Sentry MCP vs Rollbar MCP Server

When to pick Sentry MCP

• You are fixing a bug already recorded in Sentry and need production evidence in the coding conversation. Use get_issue_details, get_event_stacktrace and get_trace_details to inspect the issue, stack trace and trace while working on the code.
• You want a hosted MCP connection. Sentry provides a remote service with OAuth-backed sessions, plus an explicit-token option for clients that support custom HTTP headers.
• Your team operates self-hosted Sentry. Run the server locally over stdio and select your deployment with --host. The documentation describes stdio support as work in progress; Seer is excluded from the default skills for non-Sentry hosts.
• You want the agent to investigate an issue and record the result in Sentry. The tool set includes analyze_issue_with_seer, update_issue and add_issue_note, within a workflow designed for coding agents supervised by a developer.

When to pick Rollbar MCP Server

• Your errors live in Rollbar and you need to decide what to investigate first. get-top-items identifies items with the most occurrences in an environment over the last 24 hours; list-items filters by status, level, environment or query text.
• You suspect a release caused a regression. Use get-deployments to inspect recent deployments and get-version to check when a version appeared in occurrences within an environment.
• You need individual error occurrences or the session replay leading up to an error. list-occurrences exposes occurrence details, while get-replay fetches replay metadata and payload using session and replay identifiers.
• You want account-wide reading with updates restricted to selected projects. In account mode, a read-scoped account token can coexist with explicitly configured project tokens that grant write access only where needed.

Main differences

• Sentry offers hosted remote access and a local stdio process. Rollbar uses stdio: the MCP client launches its npm package directly. Choose the connection model your workflow needs alongside the service holding your error data.
• Sentry's documented local setup uses a user auth token with organization, project, team and event scopes. Rollbar supports project, account and user tokens. Account or user tokens need both read and write scopes for update-item; project tokens need write scope.
• Sentry exposes issue, stack-trace, trace and Seer analysis tools. Rollbar exposes item, occurrence, deployment, version and replay tools. Its get-item-details response includes the latest occurrence, so an initial investigation can start with one lookup.
• Sentry's AI-powered search tools require a configured LLM provider; without one, those tools are unavailable while other tools continue working. Rollbar documents filtering through list-items parameters without an additional LLM-provider configuration step.
• Both support changes to tracked errors. Sentry lists issue updates and notes. Rollbar supports item updates and comments, but posting comments requires a user token with read and write scopes plus project comment permission; an account or project token cannot post them.

Setup

For Sentry, launch locally with npx @sentry/mcp-server@latest --access-token=sentry-user-token. Add --host=sentry.example.com for self-hosted Sentry. For AI-powered search, configure EMBEDDED_AGENT_PROVIDER and the chosen provider's credentials. Hosted access uses the endpoint https://mcp.sentry.dev/mcp.

For Rollbar, configure your MCP client to run npx -y @rollbar/mcp-server@latest over stdio. Set ROLLBAR_ACCESS_TOKEN for a project or ROLLBAR_ACCOUNT_ACCESS_TOKEN for account access. Use ROLLBAR_USER_ACCESS_TOKEN when posting comments; do not configure user and account tokens together. For a token configuration file, set ROLLBAR_CONFIG_FILE to its path.
