Deployment¶

Deployment Options¶

fan-manager supports local stdio, a loopback-only development listener, a least-privilege stdio container, and a remote authenticated HTTPS boundary. Provider endpoint, credential, selector, identity, and trust material are supplied at runtime through AgentConfig; none is stored in this repository.

Installed stdio process¶

{
  "mcpServers": {
    "fan-manager": {
      "command": "fan-manager-mcp",
      "args": [],
      "env": {"MCP_TOOL_MODE": "intent"}
    }
  }
}

Loopback development listener¶

fan-manager-mcp --transport streamable-http --host 127.0.0.1 --port 8000

Do not expose this listener beyond loopback. Network deployments require direct TLS or an explicitly trusted TLS-terminating ingress, configured authentication, exact MCP_ALLOWED_HOSTS, and an exact trusted-proxy CIDR policy.

Least-privilege local container¶

docker run -i --rm \
  --read-only \
  --cap-drop=ALL \
  --security-opt=no-new-privileges \
  --pids-limit=256 \
  --tmpfs /tmp:rw,noexec,nosuid,nodev,size=64m \
  -e TRANSPORT=stdio \
  registry.example.invalid/fan-manager@sha256:<digest> fan-manager-mcp

The operator projects the selected AgentConfig profile into the process at runtime; the image remains immutable and contains no environment connection profile.

Remote authenticated HTTPS endpoint¶

{
  "mcpServers": {
    "fan-manager": {"url": "https://service.example.invalid/mcp"}
  }
}

Store the real remote URL, outbound identity reference, and TLS-profile reference in AgentConfig, not in MCP client JSON or documentation.

MCP server¶

fan-manager-mcp --transport streamable-http --host 0.0.0.0 --port 8000

Agent server¶

fan-manager-agent --provider openai --model-id gpt-4o

Docker¶

The container must reach the host IPMI device:

docker run -d \
  --name fan-manager-mcp \
  --device /dev/ipmi0 \
  -p 8000:8000 \
  -e TRANSPORT=streamable-http \
  -e PORT=8000 \
  example/fan-manager@sha256:<digest>

Docker Compose¶

docker/mcp.compose.yml runs the MCP server; docker/agent.compose.yml runs the MCP server plus the agent (Web UI on port 9017). Copy .env.example to .env first.

cp .env.example .env
docker compose -f docker/agent.compose.yml up -d

Add privileged: true (or a devices: entry for /dev/ipmi0) to the fan-manager-mcp service so it can drive the BMC from inside the container.

Environment configuration¶

See .env.example for the full set of MCP, telemetry, Eunomia, and tool-toggle variables.
