List Gmail threads.

Read a Gmail thread.

Search issues by text, across titles and descriptions. Set include_comments to search inside comments too. This is full-text search; to filter on fields such as state or assignee, use issues_list.

Create an issue. team_id and title are required; everything else is optional. The UUIDs for team, assignee, state and labels come from teams_list, users_list and workflow_states_list — Linear does not accept names here. Set parent_id to create a sub-issue.

Save an email draft to Gmail.

Modify the labels on a thread, and so on every message in it.

List issues, optionally filtered. Conditions on one filter object combine with AND. To find a team's open work, filter on team.key and state.type.

List attachments — the links between Linear issues and things outside it.

Retrieve a single customer by ID.

List invoices, most recently created first. Filter by customer, subscription, status or collection method.

List customer requests. Filter by issue to see what a piece of work is wanted for, or by customer to see everything one company has asked for.

List meeting notes, filtered by when they were created or last updated and optionally narrowed to one folder and its subfolders. Returns each note's id, title, owner and timestamps, not its content. Fetch that with notes_get. Only notes that already have a generated AI summary appear here.

Create a blank document with a title. Only the title is honoured — the document is created empty. To add content, call this and then documents_batch_update with the returned documentId.

List subscriptions. Filter by customer or status.

Send a message to a Slack channel, private group, or DM. Provide text for a plain message; set thread_ts to reply inside an existing thread.

Create a calendar event; returns details of the event.

Create a copy of a file and apply any requested updates with patch semantics. Typically send a new name and optionally parents.

Create a permission for a file or shared drive. type is user, group, domain or anyone; role is owner, organizer, fileOrganizer, writer, commenter or reader. For user or group, send emailAddress. Concurrent permission writes on the same file are not supported.

Send an email via the Gmail API.

Fetch recent messages from a Slack channel.

Record a customer request, optionally attached to an issue or project. This is the one Linear mutation whose reply carries no object — it answers only with whether it worked.

List customers, most recently created first. Filter by email to find one.

List charges, most recently created first.

Refund a charge. Provide either charge or payment_intent. Omit amount to refund the full sum.

List a form's submitted responses, newest page first, up to 5000 per page. The only supported filter is on submission time: pass filter='timestamp >= 2026-01-01T00:00:00Z' to read what has arrived since a point in time. Answers come back keyed by questionId.

Search the titles of pages and data sources shared with this integration. Titles only — it does not search page content — and it returns nothing that has not been shared. With no query it lists everything visible, which is how you find the IDs to start from.

Create a page — as a subpage of another page, or as a row of a database by giving its data_source_id as the parent. Content comes as a markdown string Notion parses into blocks, or from a template: one or the other, never both.

Update an issue. Only the fields provided are changed. To close an issue, set state_id to a state whose type is 'completed' or 'canceled' — Linear has no separate close operation. Use added_label_ids and removed_label_ids to adjust labels; label_ids replaces them outright.

List the user's files. Returns all files by default, including trashed files; add trashed = false to q to hide them. q is Drive's search grammar — name contains 'Q3' and mimeType = 'application/vnd.google-apps.folder'.

Sets values in a range of a spreadsheet.

Connect one app this server uses. For an app that issues keys, says where to get one and the terminal command that stores it. For Google, once the user's own OAuth client is set, starts the browser sign-in and returns at once: the user approves in the browser and the next call works. To see which apps are connected, call connection_status. Never ask the user for a key in the chat.

See which apps this server is connected to, and how to connect each one that is not. Changes nothing.
