### Key Gotchas

1. **Response keys are in GERMAN** — `suchbegriff` (search term), `gefunden` (found), `varianten` (variants), `organismus` (organism), `wissenschaftlicher_name` (scientific name), `zusammenfassung` (summary), `fehler` (error), `laenge` (length), `autoren` (authors), `gesamt_treffer` (total hits)
2. **`search_proteins` returns 400 from UniProt** — the query format `(insulin) AND (organism_name:human)` triggers UniProt API v2 rejection; direct protein lookups via `get_protein_details` work fine
3. **Network-bound latency** — all calls 1.8-6.2s due to round-trips to NCBI/UniProt APIs
4. **NCBI rate limiting** — server uses `tool=bioinformatics-mcp-server&email=agent@aiagentkarl.com` for NCBI requests (3 req/sec without API key)
5. **ClinVar significance filter** — valid values include "pathogenic", omitting returns all significance levels
6. **PubMed sort** — accepts "relevance" and date-based sorting; `years_back` filters by publication date
7. **Sequence retrieval** — `database` accepts "nucleotide" or "protein"; `sequence_type` defaults to "fasta"
8. **Gene details include summary** — full text functional description from NCBI Gene (key:
