✨ What You Get

• Container workflow tools for Docker or Podman
• IBM Container Registry (ICR) tools — list namespaces, list images, delete images
• IBM Code Engine project and application management tools
• MCP-ready setup for GitHub Copilot, Cline, Claude Desktop, and the optional VS Code extension in vscode-extension/
• A simple local development and troubleshooting workflow

🚀 Quick Start

# 1) Install dependencies
npm install

# 2) Build the server
npm run build

# 3) Run once to verify
node build/index.js

Then configure your MCP client using one of the examples in the Configuration section below.

🤖 The Agentic Experience (No Docker/Code Engine Lingo Needed)

The true power of this MCP server is that you don't need to know Docker or Code Engine commands. You can simply state your goal, and the LLM will discover the environment, run the pipeline, and fix issues autonomously.

Here is an example interaction from a real session:

User:

"I have an app in the developer-splash folder. Deploy it to my Code Engine project."

Assistant's Autonomous Thought Process:

1. Discovery: "Let me check what projects and namespaces exist... Found project markus-app-v2-toronto and namespace mvk-code-engine."
2. Prerequisites: "No pull secret in this project yet. I'll get the API key from the .env file and create the secret icr-pull-secret."
3. Execution: "Now I'll run the full pipeline: build → push → deploy → wait."
4. Validation: "It's deployed but stuck at 'deploying'. Let me check the logs... The container is running but the readiness probe is failing."
5. Self-Correction: "Ah, the sed pattern in the Dockerfile didn't match nginx alpine's default config format for port 80. I'll fix the Dockerfile with a regex-safe sed and rebuild."
6. Completion: "App is live! 🎉 Status: ready."

Assistant Response to User:

"Your app is deployed and live at: https://developer-splash.29m5mrru3s3n.ca-tor.codeengine.appdomain.cloud. I had to fix a minor port configuration issue in your Dockerfile, but it is successfully running now!"

With this MCP server, the AI acts as an expert DevOps engineer pairing with you.

Deploy Your First App

This walks through deploying the included Star Wars splash page example — a static nginx container — entirely through the MCP server.

Apple Silicon users: always build with --platform linux/amd64. Code Engine runs amd64 only.

Step 1 — Build and push the image

cd examples/starwars-splash
podman build --platform linux/amd64 -t us.icr.io/<your-namespace>/starwars-splash:v1.0.0 .
podman push us.icr.io/<your-namespace>/starwars-splash:v1.0.0

Or ask your assistant:

Build examples/starwars-splash as us.icr.io/my-namespace/starwars-splash:v1.0.0 for linux/amd64 and push it

MCP response — build_container_image:

{
  "success": true,
  "command": "podman build --platform linux/amd64 -t us.icr.io/my-namespace/starwars-splash:v1.0.0 ...",
  "build_output": "STEP 1/5: FROM nginx:alpine\nSTEP 2/5: COPY index.html /usr/share/nginx/html/index.html\nSTEP 3/5: RUN sed -i 's/listen  80;/listen 8080;/g' /etc/nginx/conf.d/default.conf\nSTEP 4/5: EXPOSE 8080\nSTEP 5/5: CMD [\"nginx\", \"-g\", \"daemon off;\"]\nSuccessfully tagged us.icr.io/my-namespace/starwars-splash:v1.0.0"
}

Note: Container runtimes (Podman/Docker) write build progress to stderr. The build_output field combines stdout and stderr so you see the full build log.

