Pulled straight from the server with tools/list on 2026-10-17.
optionality_check_balanceread-only

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

optionality_purchase_credits

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.

optionality_check_payment

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.

optionality_restore_credits

Credit a patron's ledger from a BTCPay-settled invoice. **RESTRICTED to the operator** — the operator owns the books and is the only party who can issue a manual credit grant. Patrons who believe they paid but never got credits must escalate to the operator's support, who then invokes this tool on their behalf. Use cases: cold-start vault races during check_payment, ncred delivery hiccups, pat

optionality_account_statementread-only

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.

optionality_account_statement_infographicread-only

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.

optionality_report_issue

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)

optionality_service_statusread-only

Check the health and configuration of this service. Free.

optionality_request_echoread-only

Echo what the client sent with this request. Free. Reports the URL path and query, the headers, the cookies and the MCP request ``_meta``. Values are SHA-256 fingerprints, so nothing a client sends is repeated back; equal fingerprints mean equal values. Call it from two conversations and compare: a value that stays the same within one and changes between them identifies the conversation.

optionality_get_operator_onboarding_statusread-only

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.

optionality_get_patron_onboarding_statusread-only

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.

optionality_session_statusread-only

Check operator readiness. Returns the operator lifecycle state and clear guidance on what to do next. Free. Lifecycle states: - ready: Vault AND pricing model verified on this call. Proceed with tool calls — this is the answer the moment the vault is up. - warming_up: Persistence could not be reached on this call (a transient failure, seen, not assumed). Retry; the next call completes the

optionality_request_credential_channel

Open a Secure Courier channel for credential delivery. This is the CREDENTIAL-DELIVERY flow — use it to hand over a service secret (API keys, tokens). To merely prove you control an npub (the usual answer to a ``proof_required`` error), use ``request_npub_proof`` instead. Note: dynamic/OAuth2 services (e.g. Schwab) need NO couriered secret — check ``service_status`` first. Sends a welcome DM

optionality_receive_credentialscan modify

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 poppe

optionality_forget_credentialscan modify

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.

optionality_update_patron_credential

Add or update a single patron credential field. Merges into existing stored credentials without affecting other fields. Useful for setting an account identifier after OAuth, changing a default brain, etc. Free. Proof of npub ownership is required — this is a write to the patron's sensitive credential vault.

optionality_update_operator_credential

Add or update a single operator secret field. Merges into the operator's stored credentials without touching the others — the field-level counterpart to re-delivering the whole bundle over Secure Courier. Use it to rotate one secret (a reissued ``btcpay_api_key``, say) without restating the six you did not change, where any field omitted from a courier reply is destroyed. The value is never ec

optionality_delete_patron_credentialcan modify

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.

optionality_delete_operator_credentialcan modify

Remove a single operator secret field. Deletes one key from the operator's encrypted credential blob without touching the others — the field-level counterpart to ``forget_credentials``, which wipes the whole row. Use it to retire a leftover after an SDK cutover (a Prefect key after Modal, or a stored but untemplated orphan like ``anthropic_api_key``) without taking the operator down for a full

optionality_get_patron_credential_fieldsread-only

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 fi

optionality_request_npub_proof

Request npub ownership proof from a patron via Nostr DM. This is the npub-OWNERSHIP-PROOF flow — use it when a call returns ``proof_required``. It proves the caller controls an npub; it does NOT deliver any service secret. To hand an operator its API keys or OAuth secrets, use ``request_credential_channel`` instead. Sends a challenge DM that the patron must sign and reply to using their Nostr

optionality_receive_npub_proofcan modify

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

optionality_check_proof_statusread-only

Check whether a proof grant 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. Expiry is read from the grant itself; the only store consulted is the patron's revocation watermark. Free, no side effects — touches no relay.

optionality_oracle_how_to_joinread-only

Get DPYC onboarding instructions from the Oracle. Free.

