Watch out for

• It can create indexes and overwrite records

  create-document-index and create-index-for-model create indexes. upsert-documents and upsert-records replace any record with the same ID. Use a key for a dev project, not production. github.com

• The assistant reports its model name to Pinecone

  Every database tool has optional fields where the assistant states its provider and model, and the server passes them to Pinecone, which says it uses them for usage analytics. The assistant is told not to ask you for them. github.com

• Docs search goes to a Pinecone-hosted service

  search-docs sends your question to a Pinecone-run docs assistant, with or without an API key. github.com

• No tool deletes an index or records

  The source registers 12 tools and none of them is a delete tool. github.com
