As a local MCP server: npm package
Built from what Official MCP Registry declares.
claude mcp add --env "CONFIGCAT_API_PASS=<YOUR_CONFIGCAT_API_PASS>" --env "CONFIGCAT_API_USER=<YOUR_CONFIGCAT_API_USER>" --transport stdio io-github-configcat-mcp-server -- npx -y @configcat/mcp-server[mcp_servers.io-github-configcat-mcp-server]
command = "npx"
args = ["-y", "@configcat/mcp-server"]
[mcp_servers.io-github-configcat-mcp-server.env]
CONFIGCAT_API_PASS = "<YOUR_CONFIGCAT_API_PASS>"
CONFIGCAT_API_USER = "<YOUR_CONFIGCAT_API_USER>"{
"mcpServers": {
"io-github-configcat-mcp-server": {
"command": "npx",
"args": [
"-y",
"@configcat/mcp-server"
],
"env": {
"CONFIGCAT_API_PASS": "<YOUR_CONFIGCAT_API_PASS>",
"CONFIGCAT_API_USER": "<YOUR_CONFIGCAT_API_USER>"
}
}
}
}Replace the values in angle brackets with your own. We show the names of the settings, never values.
Optional settings it also lists: CONFIGCAT_BASE_URL.
We do not store launch arguments. If the server needs any, its own documentation names them.

Found by meaning, not by shared code or a shared repository: similar plugins stay separate products, and this is not a review or a recommendation.
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.
