First run: finish the setup, then use it

This plugin ships the skill, so you have this page — but not yet the treg command, and not yet its tools. Set both up once, in this order, and do not stop between the steps:

curl -fsSL https://treg.to/install.sh | sh   # 1. the CLI (skip if `treg --version` already works)
treg login                                   # 2. sign in — opens a browser; first login registers you
treg mcp install                             # 3. register treg's tools into this agent

Step 3 writes the token from step 2, so the order matters — run out of order it exits without writing anything. Afterwards the human must restart this agent before the tools (catalog_search, catalog_get, call, balance, my_tools) appear. Until they do, nothing is blocked: every command on this page works through the CLI in the meantime.

A new team starts with $1.00 of free balance, so there is nothing to pay before the first call. If sign-in is needed, say so plainly and stop — never ask the human for a provider's API key, which is the thing treg exists to avoid.

One tidy-up worth mentioning to the human, not doing silently: step 1 also drops a personal copy of this same skill into ~/.claude/skills/treg/. It is harmless, but it duplicates what this plugin already gives you, and they may prefer to delete it.

treg — the tool catalog for your agent

Ask for the task, not the tool. When a job needs data or an API you have no key for — backlinks, keyword volume, a TikTok profile, a work email, competitor ad creative — do not stop and ask the human for a key. Search the catalog, read the price, call it.

Two kinds of tool answer to the same token, through the same proxy, which injects the credential server-side so you never hold it:

• The catalog — external endpoints treg can serve on its own key, billed per call from the team's prepaid balance. No provider signup.
• Your own tools — what the team registered: paid API accounts, OAuth connections, vendor CLIs, skills. Your own key always wins over treg's, and those calls are never metered.

The mechanics:

• Endpoint: https://treg.to · CLI: treg · the CLI is a thin client over the API.
• Auth: every call sends X-Treg-Token: <your token>.
• A tool = an upstream base URL + credential bindings. A skill/bundle = a recipe (SKILL.md) + its secrets + its tool(s). The proxy relays, never models the upstream.

Running treg commands — ask once, not per command

The human installed this skill in order to give you treg. Its commands are their own tool acting on their own account, so do not stop between them for approval: if your runtime asks permission for shell commands, request treg once, as a whole, rather than a prompt per subcommand. Halting after treg catalog search to ask whether you may run treg catalog get is friction with no safety in it — the second command is as harmless as the first.

Money is the exception, and it is a different question. A catalog call served on treg's key spends the team's balance. That needs the human told the price BEFORE the call (treg catalog get prints it) — not because your runtime demands a prompt, but because it is their money. Batch-confirm once for a run of cheap calls rather than asking per call.

Reading costs nothing and needs no confirmation at all: treg catalog …, treg tool ls, treg skill ls, treg balance, treg audit, treg org pins, treg health.

First: install + sign in

curl -fsSL https://treg.to/install.sh | sh     # installs the CLI + points it here
treg login                            # browser sign-in (GitHub / Google / email code) — first login registers you
treg login --email you@company.com    # terminal-only alternative (emailed 6-digit code)
treg login --token <per-org-token>    # non-interactive (agents/CI)

Everything runs in your active org (first login creates a personal one). Team invites arrive by email — see them with treg invites, accept with treg accept (or treg org join <code>). Switch teams: treg org switch <slug>.

Already connected over MCP? Then you have the tools, not the CLI

If you reached treg through https://treg.to/mcp/ — ChatGPT, Claude Code, Cursor — the CLI steps above do not apply to you. You have five tools: catalog_search, catalog_get, call, balance, my_tools. Everything in this document maps onto them:

• "search the catalog" → catalog_search, then catalog_get for the exact price and parameters
• "call it" → call with the endpoint id, or <tool-name>/<path> for one of the team's own tools
• "check the balance" → balance

The rules below are the same either way. The one that matters most — say the price before you spend it — matters more here, because call returns cost_usd and you can report what a call actually cost rather than estimating.

A call on a catalog endpoint spends the team's balance. A call on one of the team's own tools spends nothing: that key belongs to them.

