linear

A local emulator of Linear, a project-management service for tracking issues, teams, comments, projects, and workflows. It exposes a GraphQL API and OAuth endpoints for testing.

In plain words
What is it for?
Testing issue and comment operations, teams, workflow states, labels, projects, cycles, OAuth apps, webhooks, tokens, and basic agent sessions locally.
Why use it?
It lets developers test Linear integrations without sending requests to the real Linear service.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

linear scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Linear API Emulator

Stateful Linear GraphQL API emulation with organizations, users, teams, workflow states, issues, comments, labels, projects, cycles, OAuth apps, tokens, webhooks, and basic agent sessions.

Start

# Linear only
npx emulate --service linear

Default URL: http://localhost:4012 when all services are started, or http://localhost:4000 when Linear is the only service.

URL Mapping

Real Linear URL Emulator URL
https://api.linear.app/graphql $LINEAR_EMULATOR_URL/graphql
https://linear.app/oauth/authorize $LINEAR_EMULATOR_URL/oauth/authorize
https://api.linear.app/oauth/token $LINEAR_EMULATOR_URL/oauth/token
https://api.linear.app/oauth/revoke $LINEAR_EMULATOR_URL/oauth/revoke

Auth

GraphQL accepts a bearer token or bare personal API key:

curl "$LINEAR_EMULATOR_URL/graphql" \
  -H "Authorization: Bearer lin_test_admin" \
  -H "Content-Type: application/json" \
  -d '{"query":"{ viewer { id email } }"}'

Scope checks are relaxed by default. Set linear.strict_scopes: true in seed config to require supported operation scopes such as read, write, issues:create, comments:create, and admin.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