MCP response — push_container_image:

{
  "success": true,
  "command": "podman push us.icr.io/my-namespace/starwars-splash:v1.0.0",
  "output": "Getting image source signatures\nCopying blobs...\nWriting manifest to image destination"
}

Step 2 — Create a registry pull secret

Ask your assistant (once per project):

Create a registry secret called icr-pull-secret in project <project-id> for us.icr.io using my IBM Cloud API key

Or use the ce_create_secret tool directly:

{
  "project_id": "<your-project-id>",
  "name": "icr-pull-secret",
  "format": "registry",
  "data": {
    "username": "iamapikey",
    "password": "<your-ibm-cloud-api-key>",
    "server": "us.icr.io",
    "email": "user@example.com"
  }
}

MCP response — ce_create_secret:

{
  "name": "icr-pull-secret",
  "format": "registry",
  "resource_type": "secret_registry_v2",
  "created_at": "2026-05-08T22:10:00Z",
  "project_id": "<your-project-id>"
}

Step 3 — Deploy the application

Ask your assistant:

Deploy us.icr.io/my-namespace/starwars-splash:v1.0.0 to Code Engine project <project-id>
as app "starwars-splash" using pull secret icr-pull-secret, min 1 instance

Or use the ce_create_application tool:

{
  "project_id": "<your-project-id>",
  "name": "starwars-splash",
  "image": "us.icr.io/<your-namespace>/starwars-splash:v1.0.0",
  "image_secret": "icr-pull-secret",
  "scale_min_instances": 1,
  "scale_max_instances": 3
}

MCP response — ce_create_application:

{
  "name": "starwars-splash",
  "resource_type": "app_v2",
  "status": "deploying",
  "image_reference": "us.icr.io/my-namespace/starwars-splash:v1.0.0",
  "image_secret": "icr-pull-secret",
  "image_port": 8080,
  "scale_min_instances": 1,
  "scale_max_instances": 3,
  "scale_cpu_limit": "1",
  "scale_memory_limit": "4G",
  "endpoint": "https://starwars-splash.<subdomain>.us-south.codeengine.appdomain.cloud",
  "status_details": {
    "latest_created_revision": "starwars-splash-00001",
    "latest_ready_revision": null
  }
}

Step 4 — Check deployment status

Get details for the starwars-splash app in project <project-id>

This calls ce_get_application and returns the public URL once the app reaches ready status.

List the running instances of starwars-splash in project <project-id>

This calls ce_list_app_instances (or ce_get_app_instance for a specific instance) and shows:

• Instance name and revision
• Container status (running / pending / failed)
• Restart count
• Started-at timestamp
• CPU and memory allocation

MCP response — ce_get_application (once ready):

{
  "name": "starwars-splash",
  "status": "ready",
  "image_reference": "us.icr.io/my-namespace/starwars-splash:v1.0.0",
  "image_port": 8080,
  "scale_min_instances": 1,
  "scale_max_instances": 3,
  "scale_cpu_limit": "0.5",
  "scale_memory_limit": "1G",
  "region": "us-south",
  "endpoint": "https://starwars-splash.<subdomain>.us-south.codeengine.appdomain.cloud",
  "status_details": {
    "latest_created_revision": "starwars-splash-00001",
    "latest_ready_revision": "starwars-splash-00001"
  }
}

Step 5 — Map a custom domain (optional)

To serve the app at your own domain (e.g. myapp.example.com) you need a TLS certificate. The IBM Code Engine REST API always requires a real certificate — IBM's Console "Platform managed" option is not available via the API.

5a — Get a Let's Encrypt certificate (certbot)

# Install once
brew install certbot

# Request cert — certbot will print a DNS TXT challenge value
mkdir -p ~/certbot/{config,work,logs}
/opt/homebrew/bin/certbot certonly --manual --preferred-challenges dns \
  -d <your-domain> --agree-tos --no-eff-email --email you@example.com \
  --config-dir ~/certbot/config --work-dir ~/certbot/work --logs-dir ~/certbot/logs

Certbot will pause and ask you to add a TXT record:

Add TXT record: _acme-challenge.<your-domain> = <challenge-value>

Verify propagation, then press Enter. Certbot writes:

• ~/certbot/config/live/<your-domain>/fullchain.pem
• ~/certbot/config/live/<your-domain>/privkey.pem

5b — Create the TLS secret in Code Engine

Ask your assistant:

Create a TLS secret called starwars-tls in project <project-id>
using cert ~/certbot/config/live/myapp.example.com/fullchain.pem
and key ~/certbot/config/live/myapp.example.com/privkey.pem

This calls ce_create_tls_secret_from_pem — reads the PEM files from disk and stores them as a Code Engine tls secret.

