Change Release Notes

Introducing one of the World's most important robot platform AI integrations ever:

User-inserted image

Model Context Protocol support.

ARCx can now expose robot capabilities to compatible AI clients through an integrated MCP server, creating a standardized bridge between artificial intelligence and the real-world capabilities available inside your ARCx project.

Read manual here: https://synthiam.com/Support/ai-integration/Model-Context-Protocol

Your robot already has cameras, motors, sensors, speech, scripts, and Robot Skills.

Now AI can have a structured way to discover and interact with them.

New Model Context Protocol Server

ARCx now includes an integrated MCP server that can be enabled directly from the application.

MCP - Model Context Protocol - provides a standardized way for AI systems to discover tools, resources, and capabilities exposed by other applications.

In ARCx, that means compatible AI clients can interact with the functionality you choose to make available from your robot project.

This opens the door to AI that can do more than simply talk about your robot.

It can potentially use the robot's capabilities as tools. And it gets even better. Your selected AI can also add robot skills, configure robot skills, and run projects. You can watch an entire robot project get built in real time as the AI adds and configures it based on your specifications. Instruct the AI to build a robot project and describe your ports, servos, motors, and configuration.

Turn Robot Skills Into AI Tools

ARCx Robot Skills already provide the building blocks for real-world robot functionality.

Movement.

Vision.

Audio.

Speech.

Sensors.

Automation.

Custom hardware.

With MCP, ARCx can expose selected capabilities to AI clients in a way they can understand and invoke.

That creates an exciting foundation for experiences where an AI can reason about a task and then ask ARCx to perform the appropriate real-world action.

AI provides the intelligence.

ARCx provides the robot.

You Control What AI Can Access

Connecting AI to a robot shouldn't mean handing it the keys to everything.

ARCx includes new MCP configuration controls that let you decide how the server operates and what AI clients are allowed to access.

The new settings include controls for:

  • Enabling or disabling the MCP server
  • Configuring an access token
  • Managing AI permissions
  • Controlling exposed tools and resources

This keeps the integration flexible while allowing developers to decide exactly how much control an AI client should have.

Access Token Protection

The MCP server can be protected with an access token, helping prevent unauthorized clients from connecting to ARCx.

That becomes especially important when ARCx is running on a network or when the robot exposes capabilities that can affect hardware in the physical world.

AI connectivity is useful.

Controlled AI connectivity is much better.

New MCP Documentation

Documentation has been expanded to explain how ARCx's MCP tools and resources work and how Robot Skills can expose functionality to AI clients.

This gives robot skill developers a clearer path toward building capabilities specifically designed for AI-driven robotics.

We're not just adding an AI button.

We're building an interface between AI systems and the ARCx robotics ecosystem.

Better robot skill Management

Robot Skill management also received a major usability improvement in this release.

Installed Robot Skills are now organized into clearer groups such as:

  • Update Available
  • Private
  • Public

ARCx dynamically categorizes installed skills based on their current status and available store versions, making it much easier to see what needs attention.

Instead of hunting through one long collection of skills, you can immediately see what's installed, what's private, and what has an update waiting.

Robot Skill Manuals Now Open Inside ARCx

Robot Skill documentation is also much easier to access.

Clicking a robot skill can now open its manual directly inside a popup dialog in ARCx instead of launching a separate browser tab.

That means you can:

Read the instructions.

Close the dialog.

Keep building.

No tab juggling required.

The embedded manual also respects your selected ARCx theme for a more consistent experience.

Cleaner Debug Logging

ARCx logging received some cleanup as well.

Log formatting has been refined to include useful method information where appropriate while omitting internal details that don't add value.

The result is cleaner diagnostic output that's easier to scan when you're trying to figure out what your robot is doing.

Because debugging robots is already interesting enough without the logs fighting back.

Updated robot skill Template

The robot skill template has also been updated for this release, ensuring new Robot Skills start from the latest ARCx foundation.

Project files, installer configuration, and release versioning have all been updated for v2026.10.10.00.


The Robot Just Became an AI Tool

ARCx has always been about connecting software intelligence to real hardware.

With Model Context Protocol support, that connection becomes much more interesting.

An AI can understand the tools ARCx exposes.

ARCx can connect those tools to Robot Skills.

Robot Skills can control the physical world.

That's the bridge.

AI thinks.

ARCx acts.

The robot does.

Outstanding addition to ARCx! MCP opens up tremendous possibilities for AI integration, real-time diagnostics, and smarter robotics. This is a significant step forward, and I'm excited to see where it leads. Thank you, Synthiam!

Thanks, man. It's pretty awesome. Watching a robot project get built right in front of you while Claude spins at it... It's amazing!

I have MCP working with ARCx and am still testing its capabilities. So far, Cursor can communicate with the ARCx project and create or update scripts directly, which is a pretty significant step forward. I'm not using it to control any robot hardware or execute actions yet, but I plan to continue testing and gradually expand what it can do. Lots of potential here. Really cool.

It can do the whole project entirely - it can add robot skills, create robot skills, edit robot skill configurations, build entire projects from scratch, access camera feeds, etc.

Both ARC and ARCx now contain MCP servers for this. The ARC MCP is a little more interesting because the AI agent actually interacts with the user interface by moving the mouse, clicking, opening menus, typing, etc. That is quite interesting to watch.

Dude, ask it to make a robot skill. Tell it what kind of robot skill you want. That's where it gets pretty amazing.

When you say create a Robot Skill, do you mean MCP can actually develop and install a completely new custom ARCx Robot Skill, with its own interface, settings, and functionality, rather than simply adding a Script skill?

Yes sir.

If you want a robot skill that does something. Ask it to do it. Keep in mind that we use Claude Code. I don't think anyone uses Cursor anymore

Oh wait - you don't have this version of ARCx yet. I'll have it pushed tonight. The latest one has robot skill creation MCP server support built in.
