kernel-mcp-server vs plasmate

kernel-mcp-server: Kernel MCP Server bridges AI assistants with the Kernel platform, enabling deployment of apps, headless Chromium browser automation, monitoring, and more. It supports OAuth 2.0 authentication and is fully managed with an open-source codebase. Users can use the cloud-hosted endpoint or run locally.; plasmate: Plasmate compiles HTML into a Semantic Object Model (SOM), a structured representation that LLMs can reason about directly. It runs JavaScript via V8, supports Puppeteer via CDP, and produces output that is 10-800x smaller than raw HTML. It is purpose-built for AI agent pipelines, with MCP, Vercel AI SDK integrations, and over 60 ecosystem integrations.
