Nothing serious here today

Today is the operative word: we check IsPixelWorking every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

findings

list_findings

Every problem (finding) the check can report, with id, severity, title, explanation and whether a fix guide exists.

fix

get_fix_guide

Step-by-step guide (Markdown) for fixing a problem the check found, for the site's platform when one exists (otherwise the general version). With consent_tool, returns the guide for wiring the Meta Pixel to that consent tool instead. Guides exist for: meta.fires_before_consent, meta.not_firing_after_consent, meta.duplicate_pixel, meta.missing_event_id, meta.fbc_not_set, and general.server_side_not_detected (setting up the Conversions API).

page

check_page

Check whether a web page's Meta Pixel (Facebook Pixel) works: cookie consent, duplicate events, event IDs, the ad click ID (fbclid -> _fbc) and signs of server-side tracking. A browser in the EU visits the page twice. Reuses a result from the last 24 hours unless recheck is true. Waits for the result up to wait_seconds (a check takes 20 to 60 seconds); if it is still running, call get_report later.

report

get_report

Read the result of a check by its report id or report link (https://ispixelworking.com/r/<id>): status, grade, problems with explanations and fix guide links, checklist. Reports are kept for 90 days.

IsPixelWorking — questions

Answers built from our own checks of this server.

What can IsPixelWorking do?

It exposes 4 tools, read directly from the server on our last check. Among them: check_page, get_fix_guide, get_report, list_findings. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is IsPixelWorking working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 217 ms. The bar chart above shows every period we have measured.

How do I connect IsPixelWorking?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does IsPixelWorking need an API key?

No. IsPixelWorking completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is IsPixelWorking?

It answers our handshake in 217 ms on average, which is faster than 58% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