optionality_oracle_get_tax_rateread-only

Get the current DPYC certification tax rate. Free.

optionality_oracle_lookup_memberread-only

Look up a DPYC community member by npub. Free.

optionality_oracle_aboutread-only

Describe the DPYC ecosystem via the Oracle. Free.

optionality_oracle_network_advisoryread-only

Get active network advisories from the Oracle. Free.

optionality_check_authority_balanceread-only

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.

optionality_get_pricing_modelread-only

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.

optionality_set_pricing_modelcan modify

Set the active pricing model. RESTRICTED to operator. Requires a valid proof (Schnorr-signed kind-27235 event) proving the caller holds the operator's nsec.

optionality_reset_pricing_modelcan modify

Erase all pricing models and restore a viable default. Deletes every stored model, then self-initializes a fresh one from the tool registry — all tools at 0 sats with proper UUIDs. Returns the new model. RESTRICTED to operator — requires proof (nsec-signed).

optionality_request_adoption

Ask a chosen Authority to adopt this operator (deferred courtship). RESTRICTED to the operator — requires proof the caller controls this operator's npub. Resolves the Authority's MCP endpoint from the community registry, mints an inline ownership proof with this operator's nsec, and delivers the request MCP-to-MCP. The Authority records it as pending; its owner approves on their own time. Poll

optionality_adoption_statusread-only

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).

optionality_restore_neon_schema

Prepare this operator's database schema again, ignoring the breadcrumb. Diagnostic / recovery tool for when Neon keeps answering 4xx and the operator suspects a table or grant is missing. Every statement is idempotent, so a clean re-run is harmless; the breadcrumb is rewritten at the end. Returns one step per concern, with Neon's own error text inline for any that failed. RESTRICTED to operator

optionality_list_canonical_identitiesread-only

Return canonical (tool_id, mcp_name, …) for every tool the wheel exposes. 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. Includes both ToolIdentity-seeded tools and any UUID recorded by ``@paid_tool`` that i

optionality_get_nostr_profileread-only

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.

optionality_publish_nostr_profilecan modify

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.

optionality_check_priceread-only

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.

optionality_list_constraint_typesread-only

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.

optionality_mint_coupon

Create a new operator-owned discount coupon. The coupon owns its binding: ``tool_ids`` names the tools it discounts, and re-pricing a tool never touches it. A coupon bound to no tool discounts nothing, however many patrons redeem it.

optionality_list_couponsread-only

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.

optionality_update_coupon

Patch a coupon's editable fields. Pass only the fields you want to change. To set a cap to unlimited (NULL in the schema), pass ``clear_uses_per_patron=true`` or ``clear_total_uses=true``. Renaming the code is allowed — existing patron redemption rows survive (they key on coupon id). ``tool_ids`` replaces the coupon's binding — tool ids or MCP tool names, ``["*"]`` for every paid tool, ``[]

optionality_delete_couponcan modify

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.

optionality_redeem_coupon

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 ex

optionality_list_my_couponsread-only

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``.

optionality_forget_couponcan modify

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``.

optionality_notarize_ledger

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.

optionality_get_notarization_proofread-only

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

optionality_list_notarizationsread-only

List recent Bitcoin notarization records.

optionality_deal_scenario

Generate a fresh options trading scenario and open a journal entry.

optionality_fetch_scenario

Redeem a deal_scenario claim check. Free. While ``status`` is ``running``, wait ``poll_after_seconds`` and call again. When ``done``, ``result`` holds the deal_scenario response (``entry_id`` + ``scenario``). ``expired`` means the claim is unknown or its result aged out — start a new deal_scenario request.

optionality_ask_tip

Get a non-spoiler Socratic hint for an open journal entry.

optionality_fetch_tip

Redeem an ask_tip claim check. Free. While ``status`` is ``running``, wait ``poll_after_seconds`` and call again. When ``done``, ``result`` holds the ask_tip response (``tip``). ``expired`` means the claim is unknown or its result aged out — ask again.