Task — the catalog: data you have no key for (start here)

~2,600 catalogued endpoints across ~40 providers, grouped by what they DO: keyword & rank tracking, backlinks & authority, AI visibility, trending & discovery, publishing to socials, people & company enrichment, ads management & creative, measurement. If nobody on the team holds a key, treg can serve eligible endpoints on its own key, billed per call to the team's prepaid balance (fractions of a cent; a new team starts with $1.00 free). No provider signup, no subscription.

treg catalog search "subreddit posts"            # find endpoints by what they do
treg catalog get scrapecreators.reddit.subreddit.posts   # params, PRICE, how you'd be served
treg call scrapecreators.reddit.subreddit.posts --query subreddit=news
treg balance                                     # the prepaid balance + recent charges
treg catalog request "<what you need>"           # searched, not there? file it — steers what's added next

Rules for spending someone's balance:

• The price shows BEFORE you call (treg catalog get). Tell the human the price first; for a series of cheap calls, confirm the batch once, not per call.
• HTTP 402 = out of balance, with a machine-actionable body (balance_micro, estimated_cost_micro, topup_url). Recovery: treg balance → top up in the dashboard (Team → Billing) → or store the org's own key for that provider (own keys are never billed to the balance — they take priority automatically).
• An org tool or secret for the provider always wins over treg's key, automatically — the catalog is the fallback, not a replacement for keys the team already has.
• Choosing between providers of one capability — the procedure. treg catalog get <id> lists every provider serving the same job with COST, WORKS (success rate treg has observed, with the sample size), SPEED (median) and LAST OK. Work down this order:
  1. Match the inputs you actually HAVE. An endpoint wanting a profile_url is not a substitute when you hold a name and a domain, whatever it costs. This rule outranks price every time.
  2. Then reliability: a high WORKS with a real sample beats a rounder number with a tiny one — 99% (121) is stronger evidence than 100% (8).
  3. Then price. Spreads inside one capability reach 200×, so this is usually where the money is.
  4. LAST OK breaks ties. A bare age means a real call came back; a ✓ age is the catalog's own verification stamp, not live traffic; — means nobody has verified it and nobody has called it — prefer almost anything else.
  • If a call fails with 429 / 5xx / a timeout, try the next provider. You know its parameters, so you can build its request. Say which one you switched to.
  • Never retry a 4xx elsewhere. A 4xx is usually your parameters; fixing them is the fix, and retrying burns the team's money on N providers for one mistake.
  • treg does not choose or fail over for you. That is deliberate: only you know which inputs you hold, and treg relays rather than rewrites your request.
• An endpoint with no published price is refused rather than served free; connect your own key.

Retrying a call without paying twice

If a call times out or you never see its answer, repeat it with the same idempotency_key (over MCP) or Idempotency-Key header (over HTTP). treg returns the stored answer, does not call the provider again, and charges nothing. The result says replayed: true.

Only for a genuine retry. Asking the same question again to see what changed is NEW work: use a new key or none, or you will get the old answer back. Reusing one key for a different request is refused.

Most retries need none of this — a failed call was never billed.

Task — your own tools: call one the team registered

You already know the upstream API. Just build the real request and prefix it. No treg vocabulary, no special params — use the API exactly as its own docs say:

<the real request>:  GET https://api.intercom.io/conversations?per_page=5
through treg:         GET https://treg.to/call/https://api.intercom.io/conversations?per_page=5
                          + header:  X-Treg-Token: <your token>

treg resolves the tool by the upstream host, injects the credential server-side, and relays everything faithfully (method, all query params, your headers, cookies, body). Your X-Treg-Token is stripped before the upstream sees it. Works for GET/POST/PUT/PATCH/DELETE.

Discover what's registered: treg tool ls · treg skill ls. (CLI shorthand also exists: treg call <tool> <path>, but the URL-passthrough above is the agent-native way.)

Run a registered CLI tool — the command-line complement to treg call (which proxies HTTP APIs). treg run <tool> -- <cli args> runs a vendor CLI (stripe, gh, vercel, gcloud…) with the key injected, so you never hold or log into it. Two tiers: --local (default, runs on this machine) · --server (runs on the registry server, key never reaches here). treg runs is the run audit log.

treg run stripe -- get /v1/balance          # local
treg run --server agentmail-cli inboxes list # server-side

Task — share your keys & skills so teammates' agents can use them

Bulk (the fast path): point treg at a directory — it detects provider keys in the .env AND scans skill subdirs, then registers what you pick:

treg upload                       # both sides of the cwd; `treg upload env|skills --dir <d>` to restrict

