MCP for Cursor
Give Cursor the power to act through MCP. UniversalBench is a hosted MCP server, so instead of installing and running a server per tool, you connect one URL in Cursor and it can run code, search the live web, read and write databases, commit to GitHub, work with files, and more, with safety built in.
Add the MCP server to Cursor
Open your mcp.json
Open or create ~/.cursor/mcp.json for all projects, or .cursor/mcp.json inside one project.
Add the UniversalBench server
Add the entry below with your MCP URL.
Save the file
Cursor picks up the server automatically.
Ask in chat
Ask Cursor to use it. It can run code, query databases, search the web, commit to GitHub, and more.
Your secrets live in an encrypted secret vault
When a capability needs a credential, a GitHub token, a database URL, an API key, you save it once in your secret vault. You enter the secret name on the left and the secret value on the right, then save. Cursor never sees the value, it is never shown in the chat, and the matching capability unlocks automatically.
What Cursor can do once connected

Slack

One hosted server beats wiring up many
Most MCP servers do one job and you run each one yourself. With UniversalBench you point Cursor at a single hosted URL and every capability is there, so there is nothing to install, nothing to keep running, and your credentials sit in an encrypted secret vault instead of scattered across config files.
| Many self hosted servers | UniversalBench | |
|---|---|---|
| Setup in Cursor | One entry per tool | One URL |
| Maintenance | You keep each running | Hosted for you |
| Coverage | One tool per server | 20+ capabilities |
| Credentials | In config files | Encrypted vault, never shown |
