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.

Uncheck an MCP to remove it. Comparing two or three keeps each signal in its own row.

Side-by-side MCP evidence comparison
Evidence fieldRailwayWatchlist candidatebuildkiteMCP100 Selected
Task fit
Best for
  • Railway users who want project, environment and deployment workflows through an OAuth-scoped hosted MCP service.
  • CI/CD investigation and controlled Buildkite operations through hosted or self-managed MCP transports.
Not ideal for
  • Users who need a read-only server or who expect hosted and local Railway MCP modes to have identical tools.
  • Teams outside the publisher ecosystem or without least-privilege credentials
Avoid when
  • Avoid broad workspace/project authorization or destructive deployment operations when a narrower OAuth scope is sufficient.
  • The connected identity is broader than the task requires
  • Tool calls cannot be reviewed before consequential mutations

Access and data
AuthenticationHosted server uses Railway OAuth and can scope authorized workspaces/projects; local mode reuses Railway CLI login.Hosted access uses short-lived OAuth, while headless and local deployments use scoped Buildkite API tokens.
CostRailway resource/deployment usage and account-plan charges apply.The MCP integration has no separately verified MCP100 price conclusion. Publisher subscriptions, API usage, compute, storage, and AI-client charges may apply.
PermissionsCan mutate projects/deployments/services according to the authorized Railway user/scope. Hosted and local modes expose different tool surfaces.OAuth and API-token scopes govern organization, pipeline, build, job, artifact, and Test Engine access; a read-only hosted endpoint is available.
Data handlingProject metadata, variables requested by tools and deployment context can be shared with the AI client/provider.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
  • Promoted after strict re-audit: canonical identity and MCP-native/publisher-backed implementation are sufficiently evidenced, with real workflow value, usable documentation, understandable permissions, plausible maintenance, and no unresolved security veto. Still not strong enough for Selected.
  • Write-capable endpoints can rerun, cancel, or otherwise change CI state; use the read-only endpoint for investigation.
Risk contextDeployment mutation and potentially sensitive environment/project information require scope control and confirmation.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.
