Frequently Asked Questions

Is SindByte free?

Yes, SindByte is free for private use. Private users can download the ZIP directly and run the local MCP runtime on their own Windows computer.

For business, team or commercial use, the right path is the Smart Package Robot license. The short version is in the section License, Download and Trust.

Why does my client show fewer tools than the website?

Because the website documents the default product interface and not just a single runtime snapshot. The live server only publishes what the current machine, credentials, feature flags, category filters and registration mode allow.

• Feature flags can activate tools, have them confirmed first, or deactivate them completely.
• Registration filters can enable an entire category, publish only its essential tools, or hide it completely.
• Credential-bound families such as Gmail, M365, Teams, Trading Connectors and Image Routes remain invisible until usable keys are available.
• Short registration intentionally compresses the visible surface.

What is Short Registration?

Short registration is the compact publication mode. Instead of outputting each tool as a long direct list, the server emphasizes categories and bridge routes.

• ToolCatalog.ListCategories lists the actively published categories.
• ToolCatalog.ListTools lists tools within a category and returns the full schemas with include_schema=true.
• ToolCatalog.GetToolSchema returns the schema for a concrete tool.
• ToolCatalog.CallTool executes the target tool by name.
• For IQTools, short mode highlights the core aliases BetterPrompt and Validate. For MemoryTools, Recall and Store take the foreground.

{
  "tool_name": "MathTools::ResolveFormula",
  "arguments": { "formula": "4+66" }
}

What is Full or Long Registration?

Full registration is the direct publication mode. The server itself provides the activated tool routes in tools/list, so that clients can call them directly.

• This mode is convenient for clients who prefer to see a broad direct tool list.
• ToolCatalog.* helper routes may still exist but are not the only way to execute tools.
• The visible schema surface becomes larger and more detailed.
• If you want the broadest client list, use full mode and leave the required categories active.

What do ON, ESSENTIAL and OFF mean in Registration Filters?

• ON: the activated tools in this category are published.
• ESSENTIAL: only the tools in this category that are marked as essential will be published.
• OFF: the category stays hidden in tools/list.

That's why two installations with the same code can still show significantly different client catalogs.

Why are image tools missing or failing?

• Check whether an OpenAI key is saved in the Config Editor.
• Activate OpenAIImageToolEnabled.
• Set a usable OpenAIImageModel, for example gpt-image-1.
• Make sure registration mode and category filters continue to publish image routes.
• Reload the client after changes to update the cached schema.

Do I always have to reload the client after configuration changes?

Practically yes. Many MCP clients cache the published schema longer than expected. After changes to feature flags, credentials, registration mode, or category filters, the client should be reloaded before suspecting a server error.

Where is the configuration?

The active configuration is in mcp_config.json. The Config Editor writes the exact same file that the server reads. So the GUI and the runtime work on the same feature-flag and provider model.

This is precisely why this website can honestly describe the runtime instead of treating UI and server like two separate products.

Was this documentation created using the server itself?

Yes. This site update uses screenshots from the running Windows application and explainer images generated via CUTools::GenerateImage. The new FAQ and Config visuals on this page come directly from the running server.
