User Agent Generator Skill

What this skill does

Let your agent produce realistic user-agent strings. Call it as an MCP tool to generate desktop, mobile or tablet UAs with parsed browser and OS. 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

One toggle, a new capability

Enable User Agent Generator and your app or agent can generate user agent on demand — no SDK, no endpoint wiring. It answers over MCP or REST using the same key as every other skill.

A tool agents call themselves

Over MCP, User Agent Generator appears to your model as the useragentgenerator tool it invokes whenever a task needs it — you don't write the glue, the agent reaches for it.

REST from any backend

Prefer to call it directly? Any language that can send a GET can hit User Agent Generator to generate user agent inline in your own server-side code.

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.

useragentgenerator

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/useragentgenerator

Ask your agent

“Enable User Agent Generator and ask your agent to generate user agent.”
“Generate a batch of realistic sample values.”

How to connect it over MCP or REST.

How do I add User Agent Generator to my app or agent?

Enable the User Agent Generator Skill on VerveKit, then reach it two ways with the same key: over MCP (it appears to your agent as the useragentgenerator 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 generate user agent — 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 User Agent Generator appears as a standard tool with nothing skill-specific to integrate.

How many credits does a User Agent Generator 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 User Agent Generator is available immediately.

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

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