OpenClaw MPP plugin

Official MPP plugin for OpenClaw.

This package is published as a beta while the integration is being developed and tested.

v0 goal

Make finite OpenClaw HTTP responses payment-aware without changing OpenClaw core.

The first version should:

• load on gateway startup
• install mppx payment-aware fetch for finite gateway HTTP responses
• expose an explicit mpp_fetch tool for requests that should use the payment-aware fetch directly
• support free requests, Tempo charge, and non-streaming Tempo session challenges
• allow any origin by default, with optional origin restrictions
• support a gateway TEMPO_PRIVATE_KEY while wallet setup is being designed

Paid session streams are out of scope for v0.

Local development

pnpm install
pnpm build
pnpm check
openclaw plugins install --link .
openclaw plugins enable mpp
TEMPO_PRIVATE_KEY=0x... openclaw gateway run

Use MPP_ALLOWED_ORIGINS or plugins.entries.mpp.config.allowedOrigins to restrict which origins the plugin may pay.

Implementation plan

1. Validate the package shape with OpenClaw locally.
2. Confirm startup Mppx.create(...) covers fetch calls made by OpenClaw/plugin code after the plugin loads.
3. Add wallet.tempo.xyz setup for Tempo access keys.
4. Add optional EVM/x402 support with evm.charge.
5. Publish behind ClawHub review only after the local UX works end to end.
