Give Your AI Agents Real Purchasing Power

Stop hardcoding API keys and wrestling with payment flows every time your AI agent needs to buy something. The Fewsats MCP server gives your agents secure, autonomous purchasing capabilities through a clean, developer-friendly interface.

The Commerce Problem Every AI Developer Faces

You're building an AI agent that needs to purchase services—maybe it's buying cloud resources, paying for API calls, or acquiring digital assets. Right now, you're probably juggling multiple payment SDKs, handling sensitive credentials, and building custom payment logic for each service.

That's exactly the kind of repetitive work that should be automated, not rebuilt from scratch every time.

Four Tools That Handle Everything

The Fewsats MCP server provides exactly what you need:

• balance - Check wallet funds before making decisions
• payment_methods - Discover available payment options
• pay_offer - Execute purchases using L402 offers (the emerging standard for AI micropayments)
• payment_info - Track and verify completed transactions

Your agents get purchasing capabilities without you touching payment infrastructure. No more wrestling with Stripe webhooks or building custom billing logic.

Real-World Applications Where This Shines

Autonomous Cloud Scaling: Your monitoring agent detects high load, checks the budget with balance, and automatically spins up additional servers by paying for them through pay_offer.

Dynamic API Usage: Your data processing agent hits rate limits on a free tier, checks available funds, then seamlessly upgrades to a paid plan to continue working.

Content Generation Workflows: Your creative agent needs premium stock photos or AI-generated assets, compares prices across providers, and purchases exactly what it needs without human intervention.

Research and Data Collection: Your analysis agent encounters paywalled research papers or premium datasets, evaluates the cost against the project budget, and makes informed purchasing decisions.

Integration That Actually Works

Getting started takes minutes, not hours:

uvx fewsats-mcp

Add it to your Claude Desktop config:

"mcpServers": {
  "Fewsats Server": {
    "command": "uvx",
    "args": ["fewsats-mcp"],
    "env": {
      "FEWSATS_API_KEY": "YOUR_API_KEY"
    }
  }
}

Your AI agents immediately gain access to secure purchasing without you building payment infrastructure from scratch.

Why This Matters Now

L402 (Lightning HTTP 402) is becoming the standard for AI micropayments—small, programmatic transactions that traditional payment systems handle poorly. This MCP server positions your agents at the forefront of this shift, giving them native purchasing capabilities as the ecosystem develops.

Instead of building payment logic into every agent, you get a standardized interface that works across services. Your development time stays focused on agent intelligence, not payment plumbing.

The future of AI agents isn't just about what they can analyze or generate—it's about what they can autonomously acquire to complete their tasks. This MCP server makes that future available today.
