series endpoints return the most recent N points by default—say “limit 200” to get more.
• Predictions horizon: daily (10-day) or monthly (12-month).
• Say “as CSV” to receive CSV instead of JSON.
• No need to specify a market—just use the ticker symbol directly.

Troubleshooting

• ENOENT (can’t start server)

  • Wrong path in client config. Use the venv’s exact path:

    • …\.venv\Scripts\python.exe + ["-m","finbrain_mcp.server"], or

    • …\.venv\Scripts\finbrain-mcp.exe

• FinBrain API key not configured

  • Put FINBRAIN_API_KEY in the client’s env block or

  • setx FINBRAIN_API_KEY "YOUR_KEY" and fully restart the client.

• Mixing dev & prod installs

  • Keep pip (prod) and venv (dev) separate.

  • In configs, point to one or the other—not both.
