Claude Desktop 402MCP.org — HTTP 402 & Agent Payment Registry search_402_solutions
How to: Claude Desktop 402MCP.org — HTTP 402 & Agent Payment Registry search_402_solutions
Add 402MCP.org — HTTP 402 & Agent Payment Registry to Claude Desktop
-
01
Open ~/Library/Application Support/Claude/claude_desktop_config.json and merge this in. Keep any servers already there.
{
"mcpServers": {
"registry": {
"command": "npx",
"args": [
"-y",
"mcp-remote",
"https://402mcp.org/api/v1/mcp"
]
}
}
}-
02
Save the file and restart Claude Desktop.
-
03
Ask for something search_402_solutions does. Claude Desktop lists the server's tools on connect and calls search_402_solutions itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that 402MCP.org — HTTP 402 & Agent Payment Registry's identifier in your config matches the one above exactly.
Claude Desktop has no remote transport in its config file, so this bridges through mcp-remote. Restart the app after saving. Claude Desktop docs
Set these first
402MCP.org — HTTP 402 & Agent Payment Registry will not start until these are set, so search_402_solutions never becomes available.

Same tool, other clients
This list was read from the server itself, by connecting to it and calling tools/list on 16 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.
