Linear: MCP server, CLI and agent surfaces

Sign-in required, tools not seen, not counted. The MCP endpoint listed for Linear at mcp.linear.app answered 401 with OAuth metadata on 4 November 2026. Its tools can be listed only after a person authorizes a client, and this directory never signs in.

Fact sheet

Domain	linear.app
Category	Productivity (Ora leaderboard category)
MCP server	Sign-in required (OAuth with client registration)
Tranco rank	8,389 on the list of 4 November 2026
Ora score	69, grade C; Ora scanned the domain on 5 November 2026 and the cached score was read on 5 November 2026 from its score API (Ora's score page for linear.app, a vendor-published score)
Company found through	the vendor's own documentation; the awesome-remote-mcp-servers list; the official MCP Registry; Ora's public leaderboard

MCP server

Endpoint	`https://mcp.linear.app/mcp`
How it was found	listed in the vendor's own documentation; the awesome-remote-mcp-servers list; the official MCP Registry; Ora's public leaderboard
Transport	streamable-http
HTTP status	401
Connected	4 November 2026, 20:01 UTC
Handshake time	110 ms over 1 attempt
Documentation	linear.app

The endpoint answered the handshake with a sign-in challenge, so the tool list is not visible to this directory. It is not counted as an MCP server: a sign-in challenge is its own state, and the connector listed no tools.

Authentication

Auth type	OAuth with client registration
What the challenge said	`Bearer realm="OAuth", resource_metadata="https://mcp.linear.app/.well-known/oauth-protected-resource/mcp", scope="read write"`
Protected resource metadata	mcp.linear.app
Authorization server metadata	mcp.linear.app
Registration endpoint	`https://mcp.linear.app/register`
Client ID metadata documents	supported
Auth as listed by a registry	OAuth2.1 (a claim, not checked by connecting)

The sign-in route, step by step

Request https://mcp.linear.app/mcp without a token. It answers 401 and a WWW-Authenticate header.
Read the protected resource metadata at https://mcp.linear.app/.well-known/oauth-protected-resource/mcp to find the authorization server.
Register a client at the registration endpoint https://mcp.linear.app/register (dynamic client registration), so no human has to create an app first.
Send a person through the authorization page, then retry the endpoint with the bearer token. The connector stops after step 2 and never authorizes.

See OAuth for MCP: client ID metadata documents and dynamic registration for how each route works.

CLI

No CLI is on record for Linear. The directory checks a package only where a source names one, so this is a floor: a company can ship a command line that no source read for this edition mentions. See shipping a CLI agents can use.
