linear-mcp

Multi-workspace Linear MCP server with Personal API Key auth. Drop-in replacement for the official OAuth-only Linear MCP at mcp.linear.app/mcp.

Why this exists. The official Linear MCP is OAuth-only and single-workspace per instance. PAT auth plus persistent token storage plus multi-workspace routing kills three failure modes:

The OAuth flow is brittle across MCP client session boundaries — auth state expires when a session resumes mid-flow.
The localhost callback fails in some setups, forcing fragile paste-back flows.
One MCP instance per workspace doubles config + OAuth dances.

This server replaces both with one entry. One install, N workspaces, never an OAuth dance again.

Install

From PyPI

pipx install adelaidasofia-linear-mcp

From source

git clone https://github.com/adelaidasofia/linear-mcp ~/.claude/linear-mcp
cd ~/.claude/linear-mcp
pip install -e .

Claude Desktop one-click

Download the latest .mcpb from Releases and double-click.

Configure

Generate one Personal API Key per workspace at https://linear.app/settings/account/security. You must be logged into each workspace separately while generating the key for that workspace.
Create ~/.claude/linear-mcp/admin.env (chmod 600):

LINEAR_WORKSPACES=personal,work
LINEAR_PRIMARY_WORKSPACE=personal

LINEAR_PAT_PERSONAL=lin_api_xxxxxxxxxxxxxxxxxxxxxxxxxxxx
LINEAR_PAT_WORK=lin_api_xxxxxxxxxxxxxxxxxxxxxxxxxxxx

LINEAR_LABEL_PERSONAL=Personal
LINEAR_LABEL_WORK=Work

Aliases are arbitrary — name them whatever helps you route (acme,beta, team1,team2, home,client).

chmod 600 ~/.claude/linear-mcp/admin.env

claude mcp add -s user linear-mcp python3 -m linear_mcp.server

Or, with pipx install:

claude mcp add -s user linear-mcp linear-mcp

Restart Claude Code. healthcheck should return ok: true per workspace.

Substrate-layer enforcement (v0.3)

Three server-side checks that protect issue quality without depending on any markdown rule file or client-side memory. Apply only to WRITE paths; reads stay unconstrained.

Layer	What it does	Bypass env var
`[source:]` first-line check	`save_issue` / `save_project` reject CREATE calls whose `description` (or project `content`) does not start with `[source: <canonical-key>]`. UPDATE calls (`id` passed) skip the check so legacy backfills remain unblocked.	`LINEAR_MCP_SKIP_SOURCE_CHECK=1`
Idempotency check	Before any CREATE, the server runs `searchIssues` / `searchProjects` for `[source: <key>]` and refuses to create a duplicate. The error names the existing identifier + UUID so the caller can update in place.	`LINEAR_MCP_SKIP_IDEMPOTENCY=1`
`auth_phrase` on `bulk_save_issues`	`bulk_save_issues` now requires `auth_phrase` ∈ {`"go"`, `"yes do it"`, `"confirmed"`, `"execute"`, `"go cancel"`, `"go update"`} (case-insensitive). Mass-modification surface stays explicit.	(no bypass — surface the phrase to the operator)

Canonical-key examples:

Fast issue execution

linear-exec is the short path for starting real work from a Linear issue. It resolves the issue, checks blocking relations, scans same-project siblings for obvious scope overlap, infers the repo when possible, and can create the standard claude-dev-worktree branch.

Dry-run a specific issue:

linear-exec execute MYC-150 --workspace mycelium

Start the work after reviewing the preflight:

linear-exec execute MYC-150 --workspace mycelium --repo memory-runtime-pro --go

Find the next unblocked P1 issue in a workspace:

linear-exec sweep mycelium p1
linear-exec sweep mycelium p1 --go --repo memory-runtime-pro

The command refuses to proceed when an upstream blocks relation is still incomplete unless --force is passed. --no-state-update and --no-worktree let agents use only the parts of the preflight they need.

Tool surface (v0.3 — 57 tools + 3 prompts)

Every tool takes an optional workspace parameter (the alias from LINEAR_WORKSPACES). Omit it to use LINEAR_PRIMARY_WORKSPACE.

