Authentication
Per-user OAuth in one call. Your Zendesk MCP server gets session-scoped tokens with zero credentials stored on your infra.
Agent Auth →Security
Every Zendesk tool response scanned for prompt injection in milliseconds — 88.7% accuracy, all running on CPU.
Prompt Injection Defense →Performance
Free up to 96% of your agent's context window to enhance reasoning and reduce cost, on every Zendesk call.
Tools Discovery →A Zendesk MCP server lets AI agents read and write Zendesk data through the Model Context Protocol — Anthropic's open standard for connecting LLMs to external tools. StackOne's Zendesk MCP server ships with 43 pre-built actions, fully extensible via the Connector Builder — plus managed authentication, prompt injection defense, and optimized agent context. Connect it from MCP clients like Claude Desktop, Cursor, and VS Code, or from agent frameworks like OpenAI Agents SDK, LangChain, and Vercel AI SDK.
