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.

Connect

The hosted server lives at https://api.firestarter.network/mcp (streamable HTTP; WebSocket on the same path). Pick your client:

Claude.ai (web, desktop app, mobile). Settings → Connectors → Add custom connector → paste the server URL. Claude discovers the OAuth endpoints automatically and walks you through signing in with your Firestarter account — no API key needed.

Claude Code.

claude mcp add --transport http firestarter https://api.firestarter.network/mcp

Authenticate via the OAuth prompt, or set a Bearer API key header if you prefer a key.

Claude Desktop (offline-friendly extension). Download the packaged extension from https://api.firestarter.network/mcp/download (or grab firestarter.mcpb from the latest GitHub release), open it with Claude Desktop, and paste your API key when prompted — it is stored in your OS keychain.

Any other MCP client. Remote: point it at the server URL with Authorization: Bearer fs_live_… (or fs_test_… for sandbox). Local stdio:

FIRESTARTER_API_KEY=fs_test_... npx -y @analog-labs/firestarter-mcp

Get an API key at firestarter.network/dashboard; full setup docs at firestarter.network/mcp.

Authentication

Two supported schemes:

• OAuth 2.0 — the server publishes RFC 9728 / RFC 8414 discovery metadata and answers unauthenticated requests with a WWW-Authenticate challenge. Dynamic client registration (RFC 7591) and PKCE S256 are supported, so OAuth-capable hosts (claude.ai, ChatGPT, Claude Code) connect with no pre-shared secret.
• API keys — fs_live_… / fs_test_… Bearer tokens from the dashboard, for clients and scripts that prefer a static credential.

What's inside

86 tools, 7 resources, and 10 prompts covering the full commerce lifecycle:

• Buying — search and price real products, approve-gated checkout, receipts, delivery tracking, returns, disputes, and an inline shopping grid (MCP Apps) for browsing results.
• Buyer safety — saved addresses, payment methods, spend caps, and auto-approve limits.
• Price monitoring — watches with scheduled checks and notifications.
• Selling — listings, repricing, imports, Shopify/TikTok/store connectors, order fulfillment, analytics, and payouts.
• Community markets & drops — curated storefronts with revenue sharing.

Every tool declares readOnlyHint / destructiveHint / openWorldHint annotations, enforced by tests, so MCP hosts can apply the right confirmation policy per call.

Developing

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; FIRESTARTER_API_URL overrides the API base for sandbox use.

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.

Privacy Policy

This section covers the Firestarter Desktop Extension (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.
