rollbar-mcp-server

rollbar-mcp-server

A Model Context Protocl (MCP) server for Rollbar.

[!NOTE] This software is pre-release, alpha quality, and under active development.

Features

This MCP server implementes the stdio server type, which means your AI tool (e.g. Claude) will run it directly; you don't run a separate process.

Configuration

ROLLBAR_ACCESS_TOKEN: a read-scope access token for your Rollbar project.

Tools

get-item-details(counter): Given an item number, fetch the item details and last occurrence details. Example prompt: Diagnose the root cause of Rollbar item #123456

get-deployments(limit): List deploy data for the given project. Example prompt: List the last 5 deployments or Are there any failed deployments?

get-version(version, environment): Fetch version details for the given version string, environment name, and the configured project.

get-top-items(environment): Fetch the top items in the last 24 hours given the environment name, and the configured project.

How to Use

Tested with node 22 (nvm use 22).

You can test an individual tool using the @modelcontextprotocol/inspector module. For example, test the tool get-item-details with arg counter=2455389:

npx @modelcontextprotocol/inspector --cli -e ROLLBAR_ACCESS_TOKEN=$TOKEN node build/index.js --method tools/call --tool-name get-item-details --tool-arg counter=2455389 --debug
