This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.

This server publishes 1 more address. The block above uses the one we reach during checks; the full list is under Endpoints below, and the author may intend a particular one for your client.

Available tools 31

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

cotlet
cotlet_apps
The apps of the user's workspace and whether each works now: access granted or requested, the app account in the user's Cloud Browser (connected, signed out, signed in but not connected), and the one step the user has to take, with the console link. Free. Needs the user's Cotlet API key or sign-in.
cotlet_browser_click
Clicks a link, button or other element of the current page in the user's Partiful Cloud Browser, by its number in the page's element list, and returns the URL and title after the click. It acts as the user on that site. Buttons that pay or buy and buttons on account or sign-in pages are refused. Every started minute of the session costs credits; it ends when closed or 3 minutes after the last call in the browser.
cotlet_browser_close
Ends the session in the user's Partiful Cloud Browser: the browser keeps its cookies, goes to sleep and the per-minute charge stops. Returns the session's minutes and credits.
cotlet_browser_navigate
Opens a public http or https address in the user's Partiful Cloud Browser and returns the URL and title it ended on. Only Partiful pages open. Every started minute of the session costs credits; it ends when closed or 3 minutes after the last call in the browser.
cotlet_browser_open
Wakes the user's Partiful Cloud Browser, a real Chrome hosted on Cotlet and signed in to Partiful as the user. Use it for what the Partiful tools do not cover. Opens `url` when given and returns the page's URL and title. The user watches every step live. Every started minute of the session costs credits; it ends when closed or 3 minutes after the last call in the browser.
cotlet_browser_press
Presses one key on the current page in the user's Partiful Cloud Browser, on the element that has focus: Tab to the next field, Enter to send, Escape to close a dialog or pop-up, arrows to move through a suggestion list. Returns the URL and title after it. Enter on account pages is refused. Every started minute of the session costs credits; it ends when closed or 3 minutes after the last call in the browser.
cotlet_browser_read
Returns the current page of the user's Partiful Cloud Browser: its readable text, up to 20,000 characters, and a numbered list of its links, buttons and fields. Field values, cookies and storage are never returned. On a page longer than that, both start near where it is scrolled to. Every started minute of the session costs credits; it ends when closed or 3 minutes after the last call in the browser.
cotlet_browser_screenshot
Returns a JPEG image of the visible part of the current page in the user's Partiful Cloud Browser, with its URL and title: boards, canvases and layouts that the page text does not show. Every started minute of the session costs credits; it ends when closed or 3 minutes after the last call in the browser.
cotlet_browser_scroll
Scrolls the current page in the user's Partiful Cloud Browser with the mouse wheel, as a person does: down or up by `screens` viewport heights (default 0.8), to the top or the bottom, or until element `element` is in view. Content that loads on scroll appears, and the next read lists it. Returns the URL, title and scroll position (at_top, at_bottom). Every started minute of the session costs credits; it ends when closed or 3 minutes after the last call in the browser.
cotlet_browser_select
Chooses an option of a drop-down list on the current page in the user's Partiful Cloud Browser, by the list's number in the element list and the option's label as read lists it (or its value). Returns the URL and title after it. Card fields and account pages are refused. Every started minute of the session costs credits; it ends when closed or 3 minutes after the last call in the browser.
cotlet_browser_type
Types text into a field of the current page in the user's Partiful Cloud Browser, by the field's number in the page's element list, and with `submit` presses Enter. Returns the URL and title after it. Password, card and one-time code fields and sign-in pages are refused: the user fills those in themselves. Every started minute of the session costs credits; it ends when closed or 3 minutes after the last call in the browser.
cotlet_browser_upload
Puts files into a file field of the current page in the user's Partiful Cloud Browser, or into the file picker that an upload button opens, by its number in the element list. A file is given as {"url": "https://..."} for a file online or {"file_id": "..."} for one uploaded to Cotlet first; up to 10 files, 20 MB each. Returns the URL and title after it. Every started minute of the session costs credits; it ends when closed or 3 minutes after the last call in the browser.
cotlet_get_call
