Sentry MCP server

This TypeScript implementation of the Model Context Protocol (MCP) server connects to the Sentry error tracking service, enabling AI models to retrieve and analyze error reports and events from Sentry. It provides tools to query issue details including stack traces, status, and timestamps.

Installation

To get started with the MCP Server Sentry:

# Install dependencies
npm install

# Build the project
npm run build

Configuration

The server requires configuration through environment variables. Create a .env file in the project root with the following settings:

# Required: Sentry authentication token
SENTRY_AUTH_TOKEN=your_sentry_auth_token

# Optional: Sentry organization name
SENTRY_ORGANIZATION_SLUG=your_organization_slug

# Optional: Sentry project name
SENTRY_PROJECT_SLUG=your_project_slug

# Optional: Sentry base url
SENTRY_BASE_URL=https://sentry.com/api/0

Environment Variables

• SENTRY_AUTH_TOKEN (required): Your Sentry API access token
• SENTRY_ORGANIZATION_SLUG (optional): The slug of your Sentry organization
• SENTRY_PROJECT_SLUG (optional): The slug of your Sentry project

Note: The organization and project slugs can be omitted if this information is provided in the issue URL.

Running the Server

Run the server via standard IO:

node dist/index.js

For debugging purposes, you can use the MCP Inspector:

npx @modelcontextprotocol/inspector node dist/index.js

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 "sentry" '{"command":"node","args":["dist/index.js"],"env":{"SENTRY_AUTH_TOKEN":"your_sentry_auth_token","SENTRY_ORGANIZATION_SLUG":"your_organization_slug","SENTRY_PROJECT_SLUG":"your_project_slug","SENTRY_BASE_URL":"https://sentry.com/api/0"}}'

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": {
        "sentry": {
            "command": "node",
            "args": [
                "dist/index.js"
            ],
            "env": {
                "SENTRY_AUTH_TOKEN": "your_sentry_auth_token",
                "SENTRY_ORGANIZATION_SLUG": "your_organization_slug",
                "SENTRY_PROJECT_SLUG": "your_project_slug",
                "SENTRY_BASE_URL": "https://sentry.com/api/0"
            }
        }
    }
}

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": {
        "sentry": {
            "command": "node",
            "args": [
                "dist/index.js"
            ],
            "env": {
                "SENTRY_AUTH_TOKEN": "your_sentry_auth_token",
                "SENTRY_ORGANIZATION_SLUG": "your_organization_slug",
                "SENTRY_PROJECT_SLUG": "your_project_slug",
                "SENTRY_BASE_URL": "https://sentry.com/api/0"
            }
        }
    }
}
