## Which one, for what

### Railway MCP Server (C)

Good for: Agents that deploy and operate applications on Railway from an editor and are content to hand multi-step work to Railway's own agent.

Ahead on:
- Security & auth, 65 against 58
- Maintenance & community, 83 against 56

Watch for: The hosted server's source and tool schemas are not public, so inputs can only be read after signing in.

### Render MCP Server (B)

Good for: Agents that deploy and debug applications on Render, reading logs and metrics and querying Postgres.

Ahead on:
- Schema & documentation, 76 against 56
- Agent ergonomics, 69 against 59
- Transparency & trust, 84 against 73

Also in its favour:
- Open source
- No incidents deducted, where Railway MCP Server loses 4 points for them

Watch for: No scopes and no read-only mode. An API key reaches every workspace its owner belongs to, and a read-only toolset request has been open since 8 October 2025.

## Verdicts

**Railway MCP Server.** A small hosted server with 11 tools, OAuth grants limited to chosen workspaces and one-hour tokens. Most infrastructure work goes through the `railway-agent` tool, which is billed by model tokens. The hosted server's source and tool schemas are not public, there is no read-only scope, and the status page lists about 25 incidents in 90 days.

**Render MCP Server.** A hosted server with 26 typed and annotated tools, OAuth or API key access and Apache-2.0 source. It cannot delete resources and wraps SQL in a read-only transaction. There are no scopes and no read-only mode, a key reaches every workspace its owner belongs to, and Render's status page recorded several major incidents in 90 days.

## Before you call either

### Railway MCP Server

1. Connect to `https://mcp.railway.com` with OAuth, or run `railway mcp` after `railway login`. Project tokens are refused.
2. Treat `redeploy`, `accept-deploy`, `delete-feature-flag` and `railway-agent` as actions that change production. Confirm the project and environment first.
3. `railway-agent` spends model tokens billed to the workspace. Use the single-purpose tools for listing and redeploying.
4. For variables, domains, volumes, logs or metrics as separate tools, use `railway mcp local`, which has a different tool set.
5. On a 401, follow the `WWW-Authenticate` challenge and run the OAuth flow again. Access tokens expire after one hour.

### Render MCP Server

1. Pass `workspaceId` on every resource tool call. Session-based workspace selection through `select_workspace` is deprecated and scheduled for removal.
2. Do not call `trigger_deploy` after pushing to a service with autoDeploy on. The push already starts a deploy.
3. Use an API key in the `Authorization` header for CI. OAuth grants expire and need a person to approve the browser flow again.
4. `update_environment_variables` merges by default. Set `replace` to true only to overwrite the whole set.
5. Expect 429 from the Render API at 20 service creations an hour and 10 deploys a minute per service. Back off with jitter.