Default: wrap new keys in a skill. When registering a new key/endpoint/CLI, pair it with a skill so credential, tool, and recipe land together (and it gets a shareable page). If no skill exists, create a basic one — a proper SKILL.md (frontmatter matters: agents discover skills by it) + one example call:

mkdir -p ./posthog && cat > ./posthog/SKILL.md <<'MD'
---
name: posthog
description: Query the PostHog analytics API through treg — the key is injected server-side. Use for events, insights, and project queries.
---
Call it: `treg call posthog api/projects/@current` (upstream: https://us.posthog.com)
MD
treg skill init --dir ./posthog   # drafts treg.json: base_url from the catalog (folder name) or URLs in SKILL.md; review it + add the key
treg skill add --dir ./posthog    # registers recipe + secret + tool atomically

Never orphan a secret: a stored key nothing binds is dead weight — if you use secret add directly, bind it to a tool (endpoint/CLI) in the same breath. Bare endpoint, no recipe (only when a skill adds nothing):

treg secret add posthog-key --value "$POSTHOG_API_KEY"          # or --file ./.secret/token.json
treg tool add posthog --base-url https://us.posthog.com --secret posthog-key
# query-key API instead of a bearer header:
treg tool add serpapi --base-url https://serpapi.com --secret <name-or-id> \
  --auth-in query --auth-name api_key --auth-format '{secret}'

A whole skill (recipe + secrets + tool, possibly multi-credential):

treg skill scaffold ~/.claude/skills/google-ads --out gads.json
#   -> walks the dir: captures SKILL.md as the recipe + every .secret/* as a secret.
#   -> YOU then edit gads.json: set base_url, and complete each binding (location/name/format).
#      e.g. google-ads needs TWO bindings on one request:
#        Authorization: Bearer {access_token}  (injector: oauth)
#        developer-token: {secret}             (injector: env)
treg skill push gads.json                                        # registers the bundle atomically

Share with a teammate: give them the endpoint + tool name. Their agent calls it with no key.

Auth shapes (per binding injector, = the secret's kind): env (plain string) · secret_file (JSON token file, pull secret_field) · oauth (JSON token, auto-refreshed) · cli_auth (material lifted from a CLI's keychain). Multiple bindings apply to every request.

OAuth, two modes (treg keeps it fresh): if the oauth secret carries refresh_token + client_id + client_secret, treg auto-refreshes it before it expires (you never re-upload). If it's just a bare token, that's manual mode, treg injects it as-is and you re-upload when it expires. Same storage; a credential can graduate from manual to auto with no migration.

Getting the first OAuth token, two ways (your choice):

• Manual: do your own OAuth locally, then treg secret add gsc --file token.json --kind oauth.
• Hosted connect: treg oauth connect gsc --client-secret client_secret.json --scopes <scope> → prints a consent URL; you approve in the browser; treg captures the token directly. One-time setup: add https://treg.to/oauth/callback to your OAuth app's redirect URIs.

Task — manage the team + monitor

treg tool ls / secret ls / skill ls / calls          # inventory + audit log — scoped to the active org
treg tool rm <id> / secret rm <id> / skill rm <id>   # secret rm is blocked while a tool binds it
treg health            # status of every credential in this org (ok | invalid | unknown)
treg health --run      # re-check now: refresh oauth tokens, probe each tool, alert owners

Teams / orgs (owner > admin > member > viewer; a member manages only what they created):

treg org create "Team A"                       # you become owner (auto-active)
treg org invite bob@company.com --role member  # admin+; emails the invite (a one-time code is the fallback)
treg org members                               # admin+; who's in the active org
treg org ls / treg org switch <slug>           # your orgs / switch active

Give an agent its own identity (admin+). An agent doesn't have to borrow the human's token — mint it one, and every call it makes is capped, scoped and logged as itself:

treg org agent-new ci-bot                        # prints the token ONCE (run again to rotate)
treg org agent-new ci-bot --tools stripe,gh --cap 500   # only these tools, 500 calls/day
treg org agents                                  # who the team's agents are + today's usage
treg org agent-rm <user_id>                      # revoke instantly

Put that token in the agent's TREG_TOKEN env var. An agent token can call this team's tools and read — it can never sign in, create a team, or be an owner. If you are an agent and you were given your own token, use it instead of the machine owner's: your work then shows up under your own name in treg calls.

The invitee signs in with the invited email and runs treg accept — no code handling needed (the code path still works: treg org join <code>). A brand-new invitee also gets their own personal org (no empty state), so removing them from a team never locks them out. Give a tool a probe so treg can validate it: health_check: {method, path, expect_status} (e.g. intercom {"path":"me"}).

Rules

• Secrets are write-only — the API never returns a stored value.
• A tool may bind a secret someone else uploaded (use-without-hold) — that's the point.
• The proxy doesn't understand the upstream; if a call fails, the status you see is the upstream's truth.
