OpenRouter MCP Upgrade: Model Query Context Reduced by 96%, Installation Can Be Completed by Agents Reading It Themselves

OpenRouter announced an MCP upgrade, allowing users to directly call 600+ models, the Decisions API, and image, speech, and video generation within agent conversations. Model query responses have been reduced from about 1 MB (about 250k tokens) to 38 KB with pagination, a 96% reduction; video tasks are initiated by the agent and then retrieve a link, no longer stuffing raw bytes into the context. The installation method has changed to having the agent read the installation page and complete it on its own; the official statement says that in its tests, Claude Code improved from 5/8 tasks to 8/8.
