get-top-items and list-items cut a noisy project down to the few worth looking at, then list-occurrences hands over the actual instances — stack traces, request data, environments — for the agent to reason over rather than a summary. update-item closes the loop, so the conversation that diagnosed the error is also where it gets marked resolved or handed to whoever owns that code.
Rollbar's own stdio server, launched by your client through npx. It reads a project's items, occurrences, deployments and session replays over the Rollbar API, and can write an item's status back.
- The items with the most occurrences in the last 24 hours for an environment, so triage starts with the worst one
- An item's full detail together with its most recent occurrence, from the counter shown in the Rollbar UI
- The individual occurrences behind an item, each with its own timestamp, environment and error detail
- Item search and filtering by status, level, environment or free text, with resolved and muted items out of the way by default
- Recent deployments, to line a release up against when errors started or stopped
- How one version — a git SHA — has behaved in an environment, including when it first and last appeared
- A session replay for a session, written to a temp file or returned as a rollbar:// link
- Status, level, title, assignee, resolved version, snooze state and owning team, changed from the conversation
- The list of Rollbar projects this server can reach, to pass into the other tools
A Rollbar token. ROLLBAR_ACCOUNT_ACCESS_TOKEN reaches every project on the account; ROLLBAR_ACCESS_TOKEN covers a single project. For several projects with different tokens, point ROLLBAR_CONFIG_FILE at a .rollbar-mcp.json listing them, or drop that file in the working directory or your home directory. Read scope covers every tool except update-item, which needs read and write. Runs over stdio through npx — no separate process to keep alive. ROLLBAR_API_BASE overrides the default https://api.rollbar.com/api/1.
One command plus a key — npx -y @rollbar/mcp-server@latest, then supply credentials
