Use case · Cursor
All your MCP tools in Cursor, from one endpoint.
Instead of a growing wall of servers in ~/.cursor/mcp.json, add a single onemcp portal. Cursor's agent gets every tool you've curated — with none of the per-request token overhead.
Connect Cursor in three steps
- 1
Curate a portal
Add the MCP servers you want into a onemcp portal and authenticate them once.
- 2
One mcp.json entry
Drop your portal URL into ~/.cursor/mcp.json — a single server instead of a dozen.
- 3
Code and let it call
Cursor's agent searches, describes, and executes your tools through Code Mode.
Add to ~/.cursor/mcp.json:
onemcp
{
"mcpServers": {
"onemcp": {
"url": "https://portal.onemcp.dev/mcp"
}
}
}Why point Cursor at onemcp
No more config sprawl
Manage servers in the portal, not in every teammate's mcp.json.
Secrets never touch the repo
Upstream OAuth and tokens stay in the portal, out of your project config.
Faster, cheaper prompts
~90% smaller tool overhead means Cursor keeps its context for your code.
One line in mcp.json. Every tool in Cursor.
Create a portal, paste the URL into Cursor, and start building.
