AI-native code editor with built-in MCP support.

Cursor reads MCP servers from a JSON file. Use aproject-levelfile for per-repo config, or aglobalfile for all workspaces.

Just provide the URL. Cursor will open a browser window for you to log in via OAuth.

{ "mcpServers": { "maindex": { "type": "streamableHttp", "url": "https://maindex.io/mcp" } } }

{ "mcpServers": { "maindex": { "type": "streamableHttp", "url": "https://maindex.io/mcp", "headers": { "X-API-Key": "YOUR_API_KEY" } } } }

Fully quit and reopen Cursor. MCP servers are loaded at startup. You can verify the connection underSettings → Tools & MCP.

OAuth requires a local browser. If you are using Claude Code over SSH, use the API Key method instead.

claude mcp add --transport http --header "X-API-Key: YOUR_API_KEY" maindex https://maindex.io/mcp

This saves to thelocalscope by default (current project). Add--scope userfor all projects, or--scope projectto commit a shared.mcp.json.

Recommended: Install the Maindex extension

If you prefer a manual MCP-only setup without the extension content, follow the steps below.

Just provide the URL. Gemini CLI will open a browser for you to log in via OAuth.

gemini mcp add --transport http maindex https://maindex.io/mcp

This saves to your project-level config at.gemini/settings.json. For global config, edit~/.gemini/settings.jsondirectly.

gemini mcp add --transport http --header "X-API-Key: YOUR_API_KEY" maindex https://maindex.io/mcp

{ "mcpServers": { "maindex": { "url": "https://maindex.io/mcp", "headers": { "X-API-Key": "YOUR_API_KEY" } } } }

hermes plugins install maindexapp/hermes-plugin

This installs the Expert plugin automatically (no MCP URL configuration needed).

echo "MAINDEX_API_KEY=your-key" >> ~/.hermes/.envhermes config set memory.provider maindex

Use the refresh button in the MCP Servers panel to verify the connection. Maindex tools will appear when you use the@prompt.

LM Studio reads MCP servers from a JSON file. Open it via the in-app MCP editor, or edit the file directly:

{ "mcpServers": { "maindex": { "url": "https://maindex.io/mcp", "headers": { "X-API-Key": "YOUR_API_KEY" } } } }

LM Studio auto-reloads when you savemcp.json. Make sure you are using a tool-capable model (Llama 3.1+, Mistral, Qwen 2.5, etc.) for MCP tools to appear.

Self-hosted web interface for Ollama and other backends.

Go toAdmin Settings → External Tools. Requires Open WebUIv0.6.31or later.

Enter the URL and selectOAuth 2.1as the auth type. Open WebUI will handle the OAuth flow automatically.