MCP response — ce_create_tls_secret_from_pem:

{
  "name": "my-tls",
  "format": "tls",
  "resource_type": "secret_tls_v2",
  "created_at": "2026-05-08T22:30:00Z",
  "project_id": "<your-project-id>"
}

5c — Create the domain mapping

Ask your assistant:

Map domain myapp.example.com to app my-app
in project <project-id> using TLS secret my-tls

This calls ce_create_domain_mapping and returns the cname_target.

MCP response — ce_create_domain_mapping:

{
  "name": "myapp.example.com",
  "status": "ready",
  "cname_target": "custom.<subdomain>.us-south.codeengine.appdomain.cloud",
  "component": {
    "resource_type": "app_v2",
    "name": "my-app"
  },
  "tls_secret": "my-tls",
  "region": "us-south"
}

5d — Update your CNAME

In your DNS provider, set:

myapp.example.com CNAME custom.<subdomain>.us-south.codeengine.appdomain.cloud

Use the cname_target value returned in 5c (it uses the custom. prefix, not the app name).

Once DNS propagates, https://<your-domain> serves the app with a valid TLS certificate.

Certificate renewal: Let's Encrypt certs expire after 90 days. Re-run certbot to get updated PEM files, then ask Copilot to run ce_renew_tls_secret_from_pem — it patches the existing secret in-place so your domain mapping continues working without any changes.

Full one-shot prompt

I have a Star Wars splash page in examples/starwars-splash.
Build it for linux/amd64 as us.icr.io/my-namespace/starwars-splash:v1.0.0,
push it, then deploy it to Code Engine project <project-id> with pull secret icr-pull-secret.
Tell me the public URL and confirm the instance is running.

🌐 Host Any MCP Server on Code Engine

You can use this MCP server to deploy another MCP server to Code Engine — no CLI, no Dockerfile, no YAML. The key ingredient is supergateway: a tiny bridge that wraps any STDIO-based MCP server as an HTTP + SSE endpoint, making it accessible to any remote client.

                         (Claude Desktop, Cursor, VS Code, …)

Any STDIO MCP server becomes a remotely accessible, auto-scaling cloud service — with no custom infrastructure.

This example deploys @tokenizin/mcp-npx-fetch, an MCP server that lets an AI assistant fetch content from public URLs.

The example files live in examples/mcp-server-supergateway/.

Step 1 — Deploy the hosted MCP server

Ask your assistant:

Deploy a hosted MCP fetch server to my Code Engine project <project-id>.
Use image docker.io/supercorp/supergateway on port 8000.
Startup args: --stdio "npx -y @tokenizin/mcp-npx-fetch" --outputTransport sse
Name it "mcp-fetch-server". No pull secret needed.

This calls ce_create_application:

{
  "project_id": "<your-project-id>",
  "name": "mcp-fetch-server",
  "image": "docker.io/supercorp/supergateway",
  "port": 8000,
  "run_args": ["--stdio", "npx -y @tokenizin/mcp-npx-fetch", "--outputTransport", "sse"]
}

MCP response — ce_create_application:

{
  "name": "mcp-fetch-server",
  "resource_type": "app_v2",
  "status": "deploying",
  "image_reference": "docker.io/supercorp/supergateway",
  "image_port": 8000,
  "scale_min_instances": 0,
  "scale_max_instances": 10,
  "endpoint": "https://mcp-fetch-server.<subdomain>.<region>.codeengine.appdomain.cloud",
  "status_details": {
    "latest_created_revision": "mcp-fetch-server-00001",
    "latest_ready_revision": null
  }
}

No pull secret is needed — docker.io/supercorp/supergateway is a public image. Code Engine scales to zero when idle; you pay only for actual requests.

