Can my agent help improve search relevance by posting signals?

Yes. Use the `lw.post_signal` tool to feed conversion or click events into Fusion. These signals are used by the machine learning models to identify high-value results and re-rank them for better precision automatically.

How do I check which AI models are active in my query pipeline?

The `lw.list_query_profiles` tool retrieves all defined profiles in your gateway. Your agent will expose the exact AI models and routing configurations assigned to each profile, helping you audit your search logic.

Can I index new documents directly through a conversation?

Absolutely. Use the `lw.index_documents` tool by providing a JSON array of your data. Your agent will synchronize these new mappings into your Fusion collection, making the content queryable instantly.

Lucidworks Fusion (AI Search & Discovery) + VS Code Copilot FAQ

Common questions about integrating Lucidworks Fusion (AI Search & Discovery) MCP Server with VS Code Copilot.

Which VS Code version supports MCP?

MCP support requires VS Code 1.99 or later with the GitHub Copilot extension. Ensure both are updated to the latest version. Older versions of Copilot may not expose the Agent mode toggle.

How do I switch to Agent mode?

Open the Copilot Chat panel and look for two mode options: "Ask" and "Agent". Click "Agent" to enable autonomous tool calling. In Ask mode, Copilot provides conversational answers but cannot invoke MCP tools.

Can I restrict which MCP tools Copilot can access?

Yes. VS Code shows a tool consent dialog before any MCP tool is invoked for the first time. You can also configure tool access policies at the organization level through GitHub Copilot settings.

Does MCP work in VS Code Remote or Codespaces?

Yes. MCP servers configured via .vscode/mcp.json work in Remote SSH, WSL, and GitHub Codespaces environments. The MCP connection is established from the remote host, so ensure the server URL is accessible from that environment.
