Backlog MCP server

The Backlog MCP Server is an implementation that integrates with the Backlog API, allowing you to interact with Backlog projects, issues, and wikis through the Model Context Protocol (MCP). It provides a structured way to perform operations like retrieving, adding, updating, and deleting various Backlog resources.

Installation and Setup

Prerequisites

Before using the Backlog MCP Server, you need:

1. A Backlog account (sign up at Backlog)
2. A Backlog plan (free plan available here)
3. An API key generated from your Backlog account settings

Obtaining Your API Key

To generate an API key:

1. Log in to your Backlog account
2. Navigate to your individual settings
3. Generate an API key following Backlog's documentation

Required Environment Variables

The server requires the following environment variables:

• Required:
  • BACKLOG_API_KEY: Your Backlog API key
  • BACKLOG_SPACE_ID: Your Backlog space ID
• Optional:
  • BACKLOG_BASE_URL: Your Backlog base URL (default: https://{your-space-id}.backlog.com/api/v2)

Usage with Claude Desktop

Setup with NPX

Add the following configuration to your claude_desktop_config.json:

{
  "mcpServers": {
    "backlog": {
      "command": "npx",
      "args": [
        "-y",
        "backlog-mcp-server"
      ],
      "env": {
        "BACKLOG_API_KEY": "YOUR_API_KEY_HERE",
        "BACKLOG_SPACE_ID": "YOUR_SPACE_ID_HERE"
      }
    }
  }
}

Setup with Docker

Alternatively, you can use Docker:

{
  "mcpServers": {
    "backlog": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e",
        "BACKLOG_API_KEY=YOUR_API_KEY_HERE",
        "-e",
        "BACKLOG_SPACE_ID=YOUR_SPACE_ID_HERE",
        "mcp/backlog"
      ],
      "env": {
        "BACKLOG_API_KEY": "YOUR_API_KEY_HERE",
        "BACKLOG_SPACE_ID": "YOUR_SPACE_ID_HERE"
      }
    }
  }
}

Available Tools

Project Management

• backlog_get_projects: Retrieve projects with pagination and filtering
• backlog_get_project: Get a specific project by ID or key

Issue Management

• backlog_get_issues: Retrieve issues with pagination and filtering
• backlog_get_issue: Get a specific issue by ID or key
• backlog_add_issue: Create a new issue with provided data
• backlog_update_issue: Update an existing issue

Each tool follows the MCP protocol for interaction with the Backlog API, providing a consistent interface for managing your Backlog resources.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "backlog" '{"command":"npx","args":["-y","backlog-mcp-server"],"env":{"BACKLOG_API_KEY":"YOUR_API_KEY_HERE","BACKLOG_SPACE_ID":"YOUR_SPACE_ID_HERE"}}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "backlog": {
            "command": "npx",
            "args": [
                "-y",
                "backlog-mcp-server"
            ],
            "env": {
                "BACKLOG_API_KEY": "YOUR_API_KEY_HERE",
                "BACKLOG_SPACE_ID": "YOUR_SPACE_ID_HERE"
            }
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "backlog": {
            "command": "npx",
            "args": [
                "-y",
                "backlog-mcp-server"
            ],
            "env": {
                "BACKLOG_API_KEY": "YOUR_API_KEY_HERE",
                "BACKLOG_SPACE_ID": "YOUR_SPACE_ID_HERE"
            }
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
