How to connect Linear MCP with Cursor

Retrieve an issue attachment by ID. Use format=url to get its title and download URL without fetching the file content. Linear upload URLs are signed for five minutes; call again to refresh. External URLs are returned unchanged. Files embedded in comments have no issue attachment ID; use the URLs in list_comments attachments instead. Download and process documents with your own file tools.

Prepare a direct Linear file upload for an existing issue. Workflow: 1. Call this tool with issue, filename, contentType, and size. 2. Upload raw bytes with PUT to uploadRequest.url outside MCP. 3. All headers in uploadRequest.headers are part of the signed request, so send them verbatim. 4. After PUT succeeds, call create_attachment_from_upload with assetUrl to link it to the issue. Do not base64-encode or transform the file. Use curl --data-binary @path or fetch(url, { method: 'PUT', body: blob }). Omitting or modifying any signed header, including casing, will return HTTP 403. The signed URL must be used within 60 seconds or it will expire. Upload sequencing: Prepare, PUT, and finalize one file before calling this tool for another file. Do not batch multiple prepare_attachment_upload calls before starting the PUTs because earlier signed URLs can expire while later files are prepared. Example: curl -X PUT --data-binary @file.png \ -H "content-type: image/png" \ -H "x-goog-content-length-range: N,N" \ -H "cache-control: public, max-age=31536000" \ -H 'Content-Disposition: attachment; filename="file.png"' \ "<uploadRequest.url>"

Link an already-uploaded Linear assetUrl to an existing issue as an attachment. Use this only after: 1. prepare_attachment_upload returned an assetUrl and uploadRequest. 2. The client successfully PUT raw file bytes to uploadRequest.url. This tool does not upload file content. It only creates the Linear attachment row. If the direct upload failed or the signed URL expired, rerun prepare_attachment_upload and upload again.

Deprecated fallback for tiny files only. Accepts base64 file content, verifies SHA-256 checksum, and uploads it through the MCP worker. Prefer `prepare_attachment_upload` plus direct PUT plus `create_attachment_from_upload`. CRITICAL: Do not print base64Content and then copy it into this tool call. Opaque base64 copied through model-visible text is easy to corrupt. Generate base64Content mechanically from the source bytes and pass it through a programmatic argument construction path whenever available. Before calling this tool, verify the values are consistent: Unix-like shells: file="/path/to/file" base64Content=$(base64 < "$file" | tr -d '\n\r') sha256=$(shasum -a 256 "$file" | awk '{print $1}') decodedSha256=$(printf '%s' "$base64Content" | base64 -d | shasum -a 256 | awk '{print $1}') size=$(wc -c < "$file" | tr -d ' ') # optional; stat can also get file byte size decodedSize=$(printf '%s' "$base64Content" | base64 -d | wc -c | tr -d ' ') PowerShell: $file = 'C:\path\to\file' $bytes = [IO.File]::ReadAllBytes($file) $base64Content = [Convert]::ToBase64String($bytes) $sha256 = (Get-FileHash -Algorithm SHA256 -Path $file).Hash.ToLower() $size = $bytes.Length # optional $decoded = [Convert]::FromBase64String($base64Content) $decodedStream = [IO.MemoryStream]::new($decoded) $decodedSha256 = (Get-FileHash -Algorithm SHA256 -InputStream $decodedStream).Hash.ToLower() $decodedSize = $decoded.Length decodedSha256 must equal sha256. If you pass size, decodedSize must equal size. Pass `sha256`. Passing `size` is optional, but recommended for clearer mismatch errors.

Delete an attachment by ID

List Linear Agent skills available to the authenticated user.

Retrieve a Linear Agent skill by ID, including its full markdown instructions.

List comments on a Linear issue, project, initiative, document, project milestone, or project/initiative status update. Provide exactly one of `issueId`, `projectId`, `initiativeId`, `documentId`, `milestoneId`, or `statusUpdateId`. For issues, projects, and initiatives this returns both top-level discussion threads and inline description comments. Inline (anchored) comments carry a non-null `quotedText` set to the snippet of description text they reference. Returned comments include `author` and nullable `onBehalfOf`; when set, `onBehalfOf` identifies the user the agent author acted for. Files uploaded in comment bodies are returned in `attachments` with titles and download URLs, not issue attachment IDs. Signed upload URLs expire after five minutes; call list_comments again to refresh them. Download documents using these URLs and process them with your own file tools.

Create or update a comment on a Linear issue, project, initiative, document, project milestone, or project/initiative status update. If `id` is provided, updates the existing comment; otherwise creates a new one. To start a new thread, pass `body` and exactly one of `issueId`, `projectId`, `initiativeId`, `documentId`, `milestoneId`, or `statusUpdateId` — comments on issues/projects/initiatives become top-level discussion threads; comments on documents/milestones become description comments. A status update holds a single thread, so a comment on an update that already has one is added to it as a reply. To reply to an existing thread, pass `parentId` and `body`; the reply inherits the parent's thread type, so no entity reference is needed. Parent reference fields are ignored when `id` or `parentId` is provided (`statusUpdateType` is rejected instead).

