A JobAdder MCP server lets AI agents read and write JobAdder data through the Model Context Protocol — Anthropic's open standard for connecting LLMs to external tools. StackOne's JobAdder MCP server ships with 246 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 JobAdder MCP Tools
Every action from JobAdder's API, ready for your agent. Create, read, update, and delete — scoped to exactly what you need.
