# Bullion Tracker MCP (`mowell_labs/bullion-tracker`) Actor SQLite-backed bullion portfolio tracker with live spot price sync. Track gold, silver, platinum, palladium, and copper holdings. Calculates cost basis, unrealized gains, and portfolio performance. - **URL**: https://apify.com/mowell\_labs/bullion-tracker.md - **Developed by:** [Brian Mowell](https://apify.com/mowell_labs) (community) - **Categories:** MCP servers, Agents, Integrations - **Stats:** 1 total users, 0 monthly users, 0.0% runs succeeded, NaN bookmarks - **User rating**: No ratings yet ## Pricing from $5.00 / 1,000 add bullion items This Actor is paid per event and usage. You are charged both the fixed price for specific events and for Apify platform usage.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## Bullion Tracker MCP SQLite-backed bullion portfolio tracker with live spot price sync via yfinance. **Supported metals:** Gold, Silver, Platinum, Palladium, Copper **Known products:** American Eagle, Maple Leaf, Krugerrand, Buffalo, Philharmonic, Britannia, Panda --- ### Tools | Tool | Description | PPE | |------|-------------|-----| | `add_bullion` | Add a holding to the portfolio | $0.005 | | `get_portfolio` | Full item list with live values | $0.005 | | `get_portfolio_summary` | Totals grouped by metal | $0.005 | | `refresh_values` | Sync all values to current spot prices | $0.01 | | `record_sale` | Mark item sold, record realized gain | $0.005 | | `portfolio_performance` | Full P&L: unrealized + realized gains | $0.01 | | `remove_bullion` | Permanently delete an item | $0.005 | --- ### Setup No API keys required. Uses yfinance for spot prices (free). #### Local Development ```bash cd bullion-tracker python3 -m venv venv source venv/bin/activate pip install -r requirements.txt python run_server.py ```` Server starts on `http://localhost:4321/mcp` #### Optional: Custom DB path ```bash export BULLION_DB_PATH="/path/to/bullion.db" python run_server.py ``` *** ### Testing ```python from server import add_bullion, get_portfolio, get_portfolio_summary ## Add a 1 oz gold American Eagle result = add_bullion( user_id="user_123", metal_type="gold", weight_oz="1", bullion_type="coin", product_name="American Eagle", purity=0.9167, purchase_price=2050.00, purchase_date="2024-01-15", purchase_source="APMEX", ) print(result) ## Add 10 oz silver bar result = add_bullion( user_id="user_123", metal_type="silver", weight_oz="10", bullion_type="bar", product_name="Generic Silver Bar", purchase_price=280.00, ) print(result) ## Add fractional gold result = add_bullion( user_id="user_123", metal_type="gold", weight_oz="1/4", bullion_type="coin", product_name="Maple Leaf", purity=0.9999, ) print(result) ## Get portfolio portfolio = get_portfolio(user_id="user_123") print(f"Total value: ${portfolio['total_value_usd']:,.2f}") ## Summary by metal summary = get_portfolio_summary(user_id="user_123") for metal in summary["summary"]: print(f"{metal['metal_type'].title()}: {metal['total_oz']} oz = ${metal['total_value_usd']:,.2f}") ``` *** ### Deploy to Apify ```bash rm -rf venv apify push ``` Re-enable Actor Standby after push. No environment variables required. #### Claude Desktop config ```json { "mcpServers": { "bullion-tracker": { "command": "npx", "args": ["-y", "mcp-remote", "https://YOUR_USERNAME--bullion-tracker.apify.actor/mcp?token=YOUR_APIFY_TOKEN"] } } } ``` *** ### PPE Pricing | Event | Price | |-------|-------| | add-bullion | $0.005 | | portfolio-query | $0.005 | | refresh-values | $0.01 | | record-sale | $0.005 | | portfolio-performance | $0.01 | 80% revenue share on Apify. *** ### Notes - Spot prices cached 1 hour via yfinance futures tickers - Fallback prices used if yfinance unavailable - SQLite stored at `/tmp/bullion_tracker.db` by default (Apify ephemeral storage) - `user_id` isolates portfolios — use a consistent ID per user - `weight_oz` accepts decimals ("0.5") and fractions ("1/4", "1/10") *** ### License MIT — Mowell Labs 2025 ## Actor input object example ```json {} ``` # API You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = {}; // Run the Actor and wait for it to finish const run = await client.actor("mowell_labs/bullion-tracker").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // 📚 Want to learn more 📖?
