Verification notes: Re-checked this pass. Core framework remains Apache 2.0, confirmed directly via Mastra's own 'Mastra is now Apache 2.0 licensed' announcement and the repository LICENSE.md; enterprise features stay separately licensed as source-available (Mastra Enterprise License). The project has grown to 24,000+ GitHub stars, with the latest core release (@mastra/core 1.35.0) shipping in May 2026. No change to open-source status or MCP support. Re-checked again this pass (September 2026): no change to Apache 2.0 core licensing or MCP support; the project continues active weekly releases across its component packages.
