Is SindByte free?

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

For business, team or commercial use, the right way is through Smart Package Robot License.

Why does my client show fewer tools than the website?

Because the website documents the audited 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 unblock an entire category, publish only its essential tools, or hide them 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 provides include_schema=true the full schemes.
• ToolCatalog.GetToolSchema returns the schema for a concrete tool.
• ToolCatalog.CallTool executes the target tool by name.
• With IQTools, short mode removes the core aliases BetterPrompt and Validate out. Stand at MemoryTools Recall and Store in 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 provides the activated tool routes itself tools/list ready so that clients can access them directly.

• This mode is convenient for clients who prefer to see a broad direct tool list.
• ToolCatalog.* Auxiliary routes may still exist, but are not the only route of execution.
• 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 remains in tools/list hidden.

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.
• Put a usable one 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 GUI and 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 live screenshots from the running Windows application and explainer images provided via CUTools::GenerateImage were generated. The new FAQ and Config visuals on this page come directly from the running server.
