CTX vs web-researcher-mcp

CTX: CTX is a local context runtime for OpenCode and AI coding agents. It reduces token waste by indexing repositories, storing reusable guidance as graph memory, and providing compact task packs, read-cache compression, command pruning, and a live right-sidebar dashboard. It integrates natively with OpenCode as a context layer without replacing the agent launcher.; web-researcher-mcp: web-researcher-mcp is a production-grade MCP server that provides AI assistants with web search, content extraction, and multi-source research capabilities. It features multiple specialized tools, pluggable search backends with automatic fallback, a 4-tier scraping pipeline, and search lenses for domain-focused research. Enterprise-ready with OAuth 2.1, rate limiting, and audit logging.
