Delulu - A suite of MCP tools to supercharge your LLM skillset

[!TIP] More knowing. Less guessing.

Delulu will provide a suite of tools to help your LLM search and crawl the Web and API to give you high-quality information.

The first tool released is a travel agent that can search on:

• Google Flights
• Google Hotels

Motivation

[!TIP] One chat UI to rule them all
One MCP to find them
One query to bring them all
And by the LLM bind them

1. Manual Download - Visit the GitHub Releases page and download the appropriate file for your platform and architecture, then extract the binary.

2. Run the MCP server:

   # HTTP transport (for remote clients)
   delulu-travel-mcp http --host 0.0.0.0 --port 8080
   
   # Or stdio transport (for Claude Desktop)
   delulu-travel-mcp stdio
   

🦀 Option 2: Cargo (Rust Users)

# Build from source
git clone https://github.com/mratsim/delulu
cd delulu
cargo build --release --features mcp

# Run the MCP server
./target/release/delulu-travel-mcp http --port 8080

🐳 Option 3: Docker or Podman

# HTTP transport (for remote clients)
docker run -p 8080:8080 \
  --env RUST_LOG=info \
  ghcr.io/mratsim/delulu/travel-agent:latest \
  http --host 0.0.0.0 --port 8080

# Stdio transport (for Claude Desktop) - requires interactive mode
docker run -i --rm ghcr.io/mratsim/delulu/travel-agent:latest stdio

🐳 Option 4: Docker-compose

git clone https://github.com/mratsim/delulu
cd delulu
docker-compose up -d

The docker-compose uses HTTP transport. Access the MCP server at http://localhost:8080/mcp.
