Description

Vectara MCP exposes Vectara search and generation capabilities over the MCP protocol, supporting HTTP, SSE, and STDIO transports for integration with MCP clients (e.g., Claude Desktop). It offers tools for RAG queries with generation, semantic search, hallucination detection & correction, and factual-consistency evaluation, with built-in authentication and security recommendations for production. The server is configurable via CLI flags and environment variables and is intended for both local development (STDIO) and production deployments (HTTP/SSE behind TLS).
