MetaSearchMCP vs holaOS
MetaSearchMCP: MetaSearchMCP aggregates results from multiple search providers, normalizes them into a stable JSON schema, and exposes both an HTTP API and an MCP server for agent tooling. It is designed for machine-consumable workflows, featuring concurrent aggregation, deduplication, and provider selection. This provides a structured search API alternative to browser-first metasearch projects.; holaOS: holaOS is an agent environment built for long-horizon work, continuity, and self-evolution. It provides agents with a structured operating system including runtime, memory, tools, apps, and durable state, enabling them to operate continuously, evolve over time, and remain inspectable across different runs.
