tools
about
Extended narration about DPYC, the Social Contract, and the Oracle.
Fetches README.md and GOVERNANCE.md from the dpyc-community repo and
assembles a comprehensive context answer.
Input schema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
Output schema
{'type': 'object', 'required': ['result'], 'properties': {'result': {'type': 'string'}}, 'x-fastmcp-wrap-result': True}
cast_ban_vote
Cast a Lightning-funded vote in an active ban election.
Not yet implemented â will verify npub membership, validate the
election is active, and record the vote with a Lightning payment proof.
Input schema
{'type': 'object', 'required': ['election_id', 'vote', 'npub'], 'properties': {'npub': {'type': 'string'}, 'vote': {'type': 'string'}, 'election_id': {'type': 'string'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
check_ban_status
Check whether an npub is banned from the DPYC Social Contract.
Looks up the member in the community registry and checks whether
their status is "banned". Unknown npubs are not considered banned
(they simply aren't members).
Free, unauthenticated. Used by operators during the cold path
(credit purchases) to enforce community bans.
Input schema
{'type': 'object', 'required': ['npub'], 'properties': {'npub': {'type': 'string'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
confirm_citizenship
Complete the citizen registration by submitting a signed Nostr event.
This is part of the **citizen** registration flow (Operator-owned).
The Operator calls this on behalf of a patron after the patron has
signed the cryptographic challenge from request_citizenship.
Verifies:
1. The challenge exists and hasn't expired
2. The Schnorr signature is valid
3. The event's pubkey matches the claimed npub
4. The event content contains the issued nonce
5. The npub is not already registered
On success, commits directly to dpyc-community/members/citizens/{npub}.json
to register the new Citizen immediately.
Input schema
{'type': 'object', 'required': ['npub', 'challenge_id', 'signed_event_json'], 'properties': {'npub': {'type': 'string'}, 'challenge_id': {'type': 'string'}, 'signed_event_json': {'type': 'string'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
deregister_operator
Remove an Operator from the DPYC community registry.
Called when an Authority disowns an Operator. An Operator cannot
exist without a sponsoring Authority, so deregistration removes the
member file entirely, returning the Operator to initial state.
Input schema
{'type': 'object', 'required': ['operator_npub', 'authority_npub'], 'properties': {'operator_npub': {'type': 'string', 'description': 'Nostr npub of the Operator to remove.'}, 'authority_npub': {'type': 'string', 'description': 'npub of the Authority requesting deregistration\n(must be a registered authority or prime_authority).'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
economic_model
Explain the DPYC Social Contract economic model â qualitatively.
Describes how value flows through the network: ad valorem
certification fees, the cascade up the Certification Chain to the
First Curator, and where the live numbers actually live. The Oracle
quotes **no** rates, counts, or revenue figures â those belong to the
Authorities' pricing models and the live registry, not to a docent.
Free, unauthenticated.
Input schema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
get_campaign
Retrieve a published pricing campaign.
Input schema
{'type': 'object', 'required': ['author_npub', 'operator_npub', 'slug'], 'properties': {'slug': {'type': 'string', 'description': 'The campaign slug (directory name).'}, 'format': {'type': 'string', 'default': 'json', 'description': '"json" for importable data, "markdown" for readable summary.'}, 'author_npub': {'type': 'string', 'description': "The campaign author's npub."}, 'operator_npub': {'type': 'string', 'description': "The target operator's npub."}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
get_relays
Return the DPYC Nostr relay set, best first.
The single source of truth is ``dpyc-community/relays.json``. An Operator
seeds its relay set from here at cold start (its only fixed dependency is
this Oracle endpoint), then reads its own bootstrap config from Nostr using
just its nsec â no direct GitHub access.
That file is a curated *guess*: it says which relays are worth using, not
which are up this minute. Relays that an operator reported and the Oracle
then proved unreachable are moved to the back of the list; everything else
keeps its declared order, and nothing is ever dropped.
This call never probes anything â it is on every operator's cold-start
path, so it stays a lookup. Ranking improves only when someone hits a dead
relay and says so via ``report_relay_failure``. Report failures only;
successes need no announcement.
Free.
Input schema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
get_rulebook
Fetch the DPYC Social Contract governance document.
Returns the raw markdown of GOVERNANCE.md from the dpyc-community repo.
