VS Code crosscheck check

How to: VS Code crosscheck check

client:VS Code transport:streamable-http tool:check

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 check does. VS Code lists the server's tools on connect and calls check 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 check never becomes available.

CROSSCHECK_WALLET_KEY
CROSSCHECK_MAX_USD
CROSSCHECK_NETWORKS

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.
