5 issues

Authentication & Identity

LOWImplements MCP OAuth spec for per-user authentication

Two transport modes: (1) Stdio with PAT via --access-token flag or SENTRY_ACCESS_TOKEN env var, with device code flow for interactive auth and token caching. (2) Cloudflare-hosted remote server with full MCP OAuth spec implementation including .well-known/oauth-authorization-server, .well-known/oauth-protected-resource, and StreamableHTTP transport. Region-aware API routing.

Remediation

Document the required OAuth scopes for each tool.

Tool Schema Quality

MEDIUMOnly 2 of 25 schemas have parameter constraints

Most schemas lack maxLength, enum, or pattern constraints on string parameters.

Remediation

Add constraints to string parameters, especially on write operations.

LLM Safety

HIGHTool descriptions contain instructional language

Descriptions include directives that could influence LLM behavior beyond tool selection.

Remediation

Remove instructional language. Descriptions should be purely factual.

Data Exposure

MEDIUM3 list operations lack pagination

find_organizations, find_teams, find_projects have internal result limits (e.g., 25). search_events and search_issues delegate to AI agents that build paginated Sentry API queries. list_issues/list_events have cursor-based pagination. No field selection. Token overhead is actively measured and managed.

Remediation

Add limit/offset or cursor-based pagination.

LOWNo field selection on responses

Responses return full records rather than projected fields.

Remediation

Implement field selection to return only relevant fields.
