fastmcp vs deepseek-pp

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.; deepseek-pp: DeepSeek++ is a browser extension for Chrome, Edge, and Firefox that injects native-style tool calling, an MCP tool system, long-term memory, skill presets, and automated task scheduling into the DeepSeek web interface. It intercepts the SSE response stream in real time to execute tool calls transparently, giving DeepSeek persistent cross-session memory and agent-like automation without API access.