Delete a Linear comment. Inline description comments (those with non-null `quotedText`) anchor a mark in the editor, so their root cannot be deleted — delete the replies individually or resolve the thread instead.

Retrieve cycles for a specific Linear team

Find saved issue, project, and initiative views accessible to the user, including personal, workspace, and team views. Excludes archived views and views scoped to a project or initiative. Returns view metadata, not the records matching its filters.

Retrieve a Linear document by ID or slug

List documents in the user's Linear workspace

Create or update a Linear document. If `id` is provided, edits the existing document; otherwise creates a new one. When creating, `title` is required and exactly one parent (`project`, `issue`, `initiative`, `cycle`, or `team`) must be specified. On update, passing a parent reparents the document. To change parts of the content without resending all of it, pass `patch` instead of `content`.

Extract and fetch images from markdown content. Use this to view screenshots, diagrams, or other images embedded in Linear issues, comments, or documents. Pass the markdown content (e.g., issue description) and receive the images as viewable data.

Retrieve detailed information about an issue by ID, including attachments, git branch name, and active Triage Intelligence suggestions when the issue is in triage

List issues in the user's Linear workspace, including active Triage Intelligence suggestions for issues in triage. For my issues, use "me" as the assignee. Use "null" for no assignee.

Create or update a Linear issue. If `id` is provided, updates the existing issue; otherwise creates a new one. When creating, `team` is required, and `title` is required unless `template` is set. Note: use `assignee` (not `assigneeId`) to set the assignee — it accepts a user ID, name, email, or "me".

List available issue statuses in a Linear team

Retrieve detailed information about an issue status in Linear by name or ID

List available issue labels in a Linear workspace or team. A retired label carries `retiredAt` and cannot be applied to new issues.

Create a new Linear issue label. Deprecated: use `save_issue_label`, which can also update labels.

Retire a Linear issue label so it cannot be applied to new issues. The label stays visible on issues that already have it. Retiring a label group also retires its child labels. Undo with `restore_issue_label`.

Restore a retired Linear issue label, making it available for use on issues again. Restoring a label group also restores every child label, including any that were retired separately.

List projects in the user's Linear workspace

Retrieve details of a specific project in Linear

Create or update a Linear project. If `id` is provided, updates the existing project; otherwise creates a new one. When creating, `name` and at least one team (via `addTeams` or `setTeams`) are required. Pass `template` to create the project from a project template. To change parts of the description without resending all of it, pass `patch` instead of `description`. `state` resolves against the project statuses of the lead team, so pass `leadTeam` when creating a multi-team project whose teams use different statuses.

List available project labels in a Linear workspace or team. Returns workspace labels by default; pass `team` to also include that team's labels. A team-scoped label carries a `team` field; different teams can hold same-named labels, so check it before acting on an ID. A retired label carries `retiredAt` and cannot be applied to new projects.

Retire a Linear project label so it cannot be applied to new projects. The label stays visible on projects that already have it. Retiring a label group also retires its child labels. Undo with `restore_project_label`.

Restore a retired Linear project label, making it available for use on projects again. Restoring a label group also restores every child label, including any that were retired separately.

Create or update a Linear project label. If `id` is provided, updates the existing label; otherwise creates a new one. When creating, `name` is required.

List release pipelines in the workspace.

List releases in the workspace, with optional filtering by pipeline, stage, version, and text.

Create, reply to, or edit a comment or persisted draft on a Linear diff. Set draft to true to save without submitting. Provide draftId to edit or submit a persisted draft, and commentId only to edit a submitted comment. Submitting an inline draft reuses its saved anchor; submitting a reply draft requires parentId again.

Resolve or reopen a top-level comment thread on a Linear diff

Delete a comment or persisted draft from a Linear diff

Approve a Linear diff, request changes, or submit a review comment

Update a Linear diff's title, description, reviewer requests, issue links, or status. Provide at least one update. Combined updates can partially succeed; inspect the result before retrying. Use merge_diff to merge and submit_diff_review to approve or request changes.

List the Linear issue, project, and document templates available to the authenticated user. Use this to find the template a team expects, then call get_template for its content.

Retrieve a Linear template by ID or name: the content it pre-fills, the ids it applies, its sub-issues, and its form fields. Pass the template to save_issue or save_project to apply it. References come back as ids, so read a name with the matching tool when you need one. A form template collects its answers through a form, so applying one here creates an issue with the form unanswered.
