Open source SDK and infra for MCP servers & agents
mcp-use is the open-source devtools and cloud infrastructure to help dev teams quickly build and deploy custom AI agents with MCP servers. Our SDK has over 5,000 GitHub stars, 100k downloads, and is trusted by engineers at NASA, Cisco, NVIDIA, etc...
mcp-use Cloud provides built-in analytics, session replay, error tracking, and alerts. Developers see traffic, tool-call volume, latency, and can replay user conversations end-to-end to identify issues before users report them.
mcp-use provides a fullstack MCP framework with one-command deployment to Manufact Cloud, auto-scaling, observability, and branch previews. Developers scaffold complete MCP servers and React-based apps in under 60 seconds and deploy via git push, eliminating manual DevOps work.
mcp-use's MCPClient and MCPAgent implementations allow developers to aggregate multiple MCP servers through one endpoint, supporting OpenAI, Anthropic, Google, and LangChain LLMs. This enables agents to discover and execute tools across distributed servers without friction.
mcp-use automates marketplace submission by generating logos, copy, and screenshots. It provides submission checklists and embedded chat widgets, reducing the barrier to reaching users across ChatGPT, Claude, and other MCP clients from a single codebase.
The built-in Cloud Inspector lets developers test MCP servers against GPT, Claude, and Gemini models, swap models mid-session, inspect JSON-RPC calls, and run automatic evaluations—all from a browser without local setup.
