MCP and Claude Setup

From first install to productive AI sessions in minutes.

Home → AI Integration → MCP and Claude Setup

Together, the skill conditions Claude's behavior before the first tool fires, and MCP gives Claude the tools to act on that knowledge. The result is an AI Designer that truly understands the platform and builds solutions correctly from the first response.

What You Need

Standard Setup

Step 1: Install Claude Desktop

Download the Claude here: Claude Download

Step 2: Install the Claude Skill

The Claude Skill is a portable SKILL.md file that follows the Agent Skills open standard. Install it once — it activates automatically whenever you mention FrameworX, SCADA, HMI, or related topics.

1. Install FrameworX
2. Go to Documents\FrameworX\AISetup    
3. Locate the frameworx.skill

Then, on Claude Desktop:

1. Go to Menu > File > Settings...
2. Go to Capabilities > Skills > Go to Customize
3. Click the '+' button, then "Upload a skill"
4. Select "frameworx.skill"
5. Make sure the skill toggle is set to On
6. Close the Settings window — the skill is now active for all future conversations

Step 3: Install the MCP Bundle

The MCP Bundle is four .mcpb files that install the FrameworX MCP tools into Claude Desktop with one click — no manual configuration needed.

Prerequisites: FrameworX Designer v10.1.3+ must be installed first. The MCP bundle ships with the product installation. The AI Designer, AI Console and AI Runtime extensions need the .NET Runtime 10.0 (10.1.5 and later; the Desktop Runtime also works).

The .mcpb files are located at Documents\FrameworX\AISetup. Repeat the procedure below for EACH of these files:

• frameworx-designer-mcp.mcpb
• frameworx-console-mcp.mcpb
• frameworx-runtime-mcp.mcpb
• frameworx-filesystem.mcpb

1. Open Claude Desktop
2. Go to Menu > File > Settings... > Extensions
3. Click Advanced Settings
4. Click Install Extension
5. Select the .mcpb file
6. Click Install
7. Click Install again on the confirmation popup
8. Close the Settings window — the connector is now active for all future conversations

Windows on ARM64

On Windows on ARM64 (for example Windows 11 in Parallels on a Mac), install both the ARM64 and the x64 .NET Runtime 10.0:

• ARM64: the MCP servers start with dotnet, which on ARM64 is the ARM64 .NET host. That host does not use an x64 runtime.
• x64: Multiplatform solutions started from Designer or Solution Center run on it.

winget install --id Microsoft.DotNet.Runtime.10 --architecture arm64
winget install --id Microsoft.DotNet.Runtime.10 --architecture x64

Check. Run dotnet --list-runtimes and look for a Microsoft.NETCore.App 10. line whose path has no x64 folder. A 10.x runtime only under C:\Program Files\dotnet\x64\ is the x64 runtime, which dotnet does not use on ARM64.

Symptom. Without the ARM64 runtime, the AI Designer, AI Console and AI Runtime servers close as soon as they start, Claude reports "Connection closed", and no FrameworX tool is available. Running dotnet ConsoleMCP.dll from fx-10\net10.0\ prints "You must install or update .NET to run this application" with "Architecture: arm64". Fix: install the ARM64 runtime, then fully quit Claude Desktop and open it again.

Step 4: Set Permissions and Verify

After installing the four extensions, follow the Set Permissions and Verify procedure in the Appendix for each one.

Advanced: Different Computers

Use this when Claude Desktop and FrameworX Designer run on different machines — for example, Claude Desktop running on a Mac with FrameworX Designer inside a Windows virtual machine (Parallels, VMware), or FrameworX running on a separate Windows computer on the network.

In this setup, DesignerMCPHttp runs as a lightweight HTTP server on the Windows machine. On the client machine you install the HTTP variant of the extension bundle, which carries the mcp-remote bridge configuration for you — there is no configuration file to edit by hand. All communication happens exclusively through the MCP tools; no shared folders or filesystem server is needed.

Prerequisites:

• FrameworX Designer v10.1.3+ installed on the Windows machine
• Claude Desktop installed on the client machine
• Node.js (LTS version) installed on the client machine — the HTTP bundle runs the mcp-remote bridge, which is an npm package

Step 1: Start DesignerMCPHttp on the Windows Machine (Server)

On the Windows machine where FrameworX is installed:

1. Open File Explorer and navigate to your Documents folder: Documents\FrameworX\Utilities
2. Double-click StartDesignerMCPHttp.bat

You should see a console window confirming the server is listening on port 10150. Leave this window open — the server must stay running.

