semble vs pubcrawl

semble: Semble is a high-performance code search library designed for AI agents, providing instant access to precise code snippets. It offers significantly faster indexing and querying compared to transformer models, achieving 99% of their retrieval quality while running entirely on CPU without external dependencies.; pubcrawl: PubCrawl is an MCP server that gives LLM clients structured access to biomedical literature databases including PubMed, FDA drug labeling, UK medicines data, and ClinicalTrials.gov. Built by PharmaTools.AI, it enables AI assistants to perform peer-reviewed literature searches, retrieve clinical trial data, and access regulatory drug information through a unified interface.
