Test queries (see examples below).

Installation of CAST Imaging MCP server

1) Extract the installer

text

com.castsoftware.imaging.mcpserver.docker.1.0.2-funcrel/
├─ config/
│  └─ app.config
├─ .env                      # hidden; use `ls -a`
├─ docker-compose.yml
├─ run.sh
├─ README.md
└─ copilot-instructions.md

2) Verify CAST Imaging‑APIs

Make sure the Control Panel/registry is reachable and Imaging‑APIs is ready (see Quick Start step #1).

3) Configure server

Edit config/app.config:

ini

HOST_CONTROL_PANEL="your-control-panel-host"   # REQUIRED: Control Panel service registry host/IP
PORT_CONTROL_PANEL=8098                        # Default Control Panel registry port
IMAGING_PAGE_SIZE=1000                         # Internal fetch batch size
IMAGING_DISPLAY_PAGE_SIZE=20                   # Page size in responses
IMAGING_CODE=False                             # Source code access via MCP (security sensitive)
DEBUG_MODE=false                               # Debug mode to see the activity in logs
IMAGING_DOMAIN="default"                       # Imaging domain/tenant
CONTROL_PANEL_SSL_ENABLED=false                # Set true only if Control Panel config/eureka is on HTTPS
MCP_TOOL_SURFACE_PROFILE="full"                # MCP tool exposure profile: "intents" or "full"
MCP_INTENTS_HIDDEN_FUNCTIONS=""                # Comma-separated structural functions hidden from intents mode
SERVICE_HOST="your-service-host"               # REQUIRED: The IP/hostname of the machine on which the MCP Server is running
SSL_CA_BUNDLE=""                               # Optional PEM bundle for private/self-signed CAs

Set your exposed port in .env (hidden file):

env

MCP_SERVER_PORT=8282

Tip: On Linux, files starting with a dot (like .env) are hidden. Use ls -a to view.

4) Start

bash

chmod +x run.sh
./run.sh --install

This launches the Docker Compose stack and the MCP server.

If you use SSL_CA_BUNDLE, place the PEM file in a certificates/ folder next to docker-compose.yml. The compose file mounts that folder into the container at /app/certificates.

Configuration Reference

`HOST_CONTROL_PANEL` (Required)

Default: None (user needs to provide the value)
Description: IP or hostname of the machine running the Control Panel Service.

This is a service registry used by Imaging to register and discover its internal services. It is automatically deployed when you install Imaging. You should enter the IP address of the Linux machine running the Imaging Control Panel service.

`PORT_CONTROL_PANEL`

Default: 8098
Description: Control Panel registry port.

`IMAGING_PAGE_SIZE`

Default: 1000
Description: Sets the number of records the MCP server fetches per request (internal batching). Tune for throughput.

`IMAGING_DISPLAY_PAGE_SIZE`

Default: 20
Description: Sets how many records are shown per page in the user-facing response. Tune for UX.

`IMAGING_CODE`

Default: False
Description: Controls whether the agent can access source code via the MCP server.

It's false by default, as agents typically work on open repos. Enabling it can expose source code to anyone with MCP access, making it a potential security risk, especially relevant for clients like Claude desktop without direct repo access.

`DEBUG_MODE`

Default: false
Description: Debug mode will show teh activity in the logs. When set to true it will show the tool picked, the API called and the result for each user prompt. When set to false, it will only show the tool picked and the corresponding API called.

`IMAGING_DOMAIN`

Default: default
Description: Imaging domain/tenant used to fetch data in multi-tenant environments.

`CONTROL_PANEL_SSL_ENABLED`

Default: false
Description: Set to true when Control Panel config/eureka endpoints run on HTTPS.

`MCP_TOOL_SURFACE_PROFILE`

Default: full Description: Selects the MCP tool exposure profile. Use full to expose the complete toolset, or intents for the meta-tool surface.

`MCP_INTENTS_HIDDEN_FUNCTIONS`

Default: empty Description: Comma-separated list of structural functions to hide when MCP_TOOL_SURFACE_PROFILE is set to intents.

`SERVICE_HOST` (Required)

Default: None (user needs to provide the value)
Description: IP/hostname of the machine on which the MCP Server is running.

`SSL_CA_BUNDLE`

Default: empty
Description: Optional path to a PEM CA bundle for private/self-signed certificate chains. With the Docker installer, place the PEM under ./certificates/ and reference it as /app/certificates/<file>.pem.

VS Code + GitHub Copilot Setup

This section provides detailed steps for for connecting the CAST Imaging MCP Server with Github Copilot.

1) Install GitHub Copilot on your VS code

Open the Extensions view (Ctrl+Shift+X or Cmd+Shift+X).
Search for "GitHub Copilot" and click Install.
Sign in to GitHub when prompted

2) Generate CAST Imaging API Key

Login to your CAST Imaging
Navigate to your profile section.
Generate a new API key (copy and save this key securely as you'll need it in the next steps)

3) Create MCP configuration (`.vscode/mcp.json`)

Open any folder in VS Code and create a .vscode folder in its root. Inside that, create mcp.json file.

json

{
  "inputs": [
    {
      "id": "imaging-key",
      "type": "promptString",
      "description": "CAST Imaging API Key"
    },
    {
      "id": "imaging-tenant",
      "type": "promptString",
      "description": "Imaging tenant"
    }
  ],
  "servers": {
    "imaging": {
      "type": "http",
      "url": "http://<your-mcp-server-host:port>/mcp/",
      "headers": {
        "x-api-key": "${input:imaging-key}",
        "x-user-tenant": "${input:imaging-tenant}"
      }
    }
  }
}

4) (Alternative) Manual registration flow

If VS Code doesn’t auto‑pick the server:

Open Copilot Chat → gear icon → Select tools that are available to chat
+ Add More Tools… → + Add MCP Server… → choose HTTP
Enter http(s)://<your-mcp-server-host:port>/mcp/ and confirm
VS Code writes .vscode/copilot/mcp.json → add the header block:

json

"my-mcp-server-xxxx": {
  "url": "http://<your-mcp-server-host:port>/mcp/",
  "headers": {
    "x-api-key": "${input:imaging-key}",
    "x-user-tenant": "${input:imaging-tenant}"
  }
}

5) Project instructions for Copilot

Copy copilot-instructions.md from the installer into your VScode by creating a folder named .github and then pasting the copilot-instructions.md file inside it. This will help the agent in proving better responses.

Logs & Checks

bash

# Server logs
docker logs <mcp-container-id>

# Re‑verify Imaging‑APIs
curl -H "x-api-key: <your-key>"      http://{CONTROL_PANEL_HOST}:8090/imaging/apis/rest/ready

Security Notes

IMAGING_CODE = False by default: enabling allows MCP clients to access source code → restrict by policy, network, and credentials.
SSL_CA_BUNDLE for private CAs: prefer a CA bundle over disabling TLS verification.
Principle of least privilege: limit who can obtain/enter Imaging API keys in MCP hosts.