optionality_judge_tradecan modify

Evaluate the trainee's trade. Persists evaluation, parses legs, recomputes leaderboard.

optionality_fetch_judgement

Redeem a judge_trade claim check. Free. While ``status`` is ``running``, wait ``poll_after_seconds`` and call again. When ``done``, ``result`` holds the judge_trade response (``entry_id`` + ``evaluation``). ``expired`` means the claim is unknown or its result aged out — submit the trade again.

optionality_save_draftcan modify

Persist a draft trade proposal without running the judge.

optionality_list_journalread-only

Server-side sorted, grouped, paginated list of the caller's journal. Sorting and grouping are done in SQL, so each page is a slice of the fully-ordered dataset. Returns ``{total, page, page_size, groups, entries}``; ``groups`` carries per-group counts over the whole set.

optionality_get_journalread-only

Return the full journal entry including scenario + evaluation.

optionality_delete_journalcan modify

Hard-delete a journal entry and recompute the leaderboard cache.

optionality_share_entry

Toggle a journal entry's share flag. Shared, evaluated entries appear under the patron's row on the public Leaderboard for peer learning. Priced at 0 sats — the social value of sharing is the point, not the revenue.

optionality_get_shared_entriesread-only

List a target patron's shared evaluated entries — newest first. Public, free read: anyone (including guests) can browse the trades a leaderboard peer has chosen to share. Eager-loads the evaluation and trade proposal so the FE can render the full assessment with no follow-up call. No npub/proof envelope — this is a bootstrap-style tool the FE invokes without identity injection.

optionality_get_leaderboardread-only

Global leaderboard ordered by ``sort_by``.

optionality_get_my_rankread-only

The caller's leaderboard row plus their ordinal rank under ``sort_by``.

optionality_set_display_namecan modify

Set the caller's display name on the leaderboard.

optionality_get_patron_profileread-only

Return the caller's profile — display_name, avatar, bio, relays.

optionality_set_profilecan modify

Update any subset of the caller's profile fields.

optionality_escrow_nsec

Deposit a freshly-generated nsec for operator-managed Nostr signing. Trade-off: sovereignty for UX. Optionality holds the nsec encrypted in Neon (AES-256-GCM, key derived from operator nsec). Until you withdraw it, the operator can sign Nostr DMs on your behalf. Use this only for fresh game-persona keypairs — never for an existing Nostr identity that lives elsewhere. The nsec MUST derive to th

optionality_withdraw_nseccan modify

Return the plaintext nsec once and remove it from operator storage. Required acknowledgment string (exact match): "I understand I am now solely responsible for this nsec." After this call you regain full self-custody; the operator forgets the key. You're now responsible for stashing it in a Nostr client (0xchat, Damus, Amber) and signing DMs locally via NIP-07.

optionality_send_patron_dm

Sign and publish a Nostr DM as the patron, using the escrowed nsec. The patron's escrowed nsec is loaded, decrypted in-process, used to sign a kind-4 NIP-04 DM + a kind-1059 NIP-17 gift wrap, broadcast via the operator's relay pool, then the plaintext drops out of scope. The DM's `pubkey` is the patron's own — recipients see it as authored by the patron, not relayed. Returns {"success": True,

optionality_get_escrow_statusread-only

Return ``{"escrowed": bool}`` — whether Optionality holds the patron's nsec. Free; the FE polls this to render Withdraw vs Deposit affordances on the Profile page.

optionality_get_api_usage_statsread-only

Aggregated LLM usage and cost for this patron's calls. Returns ``{"models": [{"model", "runs", "total_calls", "total_input_tokens", "total_output_tokens", "total_cost_usd", "priced_runs"}, ...], "totals": {...}}``. One row per distinct model the patron's tool calls have invoked. ``total_cost_usd`` is what the PROVIDER reported for those calls, not a figure reconstructed from a price table — to
