@fezchat/targon

Bodies for agents, Targon edition. Targon (Bittensor subnet 4, Manifold) is a GPU platform — rentals, confidential VMs, volumes — behind a clean org-scoped REST API. This extension gives any agent the tools to rent a machine by the hour, run jobs on it, and give it back.

Sibling of @fezchat/lium, deliberately not merged with it: the two marketplaces genuinely differ (see guards below), and a user installs only the vendor they hold an account with. No persona of its own — attach it to any agent with mcpServers: [targon].

The tools

A thin wrapper over api.targon.com/tha/v3 — no CLI to install (Targon's is cargo-build-from-source with no release binaries), just fetch with a Bearer token. Endpoints and shapes verified against the official CLI source (manifold-inc/targon-sdk), not just the docs — even exec is an API call, so no shell and no ssh subprocess anywhere:

• targon_inventory(gpu?) — what's rentable, at what $/hour, how many units.
• targon_workloads() — your workloads: uid, status, burn rate.
• targon_up(resource, image?, name?) — create + deploy a RENTAL.
• targon_exec(workload, command) — run a command via Targon's exec API.
• targon_rm(workload) — delete, stop paying.
• targon_balance() — the org's prepaid credits. Top-ups happen at targon.com; agents cannot move money in.

The guards (checked before any spend)

• price ceiling FEZ_TARGON_MAX_USD_HOUR (default $5/h)
• balance must cover at least 1h at the resource's price — Targon has no marketplace TTL. Unlike Lium, nothing upstream stops billing when a lease expires, because there is no lease: a workload bills from deploy until targon_rm. The tools say this in their own descriptions so the model plans the teardown, not just the rent.
• unreadable price or balance refuses — fail closed on money.

Every up / rm / refusal lands in ~/.fez/targon-workloads.json, so "what did compute cost this week" has an answer.

Custody

TARGON_API_KEY lives in the OS keychain (SKILLS & SECRETS), from the human's targon.com dashboard — revocable, scoped to the org's prepaid credits. A leak costs at most the balance, never a wallet. Org slug is auto-discovered (first org on the key), or pinned with FEZ_TARGON_ORG.
