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 138 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.

Linear MCP Server FAQ

Does StackOne have a Linear MCP server?
Yes. StackOne offers a hosted Linear MCP server with 138 pre-built actions, and every action is tested and QA'd by StackOne. Connect it to Claude, Cursor, and any other MCP client, or to any agent framework through the AI Action SDK. It ships with managed agent authentication, prompt injection defense, and tool discovery with server-side execution that preserve your agent's context window and keep reasoning performance.
Linear MCP server vs direct API integration — what's the difference?
A Linear MCP server and direct API integration serve different use cases. Direct API integration is for software-to-software — backend code calling Linear. A Linear MCP server is for AI agents — MCP clients like Claude and Cursor, plus framework agents built with OpenAI, LangChain, or Vercel AI — discovering and calling Linear at runtime. StackOne provides both.
How does Linear authentication work for AI agents?
Linear authentication for AI agents works through a StackOne Connect Session. Create one via the dashboard or the SDK — you get an auth link and ready-to-paste config for Claude Desktop, Cursor, and other MCP clients. Your user authenticates their own Linear account; StackOne handles token exchange, storage, and refresh. Credentials never reach the LLM, and each user is isolated via origin_owner_id.
Are Linear MCP tools vulnerable to prompt injection?
Yes — Linear MCP tools can be vulnerable to indirect prompt injection. Any tool that reads user-written content — documents, messages, tickets, records, or free-text fields — is a potential vector. StackOne Defender scans every tool response before it enters the agent's context — regex patterns in ~1ms, then a MiniLM classifier in ~4ms. 88.7% accuracy, CPU-only.
What is the context bloat of a Linear agent and how do I avoid it?
Context bloat happens when Linear tool schemas and API responses eat your Linear agent's memory, preventing it from reasoning effectively. A single Linear query can return a massive JSON response, and connecting multiple tools compounds the problem. Tools Discovery and Code Mode reduce context bloat — loading only relevant tools per query and keeping raw responses out of the agent's context.
Can I limit which actions my Linear agent can access?
Yes — you can limit which actions your Linear agent can access directly from the StackOne dashboard. Toggle actions on or off, or restrict them to specific accounts, with no code changes to your agent. Session tokens can be scoped to exact actions so if one leaks, exposure stays contained.
Can I create custom agent actions for my Linear MCP server?
Yes — you can create custom agent actions for your Linear MCP server using Connector Builder. It's an integration agent your coding assistant (Claude Code, Cursor, or Copilot) can invoke to research Linear's API, generate production-ready connector YAML, test against the live API, and validate before you ship.
When should I NOT use a Linear MCP server?
Skip a Linear MCP server if your integration is purely software-to-software — direct Linear API integration is simpler when no AI agent is involved. For deterministic, compliance-critical operations (financial transactions, regulatory reporting), direct API gives you predictable behavior without agent-driven decision-making. MCP shines when AI agents need to dynamically discover and call Linear actions at runtime.
What AI frameworks and AI clients does the StackOne Linear MCP server support?
The StackOne Linear MCP server supports both. MCP clients (paste-and-go apps): Claude Desktop, Claude Code, Cursor, VS Code, Goose. Agent frameworks (code SDKs you build with): OpenAI Agents SDK, Anthropic, Vercel AI, Google ADK, CrewAI, Pydantic AI, LangChain, LangGraph, Azure AI Foundry.
