Optimizely ships remote MCP for experimentation data

Optimizely released an official remote MCP server in early May 2026, letting anyone with Optimizely credentials point Claude, Cursor, or ChatGPT at their experimentation data through OAuth. Endpoint is exp.mcp.opal.optimizely.com/mcp. The server can query projects, list experiments, inspect performance, and modify traffic splits, but stops short of publishing live changes; you still need the UI for the final Publish click. Notable as one of the cleaner first-party MCPs in the experimentation/CRO space, which has been slow to adopt the protocol.
