MetaSearchMCP vs semble
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.; semble: Semble is a high-performance code search library designed for AI agents, providing instant access to precise code snippets. It offers significantly faster indexing and querying compared to transformer models, achieving 99% of their retrieval quality while running entirely on CPU without external dependencies.
