LlamaIndex

Verification notes: Correction this pass: the license hedge from the prior review is resolved — LlamaIndex's core Python framework (run-llama/llama_index) and TypeScript port (run-llama/LlamaIndexTS) are both confirmed MIT licensed. The open-source library is free to run locally or self-hosted; LlamaCloud (managed parsing, extraction, indexing, agent deployment) is a separate paid commercial layer on top of it. MCP integration support is unchanged from the prior pass. Re-checked this pass: third-party sample repositories and tutorials (e.g. A2A Protocol's own samples directory) show LlamaIndex Workflows being wired up to A2A servers, but that reflects the broader A2A ecosystem building adapters for popular frameworks, not LlamaIndex's own documentation shipping native A2A support — no official LlamaIndex docs page dedicated to A2A was found. The a2a flag stays false rather than being inferred from ecosystem samples.
