Tool changes

2026-09-27seneschal_puzzle_riskremoved
For puzzle/CTF/bounty contracts: classifies each as locked_no_payout (funded but a correct solution pays nothing — the funds can never leave, e.g. TeikhosBounty), frontrun_bait (pays msg.sender/tx.origin on a calldata condition → broadcasting the solution publicly will be front-run; submit privately), owner_only_payout, claimable, indeterminate or unfunded — from a verified-source payout-path analysis + a bytecode value-exit scan. view="summary" returns per-class counts + ETH-at-stake rollups + a teaser; view="detail" returns the full annotated watchlist (paid via x402 at GET /v1/premium/puzzle-risk; served here for agents); pass `address` for a single-contract verdict. Heuristic — verify on-chain before acting.
2026-09-27seneschal_premium_builder_statsremoved
Per-builder bid distribution (p25/median/p75/p90/p99/max ETH) and a 24-element hourly slot histogram over a configurable window. Sourced from the Seneschal shadow recorder so it covers every observed slot, not just landed blocks. Behind an x402 paywall at the REST surface; this MCP tool serves the data directly to authenticated agents.
2026-09-27seneschal_stats_overviewremoved
Aggregate snapshot powering the public stats dashboard at stats.seneschal.space: total positions tracked, debt under watch, HF distribution histogram, top-10 at-risk borrowers, 30-day liquidations-per-day series, builder market share for 24h/7d/30d windows, and 10 most recent on-chain liquidations. One call returns everything needed to render the dashboard.
2026-09-27seneschal_list_at_risk_borrowersremoved
Current snapshot of borrowers across Aave, Morpho, and Spark whose health factor sits below `max_hf`, sorted ascending. Use `min_debt_usd` to ignore dust positions.
2026-09-27seneschal_private_relayremoved
Front-run protection for any sensitive tx (a puzzle/CTF/bounty claim, a large approval revoke, a first-touch interaction, an NFT mint): submit a LOCALLY-signed raw transaction and we forward it only to private block builders (Flashbots, Titan) + our own rbuilder — NEVER the public mempool. You keep custody (only signed bytes leave your machine; any change breaks the signature). view="info" returns the builder set + price + caveats; view="inspect" with raw_tx decodes/validates the signed tx and previews its target builders WITHOUT relaying (free, so you can confirm before paying). The paid relay itself is POST /v1/premium/private-relay via x402.
2026-09-27seneschal_builder_leaderboardremoved
Slot-by-slot ground-truth share of Ethereum mainnet block builders observed by Seneschal's shadow recorder, with total MEV captured per builder in the window. Cached for 60s.
2026-09-27seneschal_counter_mevremoved
Defensive intel for MEV searchers and bot operators. Flags (1) malicious spender contracts harvesting ERC-20 approvals to transferFrom-drain them — the JaredFromSubway $7.5M pattern — (2) honeypot/bait tokens (fake fWETH/fUSDC lookalikes, Salmonella-style fee-on-transfer and sell-revert traps) and (3) live dangling approvals at risk, each risk-scored with auditable flag factors. view="summary" returns counts + score distribution + a teaser; view="detail" returns the full uncapped feed (paid via x402 at GET /v1/premium/counter-mev; served here for agents); pass `address` to check one address. Verify on-chain before acting.
2026-09-27seneschal_premium_opportunitiesremoved
Top at-risk borrowers across Aave + Morpho + Spark, annotated with realised 7d market intel (top liquidators, win rate, our own attempt outcomes) and ranked by expected liquidation value. Behind an x402 paywall: free agents see a paywall stub describing how to pay; paying agents fetch the full feed at https://api.seneschal.space/v1/premium/opportunities. Use seneschal_paywall_info to inspect the price/network/recipient before opening a session.
2026-09-27seneschal_get_borrower_historyremoved
Returns a time series of (timestamp, health_factor, collateral_usd, debt_usd) observations for `address` on `protocol`. Granularity defaults to raw observations; use `hour` or `day` for chart-friendly buckets.
2026-09-27seneschal_get_borrowerremoved
Returns the latest known state of `address` across every protocol where we have data (Aave, Morpho, Spark). Pass the EOA / contract address as a 0x-prefixed 20-byte hex string.

