Available tools 78

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

event

create_event

Create an event. Requires title, start_date and end_date (ISO 8601, e.g. 2025-09-21T09:00:00Z) and team_id (get from list_teams). location optional.

delete_event

Delete an event (removes it from listings; payments preserved for audit).

get_event

Get one event by id (modules, email settings, dates, billing). Speakers, sponsors and schedules are separate tools — see the Actions dashboard via get_event_actions.

get_event_actions

One call returning everything actionable on an event: speakers/sponsors awaiting intake approval or card approval/publishing, call-for-speakers applications, and schedule pending proposals + publishable tracks. Replaces five separate list calls; use this when asked 'what needs doing on <event>'.

get_event_modules

List an event's modules with their enabled state (speaker, schedule, content, attendee, app).

list_event_members

List the people with direct access to an event: user_id, name, email, role ('event:admin'/'event:editor'/'event:viewer'/'speaker'), invitation status ('active'/'pending').

remove_event_member

Remove a member's access to an event (their speaker links are not affected). Get user_id from list_event_members.

set_event_image

Upload an image for an event (e.g. hero/banner) and set it as the event's eventImage. `source` is a public image URL (fetched by this server, e.g. Drive link or website) or a base64 data URL. Replaces any existing image.

update_event

Update an event. Pass only the fields to change (title, start_date, end_date, location, website). The event image is set with set_event_image.

update_event_member

Change a member's role: 'admin' (full control), 'editor' (manage content) or 'viewer' (read-only). Get user_id from list_event_members. The event creator cannot be demoted.

sponsor

create_sponsor

Create a sponsor for an event. Requires company_name and sponsor_type (a sponsor category — pick from list_sponsor_categories, e.g. 'gold_sponsor'; custom values are also fine and become available event-wide). Primary contact name/email recommended. Logos are uploaded separately later.

delete_sponsor

Delete a sponsor from an event. Permanent — removes their logo, links and card images.

get_sponsor

Get one sponsor by id (company info, contacts, logos, status).

list_sponsor_categories

List the sponsor categories available for create_sponsor/update_sponsor. Defaults (e.g. 'gold_sponsor') plus any custom categories already in use on the event when event_id is given.

update_sponsor

Update a sponsor. Pass only the fields to change (snake_case names). sponsor_type takes a category value from list_sponsor_categories. primary_contact_email is frozen by the API (it owns the sponsor account). Set website_card_approved / promo_card_approved true to publish the sponsor's cards to the website walls.

marketing

create_marketing_poster

Create a saved marketing poster (a grid of cards for the Marketing Builder). kind fixes the entity type: 'speakers', 'sponsors' or 'attendees'. entity_ids are the ids of the entities to show on the poster (get them from list_speakers/list_sponsors/list_attendees). cols_desktop/cols_mobile are grid columns; png_cols is the cards-per-row used for PNG export; card_urls carries hosted card PNGs ({fp: templateFingerprint, urls: {cardId: url}}).

delete_marketing_poster

Delete a marketing poster by id.

list_marketing_posters

List an event's saved marketing posters (poster grids of speaker/sponsor/attendee cards, newest first).

update_marketing_poster

Update a marketing poster. Pass only the fields to change: name, entity_ids (replaces the poster's cards), cols_desktop, cols_mobile, png_cols, card_urls. kind is fixed at creation and cannot change — create a new poster for a different entity type.

schedule

create_schedule

Create a schedule (track) for an event. Optional name (default 'Event Schedule'), schedule_type (default 'detailed') and location.

delete_schedule

Delete a schedule (track) and all its activities and versions.

get_schedule

Get one schedule by id (with its activities).

update_schedule

Update a schedule (track): name, schedule_type or location. Activities are managed separately.

speaker

create_speaker

Create a speaker for an event. Requires first_name, last_name, email. The speaker is coupled to the event; image files can be added later with upload_speaker_image.

delete_speaker

Delete a speaker from an event. Permanent — removes their talk links, content and images.

get_speaker

Get one speaker by id (bio, talk title, headshot, logos, links).

update_speaker

Update a speaker. Pass only the fields to change (snake_case names). For images use upload_speaker_image instead of headshot/company_logo. Set website_card_approved / promo_card_approved true to publish the speaker's cards to the website walls.

activity

create_activity

Create a session (activity) in a schedule. Requires title; optional dates/times (ISO, e.g. start_date 2025-09-21, start_time 10:00:00), description, location, notes, and speaker_ids/sponsor_ids to link speakers or sponsors to the session.

delete_activity

Delete an activity (session) from a schedule.

update_activity

Update a session (activity). Pass only the fields to change; setting speaker_ids/sponsor_ids replaces the linked speakers/sponsors.

chat

delete_chat_message

Delete a chat message (your own; organisers can delete any).

list_chat_conversations

List the logged-in user's DM threads for an event (one row per peer, latest message first). Pass a conversation's peerId to list_chat_messages as `peer` to read the full thread.

