@rendobar/mcp

Rendobar — serverless media processing for AI agents.

@rendobar/mcp is the official Model Context Protocol server for Rendobar. It lets AI agents in Claude Desktop, Cursor, Cline, Windsurf, Zed, VS Code, Claude Code, and Continue submit Rendobar jobs and upload local files in a single tool call.

Install

You don't install it. Configure your MCP client to spawn it via npx.

Get an API key

Sign up at app.rendobar.com → Settings → API Keys.

Configure your client

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "rendobar": {
      "command": "npx",
      "args": ["-y", "@rendobar/mcp"],
      "env": { "RENDOBAR_API_KEY": "rb_..." }
    }
  }
}

Restart Claude Desktop.

Cursor

Edit ~/.cursor/mcp.json or <project>/.cursor/mcp.json. Same schema as Claude Desktop.

Cline (VS Code extension)

Open Cline's MCP panel → Configure → paste the same mcpServers block.

Windsurf

Edit ~/.codeium/windsurf/mcp_config.json. Same schema.

Zed

Edit ~/.config/zed/settings.json:

{
  "context_servers": {
    "rendobar": {
      "source": "custom",
      "command": "npx",
      "args": ["-y", "@rendobar/mcp"],
      "env": { "RENDOBAR_API_KEY": "rb_..." }
    }
  }
}

VS Code (1.101+)

Edit .vscode/mcp.json:

{
  "servers": {
    "rendobar": {
      "command": "npx",
      "args": ["-y", "@rendobar/mcp"],
      "env": { "RENDOBAR_API_KEY": "${input:rendobarKey}" }
    }
  },
  "inputs": [{ "id": "rendobarKey", "type": "promptString", "password": true, "description": "Rendobar API Key" }]
}

Claude Code (terminal)

claude mcp add rendobar -s user --env RENDOBAR_API_KEY=rb_... -- npx -y @rendobar/mcp

Continue

Create .continue/mcpServers/rendobar.yaml:

type: stdio
command: npx
args: ["-y", "@rendobar/mcp"]
env:
  RENDOBAR_API_KEY: rb_...

Tools

| Tool | Purpose | |---|---| | upload_file | Upload a local file. Returns a download URL to use in submit_job. | | submit_job | Submit any Rendobar job. Description lists active job types. | | get_job | Poll job status, fetch result. | | list_jobs | List recent jobs. | | cancel_job | Cancel a waiting/dispatched job. | | get_account | Check balance, plan limits, active job count. |

Authentication

Three sources, first match wins:

1. --api-key=<key> flag
2. RENDOBAR_API_KEY environment variable
3. ~/.config/rendobar/credentials.json (Unix) / %APPDATA%\rendobar\credentials.json (Windows) — written by Rendobar CLI's rb login (CLI v1.1+)

Troubleshooting

Cursor on macOS (Dock launch) can't find npx

Cursor launched from the Dock has the GUI PATH, not the shell PATH. Use the absolute path to npx in your mcp.json:

"command": "/Users/you/.nvm/versions/node/v20.x/bin/npx"

Windows: npx not found

Use "command": "npx.cmd" instead of "command": "npx" if your client doesn't auto-resolve.

Server fails to start

Check logs in your client's output panel. Server writes JSON lines to stderr — look for entries with level: "error".
