Render MCP Server

The Render MCP server lets AI coding tools manage Render services, databases, deploys, logs, and metrics directly. This skill covers setup, authentication, workspace selection, the tool catalog, and troubleshooting.

Action skills (render-deploy, render-debug, render-monitor) use MCP tools for their workflows. If MCP is not connected, set it up using this skill first.

When to Use

• list_services() fails or MCP tools are unavailable
• First-time Render MCP setup for any AI tool
• User asks how to connect their AI tool to Render
• Switching workspaces or troubleshooting auth errors
• Discovering which MCP tools exist and what they do

Connection Details

| Property | Value | |----------|-------| | URL | https://mcp.render.com/mcp | | Transport | HTTP (streamable) | | Auth | Bearer token (Render API key) | | API key page | https://dashboard.render.com/u/*/settings#api-keys | | Docs | https://render.com/docs/mcp-server |

Setup by Tool

Cursor

1. Get an API key from the Render Dashboard

2. Add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "render": {
      "url": "https://mcp.render.com/mcp",
      "headers": {
        "Authorization": "Bearer <YOUR_API_KEY>"
      }
    }
  }
}

3. Restart Cursor, then verify with list_services()

Claude Code

1. Get an API key from the Render Dashboard

2. Add the MCP server:

claude mcp add --transport http render https://mcp.render.com/mcp --header "Authorization: Bearer <YOUR_API_KEY>"

3. Restart Claude Code, then verify with list_services()

Codex

1. Get an API key from the Render Dashboard

2. Set the key in your shell:

export RENDER_API_KEY="<YOUR_API_KEY>"

3. Add the MCP server:

codex mcp add render --url https://mcp.render.com/mcp --bearer-token-env-var RENDER_API_KEY

4. Restart Codex, then verify with list_services()

Other Tools

For tools not listed above, use the generic HTTP MCP configuration:

• URL: https://mcp.render.com/mcp
• Auth header: Authorization: Bearer <YOUR_API_KEY>
• Transport: HTTP (streamable HTTP, not SSE)

See Render MCP docs for tool-specific instructions.

Workspace Selection

After MCP is connected, set the active workspace:

Set my Render workspace to [WORKSPACE_NAME]

Or programmatically:

get_selected_workspace()   # Check current
list_workspaces()          # List available

All MCP operations run against the active workspace.

Tool Catalog

Service management

| Tool | Purpose | |------|---------| | list_services() | List all services and datastores | | get_service(serviceId) | Get service details | | create_web_service(...) | Create a web service from Git repo | | create_static_site(...) | Create a static site from Git repo | | update_service(serviceId, ...) | Update service configuration | | restart_service(serviceId) | Restart a service |

Deploys

| Tool | Purpose | |------|---------| | list_deploys(serviceId, limit) | List deploys for a service | | trigger_deploy(serviceId) | Trigger a new deploy |

Logs

| Tool | Purpose | |------|---------| | list_logs(resource, level, type, text, statusCode, limit) | Query logs with filters |

Key filters: level (error, warn, info), type (build, deploy), text (search string), statusCode (HTTP codes).

Metrics

| Tool | Purpose | |------|---------| | get_metrics(resourceId, metricTypes, ...) | Get service or database metrics |

Metric types: cpu_usage, memory_usage, cpu_limit, memory_limit, http_latency, http_request_count, active_connections.

Optional: httpLatencyQuantile (0.5, 0.95, 0.99), httpPath (filter by endpoint).

Databases

| Tool | Purpose | |------|---------| | list_postgres_instances() | List Postgres databases | | get_postgres(postgresId) | Get database details | | query_render_postgres(postgresId, sql) | Run SQL query |

Key Value

| Tool | Purpose | |------|---------| | list_key_value() | List Key Value instances | | get_key_value(keyValueId) | Get Key Value details |

Environment Variables

| Tool | Purpose | |------|---------| | update_environment_variables(serviceId, envVars) | Set env vars on a service |

Workspace

| Tool | Purpose | |------|---------| | list_workspaces() | List available workspaces | | get_selected_workspace() | Get the active workspace |

Common Mistakes

| Mistake | Fix | |---------|-----| | Wrong URL (using SSE endpoint) | Use https://mcp.render.com/mcp (not /sse) | | Expired or invalid API key | Generate a new key from Dashboard > Account Settings > API Keys | | Wrong workspace selected | Run list_workspaces() and switch to the correct one | | Using MCP to create image-backed services | Not supported — use Dashboard or API for prebuilt Docker images | | Missing Bearer prefix in auth header | Header must be Authorization: Bearer <key> |

Troubleshooting

See references/troubleshooting.md for connection errors, auth failures, timeout issues, and tool-specific quirks.
