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