Tools Discovery →What is the Envi MCP Server?
A Envi MCP server lets AI agents read and write Envi data through the Model Context Protocol — Anthropic's open standard for connecting LLMs to external tools. StackOne's Envi MCP server ships with 100 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.

Every action from Envi's API, ready for your agent. Create, read, update, and delete — scoped to exactly what you need.
