Performance
Max Agent Context. Min Cost.
Free up to 96% of your agent's context window to enhance reasoning and reduce cost, on every Lucid call.
Tools Discovery →What is the Lucid MCP Server?
A Lucid MCP server lets AI agents read and write Lucid data through the Model Context Protocol — Anthropic's open standard for connecting LLMs to external tools. StackOne's Lucid MCP server ships with 61 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 Lucid MCP Tools
Every action from Lucid's API, ready for your agent. Create, read, update, and delete — scoped to exactly what you need.