list_chat_messages

List chat messages for an event-wide channel (oldest last). Optional `peer` for a DM thread, `after` ISO timestamp to poll for new messages.

upload

upload_entity_content

Attach a content file (slide deck, video, image, PDF…) to a speaker, sponsor or schedule. entity_type picks which. `source` is a public URL (fetched by this server) or a base64 data URL. name is a label shown in the app, e.g. 'presentation' or 'previous_talk'.

upload_speaker_image

Upload an image for a speaker and attach it to a slot (headshot, company_logo or company_logo_white). `source` is a public image URL (fetched by this server, e.g. Drive link or website) or a base64 data URL. Replaces any existing image in that slot. Ask the user whether to auto-crop the image to a face (face_crop) before uploading if they haven't said.

upload_sponsor_image

Upload a logo for a sponsor and attach it to a slot (company_logo, company_logo_white, company_logo_vector or company_logo_white_vector). `source` is a public image URL (fetched by this server, e.g. Drive link or website) or a base64 data URL. Replaces any existing logo in that slot.

attendee

get_attendee

Get one attendee by id (profile, ticket, check-in state).

update_attendee

Update an attendee's details. Pass only the fields to change (first_name, last_name, email, phone_number, company_name, job_title).

attendees

check_in_attendees

Check in attendees in bulk. attendee_ids are ids from list_attendees.

list_attendees

List attendees for an event (paginated). Optional `search` by name/email, `state` filter (e.g. 'complete').

form

get_form_config

Get an event's intake form config (fields + metadata). Optional form_type filter ('speaker-info', 'sponsor-info', 'call-for-speakers'); without it returns the first config.

set_form_config

Create or update an event's intake form config (upsert by event_id + form_type). form_type: 'speaker-info', 'sponsor-info' or 'call-for-speakers'. `config` is the form-builder JSON: {fields: [{id, label, type, enabled, required, options, helpText, sectionStart, maxWords}], metadata: {title, subtitle, showTitle, shareCaption, welcomeInfo: {tabLabel, heading, body}}}.

labels

get_my_labels

Get the logged-in user's areas-of-interest labels for an event (e.g. ['AI', 'Fintech']) — what they're interested in / following there.

set_my_labels

Replace the logged-in user's areas-of-interest labels for an event (the full list replaces the old one — read with get_my_labels first and keep what they want to keep).

news

create_news

Post a news item to an event's news feed (organisers). notify=True (default) also push-notifies everyone linked to the event.

list_news

List news items for an event.

promo

get_promo_config

Get an event's card design config. Optional promo_type filter ('website', 'sponsor-website', 'promo', 'sponsor-promo'); without it returns the event's first config.

set_promo_config

Create or update an event's card design config (upsert by event_id + promo_type). promo_type: 'website' (speaker website cards), 'sponsor-website' (sponsor website cards), 'promo' / 'sponsor-promo' (social share cards). Pass either `preset` (a name from list_card_presets) or `config` (the card-design JSON the card builder saves: templateUrl, bgColor, canvasWidth/canvasHeight, field descriptors). embed_expandable + embed_expand_count make the embed wall render the first N cards plus a show-more chevron instead of all cards.

publish

publish_schedule

Publish a schedule (track): snapshots the current draft into a new version — that snapshot is what the app and website render. Publish again after edits.

publish_website

Publish an event's website: snapshots the current draft live (what visitors see). Requires a saved config and a claimed slug — save_website first. Publish again after further edits in the builder to ship them.

send

send_chat_message

Send a chat message to an event's chat channel (as the logged-in user). Optional peer_user_id sends a direct message to that user instead of the event-wide channel.

send_speaker_login_link

Email a speaker a passwordless sign-in link for the ConfBuilder app (their account is created if needed). Use when the user asks to send a speaker their login / access link; confirm the speaker before sending.

website

check_website_slug

Check whether a website-builder slug (the subdomain label, 3–40 lowercase letters/numbers/hyphens) is valid and available, e.g. before save_website claims it.

get_website

Get an event's website-builder state: config (the section/theme draft JSON), slug (claimed address, e.g. summit2026 gives summit2026.confbuilder.com), publishedConfig + publishedAt (what is live). config null = website not started.

accept_event_invitation

Accept the logged-in user's own pending invitation to an event (activates their membership). Use when the user says 'accept my invite to <event>'.

activities

list_activities

List activities (sessions/talks) in one schedule.

ConfBuilder — questions

Answers built from our own checks of this server.

What can ConfBuilder do?

It exposes 78 tools, read directly from the server on our last check. Among them: accept_event_invitation, archive_entity_content, check_in_attendees, check_website_slug, create_activity, create_checkout and 72 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is ConfBuilder mostly used for?

Its tools cluster around event, sponsor and speaker. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is ConfBuilder working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 101 ms. The bar chart above shows every period we have measured.

How do I connect ConfBuilder?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does ConfBuilder need an API key?

No. ConfBuilder completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 78 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is ConfBuilder?

It answers our handshake in 101 ms on average, which is faster than 92% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
