treg
superdesigndev/treg
Tool catalog for agents: search ~2,600 external endpoints (SEO and SERP, backlinks, social, people and company enrichment, ad libraries, scraping) by the task you want done, read each one's parameters and per-call price, then call it with the credential injected server-side. Ships the skill plus an MCP row that stays disabled until TREG_TOKEN is set.
Install
Add treg to DeepSeek Harness
via npm
Resolves a published tarball rather than cloning the repository, and installs without any extra setup. Swap `web` for your profile name if you run another one.
via GitHub · npm package
Installing from GitHub runs the project's build script, which pnpm blocks until you allowlist it — run the command once and pnpm prints the exact key to add under `allowBuilds` in ~/.dsh/profiles/web/pnpm-workspace.yaml.
Due diligence
Before you install treg
- Source of record: superdesigndev/treg — present in the community registry that DSH's own plugin market installs from.
- Licensed under NOASSERTION.
- Detected: terminal surface. Read the source before granting these.
- A listing here is not a security review. Plugins run with your agent's permissions.
What treg does
treg is a DeepSeek Harness plugin that gives an agent a searchable catalogue of roughly 2,600 external API endpoints across about 40 providers. It covers SEO and SERP data, backlinks, social and trend data, people and company enrichment, advertising, measurement and scraping. The agent searches by task rather than vendor, inspects parameters and per-call pricing, then calls the selected endpoint.
The plugin supplies a treg skill and an MCP entry. The MCP entry remains disabled until TREG_TOKEN is set. Through the treg CLI, catalog search finds tools, catalog get shows parameters and prices, and call sends the request. Authentication is injected server-side by the registry; the agent supplies its X-Treg-Token, not the upstream provider's key. treg upload can also register selected .env credentials, skills and installed CLIs, while treg scan previews what would be registered.
This DeepSeek Harness plugin is intended for agents that need occasional access to specialist data services without separate provider accounts, or for teams sharing their own API credentials and command-line tools. It reaches the terminal through the treg CLI and can send requests to external services with the agent's permissions. It is a poor fit when calls must stay local, when an external registry must not handle requests, or when prepaid metering is unsuitable: catalogue calls using treg's key consume team balance, and the README documents a hosted service at treg.to.
treg documentation
Configuration
The plugin uses the registry token in TREG_TOKEN for its MCP entry. Without that variable, the MCP row stays disabled. The CLI uses the same token through its X-Treg-Token request header after treg login; the README lists GitHub sign-in, a one-time code with --email, and --token for agents or CI.
Commands
| Command | Purpose |
|---|---|
treg catalog |
List catalogue platforms, busiest first. |
treg catalog search "..." |
Search endpoints by the task they perform. |
treg catalog get <tool> |
Display parameters, price and an example response. |
treg call <tool> [path] |
Call a catalogue or registered tool; --query supplies query values. |
treg balance |
Show remaining credit, calls in flight and recent spend. |
treg topup |
Add funds or configure automatic top-ups. |
treg tool ls |
List tools shared with the team. |
treg health |
Check credential health. |
treg scan |
Preview keys, skills and CLIs that an upload would register. |
treg upload |
Register detected items; --replace updates existing ones. |
treg secret add |
Store a secret for later injection. |
treg add |
Register an endpoint using --base-url and --secret. |
treg calls |
View the call audit log. |
upload env --select can select known providers from .env; the scanner matches keys against roughly 80 providers and examines skill subdirectories and installed catalogue CLIs.
How it behaves
For a catalogue call, credential selection prefers a team-registered tool, then a team-stored provider secret, then treg's own key. Team credentials are not metered; calls using treg's key use the team's prepaid balance. When no published price exists, the endpoint is refused. If several providers match, the caller chooses rather than receiving silent failover. An out-of-balance response is HTTP 402 and includes balance_micro, estimated_cost_micro and topup_url.
Requirements
The README documents the hosted registry at treg.to and says it can be self-hosted. The Claude Code installation loads the skill as treg:treg; its first run guides CLI setup, sign-in and treg mcp install. The command-line examples require a working treg CLI and credentials.

Vladimir-Human
Skills and optional MCP rows for ten Russian marketplaces: price comparison across Wildberries, Detsky Mir and Yandex Market, plus per-source search, product cards and reviews. The 13 skills load on install; both MCP rows stay disabled until RU_MARKETPLACE_MCP_DIR points at a local clone, which needs Python 3.12+ and uv.
No one-line install — this plugin lives inside a larger repository and publishes no npm package.
