Install

How do I install the ClusterHack MCP server?

ClusterHack is a hosted endpoint at https://clusterhack.dev/mcp/, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 60 exposed · ~6,274 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
team_locations ~91

Read 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`.

NameTypeReqDescription
team_idintegeryesId of the team.

No output schema declared.

No examples provided.

team_matchmaking_teams ~122

AI-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.

NameTypeReqDescription
free_member_idintegeryesId of the free-agent listing.
localestringLanguage for the generated explanations, e.g. 'en' or 'ru'.

No output schema declared.

No examples provided.

team_members ~90

List 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`.

NameTypeReqDescription
pageintegerPage number, starting at 1.
page_sizeintegerRows per page (max 100).
team_idintegeryesId of the team.

No output schema declared.

No examples provided.

team_open_roles ~267

List 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` and `team_matchmaking_teams`). Filter with `team_id` for one team, or `event_slug` to see everything the caller can see at that event. `team_id` is answered exactly. `event_slug` (and the unfiltered form) is not: the underlying endpoint narrows by one team at a time and has no event filter, so a very large event can return a `note` saying rows were left unscanned. Ask per team when that matters.

NameTypeReqDescription
event_slugstringOnly open roles at this event (within what the caller can see).
pageintegerPage number, starting at 1.
page_sizeintegerRows per page (max 100).
team_idintegerOnly this team's open roles.

No output schema declared.

No examples provided.

team_posts ~113

List 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`.

NameTypeReqDescription
pageintegerPage number, starting at 1.
page_sizeintegerRows per page (max 100).
team_idintegeryesId of the team.

No output schema declared.

No examples provided.

team_readiness ~44

Check whether a team has marked itself ready to present, plus whether it is banned or currently accessible for judging.

NameTypeReqDescription
team_idintegeryesId of the team.

No output schema declared.

No examples provided.

team_roles ~78

List the roles a team has defined (e.g. "Frontend", "Designer"), which members can be assigned via `team_assign_role`.

NameTypeReqDescription
pageintegerPage number, starting at 1.
page_sizeintegerRows per page (max 100).
team_idintegeryesId of the team.

No output schema declared.

No examples provided.

team_seeking_members ~207

Browse 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 organise the event) and shows a stranger nothing. Each row here carries the team's public profile plus its `open_roles`. Follow up with `team_request_join`, or list yourself with `event_join_as_free_agent` if nothing fits.

NameTypeReqDescription
event_slugstringyesSlug of the event.
pageintegerPage number, starting at 1.
page_sizeintegerRows per page (max 100).
searchstringFree-text filter over team name and description.

No output schema declared.

No examples provided.

tech_list ~61

List technologies (tech-stack tags) that projects and teams can be labelled with, e.g. "React", "PostgreSQL".

NameTypeReqDescription
pageintegerPage number.
page_sizeintegerResults per page (max 100).

No output schema declared.

No examples provided.

whoami ~128

Who 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 decide which tools apply before calling anything else, and to resolve "my event" / "our team" into a concrete slug or id.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

Common questions

What is the ClusterHack MCP server?

ClusterHack is an MCP server listed in the public MCP registry as dev.clusterhack/clusterhack. Run hackathons end to end: events, teams, submissions, judging and winners. This page covers its hosted endpoint (https://clusterhack.dev/mcp/).

Is the ClusterHack MCP server safe to use?

ClusterHack scores 87 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the ClusterHack MCP server expose?

ClusterHack exposes 60 tools: event_roles, list_api_endpoints, list_capabilities, search, server_info, and 55 more. Their descriptions and schemas cost roughly 6,274 tokens of context every time the server is loaded.

Does the ClusterHack MCP server require authentication?

No. We connected to ClusterHack without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the ClusterHack MCP server still maintained?

ClusterHack is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