Step 2 — Wait for the app to be ready

Ask your assistant:

Wait for mcp-fetch-server in project <project-id> to be ready

This calls ce_wait_for_app_ready:

{
  "project_id": "<your-project-id>",
  "app_name": "mcp-fetch-server",
  "timeout_seconds": 120
}

MCP response — ce_wait_for_app_ready:

{
  "app_name": "mcp-fetch-server",
  "status": "ready",
  "endpoint": "https://mcp-fetch-server.<subdomain>.<region>.codeengine.appdomain.cloud",
  "elapsed_seconds": 34,
  "poll_history": [
    { "attempt": 1, "status": "deploying", "elapsed_seconds": 10 },
    { "attempt": 2, "status": "deploying", "elapsed_seconds": 20 },
    { "attempt": 3, "status": "ready",     "elapsed_seconds": 34 }
  ]
}

Step 3 — Verify the running instance

Ask your assistant:

List the running instances of mcp-fetch-server in project <project-id>

This calls ce_list_app_instances:

MCP response — ce_list_app_instances:

{
  "instances": [
    {
      "name": "mcp-fetch-server-00001-deployment-abc123",
      "revision": "mcp-fetch-server-00001",
      "status": "running",
      "restart_count": 0,
      "started_at": "2026-05-09T12:01:44Z"
    }
  ]
}

Step 4 — Connect your MCP client

Use mcp-remote to bridge the HTTP+SSE endpoint back to STDIO for local clients.

VS Code mcp.json:

{
  "servers": {
    "fetch": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://mcp-fetch-server.<subdomain>.<region>.codeengine.appdomain.cloud/sse"
      ]
    }
  }
}

Claude Desktop claude_desktop_config.json:

{
  "mcpServers": {
    "fetch": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://mcp-fetch-server.<subdomain>.<region>.codeengine.appdomain.cloud/sse"
      ]
    }
  }
}

Step 5 — Test the endpoint

Verify the server is live and streaming:

curl -N https://mcp-fetch-server.<subdomain>.<region>.codeengine.appdomain.cloud/sse

Or open it in the MCP Inspector:

npx @modelcontextprotocol/inspector
# Connect via SSE → paste the Code Engine URL

Once connected, you will see the fetch tool listed and can invoke it directly from the inspector.

Full one-shot prompt

Deploy a hosted MCP fetch server to my Code Engine project <project-id>.
Use image docker.io/supercorp/supergateway on port 8000 with no pull secret.
run_args: --stdio "npx -y @tokenizin/mcp-npx-fetch" --outputTransport sse
Name it "mcp-fetch-server", wait for it to be ready, and give me the /sse URL
so I can add it to my mcp.json.

See examples/mcp-server-supergateway/ for the ready-to-use client config file.

Deploy any other STDIO MCP server

The same pattern works for any npx-runnable MCP server — just swap the --stdio argument:

MCP Server	--stdio argument
Fetch	npx -y @tokenizin/mcp-npx-fetch
Filesystem	npx -y @modelcontextprotocol/server-filesystem /data
Brave Search	npx -y @modelcontextprotocol/server-brave-search
Your own server	node /app/server.js

⚙️ Configuration

VS Code — IBM Code Engine MCP extension (optional)

The extension in vscode-extension/ registers this MCP server with VS Code using the MCP server definition provider API (VS Code 1.101+). You do not need a workspace .vscode/mcp.json entry for the default flow: the server is started with npx -y code-engine-mcp-server and your API key from settings.

1. Install the extension (from a .vsix built with npm run package inside vscode-extension/, or from the Marketplace when published).
2. Ensure Node.js is installed and npx is on your PATH.
3. Open Settings and search for IBM Code Engine MCP, or edit settings.json directly:
   • codeEngineMcp.apiKey — your IBM Cloud API key (required; until this is set, the extension contributes no MCP server).
   • codeEngineMcp.region — IBM Cloud region (optional, default us-south). Passed as IBMCLOUD_REGION to the server.

