Firestarter MCP Server

The Model Context Protocol server for Firestarter — AI-native commerce execution. Lets an AI assistant search real products, buy them with your approval, track deliveries, and run a seller business end to end.

Distributed two ways:

Surface	How
Claude Desktop	Install the .mcpb desktop extension (npm run build:mcpb)
Any MCP client	Point it at https://api.firestarter.network/mcp with a Bearer API key

Quick start

npm ci
npm run build        # builds the inline shopping UI, then compiles
npm test
npm run build:mcpb   # produces mcpb/dist/firestarter.mcpb

Set FIRESTARTER_API_KEY (fs_live_... for live orders, fs_test_... for sandbox) to run the stdio server. Get a key at firestarter.network/dashboard.

Safety model

Purchases never complete without an explicit approval step: firestarter_execute finds and prices options, and only firestarter_approve charges. Tools that move money or delete records are annotated destructiveHint: true so MCP hosts prompt before running them; read-only tools are annotated so they don't.

This section covers the Firestarter Desktop Extension (apps/api/mcpb), which runs the Firestarter MCP server locally and calls the Firestarter API on your behalf.

What is collected. The extension holds one credential you supply at install time: your Firestarter API key. Claude Desktop stores it in your operating system's keychain, not in plaintext config. Beyond that, the extension sends only what a request needs — the product search or listing you ask about, and, when you approve a purchase, the order and delivery address tied to it. It reads no files and collects no telemetry of its own.

How it is used and stored. Requests go over TLS to https://api.firestarter.network (overridable via the api_url config for sandbox use) and are handled under the policy linked above. Order, listing, and account records are stored server-side to run the service. Payment card numbers are never stored by Firestarter; card details are handled by the payment processor, and stored secrets are kept as cryptographic hashes.

Third-party sharing. Data is shared only where completing the transaction requires it — principally the merchant fulfilling your order, plus payment and shipping providers. It is not sold, and there is no third-party advertising or tracking.

Retention. Data is retained while your account is active; execution logs are retained for 90 days. You may export your data or request deletion of your account from the dashboard, or by writing to the address above.

Your control. Uninstalling the extension removes the stored API key from your keychain and ends its access. Revoking the key in the Firestarter dashboard has the same effect immediately, from any device.