Input schema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
Output schema
{'type': 'object', 'required': ['result'], 'properties': {'result': {'type': 'string'}}, 'x-fastmcp-wrap-result': True}
get_tax_rate
Explain how Tollbooth certification taxation works.
Taxation is ad valorem and **per-Authority** â there is no single
network-wide number, and the Oracle deliberately quotes none. The
actual fee is the Authority's own accounting, set in its pricing model
and reported at transaction time. This tool is a docent: it explains
the model and points to the live source. For the exact figure, query
the relevant Authority's ``check_price`` for ``certify_credits``.
Input schema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
how_to_add_authority
End-to-end guide for spinning up a new Tollbooth Authority.
Returns the eight-step procedure covering identity, region selection,
GitHub workspace, dpyc-community registry entry, Neon + BTCPay + Horizon
deployment, BTCPay credential delivery via Secure Courier, the
self-registration challenge-response with the parent Authority, and
pre-funding the cert-fee balance. Fetched live from docs/how-to-add-authority.md
in the dpyc-community repo.
Input schema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
Output schema
{'type': 'object', 'required': ['result'], 'properties': {'result': {'type': 'string'}}, 'x-fastmcp-wrap-result': True}
how_to_join
Tier-specific onboarding guide for joining the DPYC Social Contract.
Covers all five tiers: Citizen, Advocate, Operator, Authority, and
First Curator. Includes Nostr keygen instructions and practical next
steps.
Input schema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
Output schema
{'type': 'object', 'required': ['result'], 'properties': {'result': {'type': 'string'}}, 'x-fastmcp-wrap-result': True}
initiate_ban_election
Initiate a community ban election against a member.
Not yet implemented â will create a GitHub Issue with a 72-hour
discussion period and Lightning-funded economic voting.
Input schema
{'type': 'object', 'required': ['target_npub', 'reason'], 'properties': {'reason': {'type': 'string'}, 'target_npub': {'type': 'string'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
list_campaigns
List published pricing campaigns from the DPYC community.
Optionally filter by operator or author npub.
Input schema
{'type': 'object', 'properties': {'author_npub': {'type': 'string', 'default': '', 'description': 'Filter to campaigns by this author (optional).'}, 'operator_npub': {'type': 'string', 'default': '', 'description': 'Filter to campaigns for this operator (optional).'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
list_services
Enumerate the live DPYC service network with self-described summaries.
Reads the member roster from the dpyc-community registry, then (when
``probe=True``) performs a lightweight MCP handshake against each
member's public service endpoint to fetch that service's *own*
self-description and tool inventory. Nothing about the services is
hardcoded here â descriptions are authored by each service, and prices
come from each Operator/Authority pricing model (call the service's
``check_price``).
Resilient by design: per-service timeout, partial results, brief
caching, and a registry-only fallback when an endpoint is asleep or
unreachable. A sleeping service never breaks the listing. Free,
unauthenticated.
Input schema
{'type': 'object', 'properties': {'kind': {'type': 'string', 'default': 'all', 'description': 'Role filter â\x80\x94 "all", "operator", "authority", or "advocate".'}, 'probe': {'type': 'boolean', 'default': True, 'description': 'Handshake each endpoint for a live self-description. Set\nFalse for a fast registry-only listing (no network fan-out).'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
lookup_member
Look up a member by their Nostr npub.
Can look up any role's npub â citizen, operator, or authority.
Returns the full member record if found, or a not-found message.
Input schema
{'type': 'object', 'required': ['npub'], 'properties': {'npub': {'type': 'string'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'required': ['result'], 'properties': {'result': {'anyOf': [{'type': 'object', 'additionalProperties': True}, {'type': 'string'}]}}, 'x-fastmcp-wrap-result': True}
network_advisory
Get current network deployment advisory.
Returns human-readable guidance on what changed recently, urgent
upgrades, and actions operators should take. Fetched live from
ADVISORY.md in the dpyc-community repo.
Input schema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
Output schema
{'type': 'object', 'required': ['result'], 'properties': {'result': {'type': 'string'}}, 'x-fastmcp-wrap-result': True}
network_versions
Get current recommended versions of all Tollbooth components.
Returns component versions, minimum compatibility, active protocols,
and a short advisory summary. Data is fetched live from
network-status.json in the dpyc-community repo.
