Ceramic glaze chemistry: unity formulas, limit checks, substitutes, cones and potters' guides. Connect the official Glazecalc MCP server to Claude, ChatGPT, or Cursor through gate — one gateway URL, no config files, security-checked.

Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “search_materials”: Finds ceramic raw materials (feldspars, clays, frits, fluxes) and, if asked, colorants in Glazecalc's library by name, alias or maker. Use i.”
“Use “get_material”: One material from Glazecalc's library: its oxides, loss on ignition, whether it is discontinued and what replaces it, where it is sold, haza.”
“Use “analyze_recipe”: Works out a glaze recipe's unity (Seger) formula, oxide groups, silica to alumina ratio, fired analysis, loss on ignition and calculated the.”
“Use “check_limits”: Checks a glaze recipe for what is past a recommended limit for its firing (too much boron or alkali, too little alumina, too little or too m.”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Glazecalc holds up.
gate scanned 33 tools on Oct 23, 2026. A few things are worth a look before you connect.
Operated by Glazecalc (glazecalcapp.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
This server only exposes public data — no account and no credentials are involved when you connect.
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
If Glazecalc adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Choose Glazecalc in the gate directory. No sign-in needed.
Glazecalc's tools are live in every AI client you've connected — with rules and logging built in.

https://glazecalcapp.com/mcpYes — Glazecalc operates its own remote MCP server at glazecalcapp.com. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
Add gate's gateway URL to your AI client once, then pick Glazecalc in the directory. No account or sign-in is needed. From then on, Glazecalc's tools are available in every client you've connected to gate.
No. Glazecalc runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Yes — you can get started with gate for free and connect Glazecalc in minutes. No credit card required.
Every server below works through the same gateway URL — connect once, add tools anytime.
