Pick IDE Index MCP Server if you want a hosted/remote server with nothing to install, and you want zero-setup with no API key.

Pick Context7 MCP Server if you want the official, vendor-maintained server, and you prefer the more popular, battle-tested option.

Add IDE Index MCP Server

Install / run

claude mcp add --transport http --scope user intellij-index http://127.0.0.1:29170/index-mcp/streamable-http

{
  "mcpServers": {
    "ide-index-mcp-server": {
      "command": "npx",
      "args": [
        "-y",

        "http://127.0.0.1:29170/index-mcp/streamable-http"
      ]
    }
  }

Claude Desktop connects to remote servers through the `mcp-remote` proxy (installed on first run via npx). Restart Claude Desktop after saving.
