Tools Discovery →What is the Workato MCP Server?
A Workato MCP server lets AI agents read and write Workato data through the Model Context Protocol, Anthropic's open standard for connecting LLMs to external tools. StackOne's Workato MCP server ships with 25 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.
