Generate a patron's account statement at this operator. Returns the patron's purchase history, active credit tranches, per-tool usage breakdown, and recent daily usage logs. This is the patron's spending account — not the operator's Authority tax balance. Free — no credits consumed. Proof of npub ownership is required to prevent statement-scraping of arbitrary patrons.

Generate a visual SVG infographic of your account statement. Returns the same data as account_statement, rendered as a dark-themed SVG graphic with balance hero, metrics cards, health gauge, tranche table, and tool usage breakdown. Costs 1 api_sat per call. Proof is verified by ``debit_or_deny`` before any cost is incurred.

Check this operator's adoption-request status at a chosen Authority. Free. Polls the Authority MCP-to-MCP for the status of this operator's request (pending / approved / rejected / provisioned).

Start the OAuth2 authorization flow. Returns an authorization URL. Open it in a browser to log in and authorize. Then call ``check_oauth_status`` with the same npub to complete. Free. Proof of npub ownership is required so an observer cannot DOS your account by initiating OAuth flows in your name. Do NOT call this pre-emptively. If a session may still be valid, attempt the live tool call first and only begin OAuth when it fails with ``upstream_auth_refresh_needed``. A 'pending' ``check_oauth_status`` is not evidence that an existing session has lapsed.

Check this operator's tax balance at the Authority. Returns the sats available for certifying patron credit purchases. When this balance reaches zero, patron top-ups cannot be certified and the operator must call purchase_credits on the Authority. This is the operator's own funding — not a patron balance. Free.

Check a patron's credit balance at this operator. This is the patron's spending balance — credits purchased via Lightning for tool calls at this operator. For the operator's own balance at the Authority (needed to certify patron purchases), use authority_check_balance instead. Free — no credits required. Proof of npub ownership is required to prevent anyone-with-the-registry from enumerating balances.

Check whether the OAuth2 authorization flow has completed. Call after opening the authorization URL from ``begin_oauth`` and completing the login in your browser. Free. Proof of npub ownership is required: OAuth status exposes which upstream services a patron has connected. A 'pending' result here does NOT prove an existing session has lapsed — it only reports this authorization attempt. To find out whether a session still works, attempt the live call; fall back to ``begin_oauth`` only on an explicit ``upstream_auth_refresh_needed`` error.

Check the payment status of a Lightning invoice. Call after paying the invoice from purchase_credits. Free — no credits required. Proof of npub ownership is required to prevent credit-grant front-running by an observer of the invoice ID.

Preview the effective cost of a tool call. Shows the base cost and any constraint effects (discounts, free trials, surge pricing). Free — no credits required.

Check whether a previously-cached dpop_token is still valid. Mirrors ``check_oauth_status`` for the npub-proof flow: a calling agent can ask "will my next paid call accept this dpop_token?" before burning credits on a guaranteed failure. Free, no side effects — does not evict the cache or touch relays.

Delete a coupon. Cascades to all patron redemptions. Any chain step referencing the deleted coupon_id becomes a no-op (the constraint returns neutral on unknown ids) — the Studio surfaces orphan references as warnings. RESTRICTED to operator — requires proof.

Remove a single patron credential field. Deletes one field from stored credentials without affecting other fields. Free. Proof of npub ownership is required — this is a write to the patron's sensitive credential vault.

Remove a coupon from this patron's redemption list. Cosmetic only — the coupon itself still exists at the operator, and the patron can re-redeem the same code later while the window allows. Free — requires proof of ``npub``.

Delete vaulted credentials for a specific service and npub. For operator credentials, pass the operator's own npub. For patron credentials, pass the patron's npub. Always requires proof of npub ownership — a deletion is as destructive as a write.

List Schwab account numbers and their hash identifiers. Call after completing OAuth. Returns accounts with hash values needed for brokerage data tools. Then call ``update_patron_credential(field="account_hash", value=<hash>)`` to set your preferred account. Free (no api_sats deducted) but **proof-gated**: the caller must prove Schnorr-control of ``npub`` via ``request_npub_proof`` + ``receive_npub_proof`` first, then pass the resulting token here. Without the proof check, an attacker who knew a patron's public npub could fetch that patron's Schwab account hashes (IDOR).

