commit 2b9a8ffea45b629b604762cfad644d1ba8fa8c6d equwal <13551856+equwal@users.noreply.github.com> 2026-10-03 21:42:26 -0700 Add sshp agent skill and read-only MCP server The skill teaches agents to run fleet checks with sshp: read-only first, dry run before writes, BatchMode and timeouts, per-host exit codes. The stdio MCP server wraps the installed sshp binary with a host allowlist and a read-only command policy that only the config can lift.

It adds two things: + +- **`skills/sshp/SKILL.md`**: an agent skill that teaches when and how to use sshp: read-only checks first, `-n` dry runs before writes, `BatchMode` and timeouts so nothing hangs, output grouping, and per-host exit codes. It works in the skills folders of Claude Code, Codex, Copilot CLI and Antigravity. +- **`sshp_mcp.py`**: a stdio MCP server (Python 3 stdlib only) with two tools: + - `sshp_run(command, hosts?, max_jobs?, timeout?, user?, dry_run?)` returns JSON with each host's output and exit code. + - `sshp_hosts()` lists the allowlisted hosts and whether writes are enabled. + +sshp-ai does not include sshp's code. Install sshp yourself. + +## Safety model + +The operator sets the limits in a config file. The model cannot change them. + +- **Host allowlist.** Only hosts in the hosts file can be targeted. +- **Read-only by default.** A command must start with an allowed verb (`uptime`, `df`, `systemctl status`, `journalctl`, `docker ps`, ...) and must not contain shell metacharacters (`; | & > < $ \` ( )`). Write-like forms such as `find -delete`, `systemctl restart` or `date -s` are refused. +- **Writes need `"allow_write": true`** in the config. Only the operator can set it. +- ssh runs with `BatchMode=yes` and `ConnectTimeout=10`, so a prompt fails fast. The whole run has a timeout (default 60 s, max 600 s). + +## Install + +1. Build and install sshp (see its README). It must be on `PATH`, or set `"sshp"` in the config. +2.

Register the MCP server, for example in Claude Code: + + ```sh + claude mcp add -s user sshp -- python3 /path/to/sshp_mcp.py + ``` + + Other clients take the same command (`python3 /path/to/sshp_mcp.py`) in their MCP config. + +## Example result + +```json +{ + "sshp_exit_code": 1, + "dry_run": false, + "hosts": { + "web1.example.com": {"output": " 10:00:01 up 3 days, load average: 0.10", "exit_code": 0}, + "db1.example.com": {"output": "ssh: connect to host db1.example.com port 22: Connection refused", "exit_code": 255} + }, + "sshp_stderr": "" +} +``` + +sshp merges each host's stdout and stderr into one stream, so `output` holds both. + +## Tests + +```sh +python3 -m unittest -v test_sshp_mcp +``` + +The policy tests run anywhere.

Show the user the host list and command.

A password prompt or host-key prompt then fails fast instead of blocking. +4. **Limit concurrency for heavy work.** Default `-m 50`. Use `-m 1` for rolling changes (one host at a time), `-m 5` for anything that loads the hosts. +5. **Read exit codes per host.** Always pass `-e`. sshp prints `[host] exited: N (T ms)`. Report the hosts that failed, not only the overall status. sshp itself exits non-zero if any host failed. +6. **Use a hosts file.** `-f hosts` reads one host per line (`user@host` works).
