{
"mcpServers": {
"stringdb": {
"url": "https://mcp.string-db.org/"
}
}
}A green dot in Settings → MCP means it connected.

{
"servers": {
"stringdb": {

Add https://mcp.string-db.org/ as a custom connector under Settings → Connectors in Claude Desktop or claude.ai, or run "claude mcp add --transport http string-db https://mcp.string-db.org/" in Claude Code.
Do I need to install anything to use the STRING MCP server?
No. It is a remote server hosted by STRING, so your MCP client connects to it over HTTP. You authenticate with the vendor rather than installing a package.
