Field-by-field comparison

Compare the evidence before choosing an MCP.

Each signal stays separate, missing facts remain visible, and the column order follows your selection.

Task fit
Best for
  • Debugging Cypress Cloud runs, failed tests, flaky tests, UI Coverage, and accessibility results without leaving the coding client
  • Teams that want a first-party hosted MCP with user-scoped access and revocable authentication
  • Human-in-the-loop issue, event, trace, and performance investigation
  • Coding agents working on one constrained Sentry project
  • Teams using the supported hosted OAuth service
Not ideal for
  • Teams that do not use Cypress Cloud
  • Workflows that need to modify tests, delete runs, or control CI through the MCP itself
  • General-purpose Sentry administration
  • Unattended remediation against production
  • Self-hosted users unwilling to configure tokens and optional LLM providers
Avoid when
  • Your organization cannot allow an AI client to read Cypress Cloud test data
  • You cannot use OAuth or safely manage a dedicated Cypress MCP personal access token
  • Error payloads may contain secrets or personal data that cannot be shown to the model/client
  • You cannot constrain the session to the intended organization/project
  • The requested OAuth scopes or write-capable skills exceed policy

Access and data
AuthenticationOAuth is recommended. Supported clients use browser sign-in and an automatically managed 30-day session. A Cypress MCP personal access token is available for clients that cannot use OAuth.The hosted service uses MCP OAuth layered over Sentry OAuth; raw Sentry credentials stay server-side. Stdio uses a Sentry user auth token and may also require OpenAI or Anthropic credentials for AI-powered search.
CostCloud MCP is included at no additional cost on all Cypress Cloud plans, including Starter. Current usage limit is 100 tool requests per hour; underlying Cypress Cloud plan/product availability and data retention still apply.The repository is source-available under its published license and the hosted MCP has no separately documented fee in the reviewed sources. Normal Sentry plan/usage, Seer, and external LLM-provider charges may apply.
PermissionsAccess is scoped to the authenticated Cypress Cloud user's existing roles and permissions in MCP-enabled organizations. Organization admins can disable the integration for the whole organization. OAuth sessions can be individually revoked.Hosted OAuth requests org:read, project:write, team:write, and event:write upstream, then narrows exposed actions through granted MCP skills and optional /mcp/:org/:project resource paths. Stdio documentation lists org/project/team read/write and event write token scopes.
Data handlingThe MCP returns Cypress Cloud test/run data such as run summaries, failed-test details, stack traces, Test Replay links, flake data, accessibility reports, and UI Coverage data. Cypress states that it receives tool-call inputs, not the user's AI conversation, and that returned Cypress data is not used to train or improve an LLM.Issue, event, trace, release, team, project, and related telemetry may be returned to the MCP client. Hosted mode stores upstream OAuth credentials in encrypted grant properties and gives the client a separate MCP token. AI search tools may process query/event context through configured model infrastructure.
Limitations
Tradeoffs
  • The server is deliberately read-oriented, which lowers blast radius but also means fixes still happen in your local code or other tools
  • Some tools depend on paid Cypress Cloud products or plan-specific data, and usage is rate-limited
  • The hosted server keeps upstream Sentry credentials server-side and narrows sessions by skills and paths, but requests broad upstream scopes.
  • AI-powered natural-language search may invoke an embedded model/provider; stdio self-hosting requires separate provider keys for those tools.
  • Self-hosted Sentry may lack features such as Seer and needs explicit skill disabling.
Risk contextLow to medium. The production data tools are read-oriented and user-scoped, but they can expose sensitive test/CI information to the connected AI client. The feedback tool sends feedback to Cypress, so the surface is not literally side-effect-free even though it cannot modify test code or delete runs.Production error telemetry often contains sensitive values, while upstream OAuth scopes include write capabilities. Prefer a project-constrained hosted URL, minimal granted skills, human approval for mutations, and prior telemetry scrubbing.