From FrameworX 10.1.6, set X_API_KEY in DesignerMCPHttp.json (see Server Settings below) before you start the server: without a key it listens on this computer only and the client machine cannot connect.

Important: The MCP server must be started before Claude Desktop. If you ever restart the server, you must also restart Claude Desktop.

Step 2: Install the HTTP Extension on the Claude Desktop Machine (Client)

Remote access uses the HTTP variant of the bundle. The files are in Documents\FrameworX\AISetup on the FrameworX machine — copy the one you need to the client machine if the two do not share a folder.

Install it exactly as in the standard setup:

1. Open Claude Desktop
2. Go to Menu > File > Settings... > Extensions
3. Click Advanced Settings
4. Click Install Extension
5. Select the .mcpb file
6. Click Install
7. Click Install again on the confirmation popup

Step 3: Point the Extension at the Server Machine

1. Go to Menu > File > Settings... > Extensions
2. Find FrameworX AI Designer (HTTP) in the list and click Configure
3. Set DesignerMCPHttp Host to the address of the Windows machine
4. Set DesignerMCPHttp Port only if you changed ListenPort on the server (default 10150)
5. Set API Key to the server’s X_API_KEY value (FrameworX 10.1.6 and later — required for any connection from another machine; leave it empty only when Claude Desktop and FrameworX run on the same computer)

Which host address to use:

• FrameworX in a VM on the same host (Parallels or VMware on a Mac): use 127.0.0.1. You may need to configure VM port forwarding to route port 10150 from the host to the Windows guest.
• FrameworX on a different computer on the network: use that machine's IP address, for example 192.168.1.50. Make sure port 10150 is open in Windows Firewall on the FrameworX machine.

Step 4: Restart Claude Desktop

For changes to take effect, follow the Restart Claude Desktop procedure in Appendix.

Step 5: Set Permissions and Verify

Follow the Set Permissions and Verify procedure in the Appendix for each extension you installed.

Server Settings: Port, API Key, and HTTPS

DesignerMCPHttp reads its settings from DesignerMCPHttp.json in the FrameworX installation folder:

C:\Program Files\Tatsoft\FrameworX\fx-10\net10.0\DesignerMCPHttp.json

Edit this file before starting the server. From FrameworX 10.1.6, the shipped defaults accept connections from the local machine only. In 10.1.5, the shipped defaults work for a trusted local network.

{
  "appSettings": {
    "X_API_KEY": "",
    "CertFileName": "",
    "CertPass": "",
    "CertHash": "",
    "ListenPort": "10150"
  }
}

Where:

Advanced: GitHub Copilot (VS Code)

Use this setup if you prefer to work with GitHub Copilot inside Visual Studio Code instead of Claude Desktop. The FrameworX MCP tools work the same way — the only difference is the client.

Prerequisites:

• Visual Studio Code installed
• GitHub Copilot extension installed in VS Code (Ctrl+Shift+X → search "GitHub Copilot" → Install)
• GitHub account with an active Copilot subscription (free tier available at github.com/features/copilot)
• FrameworX Designer v10.1.3+ installed
• Cross-platform .NET Desktop Runtime matching your FrameworX version (.NET 8 for 10.1.4 and earlier, .NET 10 for 10.1.5 and later)

Step 1: Sign in to GitHub Copilot

After installing the extension, sign in using:

• The Copilot icon in the bottom-right status bar → click and follow the prompt, or

A browser window will open for GitHub authentication. Once complete, the Copilot icon in the status bar turns solid, confirming it's active.

Step 2: Configure the MCP Servers

Open the Command Palette (Ctrl+Shift+P) and run:

MCP: Open User Configuration

This opens (or creates) your global mcp.json file. Replace the contents with the following. Adjust the runtime folder in the DesignerMCP.dll path to match your FrameworX version (net8.0 for 10.1.4 and earlier, net10.0 for 10.1.5 and later):

{
  "servers": {
    "FrameworX-Designer": {
      "type": "stdio",
      "command": "dotnet",
      "args": [
        "C:\\Program Files\\Tatsoft\\FrameworX\\fx-10\\net10.0\\DesignerMCP.dll"
      ]
    },
    "filesystem": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "-p",
        "@modelcontextprotocol/server-filesystem@2025.8.21",
        "-p",
        "zod@3.25.76",
        "-p",
        "@modelcontextprotocol/sdk@1.32.1",
        "mcp-server-filesystem",
        "C:\\Users\\Public\\Documents\\FrameworX\\Exchange"
      ]
    }
  }
}

Save the file.

