event_rolesread-onlyWhich roles the signed-in user holds at one specific event. Cheaper and more precise than `whoami` when you already know the event and just need to know whether the user can organise, judge or only take part.
list_api_endpointsread-onlyList the raw REST endpoints behind this server. Use it together with `api_request` when you need something no curated tool covers. The list is read from the live URL configuration, so it always matches what the server actually serves.
list_capabilitiesread-onlyThe catalogue of everything this server can do, grouped by area. Returns each tool available to the current connection with its one-line purpose, the role it is meant for and the permission it consumes. Use it when you are not sure a capability exists — it is cheaper than guessing tool names, and it shows what the user would gain by granting more permissions.
searchread-onlySearch across the platform: events, teams, projects, people and articles. One call when you do not yet know the identifier of the thing the user means ("the AI hackathon in Berlin", "Sasha's team"). Returns the matching objects with the slug or id you need for every other tool.
server_inforead-onlyWhat this MCP server is, which version it speaks, and how to connect. Useful for diagnostics and for telling the user where to manage or revoke the connection.
whoamiread-onlyWho is signed in, what roles they hold, and where. Call this first in any new conversation. It returns the account, the OAuth permissions this connection was granted, and — crucially — the list of events, teams and companies the user belongs to *with the role they hold in each one* (organizer, judge, participant, team lead, free agent, builder, speaker, company admin, platform admin). Use it to
event_background_imagesread-onlyThe global catalogue of certificate background templates (used for the `background` field of an event's certificate config). Not tied to one event.
event_citiesread-onlyThe global catalogue of cities (used for the `city` field on `event_create`/`event_update` and to show where events happen).
event_faqread-onlyAn event's FAQ: the question/answer pairs shown on its public page. Public read — use it to answer a participant's question from the event's own words before guessing, and to check what is already covered before adding more.
event_getread-onlyGet one event's full public profile by slug: name, dates, address, topic, description, status and city. Call this once you have a slug (from `event_list` or `search`) and need the details. It does not include the schedule, FAQ or nominations — use `event_schedule`, `event_faq` and `event_nominations` for those.
event_info_blocksread-onlyAn event's additional free-form information blocks (extra sections shown on its public page beyond the main description — rules, prizes, sponsors notes, etc.).
event_listread-onlyBrowse hackathons on the platform — filter by status, city or date. Returns each event's slug, which every other event tool needs, plus name, status, dates and city. Use this when the user names an event you do not have a slug for and `search` is not precise enough, or to show a list of upcoming/past events. Hidden events only appear here for their own organisers.
event_nominationsread-onlyAn event's award nominations/tracks (e.g. "Best AI prototype"), used when creating teams, awarding winners and building the leaderboard per track.
event_presetsread-onlyPublic catalogue of event-creation presets (AI build day, student hackathon, corporate innovation day, ...) with sensible defaults and starter nominations. Call before `event_create` when the user describes a kind of hackathon rather than exact field values.
event_scheduleread-onlyThe event's timeline: an ordered list of stages/activities (opening, workshops, deadlines, closing ceremony) with title, location, time window and status (past/now/future). This is what participants see as "the schedule". Broadcast link and chat link are only included for the event's admins and registered participants — everyone else sees them blanked.
event_share_linksread-onlyThe public links for promoting an event: its shareable page, the calendar file participants can add to their own calendar, the Open Graph preview image used when the link is pasted into chat, and a plain-text digest meant for AI assistants. Handy when drafting an announcement — put the share URL in the post and the .ics next to the date. Public read.
event_team_stagesread-onlyAn event's team-facing reporting checkpoints (e.g. "Idea locked", "Demo ready") with their time windows — distinct from `event_schedule`, which is the event's own agenda. Used to track team progress through the event.
event_typesread-onlyThe global catalogue of event types (used for the `type` field on `event_create`/`event_update`). Small and rarely changes.
event_brandingread-onlyRead an event's white-label branding: brand colours, public-page theme and dedicated subdomain, plus the resolved values actually used for rendering and `branding_enabled` — whether the evening currently wears its costume, i.e. whether those values are applied. Public, because the colours are visible on the event page anyway. Use it before `event_set_branding` to see what is already set.
event_free_agentsread-onlyList participants at an event who are looking for a team. Visibility follows the platform's own rule, not a full public roster: a normal caller only sees their own free-agent listing here, while an organiser of the event sees everyone's. Use `team_matchmaking_teams` on a listing's id for AI-ranked team suggestions for that person.
