What fits, with live prices: specs, fit verdicts with rule ids and stock for home espresso.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

  • search_products

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

  • get_product

    Full specs with per-field confidence and source, every offer with verified time, 30/90-day price range, and the top fits per category with counts. Example: {"product_id":"breville-barista-express"}

  • 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":["breville-barista-express","breville-barista-pro"]}

  • 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":"lucca-puck-screen-58mm","target_id":"breville-barista-express"}

  • check_stock

    Availability and price per merchant, re-verified live when the data is over an hour old. Example: {"product_id":"lucca-puck-screen-58mm","merchant_id":"www-seattlecoffeegear-com"}

  • 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":"breville-barista-express","field":"portafilter_mm","claim":"Breville lists a 54 mm portafilter for the Barista Express"}

Common questions

Is compatsy home espresso safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 8 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, Draugr

README from the maker

compatsy-mcp

compatsy answers "does this part fit that machine, and where is it in stock?" Each category has its own MCP endpoint:

CategoryCoversEndpoint
3D printingprinters, nozzles, hotends, build plates, filament, enclosureshttps://compatsy.com/3d-printing/mcp
Home espressomachines, tampers, puck screens, distribution tools, dosing funnels, basketshttps://compatsy.com/home-espresso/mcp

Specs carry their source and confidence, fit verdicts cite the rule that decided them, and prices come with the time they were last verified.

This repo is the quickstart for the hosted MCP server. Nothing runs locally except an optional stdio bridge.

Connect

Remote (preferred). Any client that supports Streamable HTTP:

{ "mcpServers": { "compatsy-3d-printing": { "url": "https://compatsy.com/3d-printing/mcp" } } }

stdio via npx. For clients that only launch local servers:

{ "mcpServers": { "compatsy-espresso": { "command": "npx", "args": ["-y", "github:elliot-rosen/compatsy-mcp"], "env": { "COMPATSY_MCP_URL": "https://compatsy.com/home-espresso/mcp" } } } }

Claude Code: claude mcp add --transport http compatsy-3d-printing https://compatsy.com/3d-printing/mcp

No account or key. Calls are rate limited per session. The bridge defaults to https://compatsy.com/mcp (3D printing); set COMPATSY_MCP_URL to another endpoint from the table.

Example calls

{"name": "search_products", "arguments": {"query": "hardened nozzle 0.4", "category": "nozzle", "limit": 5}}

{"name": "get_product", "arguments": {"product_id": "prusa-mk4s"}} {"name": "compare", "arguments": {"product_ids": ["bambu-lab-p1s", "prusa-core-one"]}} {"name": "check_fit", "arguments": {"subject_id": " ", "target_id": "prusa-mk4s"}} {"name": "check_stock", "arguments": {"product_id": "prusa-mk4s"}} {"name": "report_issue", "arguments": {"entity_type": "product", "entity_id": "prusa-mk4s", "field": "nozzle_thread", "claim": "MK4S uses the Nextruder thread"}}

Example prompts that use them well:

  • "Will a V6 nozzle fit my Prusa MK4S? If it needs an adapter, say which."
  • "Which hardened 0.6 mm nozzles fit a Bambu Lab P1S, cheapest in stock first?"
  • "Compare the Core One and the P1S on build volume and enclosure."
  • "Which puck screens fit a Breville Barista Express, in stock?"

Verdicts

fits, fits_with_adapter, does_not_fit or unknown. Unknown is an answer: it lists the spec fields that are missing rather than guessing. Every rule needs two independent sources, one from the manufacturer, before it can decide anything.

Editor rules

rules/cursor.mdc and rules/windsurf.md tell Cursor or Windsurf agents when to call compatsy instead of guessing fitment from memory.
