ASG Card
Let a coding agent issue and manage virtual spend cards settled in Stellar USDC through x402 without you hand-authorizing every purchase.
Overview
ASG Card MCP is a Build-phase MCP server that gives AI agents tool-based virtual card management via x402 and Stellar USDC.
What is this MCP server?
- Exposes ASG Card virtual card lifecycle to MCP clients over stdio via @asgcard/mcp-server
- Settlement path uses Stellar USDC with x402-style autonomous agent payments
- Targets builders shipping agent products that must pay vendors or APIs programmatically
- npm package 0.5.0 with server schema version 0.5.13
- MCP integration layer—not a one-off Claude skill for card UI
- npm package @asgcard/mcp-server at 0.5.0 with stdio transport
- Registry id io.github.ASGCompute/asgcard-mcp-server
What problem does it solve?
Agents that need to pay for services still depend on you to paste cards or approve charges manually.
Who is it for?
Indie builders prototyping agent wallets, API budgets, or autonomous procurement on Stellar USDC with MCP-native hosts.
Skip if: Teams that only need a human checkout flow, lack Stellar/x402 setup, or cannot accept agent-controlled spend.
What do I get? / Deliverables
After you register the stdio server, your agent can invoke ASG Card tools for governed virtual spend in USDC instead of one-off human checkout.
- Registered stdio MCP server exposing ASG Card virtual card tools
- Agent-callable payment surface for USDC-settled spend workflows
- Documented integration point for autonomous procurement experiments

Journey fit
Payment rails are wired during product build when agents need real-world spend APIs, not at launch or grow analytics. Virtual card and x402 hooks are third-party integrations that extend what your agent can call at runtime.
How it compares
Payments MCP integration for agent spend, not a generic code-review or SEO skill.
Common Questions / FAQ
Who is ASG Card MCP for?
Solo and indie developers shipping AI agents that must hold and spend USDC on virtual cards without constant manual approval.
When should I use ASG Card MCP?
Use it during Build when you integrate payment rails so your agent can call card tools over MCP before you ship autonomous purchase flows.
How do I add ASG Card MCP to my agent?
Install @asgcard/mcp-server from npm, configure ASG Card and x402/Stellar credentials per ASGCompute docs, and add the stdio server entry to your MCP client config.
