Centerfield Visitor MCP

An MCP (Model Context Protocol) server that automates visitor reservations for the Centerfield building (www.centerfield.co.kr). Use it from any MCP-compatible agent — Kiro CLI / Kiro IDE / KiroCrew, Claude Code, Claude Desktop, Codex CLI, Cursor, Strands Agents (local stdio) and Amazon Quick or any remote client (streamable HTTP) — to register visitors with natural language: single entries, pasted text, survey exports, or Excel/CSV files.

센터필드 빌딩 방문예약을 자동화하는 MCP 서버입니다. 로컬 에이전트(Kiro, Claude Code, Codex, Cursor …)는 stdio로, Amazon Quick 같은 원격 에이전트는 streamable HTTP로 같은 서버를 씁니다.

The stdio server runs entirely locally — uvx downloads and runs it on your machine, and it talks directly to www.centerfield.co.kr. No backend service is required for local agents.

Quick start

mkdir -p ~/.config/centerfield-visitor-mcp
cp .env.example ~/.config/centerfield-visitor-mcp/.env   # fill CF_COMPANY_NAME, CF_PERSON_IN_CHARGE_MOBILE
uvx centerfield-visitor-mcp                               # stdio; every client below can launch this

~/.config/centerfield-visitor-mcp/.env is read automatically, so client configs need no secrets.

Client setup

Agent skill (Agent Skills spec, works in Claude Code / Kiro / KiroCrew): SKILL.md — also shipped as the project skill .claude/skills/centerfield-visitor/SKILL.md.

Tools

Recommended flow: validate_configuration once → preview_* → human confirms → register_*. The default_* arguments fill columns that attendee lists usually lack (visit date/time/floor).

Input constraints

File / text format

Header row in Korean or English; survey-export headers are recognized too (Full Name, Email, 연락처(…), 소속/회사 (…)). Unknown columns are ignored.

이름,회사,전화번호,이메일,방문일,방문시간,층
홍길동,ABC주식회사,01012345678,hong@abc.com,2026-11-15,10:00,12

Lists without date/time columns: pass default_visit_date="2026-11-15", default_visit_time="10:00".

Configuration

.env load order (later overrides earlier): ~/.config/centerfield-visitor-mcp/.env → ./.env → $CF_ENV_FILE; process environment variables always win. Startup logs (stderr) list the files read and any problems.

CF_PERSON_IN_CHARGE_MOBILE must be the mobile number registered as the tenant's approval contact. Run validate_configuration after setup — it checks both values live without creating a reservation.

Remote mode (Amazon Quick, hosted deployments)

CF_TRANSPORT=streamable-http CF_HTTP_HOST=0.0.0.0 uvx centerfield-visitor-mcp    # http://host:8000/mcp
docker build --platform linux/arm64 -t centerfield-visitor-mcp .                 # or the container image

See clients/remote/README.md for the AgentCore Runtime + Cognito recipe and the Amazon Quick connector steps. Works with mcp SDK 1.x and 2.x.

Development & testing

uv sync --group dev
uv run pytest                          # offline unit tests (mocked HTTP)
uv run --with "mcp<2" pytest           # same suite on mcp SDK 1.x
uv run python scripts/smoke_http.py    # streamable-http transport smoke test
uv run pytest -m live                  # read-only checks against the live site (needs a real .env)
CF_LIVE_REGISTER=1 CF_TEST_VISITOR_NAME=... CF_TEST_VISITOR_MOBILE=... CF_TEST_VISITOR_EMAIL=... uv run pytest -m live

The last command creates one real reservation; confirm it in the Centerfield mobile app and cancel it there (there is no cancel API).

How it works

The server holds a single session against the Centerfield site, manages CSRF tokens, verifies the tenant company and approval contact, resolves the floor key, then submits the reservation form. Bulk requests are processed sequentially with a configurable delay.
