How to: Cline FetchSandbox verify_behavior
Add FetchSandbox to Cline
-
01
Open ~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json and merge this in. Keep any servers already there.
{
"mcpServers": {
"mcp": {
"url": "https://fetchsandbox.com/mcp/v1"
}
}
}-
02
Save the file and restart Cline.
-
03
Ask for something verify_behavior does. Cline lists the server's tools on connect and calls verify_behavior itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that FetchSandbox's identifier in your config matches the one above exactly.
Cline's MCP Servers pane edits this file for you if you would rather not find it. Cline docs
Set these first
FetchSandbox will not start until these are set, so verify_behavior never becomes available.

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.