Tool	Purpose
`list_workspaces`	Show configured workspaces and primary
`healthcheck`	Verify each PAT + surface remaining rate-limit budget

Core entities

Tool	Purpose
`list_teams` / `get_team`	Teams (with inline workflow states)
`list_users` / `get_user`	Users (`me` resolves to PAT owner)
`list_projects` / `get_project` / `save_project`	Projects (v0.3: `save_project` enforces `[source:]` on `content` + idempotency on CREATE)
`list_initiatives` / `get_initiative` / `save_initiative`	Initiatives
`list_issues` / `get_issue` / `save_issue` / `bulk_save_issues`	Issues (id or `ONDE-123`; bulk uses `issueBatchUpdate`; v0.3: `save_issue` enforces `[source:]` + idempotency on CREATE; `bulk_save_issues` requires `auth_phrase`)
`list_cycles`	Cycles
`list_milestones` / `get_milestone` / `save_milestone`	Project milestones
`list_issue_statuses` / `get_issue_status`	Workflow states
`list_issue_labels` / `create_issue_label`	Labels
`list_comments` / `save_comment`	Comments
`list_documents` / `get_document` / `save_document`	Documents
`save_status_update`	Post a project status update

Webhooks (v0.2)

Tool	Purpose
`list_webhooks` / `get_webhook`	Inspect subscriptions
`create_webhook` / `update_webhook`	Manage subscriptions
`delete_webhook`	Destructive — draft+confirm

Notifications / inbox (v0.2)

Tool	Purpose
`list_notifications` / `get_notification`	Inbox read
`notifications_unread_count`	Top-of-mind counter
`mark_notification_read` / `mark_all_notifications_read`	Triage
`archive_notification`	Sweep

Attachments (v0.2)

Tool	Purpose
`list_attachments` / `get_attachment`	Per-issue reads
`attachments_for_url`	Reverse lookup: which issues link to this URL?
`link_url_to_issue`	Attach any URL to an issue
`delete_attachment`	Destructive — draft+confirm

Issue relations (v0.2)

Tool	Purpose
`list_issue_relations`	The blocks/duplicate/related graph
`create_issue_relation` / `delete_issue_relation`	Manage the graph

Agent sessions (v0.2)

Tool	Purpose
`list_agent_sessions` / `get_agent_session`	Linear's first-class agent surface
`create_agent_session_on_issue` / `create_agent_session_on_comment`	Spawn

Search (v0.2 — replaces v0.1's broken `search_documentation`)

Tool	Purpose
`search_issues` / `search_documents` / `search_projects`	Full-text per entity type
`semantic_search`	Workspace-wide semantic across all entities

MCP prompts (v0.2)

Available as slash commands in MCP clients that surface prompts:

/triage-issue — full triage pass: classify, label, prioritize, assign, link duplicates
/project-status — draft a weekly status update from current Linear state
/inbox-sweep — sweep today's notifications, propose actions, archive what's handled

Multi-workspace usage

Switch workspaces inline:

list_teams(workspace="work")
save_issue(workspace="personal", title="Ship", team_id="...")

Without workspace, the primary is used.

Auth

Linear PATs use header Authorization: <key> (no Bearer prefix). Each PAT is scoped to one workspace and grants access only to data the owning user can see. There is no shared org token.

Rate limit: 2500 requests/hour per token (verified against live API 2026-05-23). The server passes Linear's Retry-After header through on 429 and surfaces remaining budget via healthcheck.

Safety

Read tools and routine writes (create/update issues, comments, labels, status updates) pass through. Destructive ops (delete_webhook, delete_attachment) use the draft+confirm pattern: the first call stages the change and returns a draft_id + preview of what will happen; the second call (with confirm_draft_id) commits. Drafts expire after 1 hour (override with LINEAR_MCP_DRAFT_TTL_SECONDS).

Every tool call appends one JSONL line to ~/.claude/linear-mcp/audit.log (override with LINEAR_MCP_AUDIT_LOG_PATH, disable with LINEAR_MCP_AUDIT_LOG=false). Tokens are stripped from audit records.

healthcheck surfaces each PAT's remaining rate-limit budget (X-RateLimit-Requests-Remaining + X-Complexity-Remaining) per workspace, so agents can self-throttle without making a separate observability call.
