LABSCO SUMMARY

The credit model is written into the tool list, which is unusual and genuinely useful.

check_screenshot_cache is documented as free, sign_screenshot_url charges on render rather than on signing, and batch_screenshots rolls credits back for URLs that fail — so the cost of a workflow can be reasoned about before it runs, with get_usage and the quota.warning and quota.exceeded webhook events closing the loop. The trap is the cache probe itself: it tells the truth only when passed the identical parameter set take_screenshot would use, so a probe missing one option reports a miss on a capture that already exists.

What it is

A client for the SnapRender screenshot API with 11 tools: single and batch capture, a free cache probe, signed URLs, page-content extraction, webhook management and usage reporting.

What you get

A capture tool that takes three kinds of input: take_screenshot accepts exactly one of url, html or markdown and returns PNG, JPEG, WebP or PDF, with device emulation for iPhone, Pixel and iPad, plus dark_mode, full_page, custom width and height, block_ads, block_cookie_banners, hide_selectors and click_selector.
A cache probe that costs nothing: check_screenshot_cache reports whether a capture already exists and is documented as not counting against your quota, provided you pass the same parameters take_screenshot would use so the cache key matches.
Screenshots you can hand out without the key: sign_screenshot_url returns a signed URL that expires after expires_in, free to generate, with one credit charged when the URL is rendered.
Page content without the picture: extract_content returns markdown, plain text, raw html, an article with title, author and excerpt, all links, or metadata from OG tags — narrowed by selector and capped by max_length.
Batching as a job rather than a loop: batch_screenshots takes 1-50 urls sharing one option set and returns a job ID, get_batch_status polls it and hands back presigned download URLs valid for 24 hours, and credits for failed URLs are rolled back.
Notification instead of polling: create_webhook subscribes to screenshot.completed, quota.warning at 80% used and quota.exceeded at 100% used, with payloads signed HMAC-SHA256 and a returned secret to verify them; list_webhooks, test_webhook and delete_webhook manage the set, capped at 5 per account.
Quota visible before you hit it: get_usage returns this month's screenshots used and the account limit.

Requirements

SNAPRENDER_API_KEY. Everything else is decided per call: take_screenshot needs exactly one of url, html or markdown, and check_screenshot_cache needs the identical parameter set as the capture it is asking about or the cache key will not line up. sign_screenshot_url is the exception in the other direction — the URL it returns is usable without the key until expires_in runs out.

Setup effort

One command plus a key — npx snaprender-mcp, then supply credentials

See installation options

USE CASES

01

Grabbing a clean shot of a page that fights back

Turn off the ads and the cookie banner, hide the elements you do not want, and capture the full page at the viewport you care about.

take_screenshot

02

Rendering a list of URLs without blocking on each one

Submit the whole list as a single job under one option set, poll it for presigned download links, and let a webhook tell you when it lands instead of watching.

batch_screenshotsget_batch_statuscreate_webhook

03

Checking a capture exists before spending a credit

Probe the cache with the exact option set the capture would use, read where the month's quota stands, and only then render.

check_screenshot_cacheget_usagetake_screenshot

04

Embedding a screenshot where the key cannot go

Sign a URL for an email, a document or a third party, with an expiry you set and the credit charged only when someone actually loads it.

sign_screenshot_url

05

Pulling the words off a page instead of a picture

Extract readable markdown, an article with its title and author, the link set, or the OG metadata — scoped to a selector when the page is noisy.

extract_content

06

Wiring up alerts before the quota runs out

Subscribe an endpoint to the quota warnings, fire a test payload at it to confirm it receives them, and check what is already registered.

11 tools

Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.

`batch_screenshots`

Create a batch screenshot job for multiple URLs (1-50). Returns immediately with a job ID. Use get_batch_status to poll for results (wait 2-5 seconds between polls). All URLs share the same screenshot options. Each URL consumes one credit; failed URLs get credits rolled back.

BEFORE YOU INSTALL

What to know first

Tools you get

11 tools when we connected. The hosted server at app.snap-render.com/mcp lists only take_screenshot, check_screenshot_cache and get_usage; the local npm server adds batch_screenshots, get_batch_status, extract_content, sign_screenshot_url and four webhook tools.

Requires

npx on PATH

Where it runs

Both documented clients run the server on your machine.
