Agentcash
Let your agent call x402-protected paid APIs with automatic payment handling instead of wiring micropayment auth by hand.
Overview
Agentcash is a MCP server for the Build phase that calls x402-protected APIs with automatic payment handling for agent workflows.
What is this MCP server?
- npm agentcash MCP server v0.13.4 (stdio)
- Generic client for x402-protected APIs
- Automatic payment handling on eligible requests
- Merit-Systems open-source repo on GitHub
- Version 0.13.4; npm identifier agentcash; stdio transport; described as generic MCP for x402-protected APIs.
What problem does it solve?
Paid APIs behind x402 block your agent until you manually solve payment and retry logic for every integration.
Who is it for?
Builders wiring agents to x402 monetized endpoints who want a reusable MCP payment layer rather than custom scripts.
Skip if: Products that only need free public APIs with no micropayment or 402 gating.
What do I get? / Deliverables
Your MCP client can reach metered APIs with payments handled by Agentcash so integration experiments move faster.
- Agent-callable access to x402-gated APIs with payment handling
- Reusable MCP layer instead of per-API payment scripts
- Faster validation of paid third-party services from the agent

Journey fit
Agentcash is shelved under Build integrations because it connects your coding agent to monetized HTTP APIs during implementation. integrations covers MCP bridges that handle protocol-specific auth and billing for external services your product or agent consumes.
How it compares
x402 payment MCP client, not a Stripe subscription checkout skill for your end users.
Common Questions / FAQ
Who is Agentcash for?
Developers building agent workflows that must call x402-protected, pay-per-use HTTP APIs during integration work.
When should I use Agentcash?
Use it in build when you are connecting Claude Code or another MCP client to APIs that require automatic payment on 402 responses.
How do I add Agentcash to my agent?
Add the stdio npm package agentcash to your MCP configuration and complete wallet or payment setup per Merit-Systems/agentcash documentation.
