Gemini CLI X402-Broker Global A2A, MCP & x402 Super-Marketplace search_x402_mcp_marketplace
How to: Gemini CLI X402-Broker Global A2A, MCP & x402 Super-Marketplace search_x402_mcp_marketplace
Add X402-Broker Global A2A, MCP & x402 Super-Marketplace to Gemini CLI
-
01
Open ~/.gemini/settings.json and merge this in. Keep any servers already there.
{
"mcpServers": {
"x402-broker": {
"httpUrl": "https://x402broker.com/mcp"
}
}
}-
02
Save the file and restart Gemini CLI.
-
03
Ask for something search_x402_mcp_marketplace does. Gemini CLI lists the server's tools on connect and calls search_x402_mcp_marketplace itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that X402-Broker Global A2A, MCP & x402 Super-Marketplace's identifier in your config matches the one above exactly.
Gemini expands $VAR and ${VAR} inside env values, so a secret can live in your shell rather than this file. Gemini CLI docs
Same tool, other clients
This list was read from the server itself, by connecting to it and calling tools/list on 19 October 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.