Get the active Schwab account's current balance summary. Pulls Schwab's account endpoint and returns four bold lines: **Cash Balance:** currentBalances.cashBalance **Buying Power:** currentBalances.buyingPower **Net Liquidation:** currentBalances.liquidationValue **Day P&L:** currentBalances.liquidationValue − initialBalances.liquidationValue Day P&L is the session change in mark-to-market equity (the canonical measure of "how much did I make/lose today"). Schwab's account response does not expose a single "dayProfitLoss" field — the convention is to compute the delta against the start-of-day snapshot. Two fallback guards apply to Day P&L: 1. Missing snapshot — if either initialBalances or currentBalances is absent or has a zero liquidationValue, Day P&L reports 0.0 rather than treating zero as the baseline (which would print today's full equity as P&L). 2. Suspect snapshot — if the computed Day P&L is larger in absolute value than half of current liquidation value (e.g. $17,442 P&L on an $8,847 account), the initialBalances snapshot is treated as stale or partial and Day P&L reports 0.0. A legitimate 50%+ session change is implausible for any normal account; the tool underreports in the rare real-50% case rather than emitting nonsense in the more common stale-snapshot case. When Day P&L reads $0.00 on a session where you expect a real number, one of those two guards fired. Cross-check against position-level P&L via get_brokerage_positions.

Get full details for a single order by Schwab order ID. Returns the same one-line markdown format as get_brokerage_orders, with the average fill price computed across all executionLegs: - **<orderId>** [<status>] <orderType> | <legs> | Price: $X @ $avg_fill | Filled: <qty> | <enteredTime> Use this when you already have an orderId (e.g., from get_brokerage_orders or from a fill notification) and want a single crisp row rather than the full history list.

Get order history for the active Schwab account. Returns one markdown row per order: - **<orderId>** [<status>] <orderType> | <leg1> / <leg2> / ... | Price: $X @ $avg_fill | Filled: <qty> | <enteredTime> Each leg formats as "<instruction> <quantity>x <symbol>" (e.g. "BUY 1x AAPL", "SELL_TO_OPEN 5x AAPL 240315C00185000"). The avg_fill suffix is the average across all executionLegs.price values for the order; omitted if the order has no fills yet. Date-window default — when from_date and to_date are both blank, the tool defaults to the last 30 days (in UTC). Pass either parameter to override; if you pass one, pass both. Schwab's order status enum (values you can pass to status_filter): AWAITING_PARENT_ORDER, AWAITING_CONDITION, AWAITING_STOP_CONDITION, AWAITING_MANUAL_REVIEW, ACCEPTED, AWAITING_UR_OUT, PENDING_ACTIVATION, QUEUED, WORKING, REJECTED, PENDING_CANCEL, CANCELED, PENDING_REPLACE, REPLACED, FILLED, EXPIRED, NEW.

Get current positions in the active Schwab account, with automatic vertical-spread detection. Pulls Schwab's account endpoint with fields="positions" and emits up to three markdown sections, omitting any that are empty: ## Spreads — vertical spreads detected from paired option legs: - <underlying> <spread_type> (<short_strike>/<long_strike> P|C exp <date>, DTE <n>) | Credit: $X | Max Loss: $Y | Current: $Z | P&L: $W ## Options (unmatched) — single legs not paired into a spread: - <underlying> <strike> P|C exp <date> (DTE <n>) | Qty: ±N | Avg: $X | MktVal: $Y | P&L: $Z ## Equities — long/short share positions: - <symbol> | Qty: ±N | Avg: $X | Price: $Y | P&L: $Z Quantities are computed as (longQuantity − shortQuantity) — short positions show as negative numbers in Qty. Spread detection is heuristic: legs of the same underlying with matching expiration and put/call type, opposite long/short direction, and adjacent strikes get paired. Anything that doesn't fit cleanly drops into Options (unmatched). The tool does not currently detect iron condors, butterflies, or calendars — those will appear as multiple Options (unmatched) rows.

