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.

Evidence fieldStackQL MCPWatchlist candidatebuildkiteMCP100 Selected
Task fit
Best for
  • Read-only cloud inventory and governed infrastructure queries
  • Teams that can enforce read_only or safe mode with audit logging
  • CI/CD investigation and controlled Buildkite operations through hosted or self-managed MCP transports.
Not ideal for
  • Unattended infrastructure mutation without approval and audit
  • Organizations that cannot tightly scope cloud credentials by provider/account
  • Teams outside the publisher ecosystem or without least-privilege credentials
Avoid when
  • You would run full_access with broad cloud credentials
  • You cannot review audit logs or enforce tool allowlists
  • The connected identity is broader than the task requires
  • Tool calls cannot be reviewed before consequential mutations

Access and data
AuthenticationUses provider credentials supplied to StackQL; authentication varies by cloud provider. The MCP transport itself can be stdio/HTTP/TLS depending on deployment.Hosted access uses short-lived OAuth, while headless and local deployments use scoped Buildkite API tokens.
CostOpen-source; cloud provider usage and hosting costs apply.The MCP integration has no separately verified MCP100 price conclusion. Publisher subscriptions, API usage, compute, storage, and AI-client charges may apply.
PermissionsServer mode controls mutation: read_only refuses writes; safe/default requires approval; delete_safe and full_access expand privileges. enabled_tools can narrow exposure.OAuth and API-token scopes govern organization, pipeline, build, job, artifact, and Test Engine access; a read-only hosted endpoint is available.
Data handlingCan read cloud inventory/configuration and, when permitted, mutate or invoke provider lifecycle operations. Audit logs can record calls.Authorized service data and tool results pass through the MCP server to the connected AI client. Review the publisher and client data policies before using sensitive cloud & devops information.
Limitations
Tradeoffs
  • Default safe/read-only modes materially improve control
  • The same server can still become a powerful cloud control plane when escalated
  • Write-capable endpoints can rerun, cancel, or otherwise change CI state; use the read-only endpoint for investigation.
Risk contextHigh. In full or writable modes the server can change cloud infrastructure. Keep read_only/safe defaults, least-privileged provider credentials, and audit logging.Write-capable endpoints can rerun, cancel, or otherwise change CI state; use the read-only endpoint for investigation. Use a test environment where practical, least-privilege credentials, narrowly enabled tools, and explicit confirmation for mutations. MCP100 did not execute third-party server code during this documentation review.
