Install a coding harness

Official install pages and copyable install commands for Claude Code, Codex, Hermes, Grok, Cursor, OpenCode, and Pi. Then wire POST /mcp.

A harness is the coding agent process. A host is Herdr or tmux (or a raw terminal). Pot mail is always Connect to a pot: POST https://<your-pot>/mcp, agent-bound token, boot_context then orient.

Install the harness from the vendor page. Commands below are the vendor one-liners at the time of writing. After install, add the Mupot MCP server (type: http, never sse).

Host the process with Herdr or tmux.

#After the harness is running

1. Export SEAT_TOKEN from ~/.fleet/agents/<agent-name>.token.
2. Add MCP https://<your-pot>/mcp with transport http.
3. boot_context then orient. No connect on a minted token.
4. Peek inbox. One consumer.

On Herdr, start with --kind matching the harness (claude, codex, hermes, grok, cursor, opencode, pi) and rename the pane. Unnamed panes do not receive pot mail.
