This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

Name	Description
`SSH_MCP_CONFIG` Optional	Optional explicit path to ssh-session-mcp.config.json when the config is not in the current working directory.
`SSH_MCP_INSTANCE` Optional	Optional runtime instance id used to isolate state across multiple MCP clients or agents.
`VIEWER_PORT` Optional	Viewer HTTP port. Use auto to allocate a free local port, or 0 to disable the browser viewer.

`SSH_MCP_DEBUG` Optional	Set to true or 1 to expose browser-side debug controls intended for demos and local troubleshooting.
`SSH_HOST` Optional	Legacy single-target SSH host when not using ssh-session-mcp.config.json device profiles.
`SSH_PORT` Optional	Legacy single-target SSH port when not using ssh-session-mcp.config.json device profiles.
