A Keeper MCP server lets AI agents read and write Keeper data through the Model Context Protocol, Anthropic's open standard for connecting LLMs to external tools. StackOne's Keeper MCP server ships with 27 pre-built actions, fully extensible via the Connector Builder, plus managed authentication, prompt injection defense, observability, and agent execution runtime. Connect it from MCP clients like Claude Desktop, Claude Code, Cursor, Goose, and VS Code, or from agent frameworks like OpenAI Agents SDK, LangChain, and Vercel AI SDK.
