Upload HTML through MCP.

Local file uploads · Recommended

1. Create a separate credential in MCP connections. Reading and uploading are enabled by default.
2. Download the local adapter, and extract it to a stable directory. Requires Python 3.12+ with no additional dependencies.
3. Configure a stdio MCP server in your AI client and specify the directories it may read.

{
  "mcpServers": {
    "6hl": {
      "command": "python3",
      "args": ["/absolute/path/6hl-mcp/sixhl_mcp.py"],
      "env": {
        "SIXHL_URL": "https://6hl.dad",
        "SIXHL_TOKEN": "Your separate MCP credential",
        "SIXHL_ALLOWED_DIRS": "/absolute/path/to/your/works"
      }
    }
  }
}

Configuration varies between clients. Store the credential in private local configuration or a system credential store, never inside a project file.

For uploads, provide the file path, project name and idempotency key. For updates, also provide the project ID and current revision. Files must be within an explicitly allowed directory.
