PlugLayer MCP server — deploy and manage infrastructure via AI

PlugLayer MCP Server

Deploy and manage your infrastructure through natural language with any MCP-compatible AI assistant.

Installation

Option 1: uvx (recommended — no install needed)

PLUGLAYER_API_KEY=your-pluglayer-api-token uvx pluglayer-mcp

This local command mode uses the MCP stdio transport by default, which is the right mode for Cursor, Claude Code, and other editor-launched command servers. The pluglayer-mcp command now always uses stdio so editor clients cannot accidentally switch it into HTTP mode.

Option 2: pip

pip install pluglayer-mcp
PLUGLAYER_API_KEY=your-pluglayer-api-token pluglayer-mcp

Configuration

Claude Desktop

Add to ~/.config/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "pluglayer": {
      "command": "uvx",
      "type": "stdio",
      "args": ["pluglayer-mcp"],
      "env": {
        "PLUGLAYER_API_KEY": "your-pluglayer-api-token"
      }
    }
  }
}

Cursor

Add to ~/.cursor/mcp.json:

{
  "pluglayer": {
    "command": "uvx",
    "type": "stdio",
    "args": ["pluglayer-mcp"],
    "env": {
      "PLUGLAYER_API_KEY": "your-pluglayer-api-token"
    }
  }
}

Remote HTTP (hosted)

The remote MCP server runs at mcp.pluglayer.com. Pass your token as:

Authorization: Bearer your-pluglayer-api-token

If you intentionally want to run the package itself as an HTTP MCP server, use:

pluglayer-mcp-http

Release Checklist

Before publishing a new pluglayer-mcp build:

1. Confirm local command mode still uses stdio by default.
2. Confirm PLUGLAYER_API_URL override works when pointed at a dev API.
3. Confirm package version will be unique for the publish run.
4. Publish from the public repo main branch after reviewing the dev -> main PR.

After publishing:

1. Restart Cursor, Claude Code, or the MCP client you are testing.
2. If the editor still behaves like an older MCP build, remove and re-add the MCP server entry, then restart the editor.
3. Re-test with a simple command such as:
   • get_current_user
   • list_projects
   • get_compute_summary

Cursor Notes

• For command-based MCP setup, use uvx pluglayer-mcp.
• Do not force HTTP transport for local editor usage.
• pluglayer-mcp always uses stdio, which is the correct transport for Cursor-launched command servers.
• Only use pluglayer-mcp-http when you intentionally want to run the package itself as an HTTP MCP server.

Available Tools

The MCP calls the PlugLayer FastAPI backend instead of re-implementing backend business logic. Auth, roles, ownership, compute guards, and k3s orchestration remain in the backend. MCP and editor plugins should authenticate with a PlugLayer API token created in the PlugLayer Settings page, not the browser/session auth token.

Managed registries are configured by PlugLayer admins in the platform UI/API. When deploy_image uses mirroring, the backend picks a registry the current user is allowed to use and keeps Kubernetes pull secrets in sync automatically.

Databases are a first-class Data Layer workflow in MCP. When a user needs a new database, wants to know whether one already exists, asks for a connection string, or needs env vars to wire an app to a database, the preferred MCP path is:

1. list_user_databases
2. if needed, list_database_templates
3. check_slug_availability
4. optionally check_database_slug_availability
5. create_database
   • the MCP tool resolves required deploy-time database env vars itself
   • password/secret/token/key fields are generated there when the template expects a random value
   • database-name placeholders are filled from the chosen app name
6. get_task_status
7. get_database_connection_details
8. optionally get_database_logs when troubleshooting
9. use update_database_access, restart_database, or remove_database for follow-up lifecycle actions

After provisioning a database, the assistant should proactively suggest exact env var updates for dependent apps instead of leaving the user with only a raw connection string.

Marketplace template deployment through MCP now supports both:

1. deploying into an existing project by project_id
2. creating a new project inline by passing project_name

list_nodes	List accessible compute nodes
list_registries	List the registries currently available to the user

Example Conversations

Deploy your first app:

"I have a FastAPI app at ghcr.io/myorg/api:latest that runs on port 8000. Deploy it into my production project in my cloud."

Convert docker-compose:

"Here's my docker-compose.yml: [paste]. Deploy this to PlugLayer."

CI/CD setup:

"Generate a GitHub Actions workflow for my api deployment so it auto-deploys on push to main."

Add a custom domain:

"Add api.example.com to my production project, detect the provider, show me the DNS records in a table, then verify it and attach it to my API app."

Provision a database and wire the backend to it:

"Create a Postgres database in my marketplace project, check whether the slug postgres is available first, and after it finishes show me the connection env vars so we can update my backend."

Reuse an existing database instead of creating a new one:

"Check whether I already have a Mongo or Postgres database in my project. If I do, show me the connection details and suggest the backend env vars I should update."

Getting Your API Key

1. Go to PlugLayer Settings
2. Create a PlugLayer API token
3. Copy it once and store it safely
4. Use it as PLUGLAYER_API_KEY for MCP, editor plugins, and CI/CD webhook deploys
