Agent X402 Paywall Mcp
Let agents pay for metered API calls via Coinbase x402 (HTTP 402) without setting up a full Stripe merchant flow.
Overview
Agent x402 Paywall MCP is a Build-phase MCP server that integrates Coinbase x402 HTTP 402 pay-per-call payments so agents can access metered APIs without a Stripe merchant setup.

- Designed for agents paying per call without a traditional Stripe account
- stdio MCP via PyPI package agent-x402-paywall-mcp v1.0.2
- Fits API products that expose machine clients instead of only human checkout
- Local MCP process for agent hosts that support stdio servers
- MCP server version 1.0.2
- 1 PyPI package with stdio transport
- Registry identifier: agent-x402-paywall-mcp
What problem does it solve?
Monetizing agent-to-API traffic with human-centric checkout is awkward, and many solo builders lack a simple way to enforce pay-per-call from within the agent loop.
Who is it for?
Builders creating agent-consumable paid APIs or internal tools who want x402-style per-request payment from MCP-enabled coding agents.
Skip if: Products that only need standard Stripe Checkout for human subscribers with no HTTP 402 or agent payment flow.
What do I get? / Deliverables
Your agent can satisfy HTTP 402 payment requirements on gated endpoints through MCP, enabling per-call monetization aligned with x402 rather than full Stripe onboarding.
- MCP-mediated x402 pay-per-call handling for agent API requests
- Integration path that avoids a traditional Stripe merchant account for machine clients
- stdio server agent-x402-paywall-mcp v1.0.2

Journey fit
Pay-per-call wiring belongs while you integrate monetization and external paid services into the product or agent toolchain. Integrations is where HTTP 402 paywall handlers and agent payment flows are connected to your API surface.
How it compares
MCP payment bridge for x402, not a hosted billing dashboard or storefront skill.
