Seneschal Data
Connects Claude to real-time DeFi liquidation data (Aave, Morpho, Spark, Compound) and Ethereum block builder metrics from an operator running their own searcher and builder. Free tier gives you 18 tools to query at-risk positions, recent liquidations, borrower health histories, and builder market share. Paid tiers run on x402 micropayments with no API keys: Premium data delivers EV-ranked liquidation opportunities and per-builder bid distributions, while Private Watch monitors Monero or Zcash wallets via view key and posts webhook events for every inbound payment. The operator exposes their own production surveillance infrastructure as both REST and MCP, so you get slot-by-slot builder telemetry and cross-protocol borrower tracking that nobody else publishes in one place.
