What the publisher says
From the Xahau MCP repository's README, as published. We do not edit it. Read it on GitHub
xahau-mcp
A Model Context Protocol server for the Xahau network with two firsts: it runs a Hook's real WebAssembly bytecode in a local VM (no xahaud node required), and it runs a Hooks-specific static-analysis / security rule engine over it — both fully offline. Around that core it adds read-only ledger access, a Xahau-aware binary codec, an instruction-count fee estimate, network-reward math, governance helpers, and unsigned-transaction builders.
Xahau is the XRPL fork whose flagship feature is Hooks — small on-ledger WebAssembly smart contracts. There was no MCP for Xahau and no static analyzer for Hooks; this is both.
The trifecta — safe Hooks, end to end
Three open-source tools, one workflow: write → simulate one tx → prove all inputs. xahau-mcp is the simulate stage.
Why it's useful
Point any MCP-capable agent (Claude, etc.) at this server and it can:
- See the future before signing — simulatetransaction is a pre-sign flight simulator: every hook an unsigned transaction would trigger runs as real bytecode against live ledger state, with per-hook accept/rollback, decoded emitted transactions, simulated state writes and labeled static engine preflights. Its sibling whatif is a time machine: replay any real historical transaction — with your modifications — at its original ledger. Verified to reproduce a real claim's emitted GenesisMint payout to the drop (72,251,963 drops), test-locked.
Shortened. The full README is on GitHub.
Nothing above is checked by us. What we check is on the safety report.