Status of an earlier Cotlet call, by its call_id: pending (waits for the owner's approval in the Cotlet console), approved, running, success, rejected, expired, blocked or failed. For a call that answered with status pending or running.
cotlet_report_issue
Sends a report straight to the Cotlet team: a tool that failed or returned wrong data, an error you could not get past, or a tool, field or app the task needed and Cotlet lacks. The report carries the error text and call_id when there is one, never passwords or tokens. Needs the user's Cotlet API key or sign-in.
cotlet_request_apps
Requests access to apps for the user's workspace, as Request access in the console: a live app is granted at once, any other goes to the Cotlet team, who answer within 72 hours. Takes app slugs as listed at https://cotlet.dev/api/v1/apps. Free. Needs the user's Cotlet API key or sign-in.
cotlet_upload_file
Returns a one-time upload_url and a file_id for a local file (an image for a post, an attachment). The file is sent to upload_url with an HTTP PUT; an argument that takes a file accepts {"file_id": "..."}. Up to 25 MB, the URL works once. Free. Needs the user's Cotlet API key or sign-in.
cotlet_whoami
The Cotlet account this connection acts as: email, workspace, access status, the API key or OAuth client in use with its scope, the apps the workspace may call and its credit balance. Free. Needs the user's Cotlet API key or sign-in.
event
create_event
New event page. Nobody is invited until you call invite_guests. Creates and publishes an event page hosted by this account, as Create on partiful.com does, with Partiful's default theme. It is private (only people with the link) unless visibility is public. Nobody is invited or texted; share url or call invite_guests. Times without an offset are read in timezone. Guest Approval and a guest limit exclude each other, so a call with both is refused. Returns the new event.
delete_event
Delete an event you host for everyone, with its guest list. Deletes the event as Delete event in its settings does: the page, guest list, photos and messages are gone for everyone and cannot be restored. Guests who RSVPd may be told by Partiful. To keep the page and tell guests, use cancel_event. Hosts only. By default you confirm each call; you can switch that off for this tool. Waits for the owner's approval.
get_event
Full event: title, description, start and end, location, RSVP deadline, guest limit, Guest Approval and waitlist settings, link. Returns one event as its page shows it to the host, with guests per RSVP status and the Guest Questionnaire questions. Times are in the event's time zone. Works for any event the account can open; the write tools need an event it hosts.
update_event
Change the details or settings of an event you host. Changes only the fields you give, as the event's Edit page and settings panel do: title, times, time zone, location, description, RSVP deadline, guest limit, Guest Approval and the Guest Questionnaire. Fields left out keep their value; a call with no field is refused. Turning Guest Approval on removes the guest limit and the waitlist, and the first guest limit turns the waitlist on. New questions replace the questionnaire for guests who RSVP from then on. Returns the event after the change, with updated listing the fields you gave. Hosts only.
guests
check_in_guests
Mark guests as checked in at the door, or undo it. Checks the given guests in, as the host's check-in list does, or takes the check-in back with undo. Guests get no message. Ids that are not on the guest list are refused. Returns how many guests changed and how many are checked in now. Hosts only.
list_guests
Guests of an event with RSVP status, check-in and Guest Questionnaire answers. Returns the guest list the host sees, oldest RSVP first: name, RSVP status, party size with plus-one names, check-in, RSVP note and questionnaire answers. Hosts only. going includes guests approved on a Guest Approval event. guest_id goes to approve_guests and check_in_guests; total counts the guests that match the filters.
approve
approve_guests
Approve pending guests on a Guest Approval event. Moves the given pending guests, or all of them, to Approved, as Approve on the host's guest list does. Partiful tells each approved guest by text or email. Ids that are not pending are refused before the call waits for your approval. Returns how many were approved and how many still wait. Hosts only. By default you confirm each call; you can switch that off for this tool. Waits for the owner's approval.
cancel
cancel_event
Cancel an event. Partiful notifies the guests. Cancels the event as Cancel event on its page does: the page stays up marked canceled. By default Partiful texts the guests on the list with your message, so this reaches real people; notify_guests false cancels without telling anyone. An event that is already canceled is refused. It cannot be undone here. Hosts only. By default you confirm each call; you can switch that off for this tool. Waits for the owner's approval.
