Ring Size Converter Skill

What this skill does

Let your agent convert ring sizes. Call it as an MCP tool to translate any size across US, UK, EU, JP and more, or from a diameter in mm. You switch it on with a single toggle — no SDK and no endpoint wiring — and it answers over MCP or REST using the same key as every other skill.

Ways to use it

Trusted facts in one call

Enable Ring Size Converter and your app can convert ring size from a live source instead of shipping a lookup table you have to keep current.

A tool agents call for ground truth

Over MCP, your model calls ringsizeconverter to fetch a reference value at the moment it needs it, rather than recalling it imperfectly.

REST from any stack

Call Ring Size Converter directly to convert ring size inline, one key across every skill.

Use it in your app

Once enabled, this skill is reachable two ways — pick whichever fits how you build. Both use the same key.

For AI agentsMCP

It appears to your model as a callable tool. No extra code — the agent invokes it when a task needs it.

ringsizeconverter

For apps & backendsREST

Call it from your server with one request and your key. Node, Python, Go — anything that can send a GET.

GET /v1/ringsizeconverter

Ask your agent

“Enable Ring Size Converter and ask your agent to convert ring size.”
“Use the Ring Size Converter skill for me.”

How to connect it over MCP or REST.

How do I add Ring Size Converter to my app or agent?

Enable the Ring Size Converter Skill on VerveKit, then reach it two ways with the same key: over MCP (it appears to your agent as the ringsizeconverter tool) or over REST (call it from any backend). No SDK to install and no endpoint to wire.

MCP or REST — which should I use?

Both work off one key. Use MCP when an AI agent should decide when to convert ring size — the skill shows up as a callable tool. Use REST when your own server-side code should call it directly. Many apps use both.

Which agents and frameworks does it work with?

Any MCP client — Claude, Cursor, LangChain, and custom agents all speak the Model Context Protocol, so Ring Size Converter appears as a standard tool with nothing skill-specific to integrate.

How many credits does a Ring Size Converter call cost?

Each call costs 1 credit. Every skill rides the same key and the same connection, so enabling more skills doesn't add more integrations to manage.

Do I need to install anything?

No SDK and no endpoint wiring — enabling the skill is a toggle. You point your agent at the VerveKit MCP endpoint (or call REST) and Ring Size Converter is available immediately.

Where does the data come from, and what shows on my bill?

VerveKit runs on APIVerve, our production data engine; Ring Size Converter is one of 300+ skills on the same key. Invoices and card statements show APIVERVE.
