Daydream

[!CAUTION] PACKAGE DEPRECATED This package has been renamed to unpage. Please use unpage instead:

pip install unpage

See the unpage repository for the latest version.

[!WARNING] ALPHA SOFTWARE Daydream is experimental, under heavy development, and may be unstable. Use at your own risk!

Daydream is an infrastructure knowledge graph builder, and an MCP server to enable your LLM-powered application to understand and query your infrastructure.

Installation

[!CAUTION] USE unpage INSTEAD This package is deprecated. Install unpage instead:

pip install unpage

Prerequisites (Legacy - for reference only)

• Python 3.12 or higher
• uv package manager

Install uv

On macOS:

brew install uv

For other platforms, follow the official uv installation guide.

Install Daydream (DEPRECATED)

Daydream is designed to be run using uvx, which comes with uv:

uvx daydream

That will automatically install daydream from PyPI in a virtualenv and then run it!

Setup Daydream

uvx daydream configure

Usage

Building the Graph

Before using Daydream, build your knowledge graph:

uvx daydream build-graph

To use a specific profile:

uvx daydream build-graph --profile your-graph-name
# Or set DAYDREAM_PROFILE=your-graph-name

Configure your client to use the MCP Server

Claude Desktop

On macOS:

uvx daydream configure

That will, among many other things, create or update the ~/Library/Application Support/Claude/claude_desktop_config.json file.

How Daydream Works

Daydream builds a knowledge graph of your infrastructure using a fairly simple inference strategy:

1. Daydream queries the APIs of your integrated tools and retrieves all supported resources, and adds each one as a node in the knowledge graph.
2. Daydream extracts unique identifiers and aliases for each retrieved resource, and adds them to a mapping.
3. Daydream extracts potential references from each retrieved resource, and attempts to match them to identifiers and aliases in the mapping to create edges between nodes.

Once the graph is built, the MCP server provides a set of tools for traversing the graph and interacting with nodes.

Configuration

Authentication

Daydream uses your local credentials to access various platforms and tools. Make sure you have the necessary credentials configured:

1. AWS Credentials: Configure using standard AWS credential methods (profiles, aws configure CLI, EC2 )
2. Aptible Credentials: Run aptible login to set up your Aptible credentials
3. Datadog Credentials: Add your Datadog API key and application key to your config.yaml (see below)

config.yaml

Daydream can be configured using a config.yaml file in the ~/.daydream folder:

# Default configuration file location: ~/.daydream/profiles/default/config.yaml
plugins:
  aptible:
    enabled: true
  aws:
    enabled: true
    # These are optional settings for AWS that enable you to specify an existing AWS profile on your system
    # Daydream will use the credentials from that AWS profile to build the infrastructure graph and
    # access CloudWatch metrics about resourse in the MCP server.
    settings:
      accounts:
        dev-account:
          profile: dev-engineering-readonly
  core:
    enabled: true
  datadog:
    enabled: true
    settings:
      api_key: <your datadog API key>
      application_key: <your datadog application key>
  graph:
    enabled: true
  logs:
    enabled: false
  metrics:
    enabled: true
  networking:
    enabled: true

Plugins

Daydream supports various plugins to integrate with different platforms:

AWS Plugin

• Supports querying AWS resources across multiple regions
• Uses standard AWS credential resolution and profiles in config.yaml
• Supported resources: EC2, RDS, ALBs, ELBs, target groups
• Infers knowledge graph edges between services like ALBs, target groups, and EC2 instances

Aptible Plugin

• Integrates with Aptible platform
• Uses credentials from ~/.aptible/tokens.json, which is created by aptible login
• Supports apps, databases, and environments
• Infers knowledge graph edges between Aptible and AWS resources

Datadog Plugin

• Integrates with your Datadog organization
• Uses the API key and application key configured in your config.yaml
• Supports importing your Datadog teams, services, systems, and other entities from your software catalog into your knowledge graph

Adding New Plugins

Plugins are managed in the src/daydream/plugins folder. The Aptible and AWS plugins are good examples for adding new resources to the graph and querying metrics.

Client Setup

We recommend using uvx daydream configure to configure clients like Claude Desktop or Amazon Q. This section has examples of configuring those manually...

Claude Desktop

1. Create or edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
    "mcpServers": {
        "daydream": {
            "command": "/opt/homebrew/bin/uvx",
            "args": ["daydream", "start"],
            "env": {
                "HOME": "/Users/YOUR_USER"
            }
        }
    }
}

Amazon Q

1. Create or edit ~/.aws/amazonq/mcp.json:

{
    "mcpServers": {
        "daydream": {
            "command": "/opt/homebrew/bin/uvx",
            "args": ["daydream", "start"],
            "env": {
                "HOME": "/Users/YOUR_USER"
            }
        }
    }
}

AWS Vault Integration

If you prefer to use aws-vault (or another similar tool) instead of daydream's configuration directly, you can use a configuration like this:

{
    "mcpServers": {
        "daydream": {
            "command": "aws-vault",
            "args": ["exec", "YOUR_AWS_PROFILE", "--", "/opt/homebrew/bin/uvx", "daydream", "start", "--disable-sse"]
        }
    }
}
