Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

MCP server for parcel tracking in Korea and abroad (CJ대한통운, 우체국, 한진, 롯데, 로젠, 쿠팡, 일본 야마토/사가와, DHL, UPS…) via Delivery Tracker — status, events, delivered-or-not, batch tracking. 택배 조회 MCP.

Readme

@appmonster/mcp-delivery

MCP server for parcel tracking — Korean carriers (CJ대한통운, 우체국, 한진, 롯데, 로젠, 경동, 쿠팡, 편의점택배…) and global ones (Yamato, Sagawa, Japan Post, DHL, UPS, FedEx, USPS, EMS) through Delivery Tracker. Read-only. Korean carrier names work directly.

택배 조회 MCP 서버 — "이 주문 어디쯤이야?", "오늘 발송분 중 아직 안 간 거?"를 에이전트가 답합니다.

Tools

| Tool | What it does | |---|---| | delivery_track_parcel | one parcel → status (접수/집화/이동중/배송출발/배송완료/실패/수령대기/이상), delivered, needsAttention, last event, event history (KST) | | delivery_track_many | up to 20 parcels → per-parcel status + counts (delivered / in transit / needs attention); errors isolated per parcel; your ref echoed back | | delivery_list_carriers | supported carriers (id + name) with the built-in aliases |

Carrier can be a name (CJ대한통운, 우체국, 한진, 야마토, DHL) or an id (kr.cjlogistics). Unknown names fall back to a live search.

Setup (1 minute, free)

  1. https://console.tracker.delivery → sign in (Google/email) → Create Project → Credentials → Create → copy Client ID / Client Secret (the secret is shown once).
  2. Claude Desktop / Cursor:
{ "mcpServers": { "delivery": { "command": "npx", "args": ["-y", "@appmonster/mcp-delivery"],
  "env": { "DELIVERY_TRACKER_CLIENT_ID": "…", "DELIVERY_TRACKER_CLIENT_SECRET": "…" } } } }

Example prompts

  • "CJ 1234-5678-9012 지금 어디야?" → delivery_track_parcel
  • "어제 발송한 스마트스토어 주문 전부 배송 상태 확인해줘" → naver_list_orders → delivery_track_many (ref = 주문번호)
  • "배송 이상 있는 건만 골라서 고객한테 보낼 문자 초안 써줘" → delivery_track_many → filter needsAttention

Notes

  • Free plan credentials expire every 21 days — the console shows the expiration; create a new pair before then (our nightly canary flags it as AUTH when it lapses). Paid plans get lifetime credentials.
  • Delivery Tracker answers in < 1 s typically; this client gives up after 15 s with a TIMEOUT error instead of hanging the agent.
  • Brand-new labels can take a few hours before the carrier reports anything (NOT_FOUND with a hint).
  • Times are converted to KST (+09:00).
