What is the Vectara MCP Server?
Connect your Vectara environment to any AI agent to unlock enterprise-grade Retrieval-Augmented Generation (RAG) and semantic search directly inside your conversational IDE or workspace.
What you can do
- Semantic Search — Query your indexed private corpora naturally and return highly relevant, grounded documents without traditional keyword matching limitations.
- Conversational RAG — Execute fully-fledged interactive chats leveraging Vectara's backend to provide detailed, cited answers strictly based on your secure documents.
- Corpus Management — List all available data corpora, retrieve unique keys, and discover the shape of your indexed data environment on the fly.
- Document Auditing — Monitor specific document indexes within a corpus, verify correct ingestions, or permanently delete obsolete files avoiding polluted search results.
How it works
- Subscribe to this server
- Enter your Vectara API Key and Customer ID
- Start retrieving knowledge from Claude, Cursor, or any MCP-compatible client
Your AI agent becomes an elite cognitive search gateway to all your internal data.
Who is this for?
- Software Engineers — debug RAG implementation challenges by directly testing
queryresponses via chat instead of writing disposable test scripts. - Data Engineers — securely remove stale database context arrays manually inserted into Vectara via quick conversational text commands.
- Product Leads — ask questions against internal product manuals stored as a Vectara corpus without waiting for the frontend UI development.
- Technical Writers — locate specific passages traversing across thousands of embedded documents effortlessly leveraging contextual semantic queries.

Frequently asked questions
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How do I remove outdated context files destroying the accuracy of my RAG model?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.
How does Google ADK connect to MCP servers?
Import the MCP toolset class and pass the server URL. ADK discovers and registers all tools automatically, making them available to your agent's tool-use loop.
Can ADK agents use multiple MCP servers?
Yes. Declare multiple MCP tool providers in your agent configuration. ADK merges all tool schemas and the agent can call tools from any server in a single turn.
Which Gemini models work best with MCP tools?
Gemini 2.0 Flash and Pro models both support function calling required for MCP tools. Flash is recommended for latency-sensitive use cases, Pro for complex reasoning.
