### Description (declared)

# mcp-switchboard-server-harness

A first-party stdio MCP server that gives a coding agent the basics on a
remote machine: filesystem, search, git and shell tools. It is a normal MCP
server, so [mcp-switchboard-client](../../client) tunnels it like any other.

Tools (26; full schemas and behaviour in [spec.md](../../spec.md#4-harness-server)). The core
set deliberately mirrors the tool suite a Claude Code / opencode-style agent already knows:
`bash`, `read`, `write`, `edit`, `glob`, `grep` — plus the extras listed below.

- **Files:** `read` (line-numbered `N: ` output, paged with `offset`/`limit`, lists directories),
  `write`, `edit` (exact-string replace, returns a diff; `dry_run`, `replace_all`),
  `apply_patch` (unified diff, multi-file, all-or-nothing, `dry_run`),
  `file_delete` (directories need `recursive=true` unless empty), `file_move`
- **Search:** `glob` (honours `.gitignore`, newest first), `grep` (regex over contents)
- **Run:** `bash` (`mode` = `full`/`head`/`tail`/`grep`), `run_tests` (auto-detects
  pytest / go / npm / cargo, returns structured failures), `output_read` / `output_grep` (page through output that was
  cut; commands return an `output_id`), and `process_start` / `process_read` / `process_kill` for
  long-running work. Long *waits* are never blocking calls: `wait_for_start` + `wait_for_poll`
  watch a shell predicate harness-side (satisfied when it exits non-zero) so no hub per-call
  deadline can kill them; a blocked command that hits a timeout returns its partial output
  (`timed_out`, `exit_code` 124), never an error
- When driving cluster or fleet CLIs through `bash`, prefer their machine-readable flags
  (`--json` / `--parsable` / `-h`) over default table output — Slurm table columns are
  misalignment-prone and mis-read silently
- **Git:** `git_status`, `git_diff`, `git_show`, `git_log`, `git_branch`, `git_add`, `git_checkout`,
  `git_commit`, `git_push` — `git_push` declares itself **irreversible** (tool `_meta`), so the hub
