Before you call either

Pinecone API + MCP

  1. Send X-Pinecone-Api-Version: 2026-07 on every call. Without it you get the oldest supported version
  2. Queries go to the index host from describe_index, not to api.pinecone.io
  3. Wait a few seconds and retry when fresh upserts don't show up in search
  4. Back off exponentially on 429. There's no Retry-After header
  5. Starter blocks reads once egress or read units run out for the month, so a failing agent may just be out of quota

Upstash Vector API + MCP

  1. Connect to mcp.upstash.com/mcp for Vector tools. npx @upstash/mcp-server has none
  2. Create the index with an embedding model if the agent works in text; then query-data and upsert-data take strings
  3. Give retrieval-only agents the index's read-only token, not the full one
  4. Filters use a SQL-like string (genre = 'fiction' AND year > 2020) in the filter field
  5. Ignore the FAQ line saying hybrid isn't supported. Pass queryMode HYBRID, DENSE or SPARSE on hybrid indexes
