Coverage
136 Agent Actions
Create, read, update, and delete across Linear — and extend your agent's capabilities with custom actions.
Authentication
Agent Tool Authentication
Per-user OAuth in one call. Your Linear MCP server gets session-scoped tokens with zero credentials stored on your infra.
Agent Auth →Security
Agent Protection
Every Linear tool response scanned for prompt injection in milliseconds — 88.7% accuracy, all running on CPU.
Prompt Injection Defense →Performance
Max Agent Context. Min Cost.
Free up to 96% of your agent's context window to enhance reasoning and reduce cost, on every Linear call.
Tools Discovery →What is the Linear MCP Server?
A Linear MCP server lets AI agents read and write Linear data through the Model Context Protocol — Anthropic's open standard for connecting LLMs to external tools. StackOne's Linear MCP server ships with 136 pre-built actions, fully extensible via the Connector Builder — plus managed authentication, prompt injection defense, observability, and agent execution runtime. Connect it from MCP clients like Claude Desktop, Claude Code, Cursor, Goose, and VS Code, or from agent frameworks like OpenAI Agents SDK, LangChain, and Vercel AI SDK.
All Linear MCP Tools
Every action from Linear's API, ready for your agent. Create, read, update, and delete — scoped to exactly what you need.
