Mastra
An open-source agent framework for TypeScript projects, using input examples to raise tool-calling hit rates and letting authenticated MCP tool chains reach real business systems rather than demos.
Mastra is an open-source agent framework for TypeScript developers, and release 1.10.0 concentrates on tool calling and runtime stability. Tool definitions now accept inputExamples, so sample inputs show the model what a correct call looks like and lift hit rates in complex workflows. The MCP client can forward cookies or bearer tokens through the request context, letting authenticated tool chains reach real business systems.
