What fits

agent-search-mcpstrong · 93

Positioned as a free-first web search MCP server that returns compact, agent-friendly evidence without requiring paid search API keys, making it directly usable by AI agents that need broader web sources.

Best for: Developers building or extending AI agents that need a zero-cost web-search backend.

AgentSearchstrong · 89

A self-hosted search API and MCP server bundling SearXNG with layered content extraction and optional browser rendering, explicitly offered as a no-third-party-key alternative for AI agents.

Best for: Teams or developers who want a drop-in, open search API for agents that avoids per-query fees.

Open Research ANAstrong · 82

An open-source, agent-native research canvas that performs real-time search with human-in-the-loop steering, so an agent's research and synthesis can be corrected and guided mid-process rather than only after the fact.

Best for: Researchers and power users who want interactive steering of an agent's research and synthesis.

CrawlLamastrong · 80

A local research agent integrating web search with RAG-style reasoning and multi-hop research, designed for extensible, multi-step agent workflows and OSINT-style evidence gathering.

Best for: Developers who want a local agent that chains web searches and reasoning steps for deeper multi-step research.

Scientific Agent Skillsstrong · 78

A large, open collection of ready-to-use research skills and database connectors that agents can call to access many public scientific and financial databases, making agents immediately more capable at domain research.

Best for: Teams and developers who want prebuilt research skills and connectors to plug into agents, especially for scientific data sources.

Partly fits

iloveAgentspartial · 60

Browser-run hub for focused agents that helps run many agents in-browser but is not primarily a web-retrieval backend.

Won’t cover: Acts as an in-browser agent runner rather than a dedicated web-search or scraping API your agent calls for evidence.

Agent-yespartial · 58

Automates running and retrying coding agents unattended but focuses on orchestration rather than providing broader web search evidence.

Won’t cover: Manages and retries agent runs but does not itself supply web search or structured evidence from external sources.

AI Freepartial · 56

Local client that unifies free web chats into a developer workflow, useful for local experimentation but not a dedicated web-retrieval or crawling backend.

Won’t cover: Provides local access and CLI/IDE integration to existing chat providers rather than a free web-crawling or extraction service for agents.

Guanlanpartial · 55

Specialized at reading and organizing Chinese-internet sources for agents, making it highly relevant for Chinese-language research but narrower in audience.

Won’t cover: Focused on Chinese-internet research rather than broad, multi-language web coverage.
