Agent Payment MCP
- Abraxas1010/agent-payment-mcp
io.github.Abraxas1010/agent-payment-mcp is a MCP server that enables budget-controlled USDC payments for AI agents on Base.
About
io.github.Abraxas1010/agent-payment-mcp is a Model Context Protocol server that gives developers a controlled way for AI agents to spend real money. Instead of handing an agent an unrestricted wallet, you register API and budget keys so each tool call that triggers a payment respects your ceiling while still settling USDC on Base quickly enough for autonomous workflows like buying credits, data, or third-party API access. Configuration is secret-heavy and intermediate to advanced: you must obtain AgentPMT credentials, pick the correct platform binary, and wire stdio transport in Claude Code or similar hosts. This is an MCP finance integration, not a storefront skill; your agent orchestrates when to pay, and the server enforces provider rules and budgets.
- 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

What it does
Let autonomous agents pay for APIs and services in USDC on Base with budget keys so spending stays capped while workflows run.
Who is it for?
Best when you're 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 you get
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
By the numbers
- USDC on Base blockchain
- Two required secret environment variables: API key and budget key
- Registry version 1.0.1 with platform-specific mcpb binaries

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.
