Portainer MCP

Go Report Card coverage

Ever wished you could just ask Portainer what's going on?

Now you can! Portainer MCP connects your AI assistant directly to your Portainer environments. Manage Portainer resources such as users and environments, or dive deeper by executing any Docker or Kubernetes command directly through the AI.

portainer-mcp-demo

Overview

Portainer MCP is a work in progress implementation of the Model Context Protocol (MCP) for Portainer environments. This project aims to provide a standardized way to connect Portainer's container management capabilities with AI models and other services.

MCP (Model Context Protocol) is an open protocol that standardizes how applications provide context to LLMs (Large Language Models). Similar to how USB-C provides a standardized way to connect devices to peripherals, MCP provides a standardized way to connect AI models to different data sources and tools.

This implementation focuses on exposing Portainer environment data through the MCP protocol, allowing AI assistants and other tools to interact with your containerized infrastructure in a secure and standardized way.

See the Portainer Version Support and Supported Capabilities sections for more details on compatibility and available features.

Note: This project is currently under development.

It is currently designed to work with a Portainer administrator API token.

Installation

You can download pre-built binaries for Linux (amd64) and macOS (arm64) from the Latest Release Page. Find the appropriate archive for your operating system and architecture under the "Assets" section.

Download the archive: You can usually download this directly from the release page. Alternatively, you can use curl. Here's an example for macOS (ARM64) version v0.2.0:

# Example for macOS (ARM64) - adjust version and architecture as needed
curl -Lo portainer-mcp-v0.2.0-darwin-arm64.tar.gz https://github.com/portainer/portainer-mcp/releases/download/v0.2.0/portainer-mcp-v0.2.0-darwin-arm64.tar.gz

(Linux AMD64 binaries are also available on the release page.)

(Optional but recommended) Verify the checksum: First, download the corresponding .md5 checksum file from the release page. Example for macOS (ARM64) v0.2.0:

# Download the checksum file (adjust version/arch)
curl -Lo portainer-mcp-v0.2.0-darwin-arm64.tar.gz.md5 https://github.com/portainer/portainer-mcp/releases/download/v0.2.0/portainer-mcp-v0.2.0-darwin-arm64.tar.gz.md5
# Now verify (output should match the content of the .md5 file)
if [ "$(md5 -q portainer-mcp-v0.2.0-darwin-arm64.tar.gz)" = "$(cat portainer-mcp-v0.2.0-darwin-arm64.tar.gz.md5)" ]; then echo "OK"; else echo "FAILED"; fi

(For Linux, you can use md5sum -c <checksum_file_name>.md5) If the verification command outputs "OK", the file is intact.

Extract the archive:

# Adjust the filename based on the downloaded version/OS/architecture
tar -xzf portainer-mcp-v0.2.0-darwin-arm64.tar.gz

This will extract the portainer-mcp executable.

Move the executable: Move the executable to a location in your $PATH (e.g., /usr/local/bin) or note its location for the configuration step below.

Usage

With Claude Desktop, configure it like so:

{
    "mcpServers": {
        "portainer": {
            "command": "/path/to/portainer-mcp",
            "args": [
                "-server",
                "[IP]:[PORT]",
                "-token",
                "[TOKEN]",
                "-tools",
                "/tmp/tools.yaml"
            ]
        }
    }
}

Replace [IP], [PORT] and [TOKEN] with the IP, port and API access token associated with your Portainer instance.

Note

By default, the tool looks for "tools.yaml" in the same directory as the binary. If the file does not exist, it will be created there with the default tool definitions. You may need to modify this path as described above, particularly when using AI assistants like Claude that have restricted write permissions to the working directory.

Tool Customization

By default, the tool definitions are embedded in the binary. The application will create a tools file at the default location if one doesn't already exist.

You can customize the tool definitions by specifying a custom tools file path using the -tools flag:

{
    "mcpServers": {
        "portainer": {
            "command": "/path/to/portainer-mcp",
            "args": [
                "-server",
                "[IP]:[PORT]",
                "-token",
                "[TOKEN]",
                "-tools",
                "/path/to/custom/tools.yaml"
            ]
        }
    }
}

The default tools file is available for reference at internal/tooldef/tools.yaml in the source code. You can modify the descriptions of the tools and their parameters to alter how AI models interpret and decide to use them. You can even decide to remove some tools if you don't wish to use them.

Warning

Do not change the tool names or parameter definitions (other than descriptions), as this will prevent the tools from being properly registered and functioning correctly.

Read-Only Mode

For security-conscious users, the application can be run in read-only mode. This mode ensures that only read operations are available, completely preventing any modifications to your Portainer resources.

To enable read-only mode, add the -read-only flag to your command arguments:

{
    "mcpServers": {
        "portainer": {
            "command": "/path/to/portainer-mcp",
            "args": [
                "-server",
                "[IP]:[PORT]",
                "-token",
                "[TOKEN]",
                "-read-only"
            ]
        }
    }
}

When using read-only mode:

  • Only read tools (list, get) will be available to the AI model
  • All write tools (create, update, delete) are not loaded
  • The Docker proxy requests tool is not loaded
  • The Kubernetes proxy requests tool is not loaded

Code Statistics

The repository includes a helper script cloc.sh to calculate lines of code and other metrics for the Go source files using the cloc tool. You might need to install cloc first (e.g., sudo apt install cloc or brew install cloc).

Run the script from the repository root to see the default summary output:

./cloc.sh

Refer to the comment header within the cloc.sh script for details on available flags to retrieve specific metrics.