Step 3: Start the MCP Servers

After saving the file, open the Command Palette (Ctrl+Shift+P), run MCP: List Servers, select each server, and choose Start Server to initialize it and discover the available tools.

Step 4: Use in Copilot Chat

1. Open Copilot Chat (Ctrl+Alt+I or click the Copilot icon in the sidebar)
2. Switch the chat mode to Agent using the dropdown at the bottom of the chat panel

Test it: Ask "List my available FrameworX solutions" — Copilot should call list_solutions and return the results.

Step 5: Set Tool Permissions

On the first session, GitHub Copilot will ask for confirmation before each tool call. Select Allow Always when prompted for each tool to avoid repeated approvals in future sessions.

Advanced: ChatGPT / Codex

Use this setup if you prefer to work with OpenAI Codex (desktop app or CLI) instead of Claude Desktop. The FrameworX MCP tools work the same way — the only difference is the client. We still recommend Claude for the best FrameworX experience; use this path only if your team is standardized on ChatGPT / Codex.

Prerequisites:

• OpenAI Codex (desktop app or CLI) installed and signed in
• FrameworX Designer v10.1.3+ installed
• Cross-platform .NET Desktop Runtime matching your FrameworX version (.NET 8 for 10.1.4 and earlier, .NET 10 for 10.1.5 and later)

Step 1: Register the FrameworX MCP Server

The codex executable is not always on your PATH. Open a terminal, navigate to the folder containing codex.exe, then run:

codex mcp add FrameworX-Designer -- dotnet "C:\Program Files\Tatsoft\FrameworX\fx-10\net10.0\DesignerMCP.dll"

Adjust the runtime folder (net8.0 vs net10.0) to match your FrameworX version. This registers the server globally — no manual config file editing needed.

Step 2: Verify the Server Is Registered

From the same folder, run:

codex mcp list

FrameworX-Designer should appear with status enabled.

Alternatively, verify from the Codex UI: Edit > Settings > Plugins > MCPs > FrameworX-Designer should appear in the list.

Step 3: Restart Codex / ChatGPT

Fully quit the ChatGPT / Codex process, then reopen it.

Step 4: Test It

Test it: Ask "Use FrameworX AI Designer connector to list the available solutions." Codex should call list_solutions and return the results.

Advanced: Google Antigravity

Antigravity is Google's agent platform (desktop app, IDE and CLI). The FrameworX MCP tools work the same way: the only difference is the client.

Prerequisites:

• Google Antigravity installed and signed in with your Google account
• FrameworX Designer v10.1.3+ installed
• Cross-platform .NET Desktop Runtime matching your FrameworX version (.NET 8 for 10.1.4 and earlier, .NET 10 for 10.1.5 and later)

Step 1: Open the MCP Configuration File

Antigravity reads its MCP servers from a global configuration file:

%USERPROFILE%\.gemini\config\mcp_config.json

If the config folder or the file does not exist, create them. In the Antigravity IDE, you can also open this file from the agent side panel: click ... at the top of the panel, then MCP Servers > Manage MCP Servers > View raw config.

Step 2: Add the FrameworX MCP Server

Replace the contents of the file with the following. Adjust the runtime folder in the DesignerMCP.dll path to match your FrameworX version (net8.0 for 10.1.4 and earlier, net10.0 for 10.1.5 and later):

{
  "mcpServers": {
    "FrameworX-Designer": {
      "command": "C:\\Program Files\\dotnet\\dotnet.exe",
      "args": [
        "C:\\Program Files\\Tatsoft\\FrameworX\\fx-10\\net10.0\\DesignerMCP.dll"
      ]
    }
  }
}

Save the file.

Step 3: Reload and Verify

Restart Antigravity. To confirm the server was loaded:

• Antigravity app: go to Settings > Customizations. FrameworX-Designer should appear under Installed MCP Servers. The refresh button in that section reloads the configuration without restarting.
• Antigravity CLI: run agy mcp list. FrameworX-Designer should appear with status enabled.

