Tools Discovery →What is the Tacton MCP Server?
A Tacton MCP server lets AI agents read and write Tacton data through the Model Context Protocol, Anthropic's open standard for connecting LLMs to external tools. StackOne's Tacton MCP server ships with 51 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 Tacton MCP Tools
Every StackOne action for Tacton, ready for your agent. Read, write, delete and run operations, scoped to exactly what you need.