Get full details for a single transaction by Schwab transaction ID. Returns the same one-line markdown format as get_brokerage_transactions: - **<activityId>** [<type>] <tradeDate> | <symbols/qtys> | Net: $<amount> Use this when you have a specific transactionId (from get_brokerage_transactions, a journal entry, or a confirmation) and want the canonical row rather than scanning a history window.

Get transaction history for the active Schwab account. Returns one markdown row per transaction: - **<activityId>** [<type>] <tradeDate> | <qty>x <symbol> | <qty>x <symbol> ... | Net: $<amount> Symbols come from the transaction's transferItems collection (one item per leg, e.g. equity bought + cash debit), with the per-leg amount as quantity. When no transferItems have symbols, the row falls back to the transaction's description text in place of the symbol list. Date-window default — when from_date and to_date are both blank, the tool defaults to the last 30 days (in UTC). Pass both or neither. Schwab's transaction type enum (values you can pass to transaction_types): TRADE, RECEIVE_AND_DELIVER, DIVIDEND_OR_INTEREST, ACH_RECEIPT, ACH_DISBURSEMENT, CASH_RECEIPT, CASH_DISBURSEMENT, ELECTRONIC_FUND, WIRE_OUT, WIRE_IN, JOURNAL, MEMORANDUM, MARGIN_CALL, MONEY_MARKET, SMA_ADJUSTMENT. Empty string = all types.

Get trading hours for one or more market types. Returns nested markdown — one block per market product Schwab knows about within the requested categories: **<Product Name>** — OPEN | CLOSED Pre Market: YYYY-MM-DDTHH:MM — YYYY-MM-DDTHH:MM Regular Market: YYYY-MM-DDTHH:MM — YYYY-MM-DDTHH:MM Post Market: YYYY-MM-DDTHH:MM — YYYY-MM-DDTHH:MM Sessions are emitted only when Schwab reports hours for them — a closed market on a weekend or holiday will have no session lines under it.

Get top movers for a market index — Schwab's curated mover screener. Returns up to 20 rows (capped server-side here, not by Schwab) in a markdown table.

Read an npub's public Nostr profile (NIP-01 kind-0 metadata). Free, no proof — the data is already public on relays. Returns the latest metadata fields (name, display_name, about, picture, banner, nip05, website, lud16) or an empty profile if none is published.

Generate a Merkle inclusion proof that a patron's balance was included in a Bitcoin-notarized snapshot.

Report this operator's configuration readiness. Shows which operator settings are configured, which are missing, and how to deliver each missing value. For patron-level credential status, use get_patron_onboarding_status instead. Free.

Get a filtered option chain suitable for spread evaluation. Returns a markdown table of surviving contracts with one row per leg. Header line carries the underlying price and the active filter constants.

List stored patron credential field names (not values). Returns the names of fields stored for a patron, plus each field's ``delivered_at`` ISO-8601 timestamp when known (null for secrets vaulted before timestamps were recorded). Values are never exposed — use this to verify which fields are configured and how old each one is. Free. Proof of npub ownership is required: the list of configured fields is itself sensitive (reveals which integrations a patron has set up).

Report a patron's credential readiness for this operator. For set-once services (eXcalibur, TheBrain), shows which patron secrets are configured and which are missing. For dynamic/OAuth2 services (Schwab), reports that no patron credentials are needed. Free. Proof of npub ownership is required because credential presence is sensitive information about the patron's setup.

Get historical OHLCV candle data for a symbol. Returns a markdown table of the most recent candles within the requested period, capped at the last 30 rows for readability. A footnote line is added when truncation occurs so the agent knows more data was available.

Get the active pricing model for this operator. Free. If no model exists, self-initializes a scaffold with all registered tools at 0 sats. No economic data from code.

Get real-time quotes for one or more symbols.

Return canonical (tool_id, mcp_name, …) for every registered tool. The authoritative source for any client (Studio, agents, FE) that needs to know how this MCP identifies its tools. Reconcile uses this output to UUID-join against the stored pricing model — no name-based UUID derivation, no guessing. If the operator renames a function or rebrands a slug, the mcp_name in this output changes but tool_id stays. That's the whole point of the canonical-UUID design. Free, no side effects.

List all available constraint types and their parameter schemas. Returns the type, category, description, and parameter specs for every constraint that can be used in a pricing pipeline. Free — no credits required.

