Hermes Agent

Connect Hermes Agent to Cosmonic Desktop's built-in MCP server via Settings → MCP Server → Install in your AI client. Hermes' own CLI is interactive, so Desktop's toggle edits ~/.hermes/config.yaml directly; the equivalent manual command (using the daemon binary's path on your platform—macOS shown):

hermes mcp add cosmonic --command "/Applications/Cosmonic Desktop.app/Contents/Resources/cosmonicd" --args mcp serve

What Hermes can do once connected

Its full tool surface (observe, deploy, build) and the guardrails are covered in Connect Coding Agents; the tools work only while Cosmonic Desktop is running. Desktop can also install the cosmonic-sandbox skill for Hermes from the first-run offer or Settings → Agent skills, which lands at ~/.hermes/skills/cosmonic-sandbox/.
