Sentry MCP server

This MCP server implementation allows AI agents to access and analyze Sentry error data through a standardized interface. It provides tools for retrieving, analyzing and viewing detailed error information from Sentry.

Installation

To install the Sentry MCP server:

pnpm install

Configuration

Create a .env file in the root directory with your Sentry authentication settings:

SENTRY_AUTH_TOKEN=your_sentry_auth_token
SENTRY_API_BASE=https://sentry.io/api/0/  # Optional, defaults to this value

Starting the Server

Build and start the server with:

pnpm build && pnpm start

The server will run on port 1337 by default.

Using the MCP Interfaces

The server provides two different MCP interfaces:

Tool Interface

Use the get_sentry_issue tool by providing:

{
  "issue_id_or_url": "12345"
}

Prompt Interface

Use the sentry-issue prompt interface:

{
  "issue_id_or_url": "https://sentry.io/organizations/your-org/issues/12345/"
}

Cursor IDE Integration

The Sentry MCP Server works with Cursor IDE:

1. Start the MCP server locally using pnpm start
2. Configure Cursor to use your local MCP server
3. Analyze Sentry issues directly within your IDE environment

How to add this MCP server to 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 > MCP and click "Add new global MCP server".

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

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

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 explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