duplicate
duplicate_event
Copy an event with its settings to a new date. The copy has no guests yet. Makes a copy as Duplicate on the event page does: title, description, location, theme, questionnaire and RSVP settings, no guests and no messages. The copy starts at start_at and keeps the original's length; Partiful does not copy the RSVP deadline. Nobody is invited. Returns the new event. Hosts only.
events
list_events
Events you host, with date, status and guest counts. Returns the events this account hosts or cohosts, as the Hosting tab of the home page lists them: start and end in the event's time zone, active or canceled, and guests per RSVP status. Events you were only invited to are left out. Upcoming come soonest first, past most recent first. Use event_id in the other tools.
export
export_guest_list
The guest list as CSV, the same file as the Export CSV button. Returns the file the host's Export CSV button downloads, for the chosen RSVP statuses. Columns are Partiful's: Name, Status, Checked in, Check-in Time, RSVP date, then one column per Guest Questionnaire question. Status is Partiful's label, for example Approved on a Guest Approval event. The file text comes back in csv, not as a link, with rows (guests in the file) and a suggested filename. The file has no guest ids, emails or phone numbers; for guest ids use list_guests. Hosts only.
invite
invite_guests
Invite past guests and mutuals through Partiful, or anyone by email. Sends invites as the host's Invite screen does, so they reach real people: Partiful users from list_past_guests get Partiful's invite, people in emails get an email with the event link and your note. There is no way to invite a phone number: Partiful takes phone contacts only in its app. Email invitees still sign in with a phone number to RSVP. Partiful allows 1,000 invites per event, 500 of them by email. A canceled event is refused. invited_total is the event's Invited count after the call. Hosts only. By default you confirm each call; you can switch that off for this tool. Waits for the owner's approval.
past
list_past_guests
People you can invite: your past guests and mutuals. Returns the people Partiful offers on an event's Invite screen: past guests of your events and mutuals from events you went to, with how many events you shared. Give not_on_event_id to leave out people already on that event; there is no filter by one past event. query matches part of the name. user_id goes to invite_guests. A new account has nobody yet, and shared_events or last_shared_event stay 0 or null when Partiful leaves them out.
send
send_text_blast
Text a message to guests by RSVP status. Partiful allows up to 10 Text Blasts per event. Sends a Text Blast as the host's Send Text Blast does: by text and email to every guest with the chosen RSVP statuses, push for guests with the app, and shown in the event's feed unless show_on_event_page is false. Real people get it at once and it cannot be taken back. Up to 480 characters. recipients and by_status count the guests with those statuses at the moment of sending; a choice that reaches nobody is refused before you confirm. Partiful allows 10 blasts per event and refuses a blast to Invited when that group holds more than 100 guests. The answer does not say how many blasts are left. Hosts only. By default you confirm each call; you can switch that off for this tool. Waits for the owner's approval.

Partiful by Cotlet — questions

Answers built from our own checks of this server.

What can Partiful by Cotlet do?
It exposes 31 tools, read directly from the server on our last check. Among them: approve_guests, cancel_event, check_in_guests, cotlet_apps, cotlet_browser_click, cotlet_browser_close and 25 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 Partiful by Cotlet mostly used for?
Its tools cluster around cotlet, event and guests. 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 Partiful by Cotlet working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 182 of 182 checks got a reply (100.0%), average response time 263 ms. The bar chart above shows every period we have measured.
Did Partiful by Cotlet ever remove tools?
Yes. cotlet_balance, cotlet_browser_connect, cotlet_browser_sessions are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
How do I connect Partiful by Cotlet?
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. You sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.
How do you sign in to Partiful by Cotlet?
No API key is involved. Partiful by Cotlet answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.
How fast is Partiful by Cotlet?
It answers our handshake in 263 ms on average, which is faster than 64% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Partiful by Cotlet?
The pypi package partiful-api-mcp was installed 522 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Partiful by Cotlet open source?
We cannot say either way: written in Python and 2 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