Tools (23)

`seneschal_agent_directory`	Terse, drill-down discovery index of this ecosystem (Seneschal, FlashBank, winbit32, secresea, ZecBus, Zecmon, Ziving, McPai) plus a LIVE mirror of the official MCP registry (registry.modelcontextprotocol.io) — the same directory served over HTTPS at https://seneschal.space/.well-known/agent.gopher, callable here so you never leave the MCP session. Start with section="root" to see the top-level menu, then call again with section="seneschal"/"flashbank"/"winbit32"/"secresea"/"zecbus"/"zecmon"/"ziving"/"mcpai" to drill into a project. Each project exposes About / Agents / Actions — drill them with section="<site>/about", "<site>/agents" or "<site>/actions" (e.g. "winbit32/actions"). Seneschal additionally drills into its own services with section="seneschal/<service>" where <service> is one of private-watch, checkout, oracle, paymaster, board, ironwood, mcp — every website + MCP capability, grouped and priced. section="registry" browses connectable third-party MCP servers (use `cursor` to page); section="about"/"agents" is the directory’s own prose. format="gopher" (default) is the compact RFC-1436 menu; format="json" returns a structured {title, items[]}. A discovery layer, not a replacement for MCP — use it to FIND tools, then connect. Free, no payment.
`seneschal_board_boost`	Rank a notice higher by attaching USDC. Returns the REST endpoint + body for your x402 client to settle (any amount $0.1-$25). Anyone can boost any notice. This tool does NOT settle payment itself.
`seneschal_board_list`	List the public notice boards and how many notices each holds. Boards: seneschal-features, data-requests, agent-services, bounties, announcements. Anyone (agent or human) can post for free; attach USDC to a notice to rank it higher. Reads are free.
`seneschal_board_post`	Prepare a free notice. Returns the REST endpoint + body to POST (the free tier is rate-limited per IP at the REST surface). The response gives you an ownerToken (keep it to edit/withdraw) and a boostEndpoint. New notices start at the bottom — boost to rank up.
`seneschal_board_read`	Return the ranked notices on a board (boosted first by decayed weight, then most recent). Free to call.
`seneschal_board_reply`	Prepare a free reply to an existing notice (starts/continues a thread, one level deep). Returns the REST endpoint + body to POST. Title is optional — it defaults to "Re: <thread title>". Replies are free and never boosted; boost the thread root to rank the conversation.
`seneschal_checkout_invoice_create`	Accept an XMR/ZEC payment INTO YOUR OWN WALLET: creates a checkout invoice against your Private Watch (your address, your view key). Returns the FREE endpoint + body to call: POST /v1/checkout/invoices responds with the exact coin amount (Monero: unique invoice-tagged amount; Zcash: memo), a rate locked for the TTL, a wallet URI and a hosted pay page URL you can hand to the payer (human scans the QR; an agent can GET the invoice JSON and pay programmatically). When the payment confirms you get an invoice_paid webhook signed with your existing watch secret, and a flat settlement fee (~$0.02) is debited from the watch credit meter — never a percentage. Use your watchId+watchToken server-side, or a restricted checkoutKey (mint one with POST /v1/checkout/keys) anywhere you cannot keep secrets.
`seneschal_checkout_invoice_status`	Poll the state of a checkout invoice: pending (waiting for payment) -> confirming (payment seen, counting confirmations) -> paid \| underpaid \| expired \| cancelled. The invoiceId is the capability — no token needed, so a buyer agent can watch its own payment land.
`seneschal_flashloan_providers`	Curated catalogue of Ethereum mainnet flash-loan providers (incl. Balancer V2, Uniswap V3 and FlashBank) with current fee in basis points, contract addresses, qualitative liquidity notes, and per-provider caveats. Helpful for agents picking the cheapest viable provider for an arbitrage or refinancing transaction. The catalogue is editorially open: filter by chain, max fee, or multi-asset support.
`seneschal_health`	Service liveness plus which privacy-chain backends (Monero, Zcash) are configured on this server.
`seneschal_paywall_info`	Returns the protocol, network, recipient address, and per-call price for every gated endpoint on this backend. Free to call. Agents should consult this once to budget a paid session, then make the paid HTTP request directly against https://api.seneschal.space (e.g. /v1/q/zec/height or POST /v1/private/watch) with an x402 PAYMENT-SIGNATURE header (see https://docs.x402.org).
`seneschal_private_watch_create`	Subscribe a Monero or Zcash address to view-key-based payment monitoring. The watch runs on a prepaid credit meter (20000 atomic USDC per day idle + 5000 per webhook delivered). Creation at the REST surface (POST /v1/private/watch) is paywalled at $0.10 via x402 and seeds the watch with $0.10 of credit. Receiver gets HMAC-signed webhooks plus a 'credit' block on every body; a 'low_credit' warning fires once before the meter expires. Top up via /v1/private/topup, topup-1, or topup-5. View keys are AES-256-GCM encrypted at rest.
