README

MetaSearchMCP

Open-source metasearch backend for MCP, AI agents, and LLM workflows.

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.

Positioning

MCP-first metasearch backend
Structured search API for AI pipelines
Multi-provider search orchestration with deduplication and fallback
Python FastAPI alternative to browser-first metasearch projects

Why It Exists

Most search aggregators are designed around browser UX: HTML pages, pagination, and interactive result cards. Agents and LLM workflows need a different contract: predictable JSON, stable field names, partial-failure tolerance, and provider-level execution metadata.

MetaSearchMCP is built for that machine-consumable workflow. The design is centered on search orchestration, normalized contracts, and MCP integration.

Core Features

Concurrent multi-provider aggregation
Unified result schema for web, academic, developer, and knowledge sources
Provider-level timeout isolation and partial-failure handling
Result deduplication across engines
Provider selection by explicit names or semantic tags such as web, academic, code, and google
Final result caps for agent-friendly payload sizing
HTTP API with OpenAPI docs
MCP server over stdio for Claude Desktop, Cline, Continue, and similar clients
Configurable provider allowlist via environment variables

Google Support

Google support now includes a direct scraper provider implemented inside this project.

The direct Google implementation uses browser-like requests, consent cookie handling, locale-aware query parameters, and resilient HTML result parsing. It is implemented locally in this repository.

Currently supported Google providers:

Provider	Env var	Notes
Direct Google	`ALLOW_UNSTABLE_PROVIDERS=true`	Primary path; HTML scraping, best effort, may be blocked from datacenter IPs
serpbase.dev	`SERPBASE_API_KEY`	Pay-per-use; typically cheaper for low-volume usage
serper.dev	`SERPER_API_KEY`	Includes a free tier, then pay-per-use

Provider priority for /search/google is now google first, then google_serpbase, then google_serper.
