Agent Payment Mcp
Let autonomous agents pay for APIs and services in USDC on Base with budget keys so spending stays capped while workflows run.
Overview
io.github.Abraxas1010/agent-payment-mcp is a MCP server for the Build phase that enables budget-controlled USDC payments for AI agents on Base.
What is this MCP server?
- USDC settlements on Base blockchain for agent-initiated payments
- Separate AGENT_PAYMENT_API_KEY and AGENT_PAYMENT_BUDGET_KEY for auth plus spend limits
- Instant settlement semantics suited to tool-calling purchase loops
- Shipped as stdio MCP binaries (mcpb) for multiple platforms
- Version 1.0.1 release artifacts on GitHub with pinned file SHA256
- USDC on Base blockchain
- Two required secret environment variables: API key and budget key
- Registry version 1.0.1 with platform-specific mcpb binaries
What problem does it solve?
Agents that need to buy external services create a trust problem: unrestricted wallets let one bad tool loop drain funds before you notice.
Who is it for?
Solo builders shipping agent products that must autonomously pay metered APIs or on-chain services with explicit spend caps.
Skip if: Human checkout flows, traditional card billing dashboards, or teams that forbid agents from moving funds on any chain.
What do I get? / Deliverables
After install, your agent can trigger USDC payments through MCP with API authentication and budget keys so spending stays bounded and settles on Base.
- Agent-callable payment tools with USDC settlement on Base
- Budget-enforced spend path separate from API authentication
- Production-oriented MCP binary integration for agent workflows
Recommended MCP Servers
Journey fit
Payment rails are wired during Build when you connect agent tooling to real money movement, not during early idea research. Integrations is the canonical shelf because this MCP server is an external payment API bridge with secrets and runtime binaries, not a standalone product UI.
How it compares
On-chain agent payment MCP with budget keys, not a Stripe Checkout skill or a manual invoicing integration.
Common Questions / FAQ
Who is io.github.Abraxas1010/agent-payment-mcp for?
Developers building autonomous agents who need USDC payments on Base with provider-side budget controls instead of open-ended wallet access.
When should I use io.github.Abraxas1010/agent-payment-mcp?
Use it during Build integrations when your agent must pay for third-party resources programmatically and you already have AgentPMT API and budget keys.
How do I add io.github.Abraxas1010/agent-payment-mcp to my agent?
Download the matching mcpb binary release, set AGENT_PAYMENT_API_KEY and AGENT_PAYMENT_BUDGET_KEY in your MCP server environment, and register the stdio server in Claude Code or your MCP host.
