Cursor x402 Toolbox verify_tx_multi_source
How to: Cursor x402 Toolbox verify_tx_multi_source
Add x402 Toolbox to Cursor
-
01
Open ~/.cursor/mcp.json and merge this in. Keep any servers already there.
{
"mcpServers": {
"x402-toolbox": {
"url": "https://lab.paidapis.net/mcp"
}
}
}-
02
Save the file and restart Cursor.
-
03
Ask for something verify_tx_multi_source does. Cursor lists the server's tools on connect and calls verify_tx_multi_source itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that x402 Toolbox's identifier in your config matches the one above exactly.
Use .cursor/mcp.json in a project root instead to scope it to that project. Cursor merges both. Cursor docs
Same tool, other clients
This list was read from the server itself, by connecting to it and calling tools/list on 24 September 2026. It is what
the server actually exposes, not what its listing claims.
Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
