Project description

Portainer MCP Server

Portainer MCP Server

License: MIT Python 3.10+ MCP PyPI

An MCP (Model Context Protocol) server that gives AI assistants — Claude, Copilot, Cursor, and others — 23 tools to manage Portainer container environments: deploy and update stacks, start/stop/restart containers, pull/remove images, inspect endpoints, and manage users — all through natural language.

For LLM agents: This server connects via stdio transport. Every tool returns JSON. All mutating operations are audit-logged. Credentials are passed via environment variables, never hardcoded.


Why Use This

  • Natural language DevOps — Ask your AI assistant to deploy a stack, check container logs, or pull an image.
  • Swarm-aware — Automatically detects Docker Swarm clusters and uses the correct API.
  • Safe by default — Input validation, path traversal protection, sensitive field filtering, and force-remove disabled by default.
  • Works everywhere — Claude Desktop, Claude Code, Cursor, Windsurf, VS Code, Continue.dev.

1. Install

pip install portainer-mcp

Tools

All 23 tools are listed below with their parameters and descriptions. Every tool returns JSON.

Authentication

Tool Description
portainer_status() Check connection and authentication status. Returns version and instance ID.

Endpoints (Environments)

Tool Description
portainer_endpoints_list() List all environments. Returns id, name, type, url, status.
portainer_endpoint_inspect(endpoint_id) Get endpoint details (sensitive fields like TLS certs are filtered).

Stacks

Tool Description
portainer_stacks_list() List all stacks with id, name, type, status, endpoint_id.
portainer_stack_inspect(stack_id) Get stack details including the docker-compose file content.
portainer_stack_deploy(name, compose_content, endpoint_id?) Deploy a new stack. Auto-detects Swarm vs standalone.
portainer_stack_update(stack_id, compose_content?, endpoint_id?) Update a stack. Omit compose_content to redeploy existing.
portainer_stack_delete(stack_id) Delete a stack.
portainer_stack_start(stack_id) Start a stopped stack.
portainer_stack_stop(stack_id) Stop a running stack.

Containers

Tool Description
portainer_containers_list(endpoint_id?, all?) List containers. Set all=true to include stopped.
portainer_container_inspect(container_id, endpoint_id?) Get detailed container info.
portainer_container_start(container_id, endpoint_id?) Start a stopped container.
portainer_container_stop(container_id, endpoint_id?) Stop a running container.
portainer_container_restart(container_id, endpoint_id?) Restart a container.
portainer_container_remove(container_id, force?, endpoint_id?) Remove a container. force defaults to false.
portainer_container_logs(container_id, tail?, endpoint_id?) Get container logs. tail defaults to 100 (max 1000).

Images

Tool Description
portainer_images_list(endpoint_id?) List images with tags and sizes.
portainer_image_inspect(image_id, endpoint_id?) Get detailed image info.
portainer_image_pull(image_name, tag?, endpoint_id?) Pull an image. tag defaults to "latest".
portainer_image_remove(image_id, endpoint_id?) Remove an image.

Users

Tool Description
portainer_users_list() List all Portainer users with id, username, role.
portainer_user_inspect(user_id) Get user details.

Example Workflows

Deploy a new service:

"Deploy a stack called 'redis' with Redis 7 on port 6379"

The agent will call portainer_stack_deploy(name="redis", compose_content="...") with the generated compose YAML.

Debug a failing container:

"Why is the nginx container crashing?"

The agent will call portainer_containers_list() to find the container, then portainer_container_logs(container_id) to inspect the logs.

Update an existing stack:

"Update the arena-etl stack to use the new image tag v2.1"

The agent will call portainer_stack_inspect(stack_id) to get the current compose file, modify the image tag, then portainer_stack_update(stack_id, compose_content).


Security

  • JWT auth with proactive refresh (7h TTL, Portainer default is 8h) plus 401-retry fallback.
  • SSL verification enabled by default. Only disable for self-signed certificates.
  • Input validation — container IDs, image references, and stack names are validated with regex before API calls. Path traversal (..) is blocked.
  • Sensitive field filteringendpoint_inspect strips TLS certificates, Azure credentials, and security settings from responses.
  • Audit logging — all mutating operations (deploy, delete, remove, pull, start, stop) are logged to stderr with parameters.
  • No hardcoded credentials — all secrets come from environment variables.
  • Container removalforce defaults to false to prevent accidental deletion of running containers.
  • Log size limits — container logs are capped at 100K characters to prevent memory exhaustion.

Development

git clone https://github.com/ginkida/portainer-mcp.git
