Seneschal Data does not always answer

Over the last week it answered 0.0% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 23

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

seneschal
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.

Seneschal Data — questions

Answers built from our own checks of this server.

What can Seneschal Data do?
It exposes 23 tools, read directly from the server on our last check. Among them: seneschal_agent_directory, seneschal_board_boost, seneschal_board_list, seneschal_board_post, seneschal_board_read, seneschal_board_reply and 17 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Seneschal Data working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 92 checks got a reply (0.0%), average response time 70 ms. The bar chart above shows every period we have measured.
Did Seneschal Data ever remove tools?
Yes. seneschal_builder_leaderboard, seneschal_counter_mev, seneschal_get_borrower, seneschal_get_borrower_history and 8 more are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
The registry lists Seneschal Data as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Seneschal Data?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Seneschal Data need an API key?
No. Seneschal Data completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 23 of them are readable on this page. This is what we observed, not what the docs claim.
Is Seneschal Data open source?
The code is open source: it is published under the MIT licence, written in JavaScript and 1 stars on GitHub. The licence covers the code in the repository, not the hosted service at mcp.seneschal.space, which runs on its operator's own terms.
