Works with
- Claude Code
- Codex
- Cursor
- VS Code
- Copilot CLI
From the marketplaces that list it and the MCP transport it declares, as each client documents them. We do not test plugins.
Connect
Commands and configs built only from what its marketplaces declare. We do not run them for you and do not test plugins.
As a local MCP server: npm package
Built from what Official MCP Registry declares.
claude mcp add --env "SCX_STATE_PASSPHRASE=<YOUR_SCX_STATE_PASSPHRASE>" --transport stdio stablecoinx-mcp -- npx -y @stablecoinx/mcp[mcp_servers.stablecoinx-mcp]
command = "npx"
args = ["-y", "@stablecoinx/mcp"]
[mcp_servers.stablecoinx-mcp.env]
SCX_STATE_PASSPHRASE = "<YOUR_SCX_STATE_PASSPHRASE>"{
"mcpServers": {
"stablecoinx-mcp": {
"command": "npx",
"args": [
"-y",
"@stablecoinx/mcp"
],
"env": {
"SCX_STATE_PASSPHRASE": "<YOUR_SCX_STATE_PASSPHRASE>"
}
}
}
}Replace the values in angle brackets with your own. We show the names of the settings, never values.
Optional settings it also lists: SCX_STATE_DIR.
We do not store launch arguments. If the server needs any, its own documentation names them.

Is this your plugin?
Add it to your projects and prove you maintain it with a file in its repository, a file on your domain or a DNS record. You get alerts when a marketplace lists it, drops it, changes its verified mark or what it asks for, and its remote endpoint goes on monitoring as a web service.
Data comes from the Official MCP Registry (registry.modelcontextprotocol.io), CC0 1.0. Figures come from our own regular passes over the marketplaces, last read on . We publish no contact details for plugin publishers.