Input schema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
publish_campaign
Publish a pricing campaign to the DPYC community.
Commits both a machine-importable JSON file and a human-readable
Markdown summary to the dpyc-community campaigns directory.
Input schema
{'type': 'object', 'required': ['author_npub', 'operator_npub', 'campaign_json'], 'properties': {'author_npub': {'type': 'string', 'description': 'The npub of the person who designed the campaign.'}, 'campaign_json': {'type': 'string', 'description': 'The full campaign export as a JSON string.'}, 'campaign_name': {'type': 'string', 'default': '', 'description': 'Optional display name. Derived from JSON if omitted.'}, 'operator_npub': {'type': 'string', 'description': 'The npub of the operator the campaign is for.'}, 'campaign_markdown': {'type': 'string', 'default': '', 'description': 'Optional pre-rendered Markdown. If omitted, the\nOracle generates a basic summary from the JSON.'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
register_advocate
Register a new Advocate in the DPYC community registry.
Advocates are community utility services that provide shared
infrastructure (e.g., OAuth2 callback collectors) but aren't
monetized Operators or certification Authorities.
This is an Oracle-mediated registration â no Nostr DM
challenge-response needed. The Oracle operator (Prime Authority)
trusts the commit via GitHub token.
Input schema
{'type': 'object', 'required': ['npub', 'display_name', 'service_name', 'service_url', 'service_description'], 'properties': {'npub': {'type': 'string', 'description': 'Nostr npub of the Advocate service.'}, 'service_url': {'type': 'string', 'description': 'Public URL of the service.'}, 'display_name': {'type': 'string', 'description': 'Human-readable name for the service.'}, 'service_name': {'type': 'string', 'description': 'Machine-readable service identifier\n(e.g., "tollbooth-oauth2-collector").'}, 'service_description': {'type': 'string', 'description': 'Short description of what the service does.'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
register_authority
Register a new Authority in the DPYC community registry.
Called by an Authority service at the end of the onboarding protocol
(after the candidate proves npub ownership and the Prime Authority
approves). Commits a new ``members/authorities/{npub}.json`` file to
dpyc-community on GitHub.
The full Authority onboarding protocol is a 3-step Nostr DM
challenge-response flow:
1. ``register_authority_npub(npub)`` â Authority sends DM challenge
2. ``confirm_authority_claim(npub)`` â verifies candidate DM, escalates to Prime
3. ``check_authority_approval(npub)`` â Prime approves, this tool is called
Input schema
{'type': 'object', 'required': ['authority_npub', 'display_name', 'service_url', 'upstream_authority_npub'], 'properties': {'service_url': {'type': 'string', 'description': 'Public MCP endpoint URL of the Authority service.'}, 'display_name': {'type': 'string', 'description': 'Human-readable name for the Authority.'}, 'authority_npub': {'type': 'string', 'description': 'Nostr npub of the new Authority curator.'}, 'upstream_authority_npub': {'type': 'string', 'description': 'npub of the sponsoring Authority (must\nalready exist as a prime_authority or authority in the registry).'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
register_operator
Register a new Operator in the DPYC community registry.
Called by an Authority service after the operator requests registration.
The Authority validates the operator's identity and sponsors the
registration by calling this tool via MCP-to-MCP.
Input schema
{'type': 'object', 'required': ['operator_npub', 'display_name', 'service_url', 'authority_npub'], 'properties': {'service_url': {'type': 'string', 'description': 'Public MCP endpoint URL of the Operator service.'}, 'display_name': {'type': 'string', 'description': 'Human-readable name for the Operator service.'}, 'operator_npub': {'type': 'string', 'description': 'Nostr npub of the new Operator.'}, 'authority_npub': {'type': 'string', 'description': 'npub of the sponsoring Authority (must already\nexist as an authority or prime_authority in the registry).'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
renounce_membership
Citizen self-removal from the DPYC Social Contract via automated PR.
Not yet implemented â will create a GitHub PR to remove the member
from the registry.
Input schema
{'type': 'object', 'required': ['npub'], 'properties': {'npub': {'type': 'string'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
report_relay_failure
Report that a relay in the DPYC set was unreachable, and re-rank it.
