Unlock 5x Developer Velocity: Build a Linear MCP Server For Autonomous Triage (2026)

By Deepak Bagada, CEO at SaaSNext & Principal AI Architect

In modern engineering teams, tracking issues and maintaining project hygiene often becomes a massive time sink. With the Model Context Protocol (MCP), we can offload this cognitive burden to AI agents. By building a Linear MCP Server, we grant models like Claude the ability to query project states, update tickets, and triage incoming bugs entirely on their own.

This guide will walk you through building a production-ready Linear MCP Server in 2026.

The Age of Autonomous Project Management

Linear's GraphQL API is incredibly powerful, but interfacing with it via rigid scripts is limiting. MCP standardizes this interface. When an agent has access to a Linear MCP server, you can simply tell it: "Find all high-priority bugs from last week and assign them to the on-call engineer." The agent handles the tool calling natively.

In our production deployment at SaaSNext, we integrated a Linear MCP server into our internal Slackbot. The result? A 40% reduction in time spent organizing sprints, as the AI automatically linked GitHub PRs to Linear issues based on semantic context.

Quick Start: Server in 5 Minutes

1. Set up your TypeScript project:

mkdir linear-mcp && cd linear-mcp
npm init -y
npm install @modelcontextprotocol/sdk @linear/sdk zod dotenv
npm install -D typescript @types/node tsx
npx tsc --init

2. Obtain a Linear Personal Access Token from Linear Settings > API and save it in a .env file:

LINEAR_API_KEY=lin_api_...

Full TypeScript Code

Here is the complete implementation of the Linear MCP Server, leveraging the official @linear/sdk and zod for input validation.

import { Server } from '@modelcontextprotocol/sdk/server/index.js';
import { StdioServerTransport } from '@modelcontextprotocol/sdk/server/stdio.js';
import {
  CallToolRequestSchema,
  ErrorCode,
  ListToolsRequestSchema,
  McpError,
} from '@modelcontextprotocol/sdk/types.js';
import { LinearClient } from '@linear/sdk';
import { z } from 'zod';
import dotenv from 'dotenv';

dotenv.config();

const LINEAR_API_KEY = process.env.LINEAR_API_KEY;
if (!LINEAR_API_KEY) {
  console.error('Missing LINEAR_API_KEY environment variable');
  process.exit(1);
}

const linearClient = new LinearClient({ apiKey: LINEAR_API_KEY });

const server = new Server(
  {
    name: 'linear-mcp-server',
    version: '1.0.0',
  },
  {
    capabilities: {
      tools: {},
    },
  }
);

// Zod Schemas
const CreateIssueSchema = z.object({
  title: z.string(),
  description: z.string().optional(),
  teamId: z.string(),
  priority: z.number().min(0).max(4).optional(),
});

const UpdateIssueStatusSchema = z.object({
  issueId: z.string(),
  stateId: z.string(),
});

const SearchIssuesSchema = z.object({
  query: z.string(),
  limit: z.number().optional().default(10),
});

// Tool Registration
server.setRequestHandler(ListToolsRequestSchema, async () => {
  return {
    tools: [
      {
        name: 'create_issue',
        description: 'Create a new issue in Linear',
        inputSchema: {
          type: 'object',
          properties: {
            title: { type: 'string' },
            description: { type: 'string' },
            teamId: { type: 'string' },
            priority: { type: 'number', description: '0=No Priority, 1=Urgent, 2=High, 3=Medium, 4=Low' }
          },
          required: ['title', 'teamId']
        }
      },
      {
        name: 'update_issue_status',
        description: 'Update the state of an existing Linear issue',
        inputSchema: {
          type: 'object',
          properties: {
            issueId: { type: 'string' },
            stateId: { type: 'string' }
          },
          required: ['issueId', 'stateId']
        }
      },
      {
        name: 'search_issues',
        description: 'Search for issues across the Linear workspace',
        inputSchema: {
          type: 'object',
          properties: {
            query: { type: 'string' },
            limit: { type: 'number' }
          },
          required: ['query']
        }
      }
    ],
  };
});

// Tool Execution
server.setRequestHandler(CallToolRequestSchema, async (request) => {
  try {
    if (request.params.name === 'create_issue') {
      const args = CreateIssueSchema.parse(request.params.arguments);
      const response = await linearClient.createIssue({
        title: args.title,
        description: args.description,
        teamId: args.teamId,
        priority: args.priority
      });
      const issue = await response.issue;
      return { content: [{ type: 'text', text: JSON.stringify(issue, null, 2) }] };
    }

    if (request.params.name === 'update_issue_status') {
      const args = UpdateIssueStatusSchema.parse(request.params.arguments);
      const response = await linearClient.updateIssue(args.issueId, {
        stateId: args.stateId
      });
      const issue = await response.issue;
      return { content: [{ type: 'text', text: JSON.stringify(issue, null, 2) }] };
    }

    if (request.params.name === 'search_issues') {
      const args = SearchIssuesSchema.parse(request.params.arguments);
      const issues = await linearClient.issueSearch(args.query, { first: args.limit });
      return { content: [{ type: 'text', text: JSON.stringify(issues.nodes, null, 2) }] };
    }

    throw new McpError(ErrorCode.MethodNotFound, `Tool not found: ${request.params.name}`);
  } catch (error) {
    return {
      content: [{ type: 'text', text: `Error interacting with Linear: ${error}` }],
      isError: true,
    };
  }
});

async function main() {
  const transport = new StdioServerTransport();
  await server.connect(transport);
  console.error('Linear MCP server running on stdio');
}

main().catch(console.error);

OAuth 2.0 Security Guide

While Personal Access Tokens (PATs) are fine for local development or single-user instances, distributing this MCP server across your organization requires implementing Linear's OAuth 2.0 flow.

1. Register an OAuth App in Linear: Go to your workspace settings, create an application, and configure the redirect URI.
2. Authorization Code Flow: Direct the user to https://linear.app/oauth/authorize with your client_id, redirect_uri, and requested scope (e.g., read,write).
3. Token Management: Once the user authorizes, Linear sends a code to your server. Exchange this code at https://api.linear.app/oauth/token. Securely store the returned access token and pass it dynamically when initializing the MCP server for a specific user session.
