VS Code crosscheck skillcheck_lookup
How to: VS Code crosscheck skillcheck_lookup
Add crosscheck to VS Code
-
01
Open .vscode/mcp.json and merge this in. Keep any servers already there.
{
"servers": {
"crosscheck": {
"type": "http",
"url": "https://crosscheckapi.com/mcp"
}
}
}-
02
Save the file and restart VS Code.
-
03
Ask for something skillcheck_lookup does. VS Code lists the server's tools on connect and calls skillcheck_lookup itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that crosscheck's identifier in your config matches the one above exactly.
Requires agent mode. MCP: Open User Configuration puts the same block in every workspace. VS Code docs
Set these first
crosscheck will not start until these are set, so skillcheck_lookup never becomes available.

Same tool, other clients
This list was read from the server itself, by connecting to it and calling tools/list on 25 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.
