⁠Deploy

⁠Docker Compose (recommended)

docker-compose up -d

⁠Docker Run (stdio mode)

docker run -i --rm hackerdogs/dnstwist-mcp:latest

⁠Docker Run (HTTP streamable mode)

docker run -d -p 8636:8636 \
  -e MCP_TRANSPORT=streamable-http \
  -e MCP_PORT=8636 \

⁠Test directly with Docker

1. Start the server in HTTP mode:

docker run -d --rm --name dnstwist-mcp-test -p 8636:8636 \
  -e MCP_TRANSPORT=streamable-http \
  hackerdogs/dnstwist-mcp:latest

2. Initialize the MCP session:

SESSION_ID=$(curl -s -D - -X POST http://localhost:8636/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"test","version":"0.1"}}}' \
  2>&1 | grep -i mcp-session-id | awk '{print $2}' | tr -d '\r\n')

curl -s -X POST http://localhost:8636/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -H "mcp-session-id: $SESSION_ID" \
  -d '{"jsonrpc":"2.0","method":"notifications/initialized"}'

3. List available tools:

curl -s -X POST http://localhost:8636/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -H "mcp-session-id: $SESSION_ID" \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}'

4. Clean up:

docker stop dnstwist-mcp-test