event_my_membershipread-onlySummarise the signed-in user's relationship to one event: whether they have joined, their registration answers on file, whether they are listed as a free agent, and which roles they hold there (organizer, judge, team lead, ...). Cheaper than combining several other tools when you just need "is this user in, and how" for one event.
event_my_registration_answersread-onlyList the signed-in user's own answers to one event's registration questions. Only ever returns their own data — use `event_registration_responses` (organiser only) to read other people's.
event_registration_formread-onlyList the custom questions an event asks at registration time (its registration form), in display order. Public data — the question text is visible to anyone. Use this before `event_submit_registration_answers` to know which `form_field_id`s exist and which are required.
invite_previewread-onlyLook up what a shareable invite link opens, without redeeming it. Public and PII-free: returns the event's name and slug and whether the token is still valid (active, not expired, uses remaining). Use this before `invite_join` to show the user what they are about to join, or to explain why a link stopped working.
team_getread-onlyGet one team's full detail: name, description, project info, readiness, accessibility flags, and which event and nomination it belongs to. Only visible if the signed-in user belongs to the team, created it, or administers its event.
team_listread-onlyList teams — scoped to what the signed-in account can see: teams they belong to, created, or administer via being an admin of the team's event. This is never a full public directory of every team on the platform. Filter by `event_slug` to see just one event's teams, or `search` to match team/project name and description. Use `team_get` for the full detail of one team once you have its id.
team_locationsread-onlyRead the physical location details linked to a team's additional-info profile (street, city, state, zip), if one has been set. There is currently no self-service way to create a new location through this API — location rows are set up separately, then referenced by id via `team_additional_info`'s `location_id`.
team_matchmaking_teamsread-onlyAI-ranked list of teams one free (teamless) participant could join, within the same event. Callable by the free-agent listing's own owner, or an admin of the event. Use `event_free_agents` or `event_join_as_free_agent` to get a `free_member_id`. Throttled — do not call it in a tight loop.
team_membersread-onlyList a team's current members with their role and caption. Use the row `id` (a membership id, not a user id) with `team_assign_role` or `team_remove_member`.
team_open_rolesread-onlyList the positions teams are looking to fill ("we need a designer"). Visibility is limited to what the signed-in account can already see: their own team's open roles, or — if they organise the event — every team's. It is not a public cross-team browse for a stranger looking for any team: that is `team_seeking_members`, which reads the find-a-team page's own list (pair it with `event_free_agents`
team_postsread-onlyList a team's public updates ("twits") — the short build-log posts a team publishes as it works, in the order the server returns them. Use it to catch up on what a team has been doing, or to check what has already been posted before writing another update with `team_post`.
team_readinessread-onlyCheck whether a team has marked itself ready to present, plus whether it is banned or currently accessible for judging.
team_rolesread-onlyList the roles a team has defined (e.g. "Frontend", "Designer"), which members can be assigned via `team_assign_role`.
team_seeking_membersread-onlyBrowse the teams of one event that are advertising open positions — the public "who is recruiting" list behind the find-a-team page, readable by anyone, including someone who has not joined the event yet. This is the tool for a person looking for a team. `team_open_roles` is the other direction: it lists open positions the caller already has access to (their own teams', or every team's if they or
submission_getread-onlyRetrieve one project submission by id: title, links, description, status, approval status, vote count and attached media. Anonymous and unrelated callers only see it once the team has submitted (status "submitted"); drafts are visible only to the team, the event's admins and its judges. Use `submission_list` or `submission_get_mine` when you do not already know the numeric id.
submission_listread-onlyBrowse project submissions, filterable by event, team or status. Anonymous and unrelated callers only ever see submitted (public) projects; a signed-in caller additionally sees their own team's drafts and every submission at events they administer or judge. ``status`` narrows the returned page client-side (draft / submitted / disqualified) since the underlying list endpoint does not filter by sta
submission_list_mediaread-onlyList the screenshots/gallery images attached to a submission. Visibility mirrors the parent submission: public once submitted, otherwise limited to the team, event admins and judges.
submission_pageread-onlyRead a project's public page: the submission itself, every judge's written feedback (signed with the judge's name only where that judge consented to being named, empty otherwise), and — once the organiser has published the winners — its placement, rank and judge score. This is the tool for "what did the judges say about our project?". `submission_get` returns the project's own fields and nothing
event_leaderboardread-onlyThe ranked leaderboard for one event: submissions ordered by weighted judge score then vote count, with each entry's rank, team and score. Public once the organiser publishes winners; before that, only the event's admins and judges can preview it (everyone else gets a clear "not published yet" error).
