Can I query my internal documents directly using just conversational chat?

Yes. If your data is indexed in a Vectara corpus, simply ask your agent: `search the 'employee-handbook' corpus for remote work policies`. The agent uses the `queryTool` to pass your question to Vectara's semantic engine, effortlessly bringing back precisely matching paragraph citations instantly.

How do I remove outdated context files destroying the accuracy of my RAG model?

You don't need to rebuild APIs or use cURL. Tell your AI: `delete document ID 'doc-992a' from my Sales corpus`. It automatically formats the mutation and wipes the poisoned embedding from Vectara's nodes permanently, restoring high accuracy.

Will the RAG Chat tool provide accurate source citations?

Yes. When you instruct the agent to run `execute_rag_chat`, Vectara processes the query against its internal LLM and index, returning a synthesized natural language answer appended solidly with exact document citations, proving the AI isn't hallucinating facts.

Vectara + Claude Desktop FAQ

Common questions about integrating Vectara MCP Server with Claude Desktop.

How does Claude Desktop discover MCP tools?

When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.

What happens if the MCP server is temporarily unavailable?

Claude Desktop handles disconnections gracefully. if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.

Can I connect multiple MCP servers simultaneously?

Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.

Is there a limit on the number of tools per server?

Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.

Does Claude Desktop support Streamable HTTP transport?

Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL. Claude auto-negotiates the transport protocol.
