Tools Discovery →What is the Envoy MCP Server?
A Envoy MCP server lets AI agents read and write Envoy data through the Model Context Protocol — Anthropic's open standard for connecting LLMs to external tools. StackOne's Envoy MCP server ships with 49 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.
All Envoy MCP Tools
Every action from Envoy's API, ready for your agent. Create, read, update, and delete — scoped to exactly what you need.