showcase_browseread-onlyBrowse the public, cross-event showcase: shipped/submitted projects ranked for display, with title, tagline, team name, vote count and a cover image. Optionally narrow to one event. This is the public gallery — use `event_leaderboard` instead when you specifically need judged rankings for one event.
company_about_usread-onlyA company's longer "about us" blurb (up to 10,000 characters), separate from its short `description`. Returns `found: false` if the company has not written one yet.
company_employeesread-onlyA company's employee roster (position, start date). Without `company_id`, returns every roster row the caller can see (their own employment rows plus every company they administer) — the underlying API is already scoped that way. With `company_id`, narrows to that company only.
company_employment_requestsread-onlyPending requests to join a company. A company admin sees everyone waiting on their door; anyone else sees only their own outstanding applications. This is where the `request_id` for `company_decide_employment_request` comes from.
company_ex_employeesread-onlyA company's former employees (position, start and end date) — the record created when someone is fired via `company_fire_employee`. Without `company_id`, returns every ex-employment row the caller can see (their own, plus every company they administer).
company_getread-onlyOne company page by id: name, description, organisation type, website and logo. Public read. Use it after `company_list` or `search` to get the full record, and to confirm you have the right company before employment or sponsorship actions, which are irreversible for the people involved.
company_listread-onlyBrowse ClusterHack company pages: name, description, org type, website and logo. Public data — use this to find a company's id before calling any other company tool.
company_rosterread-onlyThe company page's public roster in one call: the people listed as employees and the people listed as moderators, exactly as the company page renders them to any visitor. Use this — not `company_employees` / `company_admins` — whenever you want to read *someone else's* roster. Those two are scoped to self-or-admin, so an outsider gets an empty list from them and cannot tell "nobody works here" ap
company_vacanciesread-onlyThe public board of companies not yet on ClusterHack (a lightweight off-platform listing — name, description, website — not a job-posting system). Public, no filters.
event_sponsor_textread-onlySponsors of one event that are NOT themselves on ClusterHack (a name, description, website and logo entered as free text, with the sponsorship tier each one belongs to) — the off-platform counterpart to `event_sponsors`. Public read.
event_sponsor_tiersread-onlyThe sponsorship tiers/groups defined for one event (e.g. "Sponsors", "Partners", "General Partner") — the buckets `event_add_sponsor` slots companies into. Public read.
event_sponsorsread-onlyThe on-platform companies sponsoring one event, with the sponsorship tier each one is slotted into (e.g. "Sponsors", "Partners", "General Partner"). Public read. Use `event_sponsor_text` alongside this for sponsors that are not themselves on ClusterHack yet.
article_getread-onlyRetrieve one CMS article by id: its body, publish date, hidden flag, and which title/slug and language it belongs to.
article_languagesread-onlyList the languages articles can be written in, e.g. {"language_name": "English", "short_name": "en"}. Use this to find the `language_id` `article_create` needs.
article_listread-onlyBrowse CMS articles (the pages under /articles/<language>/<slug>). Filter by `language` (a language's short code, e.g. 'en') and/or `slug` (a title's slug) to find one specific page's translations. Hidden drafts are only included for staff callers; everyone else sees only published articles.
article_titlesread-onlyList the CMS "title" records — each one a page's title text and slug, e.g. {"title": "How to organize a hackathon", "slug": "how-to-organize"}. An article always points at one of these; use this to find the `title_id` `article_create` needs, or to see what pages exist at all.
legal_inforead-onlyThe service's legal identity, as the terms-of-service, privacy and support pages render it: the service and operating entity, whether that entity is registered and where, the contact and privacy email addresses, the postal address, the terms' effective date and the minimum age to hold an account. Read it instead of hard-coding a copy — a client building its own footer, quoting the contact address
tag_listread-onlyList tags used to categorize content across the platform (articles, projects and more share the same tag vocabulary).
tech_listread-onlyList technologies (tech-stack tags) that projects and teams can be labelled with, e.g. "React", "PostgreSQL".
account_ai_accessread-onlyHow the signed-in user sees and revokes AI access to their own account — read this instead of looking for a tool that lists or cuts off connected clients, because there is deliberately no such tool. The controls over AI access (list connected clients, revoke one, list and end live MCP sessions, read the record of what a client did as them) are gated to the account holder signing in directly: a br
account_how_to_sign_inread-onlyExplains how to connect an account to this MCP server — read this instead of guessing at a login/registration tool, because there isn't one. ClusterHack's own credential endpoints (register, login, JWT issuance, password reset) are the website's login form, not MCP tools: an MCP client authenticates by OAuth 2.1 (the same flow a human approves in a browser tab) and must never see or handle a Clus
