Linear MCP (Cloudflare Workers)

About Linear: • Linear is a purpose‑built tool for modern product development — issues, projects, roadmaps and cycles. What I built: • A typed MCP server exposing Linear tools behind a clean JSON‑RPC contract. • Runs on Cloudflare Workers for globally distributed, fast execution and simple secret management. • Small Hono router + GraphQL helpers; human‑friendly inputs are resolved to Linear IDs when needed. Capabilities (tools): • linearCreateIssue — create by team key; supports due dates. • linearUpdateIssue — update title/description/state (accepts state name/type alias), assignee, due date. • linearComment — add Markdown comments by id or key (e.g., ENG‑123). • linearDeleteIssue — remove issues by id or key. • linearListIssues — filter by team, assignee, state and date ranges (supports pagination). • linearListIssuesToday — issues updated today for a team or assignee. • linearGetIssue — detailed single issue (with relationships). • linearWebhookCreate / linearWebhookDelete — HMAC‑validated webhooks; optional signed forwarding. Why it matters: • Operate Linear from LLM clients with guardrails; automate triage, updates and project routines. • Secure by design — credentials in Workers Secrets; HMAC verification for webhooks.
