Before you call either
Qdrant API + MCP
- Create payload indexes on the fields you filter on, or filtered search slows on large collections
- Use
/points/querywithprefetchto fuse dense and BM25 results - Pass
wait=trueon upserts when the next step reads its own writes - On 429, wait for the
Retry-Afterseconds before retrying - Set
with_vector=falseunless the task needs vectors, since they dominate response size
Upstash Vector API + MCP
- Connect to mcp.upstash.com/mcp for Vector tools.
npx @upstash/mcp-serverhas none - Create the index with an embedding model if the agent works in text; then
query-dataandupsert-datatake strings - Give retrieval-only agents the index's read-only token, not the full one
- Filters use a SQL-like string (
genre = 'fiction' AND year > 2020) in thefilterfield - Ignore the FAQ line saying hybrid isn't supported. Pass
queryModeHYBRID, DENSE or SPARSE on hybrid indexes
