MCP server for the XRPL-Utilities portfolio. 11 tools across four services: • XR-Sentinel — classify any XRPL wallet by its on-chain activity pattern. Returns a 0–100 activity_score, a Low/Medium/High/Dormant level, behavioral signals from a 22-entry catalog, top counterparties with XRPScan labels, and an AI-generated reasoning narrative. • XR-Pulse — normalized signal feed mixing public-source news (regulatory press + central banks + crypto media filtered for XRP/RLUSD/XRPL), on-chain whale activity, and XLS-70/80/81 permissioned-domain lifecycle events. Each row carries 4-hour XRPL price correlation, institutional watchlist labels, and Sentinel cross-references. • XR-Telemetry — XRPL macro snapshot. Total/circulating/escrowed/dormant supply, AMM-locked, exchange omnibus, DEX orderbook depth, and a derived Active Float model with the full additive mathematical bridge. Two payment flows: inline x402 OR async invoice (deeplink + QR). • XR-Trust — directory + drill-down for the XRPL permissioned-asset stack. PermissionedDomain (XLS-80) enumeration, credential issuer aggregation, XLS-81 permissioned-DEX trade economics, and XLS-40 DID identity bridge with .well-known/xrp-ledger.toml resolution. Stateless passthrough proxy — every paid call uses the caller's own x402 v2 payment header (XRP or RLUSD), settled on XRPL mainnet via the t54 facilitator. $0.10 USD per query. The MCP server holds no wallets and takes no cut.

AnchorRegistry is the open provenance layer for the agentic economy. Every digital artifact — code, research, data, models, media, agents, transactions — can be anchored to Base L2 with a permanent, machine-resolvable identifier (an AR-ID). When an AI assistant encounters an SPDX-Anchor or DAPX-Anchor tag in a README, paper, model card, or website, this MCP server lets it resolve the artifact's full provenance record in one call: who anchored it, when, what type it is, manifest hash, and whether the tree has been sealed, retracted, voided, or affirmed. This is the verify-only edition (v0.1). Three read-only, authless tools wrap the public AnchorRegistry verify endpoints. Free, no API key, no account, no rate limit beyond defaults. Future versions will add registration, balance, and seal tools once the MCP credential pattern stabilizes.
