Watsonx

expertvagabond/watsonx-mcp-server

Connects Claude to IBM watsonx.ai foundation models including Granite, Llama, and Mistral for text generation, chat, and embeddings. Exposes four tools: watsonx_generate for text completion, watsonx_chat for conversations, watsonx_embeddings for generating vectors, and watsonx_list_models to see what's available. Requires an IBM Cloud API key and either a deployment space ID or project ID. Useful when you need IBM's enterprise models for batch inference, want specialized Granite capabilities, or need to generate embeddings for RAG pipelines while keeping Claude as your primary reasoning agent. Includes command line tools for document analysis, semantic search, and batch processing across large document sets.
