# Tools and integrations: MCP servers, skills, clients, gateways and libraries

> **TL;DR** Official tools first; the rest is **unaudited community code**, mostly days old (★ and push as of 2026-09-23). Vet per [[ideas/community-repos]] before granting shell, browser or key access.

Pattern IDs: [[ideas/patterns]]. Licence MIT unless stated. Numbers: the author's.

| Your job | Look at |
|---|---|
| Guard a coding agent | skills, plugins, hooks |
| Give an agent Jev as a tool | MCP servers |
| Email, helpdesk, CRM, ops | n8n node, Composio |
| E-commerce store | Magento 2 module |
| Rank, filter or lint from code or SQL | CLIs, libraries |
| Call Jev from Go, R, PHP, Rust | SDKs table |
| Run a Jev-like model locally | open replicas (not TypeSafe) |

Not captured: Shopify, Gorgias, Zendesk, Gmail, WooCommerce integrations.

## Official (TypeSafe)

- Python `typesafe-sdk` → [[reference/python-sdk]]; JS `@typesafe-ai/sdk` → [[reference/javascript-sdk]]; skill and Claude Code plugin `typesafe-ai/skills` → [[reference/agent-skill]].
- `system-one-adapter`, an LLM-backed stand-in → [[reference/system-one-adapter]]. All repos: [[entities/github-repos]].

## MCP servers

| Tool | Exposes | Install | ★ · push | Note |
|---|---|---|---|---|
| [jev-scout](https://github.com/kierandotai/jev-scout) (kierandotai) | guarded search, fetch, report; scores relevance, credibility, steering; SSRF guard | clone, `claude mcp add` | 0 · 2026-09-21 · no licence | 88% relevance, 96% credibility on a labelled set. P17 |
| [BrowserClaw](https://github.com/GoldenLoaf24h/browserclaw) | Chrome extension, 49 tools; a goal loop decides with Jev, escalates destructive keywords | release zip | 6 · 2026-09-23 · NOASSERTION | your logged-in Chrome. P12 |
| [Jevbridge](https://github.com/tacticocc/Jevbridge) (tacticocc) | `jev_decide`, `jev_gate`, `jev_computer_use` + ACP; LLM or heuristic stand-in without a key | clone | 40 · 2026-09-21 | stand-in lacks Jev's calibration. P03, P14 |
| [tenbin](https://github.com/simota/tenbin) (Shingo Imota) | design-time MCP + skill: decompose, lint, measure thresholds, rerank, cost guard | clone | 2 · 2026-09-21 | production calls the SDK |

MCP also in: jev-rs, jev-browser, codex-context-diet, JevGuard. Elsewhere: jev-mcp, typesafe-mcp, skillbox → [[ideas/repos-agents]].

## Agent skills, plugins and hooks

P03 |

| [Switchloom](https://github.com/instructa/switchloom) (Instructa) | Codex skill routing tasks across models, Jev mode | `cargo install` | 1 · 2026-09-20 | **author advises against**: no Jev gain in two pilots. P02 |

| [Jevify](https://github.com/altryne/jevify) (altryne) | offload bulk judgments; "Jevify this" audits a product | `npx skills add altryne/jevify --skill jevify` | 25 · 2026-09-21 | not ryana/jevify |
| [Jev Architect](https://github.com/karanb192/jev-architect) (Karan Bansal) | find, design, test decision loops; may say "keep it in code" | `npx skills add` or plugin | 6 · 2026-09-20 | cf. [[ideas/consult]] |
| [prompt2jev](https://github.com/sumleo/prompt2jev) (sumleo) | prompt or LLM code → linted `request.json` + script | plugin or `npx skills add` | 3 · 2026-09-21 | P01 |
| [clay-jev-people-ranker](https://github.com/promptgtm-shared/clay-jev-people-ranker) (PromptGTM) | Clay filters, Choice + Noul qualify founders | `install_skill.py` | 0 · 2026-09-21 | 577 people in 20.1 s; 490,395 tok ≈ $0.0206 (= $0.042/Mtok). P19 |

## Gateways and access routes

- **OpenRouter** (`~typesafe/jev-latest`), **Vercel AI Gateway** (`typesafe-ai/jev`): `verified` in SDK 0.7.1 via `base_url`/`TYPESAFE_BASE_URL` ([[reference/python-sdk-internals]]); their prices and terms apply.
- **New API** plugin ([@t0ng7u](https://x.com/t0ng7u/status/2102062876819374482)) and **OpenCode Zen** (Jevvy; [jev-agent-skill](https://github.com/yuyang2230/jev-agent-skill), model `jev-1.13-free` at $0): `unverified`.
- **impossibl** serves Laya, not Jev, on a compatible endpoint.

## Open replicas and Jev-compatible servers

**Trust note.** None is TypeSafe or runs Jev. `/v1/systemone` compatibility is the wire shape, not the calibration [[patterns/confidence-routing]] needs; several compute their own `confidence`. Re-measure on your labels ([[ideas/measurements]]).
