Maintenance

Recheck needed

The source snapshot needs another refresh before maintenance can be interpreted.

Popularity

Signals unavailable

No independently comparable adoption metric is currently stored.

Best for

Railway users who want project, environment and deployment workflows through an OAuth-scoped hosted MCP service.

Not ideal for

Users who need a read-only server or who expect hosted and local Railway MCP modes to have identical tools.

Avoid if

Avoid broad workspace/project authorization or destructive deployment operations when a narrower OAuth scope is sufficient.

Trade-offs

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.

Evidence-backed setup

Install & Agents

Choose your MCP client. A client connects to the MCP server; the language model is selected inside that client. Only stored, source-backed configurations are shown.

Claude Code

Transport not recorded

Publisher documented

Authenticate with current Railway CLI (`railway login`), then use `railway mcp` / `railway mcp install --agent claude-code`; hosted clients can connect to `https://mcp.railway.com` and use OAuth.

The publisher provides client-specific setup instructions.

Verify safely: Claude Code: `claude mcp list` and/or `/mcp` to confirm Connected; use any stronger vendor-documented smoke test where listed.

Uninstall and revoke

Claude Code: `claude mcp remove <name>`; also revoke OAuth/device/API credentials in the vendor account when the vendor provides such a control.

Evidence & methodology

Publisher-documented setup is not the same as MCP100 execution testing. “MCP100 logic checked” means the stored configuration shape was reviewed, not that third-party MCP software was run.

Reviewed access

Access & risk

Review the exact access boundary before connecting this MCP to accounts, credentials, or sensitive data.

Authentication: Hosted server uses Railway OAuth and can scope authorized workspaces/projects; local mode reuses Railway CLI login.
Permissions: Can mutate projects/deployments/services according to the authorized Railway user/scope. Hosted and local modes expose different tool surfaces.
Data handling: Project metadata, variables requested by tools and deployment context can be shared with the AI client/provider.
Cost: Railway resource/deployment usage and account-plan charges apply.
Risk and cautions: Deployment mutation and potentially sensitive environment/project information require scope control and confirmation.