A report does not set a relay's rank. It asks the Oracle to measure that
relay *now*, and the Oracle's own probe decides. A false or mistaken
report therefore costs one probe and changes nothing â no caller can
demote a healthy relay by asserting that it is down.
Report only failures. Successes are far too frequent to be worth
carrying, and a relay that works needs no announcement.
Input schema
{'type': 'object', 'required': ['relay', 'reporter_npub', 'signed_event'], 'properties': {'mode': {'type': 'string', 'default': 'unknown', 'description': 'What was being attempted â\x80\x94 ``"send"``, ``"read"``, or\n``"unknown"``. Recorded for the human reading the logs.'}, 'relay': {'type': 'string', 'description': 'The relay that failed. Must already be in the DPYC set â\x80\x94\nthis tool re-measures the curated set, it is not a probe-anything\nprimitive that can be aimed at arbitrary hosts.'}, 'signed_event': {'type': 'string', 'description': "A Nostr event signed by ``reporter_npub`` whose content\ncontains the relay URL, created within the last few minutes.\nStateless by design: no challenge is issued first, because a\nchallenge store would not survive this service's recycles â\x80\x94 and\na relay report is most needed exactly when relays are broken."}, 'reporter_npub': {'type': 'string', 'description': "The reporting operator's npub."}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
request_citizenship
Begin the citizen registration process (Operator-owned flow).
This is the **citizen** registration path. Called by the Operator on
behalf of a patron â invokes the Oracle directly. No Authority npub
is required or consulted. The patron's npub is registered as a
Citizen in the DPYC community.
The npub provided here becomes the user's **patron identity** â the
keypair they will use for credit purchases and service access across
all Tollbooth-monetized services.
Not to be confused with **operator** registration, which goes through
the Authority via a Nostr DM delegation request.
Issues a cryptographic challenge that the applicant must sign with
their Nostr private key (nsec) to prove they own the claimed npub.
The nsec never leaves the applicant's device.
Returns a challenge_id, nonce, and signing instructions. The applicant
signs a Nostr event containing the nonce and submits it via
confirm_citizenship within 10 minutes.
Input schema
{'type': 'object', 'required': ['npub', 'display_name'], 'properties': {'npub': {'type': 'string'}, 'display_name': {'type': 'string'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
resolve_authority_for
Resolve the certifying Authority for an operator npub.
Returns the Authority's ``{npub, url, name}`` (from the operator's
``upstream_authority_npub``). Use this after bootstrap to learn â and
verify â which Authority signed your config, without reading GitHub.
Input schema
{'type': 'object', 'required': ['npub'], 'properties': {'npub': {'type': 'string'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
resolve_service
Resolve a DPYC service by ``name`` or ``npub``.
Returns ``{npub, url, name, role, purchase_mode}`` where ``purchase_mode``
is the registry-topology fact ``"certified"`` or ``"direct"`` (not a price).
Supply exactly one of ``name`` or ``npub``.
Input schema
{'type': 'object', 'properties': {'name': {'type': 'string', 'default': ''}, 'npub': {'type': 'string', 'default': ''}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
service_status
Diagnostic: report this service's software versions and runtime info.
Free, unauthenticated. Use to verify deployment versions across the
DPYC ecosystem.
Input schema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
update_operator
Update an existing Operator's registry entry.
Used when an Operator moves to a new MCP endpoint, changes its
display name, or needs to correct a registration. Must be called
by the sponsoring Authority (or any Authority).
Input schema
{'type': 'object', 'required': ['operator_npub'], 'properties': {'service_url': {'type': 'string', 'default': '', 'description': 'New MCP endpoint URL (leave empty to keep current).'}, 'display_name': {'type': 'string', 'default': '', 'description': 'New display name (leave empty to keep current).'}, 'operator_npub': {'type': 'string', 'description': 'Nostr npub of the Operator to update.'}, 'authority_npub': {'type': 'string', 'default': '', 'description': 'npub of the requesting Authority (must be a\nregistered authority or prime_authority).'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'additionalProperties': True}
who_is_first_curator
Identify the First Curator (Prime Authority) of the Certification Chain.
Returns the curator's npub, display name, and member record.
Input schema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
Output schema
{'type': 'object', 'required': ['result'], 'properties': {'result': {'anyOf': [{'type': 'object', 'additionalProperties': True}, {'type': 'string'}]}}, 'x-fastmcp-wrap-result': True}
