fastmcp: FastMCP is a standard framework for building Model Context Protocol (MCP) applications, which connect LLMs to tools and data. It simplifies the process by automatically generating schemas, validation, and documentation for tools, and managing transport negotiation and authentication for server connections. FastMCP offers a comprehensive solution for developing, deploying, and scaling MCP-powered systems.; qveris-agent-toolkit: QVeris Agent Toolkit is the open-source client layer for the QVeris capability routing network, giving agents access to 10,000+ real-world capabilities across 15+ categories. It ships a CLI, MCP server, Python SDK, and REST API docs so agents can discover, inspect, invoke, and audit tools through a single protocol. Available for Cursor, Claude Code, OpenCode, and OpenClaw-style skill agents.
