Deep technology, ready for productive use

SindByte turns MCP into a real Windows workspace

SindByte is a local MCP server for Windows: your AI host calls real Windows tools over port 5555, for example inspecting files, controlling windows and taking screenshots. You decide which tools it gets to see.

See the licence supplied with the download. For business or commercial use, the right path is the Smart Package Robot license. License explained

Three areas: Compiler Workshop, AI Workshop, and Services

Futuristic engines of the Compiler Workshop

1. Compiler Workshop

One download, the PBX Compiler V10 package (about 355 MB), contains all current compilers: PBXB64 as the main compiler for PowerBASIC-compatible BASIC with native Windows x64 output, ScharffBasic V1 Beta as a mostly PowerBASIC-compatible 32-bit alternative, PBXA64, PBXA32 and the PBXC64 preview – plus reference help and 6,321 example sources.

Windows 10 x64 or newer. See the supplied licence; for business see License.

2. AI Workshop

SindByte MCP Server is the local runtime. WorkJinn runs AI work for real Windows projects: documentation, bounded code changes, tests and validation evidence. PlanJinn V5 turns a description into a verified Windows program: it plans in stages, writes the code, builds it with the built-in PBXB64 compiler and checks the result.

Windows 10 or 11, at least 4 GB RAM. You need an MCP-capable AI client, for example LM Studio.

3. Services

Practical support for businesses: AI revenue audits, automation sprints, team training, an AI freelancer/instructor, and custom development for real-world processes.

Models and browser games

These additional offers complement our three main areas. They have their own collections, so new models and several games can be added without making the home page crowded.

Ecosystem Overview

Compiler Workshop, AI Workshop, and Services under one brand

SindByte ecosystem diagram with Compiler Workshop and AI Workshop

Compiler Workshop, AI Workshop, and Services share the same local-first philosophy: native Windows tools under operator control.

Positioning for private users and business teams

A clear offering

Private users download SindByte directly. Business rollouts, teams, and commercial use follow the Smart Package Robot licensing path.

Publish the catalog deliberately

The visible MCP catalog can start small and grow later. Registration, category filters, and credentials provide deliberate control.

Local first

The default is 127.0.0.1:5555. Cloud, Office, and trading routes remain optional and become relevant only with real credentials.

MCP-capable hosts

LM Studio, Roo Code, Codex workflows, and VS Code add-ons can use the same runtime without tying the product to a single chat interface.

Architecture and runtime in four clear layers

1. Host

An MCP-capable client sends requests to the local endpoint. The product remains host-agnostic.

2. Endpoint

The default endpoint is http://127.0.0.1:5555/mcp. This keeps the runtime local and technically transparent.

3. Registration

Short or Full registration, plus category filters and feature flags. As a result, not every host sees the same set of tools.

4. Execution

Files, windows, timers, image workflows, and credential-dependent families come together in a controlled Windows runtime.

Technical live screenshot of the Config Editor
The runtime is not inferred behind the scenes. It is actively shaped in the Config Editor through port, registration, filters, providers, and features.

Suitable host patterns

LM Studio

Ideal when local inference and local tool execution should run on the same PC without external dependencies for core automation.

Roo Code / Cline

Suitable for repository work, file changes, data cleanup, screenshots, and bounded system actions with ask-first protection.

Custom MCP clients

Internal tools can use the same streamable HTTP endpoint and limit the visible catalog through the runtime configuration.

Clients using Short Registration

A compact ToolCatalog entry point suits hosts that should not load hundreds of direct tool schemas at once.

Visual guides to connection and runtime behavior

Host ecosystem around SindByte

One endpoint for multiple host types

The runtime remains MCP-centered rather than tied to a single chat client. This helps with adoption, testing, and internal standardization.

Diagram of registration modes

Short and Full at a glance

The diagram shows the difference between broad direct publication and a more compact ToolCatalog-oriented approach.

Diagram of runtime surfaces

Product surfaces, not just an endpoint

The runtime includes server shell, configuration, chat, and timer surfaces. That is what makes SindByte tangible as a product.

What ships with the runtime

SindByte runtime registration modes

Main server shell

Starts the local endpoint, displays status and logs, and provides the operational entry point to the product surfaces.

SindByte runtime product surfaces

Config Editor

Controls the port, local-only behavior, registration, categories, feature flags, provider access, timeouts, and logging.

MCP host ecosystem

Dialog-LAB

A workspace for structured model dialogues and handoffs between specialized reasoning and execution steps.

LMChat

A lightweight local chat interface for fast model and tool loops.

Timer + IQ

Schedules recurring tasks and connects them with the runtime's reasoning and execution helpers.

Trading Hub

A credential-dependent example interface for controlled external services; it remains optional without configured access.

Where SindByte delivers practical value

Local repository and file operations

Inspect files, organize content, and perform bounded changes directly on the Windows workstation.

Desktop and UI automation

Windows, screenshots, and controlled interaction flows with ask-first rules instead of uncontrolled remote operation.

Scheduled checks and monitoring

Timers connect recurring reviews, observations, and local execution through traceable workflows.

Credential-aware connectors

Cloud images, email, and other services become active only when real credentials and the appropriate categories are enabled.

Launch and connection examples

Start on Windows

cd "<extracted-folder>"
.\SindByte 01.exe

The local client endpoint is then http://127.0.0.1:5555/mcp.

Host configuration

"mcpServers": {
  "sindbyte": {
    "type": "streamable-http",
    "url": "http://127.0.0.1:5555/mcp"
  }
}

A safe first step

ToolCatalog.ListCategories
ToolCatalog.ListTools
spr_server_assistant

This lets you inspect the currently published runtime first instead of assuming the entire default configuration is exposed.

Verifiable facts instead of marketing claims

Port and host

The default is 127.0.0.1:5555. This makes the local host a clear, testable setup characteristic.

Registration modes

Short and Full determine whether many routes are published directly or through a more compact ToolCatalog approach.

Filters and credentials

The visible catalog intentionally varies according to category filters, security flags, and configured credentials.

Product surfaces

Config Editor, Dialog-LAB, chat window, timer and IQ tools are part of the program; the screenshots above come from the product.
