Docker Local Bridge Template

Local-bridge template for containers, images, and logs. Astrail cloud does not attach to host Docker sockets; run a local MCP bridge.

Credential setup

local-bridge

This template is not executable on Astrail cloud. Use a local MCP bridge with access to the host runtime, then point your agent client at that local endpoint.

Install a local Docker MCP server (stdio/HTTP) that can reach the Docker engine, then register that endpoint in your agent client. Do not paste socket paths into Astrail cloud credentials.

CLI: astrail connectors describe preset-docker

Hosted MCP endpoint

/api/mcp/preset-docker

Private servers require an Astrail API key in the Authorization header.

Astrail does not evaluate generated TypeScript inside Next.js. Hosted calls are routed through stored tool metadata and endpoint maps.

Tools

docker_list_containers

List containers and current status via a local Docker bridge.

docker_get_logs

Fetch recent logs for a container via a local Docker bridge.

docker_restart_container

Restart a container after approval via a local Docker bridge.
