交給代理程式安裝

把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式,或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南,先向你展示發布者、端點和登入方式,經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。

閱讀 https://sourceweft.com/mcp/io.github.paperandbeyond23-gif%2Fpropzapi/install.md,並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前,先告訴我它的發布者、端點和登入方式,等我確認。不要把 API 金鑰寫進命令或我會提交的檔案;問我金鑰應從哪裡取得。

README

propzapi-skills

Agent skills for template-based image generation and webpage screenshots. Drop-in skills that let any agent render an image from an HTML/CSS template, snapshot any live URL, and manage a template library — over the propzapi REST API.

Templates are HTML/CSS with {{variables}} and Jinja logic ({% if %}, {% for %}, filters). Fill the variables with one JSON call and get back a rendered PNG/JPEG/WEBP/PDF at a stable URL — no headless browser to run, no fonts to install. Perfect for Open Graph images, social cards, certificates, invoices, receipts, and data charts.

Free to start — grab a key (50-image trial, no card required) and you're rendering from Claude, Cursor, Cline, or your own agent loop in under two minutes.

Pure Python standard library. No dependencies. MIT-0 licensed.

Skills in this repo

SkillPurpose
propzapi-fullComplete toolkit — generate images from templates, capture screenshots, and manage templates

Tools

ToolReturns
generate_image(template, modifications, format, scale, quality)Rendered image {url, width, height, format, bytes}
screenshot(url, full_page, width, height, format)Screenshot of a live page {url, ...}
list_templates()Available built-in and custom templates
create_template(name, html, width, height, variables)Created template with its tpl_... id
embed_url(template, modifications, format)Signed GET render URL for <meta og:image>

Authentication

Set the PROPZAPI_KEY environment variable to your propzapi key. It's sent as the X-API-Key header — the base URL is hardcoded, so the key never reaches any other host.

bash
export PROPZAPI_KEY="your_key"

Get a free key — 50-image trial, no card required. You can also mint one with POST /v1/register → {api_key, plan, credits}. The same key works for these skills and direct REST calls.

Pricing

Each rendered image or screenshot costs 1 credit — the response returns the exact charge in the X-Credits-Cost header, and your balance in X-Credits-Remaining. Listing and creating templates is free.

PlanPriceImages / mo
