API MCP Server
Give your AI the power to call any public API with your key kept safe, through one hosted MCP server you do not have to install or run. UniversalBench is the server: connect one URL and your AI gets API plus every other capability, with safety built in. Works with Claude, ChatGPT, Gemini, and any MCP-compatible AI.
You do not have to host a API MCP server
There are open source API MCP servers you can download, configure, and run yourself, one capability at a time. UniversalBench takes that off your plate. It is a hosted MCP server, so there is nothing to install, nothing to keep running, and the same single connection also covers databases, code, web search, GitHub, files, and more.
| Self hosted server | UniversalBench | |
|---|---|---|
| Setup | Download, configure, run it | Paste one URL |
| Maintenance | You keep it running | Hosted for you |
| Coverage | API only | API plus 20+ capabilities |
| Safety | You secure it | Guards built in |
| Credentials | Wired into config | Encrypted vault, never shown |
Set up the API MCP server in three steps
Connect the one MCP URL
Add the single UniversalBench MCP URL to your AI: Claude, ChatGPT, Gemini, or any MCP-compatible client. That one server carries this capability and every other.
Save your credential once
Get the API key for the service you are calling, then save it in your secret vault as API_TOKEN. It unlocks the matching capability automatically and is never shown again.
Ask in plain language
Ask for what you want. The work runs on the hosted server and only the result returns to your chat.
