MetaSearchMCP vs pctx

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.; pctx: pctx sits between AI agents and MCP servers, aggregating multiple upstream MCP servers, handling authentication, and exposing tools through a unified Code Mode interface. It replaces sequential tool calling with code execution, resulting in significant token reduction. It supports multiple installation methods and provides Python SDK for agent development.
