xrpl-mpp-mcp
Framework-neutral implementation of the native MPP JSON-RPC/MCP payment transport.
pip install xrpl-mpp-mcp
The package provides capability advertisement; root and MCP-nested _meta
handling; operation-bound challenges and request hashes; replay-safe callback
processing; successful receipt metadata; and the exact payment error mapping:
-32042payment required-32043verification failed-32602malformed credential-32603processor failure
Paid operations are tools/call, resources/read, and prompts/get.
Credentials use org.paymentauth/credential; receipts use
org.paymentauth/receipt. Conflicting metadata placement is rejected and paid
notifications that cannot receive a response are dropped.
This package is not an MCP server framework and does not settle XRPL payments by itself. Inject application verification and settlement callbacks.
