Render MCP Server

Overview

The Render MCP Server is a Model Context Protocol (MCP) server that allows you to interact with your Render resources via LLMs.

Getting Started

Get started with the MCP server by following the official docs: https://render.com/docs/mcp-server

Protocol Support

The server supports Streamable HTTP and stdio with MCP protocol versions 2025-11-25, 2025-06-18, 2025-03-26, and 2024-11-05. Stdio also supports the sessionless protocol 2026-07-28. Streamable HTTP requires the initialize handshake with one of the versions listed above.

Use Cases

• Creating and managing web services, static sites, cron jobs, and databases on Render
• Monitoring application logs and deployment status to help troubleshoot issues
• Monitoring service performance metrics for debugging, capacity planning, and optimization
• Querying your Postgres databases directly inside an LLM

Feedback

Please leave feedback via filing a GitHub issue if you have any feature requests, bug reports, suggestions, comments, or concerns.

Tools

Workspaces

• list_workspaces - List the workspaces that you have access to

  • No parameters required

• select_workspace - Select a workspace to use

  • ownerID: The ID of the workspace to select (string, required). Kept as ownerID so existing callers of this deprecated tool keep working; new code should pass workspaceId on each resource tool call instead.

• get_selected_workspace - Get the currently selected workspace

  • No parameters required

Every resource tool also accepts an optional workspaceId. After the user confirms a workspace from list_workspaces, pass that workspaceId on each related tool call. This keeps the target workspace explicit across MCP reconnects and transport-session changes. If workspaceId is omitted, the server temporarily falls back to the workspace selected in the current MCP session. That implicit session-based behavior is deprecated and is scheduled for removal.

  • cursor: A unique string that corresponds to a position in the result list. If provided, the endpoint returns results that appear after the corresponding position. To fetch the first page of results, set to the empty string (string, optional).

  Events cover services only, not Postgres or Key Value instances. The 7 day default applies to the first page only. For older events, page with the cursor from the previous call; if the first page comes back empty there is no cursor to follow, so set an earlier startTime instead.

The hosted MCP server doesn't have IP addresses you can allowlist yet; to query an IP-restricted database, run the MCP server locally and add your IP address to the allowlist.
