Announcing StackOne Defender: leading open-source prompt injection guard for your agent • Read More →
Production-ready X (Twitter) MCP server with 55 extensible actions — plus built-in authentication, security, and optimized execution.
Coverage
Create, read, update, and delete across X (Twitter) — and extend your agent's capabilities with custom actions.
Authentication
Per-user OAuth in one call. Your X (Twitter) MCP server gets session-scoped tokens with zero credentials stored on your infra.
Agent Auth →Security
Every X (Twitter) 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 X (Twitter) call.
Tools Discovery →A X (Twitter) MCP server lets AI agents read and write X (Twitter) data through the Model Context Protocol — Anthropic's open standard for connecting LLMs to external tools. StackOne's X (Twitter) MCP server ships with 55 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.
Every action from X (Twitter)'s API, ready for your agent. Create, read, update, and delete — scoped to exactly what you need.