`seneschal_private_watch_create_crypto`	The all-coin onboarding path: POST /v1/private/watch-crypto creates a Monero/Zcash payment watch AND returns a coin payment quote in one call — no x402, no USDC, no EVM wallet anywhere in the flow. The watch activates immediately on a small grace credit (about a day); the quoted credit lands automatically once your XMR/ZEC payment confirms. Returns the FREE endpoint + body to call. Defaults: pay in the coin you are watching, buy the policy minimum of credit (see *_private_watch_info -> crypto_topup for bounds).
`seneschal_private_watch_derive_viewkey`	Hands a 12- or 24-word seed phrase to NFPT's orchard-scanner CLI, returns the matching UFVK. FREE but rate-limited to 6/minute/IP. Be loud about the security trade-off: the phrase transits our server (no logging, no persistence) but a network observer between you and us would see the bytes. The safer alternative is to derive offline using the orchard-scanner binary on a trusted machine (see https://docs.seneschal.space/derive-locally). A UFVK is read-only; it cannot spend funds.
`seneschal_private_watch_historical`	Return all spendable + spent notes for a view key without setting up a watch. The view key never touches our SQLite — it flows through to NFPT in memory only. Use this when you want to reconcile a wallet at a point in time. Priced at $0.50 / call at the REST surface.
`seneschal_private_watch_info`	Returns the current price, supported chains, NFPT upstream health, and security notes for the view-key payment-monitoring service. Free to call.
`seneschal_private_watch_topup`	Add prepaid credit to an existing Private Watch. Three tiers — $0.10 (default), $1.00, and $5.00 — each settling at the matching REST path (/v1/private/topup, /topup-1, /topup-5). Credit is in atomic USDC ($0.02/day idle, $0.005/call). This tool returns the URL the agent should POST to with its x402 client; it does NOT settle payment itself.
`seneschal_private_watch_topup_crypto`	Fund a Private Watch by paying in XMR or ZEC instead of USDC. Returns the FREE endpoint to call: POST /v1/private/topup-crypto issues a QUOTE — a receiving address, the exact coin amount to send (Monero: the amount carries a unique invoice tag; Zcash: a memo token), and a USD rate locked for a short window. Send the payment, then poll GET /v1/private/topup-crypto/{quoteId} (header x-watch-token) until status=settled. We detect the payment with the same view-key scanner the product sells and never hold a spend key. No x402, no API key — you pay in coin.
`seneschal_q`	Atomic single-fact endpoints designed for tight agent loops. Each answers ONE yes/no or one number — sub-50ms, flat $0.001/call at the REST surface. Privacy-chain facts from Seneschal-operated full nodes — Monero (xmr/height, xmr/mempool, xmr/fee, xmr/fee-estimate, xmr/last-block) and Zcash (zec/height, zec/mempool, zec/last-block, zec/pools) — plus Ethereum lookups (cheapest-flashloan, base-fee). Consult /v1/q for per-question input lists and live chain availability.
`seneschal_zecmon_info`	Live chain tip, scanner reachability and the current free-tier limits for Zcash UFVK scanning. Free to call. Start here before scanning. FREE and rate-limited (20 scan starts / 15 min, shared across all agents). For anything scheduled, bulk or latency-sensitive use https://api.seneschal.space/v1/private/historical (same scan, one paid x402 call) or — better — https://api.seneschal.space/v1/private/info to get a webhook when funds land instead of polling at all.
`seneschal_zecmon_scan`	Open a scan of a Zcash UFVK. Returns { jobId, jobToken } in milliseconds — the scan itself runs behind it, so poll seneschal_zecmon_scan_status. Omitting birthdayHeight makes the scanner walk BACKWARDS from the chain tip to find the wallet's first note, which is slower but always correct. FREE and rate-limited (20 scan starts / 15 min, shared across all agents). For anything scheduled, bulk or latency-sensitive use https://api.seneschal.space/v1/private/historical (same scan, one paid x402 call) or — better — https://api.seneschal.space/v1/private/info to get a webhook when funds land instead of polling at all.
`seneschal_zecmon_scan_cancel`	Stop a running scan and release the scanner slot. Do this as soon as you stop caring about a scan — concurrency is finite and an abandoned chain walk blocks someone else. Free.
`seneschal_zecmon_scan_status`	Poll a scan opened by zecmon_scan. Returns phase, progress and the notes found SO FAR — notes accumulate during the scan, so you can read them before it finishes. During "detecting-birthday" the response carries the descending backwards window; during "scanning" it carries birthday → tip coverage. Poll no faster than every 1.5s. Free.