List every coupon this operator has minted (newest first). Each row carries the current ``times_redeemed`` counter — the Studio renders a progress bar from this against ``total_uses``. RESTRICTED to operator — requires proof.

List the coupons this patron has redeemed on this operator. Returns both active and exhausted redemptions with a per-row ``status`` (``active`` / ``window_closed`` / ``patron_limit`` / ``total_limit``). Free — requires proof of ``npub``.

List recent Bitcoin notarization records.

Create a new operator-owned discount coupon.

Build a Merkle tree of all patron balances and submit the root to Bitcoin via OpenTimestamps. Operator-only background task. Bitcoin confirmation takes 1-6 hours. Free — no credits required.

Describe the DPYC ecosystem via the Oracle. Free.

Get the current DPYC certification tax rate. Free.

Get DPYC onboarding instructions from the Oracle. Free.

Look up a DPYC community member by npub. Free.

Get active network advisories from the Oracle. Free.

Publish a CLIENT-SIGNED kind-0 profile to relays for an npub. The wheel never holds a patron nsec. The frontend signs the kind-0 metadata event with the patron's session key or a NIP-07 extension and passes the signed event (JSON) here; the wheel verifies the signature matches the npub, then relays it to public relays. The signature is the authorization — no proof token, no key custody. Free.

Buy credits via Bitcoin Lightning. Creates a Lightning invoice. Pay it with any Lightning wallet, then call check_payment to confirm. Proof of npub ownership is required so credits land in the correct ledger. Free — no credits required to call.

Pick up credentials from the Secure Courier. Completes the CREDENTIAL-DELIVERY flow (the ownership-proof counterpart is ``receive_npub_proof``). **Call this only after the user confirms they have replied.** Deterministic, one-shot retrieval: name the response you want with ``(sender_npub, service, dpop_token)`` and the tool drains ONLY the rendezvous relay that channel was pinned to. Every popped DM with the wrong session phrase is deleted and its sender is NACK'd; the first DM with the matching phrase is accepted (ACK'd) and the scan stops. If none match, the queue is drained and a ``courier_not_found`` result is returned. Do NOT poll, loop, or retry. If a credential_card (ncred1...) is provided, it is redeemed directly without any relay access (dpop_token not required for that path). On success, the payment processor client is reinitialized from the new credentials — no server restart needed.

Receive npub ownership confirmation from a patron. Completes the npub-OWNERSHIP-PROOF flow (the credential-delivery counterpart is ``receive_credentials``). **Call this only after the user confirms they have replied.** Deterministic, one-shot retrieval: name the response with ``(patron_npub, dpop_token)`` — the ``dpop_token`` being the value returned by ``request_npub_proof``. The tool drains ONLY the pinned rendezvous relay that challenge was published on, stopping at the DM whose phrase matches. Mismatched DMs are deleted and NACK'd (without revealing the expected phrase). If called before the user replies, their message will never be found. Do NOT poll, loop, or retry. The signed DM itself proves npub ownership (the patron's nsec signed it). On success, returns the ``dpop_token`` — the same token. The calling application MUST remember it and pass it as the ``dpop_token`` parameter on every subsequent paid tool call. The proof (a hash of the token) is stored in the vault keyed by that hash — the MCP never stores the raw token itself. Free.

Claim a coupon by its name (the code the operator shared). Looks up the operator's coupon by ``code``, validates the window and total cap, and records a per-patron redemption row. Subsequent paid tool calls on this MCP auto-apply the discount until ``uses_per_patron`` is exhausted. Free — no credits required. Requires proof of ``npub``. Idempotent: redeeming the same code twice returns the existing redemption.

File a field report about this service as a GitHub issue on the operator's repo. Found a tool's metadata or response wrong or confusing? Report it where the tool lives. The **author of record is your npub** — no npub / no proof, no issue — and it is stamped into the issue so the report is attributed to you, not the operator. Costs a small fee (a free write to an issue tracker would be abused). The report is PUBLIC and goes to the maintainers' normal triage; nothing is verified here. Returns the filed issue's repo, number, and url. If this operator has not enabled field reports, returns an "issue reporting not configured" situation and you are not charged.
