firefox-devtools-mcp vs trace-mcp

firefox-devtools-mcp: Firefox DevTools MCP is a Model Context Protocol server that automates Firefox using WebDriver BiDi through Selenium. It enables AI assistants like Claude to control browser actions such as navigation, screenshots, and network monitoring. It integrates with various MCP clients including Claude Code, Cursor, and Cline.; trace-mcp: trace-mcp is a framework-aware code intelligence MCP server that builds cross-language dependency graphs from source code. It enables AI agents to understand framework-specific relationships, track request flows, analyze change impact, and remember past decisions across sessions, significantly reducing token usage.
