An MCP server that operates as a RenderDoc UI extension. An AI assistant accesses RenderDoc capture data and assists with graphics debugging.

Overview

An MCP server that operates as a RenderDoc UI extension. An AI assistant accesses RenderDoc capture data and assists with graphics debugging. Since Python built into RenderDoc lacks a socket module, communication is performed via file-based IPC. Extensions are installed at %APPDATA%\qrenderdoc\extensions\renderdoc_mcp_bridge. 1. Launch RenderDoc 2. Tools > Manage Extensions 3. Enable "RenderDoc MCP Bridge" : --editable will immediately reflect changes to the source code (convenient during development). If installing as a stable version, use uv tool install . . 1. Launch RenderDoc and open the capture file (.rdc). 2. Access RenderDoc data from an MCP client (such as Claude) : Operation verification is only conducted on Windows + DirectX 11 environments. It may also work on Linux/macOS + Vulkan/OpenGL environments, but this has not been verified.

Architecture

Since Python built into RenderDoc lacks a socket module, communication is performed via file-based IPC.

Setup

1. Installing the RenderDoc extension

Extensions are installed at %APPDATA%\qrenderdoc\extensions\renderdoc_mcp_bridge.

2. Enabling extensions with RenderDoc

Launch RenderDoc
Tools > Manage Extensions
Enable “RenderDoc MCP Bridge”

3. Installing the MCP server

Restarting the shell makes the renderdoc-mcp command usable.

Note: Adding --editable instantly reflects changes to the source code (useful during development). Use uv tool install . when installing as a stable version.

4. Configuring the MCP Client

How to Use

Launch RenderDoc and open the capture file (.rdc)
Access RenderDoc data from MCP clients (such as Claude)
