Rollbar MCP server

The Rollbar MCP server provides integration with Rollbar's error tracking platform, allowing Large Language Models (LLMs) to access and analyze error data, deployment information, and user details from your Rollbar projects.

Installation

Using NPX (Recommended)

The easiest way to use the Rollbar MCP server is with NPX. Add the following configuration to your ~/.cursor/mcp.json:

{
    "mcpServers": {
      "rollbar-mcp": {
        "command": "npx",
        "args": ["-y", "@hiyorineko/mcp-rollbar-server"],
        "env": {
          "ROLLBAR_PROJECT_TOKEN": "YOUR_PROJECT_ACCESS_TOKEN",
          "ROLLBAR_ACCOUNT_TOKEN": "YOUR_ACCOUNT_ACCESS_TOKEN",
          "ROLLBAR_PROJECT_ID": "YOUR_PROJECT_ID",
          "ROLLBAR_PROJECT_NAME": "YOUR_PROJECT_NAME"
        }
      }
    }
}

Local Installation

Alternatively, you can install and run the server locally:

$ cd mcp-rollbar-server
$ npm install
$ npm run build

Then, update your ~/.cursor/mcp.json:

{
    "mcpServers": {
      "rollbar-mcp": {
        "command": "YOUR_NODE_PATH",
        "args": ["YOUR_PROJECT_PATH/mcp-rollbar-server/dist/src/index.js"],
        "env": {
          "ROLLBAR_PROJECT_TOKEN": "YOUR_PROJECT_ACCESS_TOKEN",
          "ROLLBAR_ACCOUNT_TOKEN": "YOUR_ACCOUNT_ACCESS_TOKEN",
          "ROLLBAR_PROJECT_ID": "YOUR_PROJECT_ID",
          "ROLLBAR_PROJECT_NAME": "YOUR_PROJECT_NAME"
        }
      }
    }
}

To find your Node.js path, run which node in your terminal.

Configuration

Required Environment Variables

Two types of tokens are used for different APIs:

• ROLLBAR_PROJECT_TOKEN: Required for project-level operations (errors, occurrences, environments, deployments)
• ROLLBAR_ACCOUNT_TOKEN: Required for account-level operations (projects, users)

Optional variables:

• ROLLBAR_PROJECT_ID: Default project ID when not specified in requests
• ROLLBAR_PROJECT_NAME: Default project name for reference

While you can use the server with only one token type, configuring both provides full functionality.

Obtaining Rollbar Tokens

1. Log in to your Rollbar account at https://rollbar.com/
2. For project tokens: Navigate to Settings → Project Access Tokens
3. For account tokens: Navigate to Settings → Account Access Tokens
4. Create new tokens with "read" scope

Usage Examples

The Rollbar MCP server provides multiple tools for interacting with Rollbar data. Here are some common usage patterns:

Listing Recent Errors

To retrieve the most recent errors in your production environment:

List the most recent errors in my production environment.

This will use the rollbar_list_items tool with the environment parameter set to "production".

Viewing Error Details

To get detailed information about a specific error:

Get detailed information for error item with ID 12345, including stack trace and recent occurrences.

This combines the rollbar_get_item and rollbar_list_occurrences tools.

Tracking Deployments

To view recent deployments:

Show me the recent deployments for project 67890.

This uses the rollbar_list_deploys tool with the specified project ID.

Filtering Errors by Severity

To find critical errors from the past week:

List all critical errors that occurred in the last week.

This uses the rollbar_list_items tool with level="critical" and appropriate time filters.

Available Tools

Error Management

• rollbar_list_items: Lists errors with optional filters for status, level, environment
• rollbar_get_item: Gets detailed information about a specific error by ID
• rollbar_get_item_by_counter: Retrieves an error using its project counter (visible ID in UI)
• rollbar_list_occurrences: Lists occurrences of errors with optional item ID filter
• rollbar_get_occurrence: Gets detailed information about a specific error occurrence

Project Management

• rollbar_list_projects: Lists all available projects
• rollbar_get_project: Gets detailed information about a specific project
• rollbar_list_environments: Lists environments for a specific project

User Management

• rollbar_list_users: Lists all users in the Rollbar account
• rollbar_get_user: Gets detailed information about a specific user

Deployment Tracking

• rollbar_list_deploys: Lists deployments with optional project and environment filters
• rollbar_get_deploy: Gets detailed information about a specific deployment

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.