The extension sets IBMCLOUD_API_KEY and IBMCLOUD_REGION for the spawned process. Use GitHub Copilot and MCP in VS Code as described in the Copilot documentation.

More detail: vscode-extension/README.md.

---

1) GitHub Copilot (VS Code) — mcp.json (workspace)

Copy mcp.example.json to .vscode/mcp.json in your workspace root:

cp mcp.example.json ../.vscode/mcp.json

Then edit .vscode/mcp.json and replace the placeholder with your IBM Cloud API key:

{
    "servers": {
        "code-engine": {
            "type": "stdio",
            "command": "node",
            "args": [
                "${workspaceFolder}/code-engine-mcp-server/build/index.js"
            ],
            "env": {
                "IBMCLOUD_API_KEY": "your-ibm-cloud-api-key-here"
            }
        }
    }
}

Restart the server: Cmd+Shift+P -> "MCP: Restart Server" -> code-engine.

Security: Add .vscode/mcp.json to your .gitignore to avoid committing your API key.

Get your API key at IBM Cloud IAM → API keys.

2) Cline (VS Code Extension)

1. Open VSCode Settings (Cmd/Ctrl + ,)
2. Search for "Cline: MCP Settings"
3. Click "Edit in settings.json"
4. Add the configuration:

{
  "cline.mcpServers": {
    "code-engine": {
      "command": "node",
      "args": ["/absolute/path/to/code-engine-mcp-server/build/index.js"],
      "env": {
        "IBMCLOUD_API_KEY": "your-api-key-here"
      }
    }
  }
}

3) Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "code-engine": {
      "command": "node",
      "args": ["/absolute/path/to/code-engine-mcp-server/build/index.js"],
      "env": {
        "IBMCLOUD_API_KEY": "your-api-key-here"
      }
    }
  }
}

2. Test it locally on port 3000
3. Push it to icr.io/my-namespace/myapp:v1.0.0
4. Deploy it to my Code Engine project "production"
5. Show me the application URL

Custom Domain

Ask your assistant:

Create a TLS secret called my-tls in project <project-id>
using cert ~/certbot/config/live/example.com/fullchain.pem
and key ~/certbot/config/live/example.com/privkey.pem.
Then map domain example.com to app my-app using that secret.
Tell me what CNAME value to set in DNS.

🔐 Environment Variables

• IBMCLOUD_API_KEY: IBM Cloud API key (required for Code Engine operations)
• IBMCLOUD_REGION: Default IBM Cloud region (optional, defaults to us-south)
• CONTAINER_RUNTIME: Force specific runtime (docker or podman)
• DEBUG: Enable debug logging

📋 Prerequisites

• Node.js v18 or higher
• Docker or Podman installed (for container build/push tools)
• IBM Cloud API key (for all Code Engine and ICR operations)

The MCP server communicates directly with the IBM Cloud REST API and ICR API. No IBM Cloud CLI or Code Engine plugin is required.

👩‍💻 Development

# Run in development mode
npm run dev

# Build
npm run build

# Test manually
node build/index.js

🧪 Troubleshooting

Server Not Connecting

1. Verify the path in configuration is absolute
2. Check Node.js is in PATH: node --version
3. Verify build output exists: ls build/index.js
4. Test manually: node build/index.js

Docker/Podman Commands Failing

1. Verify installation: docker --version or podman --version
2. Check Docker daemon is running
3. Verify permissions (add user to docker group if needed)

Code Engine Commands Failing

1. Verify your API key is set: check IBMCLOUD_API_KEY in your MCP client config
2. Confirm the region is correct (default us-south); set IBMCLOUD_REGION if needed
3. Verify the project ID is valid: use ce_list_projects to find it
4. Check for expired tokens — the server re-fetches IAM tokens automatically; if errors persist, regenerate your API key at IBM Cloud IAM → API keys

🛡️ Security

• Never commit API keys to version control
• Use environment variables for sensitive data
• Consider using IBM Cloud IAM for authentication
• Restrict MCP server permissions as needed
