🐼 Panda

Your gateway to the ethpandaops ecosystem. It's a CLI, an MCP server, and a sandboxed Python runtime that talks to ClickHouse, Prometheus, Loki, and Ethereum nodes so you don't have to wrangle credentials or know each API individually.

Code runs on your machine. Credentials stay in the proxy. Sandbox containers never receive datasource credentials.

Getting Started

The server always runs locally on your machine. The two deployment modes differ only in where the credential proxy runs.

Prerequisites

• Docker with the Compose plugin
• A terminal

Install

curl -sSfL https://raw.githubusercontent.com/ethpandaops/panda/master/scripts/install.sh | sh

This installs the panda CLI to ~/.local/bin/.

Mode 1: Hosted Proxy (recommended)

Use the ethpandaops-hosted proxy at panda-proxy.ethpandaops.io. You get access to shared Xatu ClickHouse data, Prometheus, and Loki without managing any credentials.

# Set up everything: pull images, write config, authenticate, start server
panda init

# Verify
panda server status
panda datasources

panda init walks you through:

1. Checking Docker and pulling the server + sandbox images
2. Writing config files to ~/.config/panda/
3. Opening a browser for GitHub OAuth login against the hosted proxy
4. Starting the server container

Mode 2: Local Proxy (bring your own credentials)

Run your own proxy when you have direct access to datasource credentials (ClickHouse, Prometheus, Loki, etc.).

# 1. Initialize with your local proxy URL, skip hosted auth
panda init --proxy-url http://host.docker.internal:18081 --skip-auth

Note: The server runs inside a Docker container, so it cannot reach localhost on your host machine. Use host.docker.internal (macOS/Windows) or 172.17.0.1 (Linux) to point at a proxy running on your host.

# 2. Create a proxy config with your credentials
cat > proxy-config.yaml <<'EOF'
server:
  listen_addr: ":18081"
auth:
  mode: none
clickhouse:
  - name: my-cluster
    host: "clickhouse.example.com"
    port: 8443
    database: default
    username: "user"
    password: "pass"
    secure: true
EOF

# 3. Run the proxy (using the same Docker image)
docker run -d --name panda-proxy \
  -p 18081:18081 \
  -v $(pwd)/proxy-config.yaml:/config/proxy-config.yaml:ro \
  --entrypoint /app/panda-proxy \
  ethpandaops/panda:server-latest \
  --config /config/proxy-config.yaml

# 4. Verify
panda server status
panda datasources

See proxy-config.example.yaml for the full set of configurable datasources (Prometheus, Loki, Ethereum nodes, etc.).

Verify it works

panda datasources                          # List available datasources
panda execute --code 'print("hello")'      # Run Python in the sandbox

Client Setup

Claude Code — add to ~/.claude.json:

{
  "mcpServers": {
    "ethpandaops-panda": {
      "type": "http",
      "url": "http://localhost:2480/mcp"
    }
  }
}

Claude Desktop — add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "ethpandaops-panda": {
      "type": "http",
      "url": "http://localhost:2480/mcp"
    }
  }
}

Skills

Install agent skills for AI coding assistants:

npx skills add ethpandaops/panda              # all skills
npx skills add ethpandaops/panda --skill install-mcp    # register panda as an MCP server
npx skills add ethpandaops/panda --skill install-panda  # installation guide

Auth

The hosted proxy requires authentication via GitHub OAuth. If you used panda init with the default hosted proxy, auth is handled during setup. To re-authenticate or refresh:

panda auth login

Local proxies with auth.mode: none do not require authentication.

Server Management

panda server start      # Start the server container
panda server stop       # Stop the server container
panda server restart    # Restart the server container
panda server status     # Show container status and health
panda server logs       # Stream server logs
panda server update     # Pull latest images and restart

Development

cp config.example.yaml config.yaml
cp proxy-config.example.yaml proxy-config.yaml
make docker-sandbox
docker compose up -d

make build              # Build panda-server and panda
make build-proxy        # Build standalone proxy binary
make test               # Run tests with race detector
make lint               # Run golangci-lint
make docker             # Build server Docker image
make docker-sandbox     # Build sandbox image
make download-models    # Download embedding model for semantic search
