Available tools 6

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

compare

compare

Side-by-side spec table with offers and the fields that differ. Pass 2-10 product_ids, or a category with filters. Example: {"product_ids":["prusa-core-one","bambu-lab-p1s"]}

fit

check_fit

Does this part fit that machine? Returns a verdict with the rule id and version that decided it, or the missing fields. Example: {"subject_id":"e3d-v6-1-75mm-brass-nozzles-0-40mm-1-75mm","target_id":"prusa-mk4s"}

product

get_product

Full specs with per-field confidence and source, every offer with verified time, 30/90-day price range. Example: {"product_id":"prusa-mk4s"}

products

search_products

Find products by name or by category and spec filters; returns key specs and the best in-stock offer. Example: {"query":"hardened 0.4","category":"nozzle","limit":5}

report

report_issue

Flag a wrong spec, price or fit verdict. Reports never edit facts; two independent reports mark a fact disputed. Example: {"entity_type":"product","entity_id":"prusa-mk4s","field":"nozzle_thread","claim":"MK4S uses the Nextruder thread"}

stock

check_stock

Availability and price per merchant, re-verified live when the data is over an hour old. Example: {"product_id":"e3d-v6-1-75mm-brass-nozzles-0-40mm-1-75mm","merchant_id":"e3d-online-com"}

compatsy 3D printing — questions

Answers built from our own checks of this server.

What can compatsy 3D printing do?

It exposes 6 tools, read directly from the server on our last check. Among them: check_fit, check_stock, compare, get_product, report_issue, search_products. 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 compatsy 3D printing working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 572 ms. The bar chart above shows every period we have measured.

How do I connect compatsy 3D printing?

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

Does compatsy 3D printing need an API key?

No. compatsy 3D printing completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is compatsy 3D printing?

It answers our handshake in 572 ms on average, which is faster than 19% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is compatsy 3D printing open source?

The code is open source: it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at compatsy.com, which runs on its operator's own terms.
