What this server does
In its own words. Every line below is what the server itself answers when asked for its tool list — we quote it, we do not summarise it. The wording is the operator's, not ours.
| Tool | What the server says it does |
|---|---|
weather_account_statementneeds: dpop_token, npub | 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 â not the operator's Authority tax balance. Free â no credits consumed. Proof of npub ownership is required to prevent statement-scraping of arbitrary patrons. |
weather_account_statement_infographicneeds: dpop_token, npub | 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. |
weather_adoption_statusneeds: authority_npub | 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). |
weather_check_authority_balanceno arguments | 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 â not a patron balance. Free. |
weather_check_balanceneeds: dpop_token, npub | Check a patron's credit balance at this operator. This is the patron's spending balance â 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 â no credits required. Proof of npub ownership is required to prevent anyone-with-the-registry from enumerating |
weather_check_paymentneeds: dpop_token, invoice_id, npub | Check the payment status of a Lightning invoice. Call after paying the invoice from purchase_credits. Free â no credits required. Proof of npub ownership is required to prevent credit-grant front-running by an observer of the invoice ID. |
weather_check_priceneeds: tool_id | Preview the effective cost of a tool call. Shows the base cost and any constraint effects (discounts, free trials, surge pricing). Free â no credits required. |
weather_check_proof_statusno arguments | 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 â touches no relay. |
weather_currentneeds: latitude, longitude | Get current weather conditions for a location. Returns temperature, wind speed, and weather code from Open-Meteo. |
weather_delete_couponneeds: coupon_id | 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) â the Studio surfaces orphan references as warnings. RESTRICTED to operator â requires proof. |
weather_delete_operator_credentialneeds: dpop_token, field | Remove a single operator secret field. Deletes one key from the operator's encrypted credential blob without touching the others â 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 |
weather_delete_patron_credentialneeds: dpop_token, field, npub | Remove a single patron credential field. Deletes one field from stored credentials without affecting other fields. Free. Proof of npub ownership is required â this is a write to the patron's sensitive credential vault. |
weather_forecastneeds: latitude, longitude | Get a multi-day weather forecast for a location. Returns daily high/low temperatures and precipitation for 1-16 days. |
weather_forget_couponneeds: coupon_id, npub | Remove a coupon from this patron's redemption list. Cosmetic only â the coupon itself still exists at the operator, and the patron can re-redeem the same code later while the window allows. Free â requires proof of ``npub``. |
weather_forget_credentialsneeds: dpop_token, npub, service | 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 â a deletion is as destructive as a write. |
weather_get_nostr_profileno arguments | Read an npub's public Nostr profile (NIP-01 kind-0 metadata). Free, no proof â 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. |
weather_get_notarization_proofneeds: notarization_id, npub | Generate a Merkle inclusion proof that a patron's balance was included in a Bitcoin-notarized snapshot. |
weather_get_operator_onboarding_statusno arguments | 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. |
weather_get_patron_credential_fieldsneeds: dpop_token, npub | 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 â 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 |
weather_get_patron_onboarding_statusneeds: dpop_token, patron_npub | 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. |
weather_get_pricing_modelno arguments | 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. |
weather_historicalneeds: end_date, latitude, longitude, start_date | Get historical weather data for a location and date range. Returns daily temperature and precipitation from Open-Meteo's archived model runs, at roughly 2 km and covering 2018 onward. |
weather_list_canonical_identitiesno arguments | Return canonical (tool_id, mcp_name, â¦) 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 â no name-based UUID derivation, no guessing. Includes both ToolIdentity-seeded tools and any UUID recorded by ``@paid_tool`` that i |
weather_list_constraint_typesno arguments | 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 â no credits required. |
weather_list_couponsno arguments | List every coupon this operator has minted (newest first). Each row carries the current ``times_redeemed`` counter â the Studio renders a progress bar from this against ``total_uses``. RESTRICTED to operator â requires proof. |
weather_list_my_couponsneeds: npub | 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 â requires proof of ``npub``. |
weather_list_notarizationsno arguments | List recent Bitcoin notarization records. |
weather_mint_couponneeds: discount_percent, name, valid_from, valid_until | 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. |
weather_notarize_ledgerno arguments | 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 â no credits required. |
weather_oracle_aboutno arguments | Describe the DPYC ecosystem via the Oracle. Free. |
weather_oracle_get_tax_rateno arguments | Get the current DPYC certification tax rate. Free. |
weather_oracle_how_to_joinno arguments | Get DPYC onboarding instructions from the Oracle. Free. |
weather_oracle_lookup_memberneeds: npub | Look up a DPYC community member by npub. Free. |
weather_oracle_network_advisoryno arguments | Get active network advisories from the Oracle. Free. |
weather_publish_nostr_profileno arguments | 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 â no proof token, no key custody. Free. |
weather_purchase_creditsneeds: dpop_token, npub | 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 â no credits required to call. |
weather_receive_credentialsno arguments | 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 |
weather_receive_npub_proofno arguments | 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)`` â the ``dpop_token`` being the value returned by ``request_npub_proof``. The tool drains |
weather_redeem_couponneeds: code, npub | 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 â no credits required. Requires proof of ``npub``. Idempotent: redeeming the same code twice returns the ex |
weather_report_issueneeds: body, dpop_token, npub, title | 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** â no npub / no proof, no issue â 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) |