Step 4: Set Tool Permissions

By default, Antigravity asks for approval before each MCP tool call, which breaks longer building sessions. To allow all FrameworX tools at once, add this permission rule:

mcp(FrameworX-Designer/*)

• Antigravity app: add the rule in Settings > General > Permission Settings.
• Antigravity CLI: add the rule to %USERPROFILE%\.gemini\antigravity-cli\settings.json:

{
  "permissions": {
    "allow": [
      "mcp(FrameworX-Designer/*)"
    ]
  }
}

Step 5: Test It

Test it: Open a new conversation and ask "Use the FrameworX-Designer MCP server to list my available FrameworX solutions." Antigravity should call list_solutions and return the results.

Appendix

Set Permissions and Verify

  Repeat this procedure for EACH of the following extensions:
    - FrameworX AI Designer
    - FrameworX AI Console
    - FrameworX AI Runtime
    - FrameworX File Access

Set Tool Permissions

Without this step, Claude will ask you to approve every single tool call, which breaks longer building sessions.

1. Go to Menu > File > Settings... > Extensions
2. Find the extension in the list
3. Click "Configure"
4. Set Tool Permissions to Always Allow
5. Close the Settings window — the permissions now are set

Verify It Works

1. In Settings → Developer, verify that FrameworX AI Designer, FrameworX AI Console, FrameworX AI Runtime, and FrameworX File Access all show status "running"
2. Open a new chat and Click the '+' button, then Connectors, all four extension tools should appear in the list

Test it: Open a new conversation and ask "Create a new FrameworX solution with a bottling line" — Claude should immediately start building, calling create_solution and writing objects.

You're done! Jump to Next Steps.

Restart Claude Desktop

1. Fully close Claude Desktop:
   • Windows: Right-click the Claude icon in the system tray and click Quit, or end it via Task Manager (Ctrl + Shift + Esc).
   • macOS: Right-click the Claude icon in the Dock and click Quit, or press Cmd + Q.
2. Relaunch Claude Desktop.

Best Practices

Building Large Solutions

When creating a solution with many tags, devices, and displays, we recommend breaking the work into smaller steps rather than trying to build everything in a single prompt. Start by describing the full solution to give the AI context, then build each part separately. If you run out of tokens mid-conversation, start a new chat and ask the AI to review what was created so far before continuing.

Recommended workflow:

1. Describe the entire solution scope (without building anything yet)
2. Create the tag structure (UNS hierarchy)
3. Configure Alarms and Historian
4. Build the first display
5. Build additional displays one at a time
6. Continue with remaining components (scripts, reports, etc.)

Prompt Structure

For best results, structure your prompts using clearly defined sections: role, context, instructions. The example below shows a basic well-structured prompt.

Tell the AI its role (e.g., "You are a FrameworX automation engineer...")

<context>
Describe your project context: what the solution does,
which protocols and devices are involved, tag naming conventions, etc.
</context>

<instructions>
Provide step-by-step instructions for what you want built.
Be specific about naming, structure, and preferences.
</instructions>

For a comprehensive guide on prompt engineering techniques, see: Claude – Prompting Best Practices and AI Designer Best Practices.

Model Recommendation

We recommend using Claude Sonnet without Extended Thinking. Sonnet provides the best balance between speed and quality for FrameworX MCP workflows.

Troubleshooting

Quick Reference: File Locations

Change for release 10.1.5

The skill bundle filename changed. Earlier releases shipped frameworx-industrial-platform.skill. Starting with FrameworX 10.1.5, the bundle is named frameworx.skill (same location: Documents\FrameworX\AISetup).

Fresh installs — follow Step 2 above using frameworx.skill instead of frameworx-industrial-platform.skill.

Upgrading from 10.1.4 or earlier:

1. Open Claude Desktop → Settings → Capabilities → Skills → Customize
2. Find the legacy frameworx-industrial-platform skill in the list, click it, and remove it
3. Click + → Upload a skill → select frameworx.skill from Documents\FrameworX\AISetup
4. Make sure the new skill toggle is set to On
5. Fully quit Claude Desktop and re-open (skills are cached for the life of the process)

Skipping the cleanup loads both the old and new skills, which can produce inconsistent behavior.
