IntelliSearch V3.1: Unifying Search, Empowering Action

IntelliSearch (SJTU AI-Intelligent Search) originated as a specialized search agent powered by the Model Context Protocol. Today, it has evolved into a lightweight, decoupled, and highly extensible Agentic Infrastructure. By integrating advanced agent topologies, multi-dimensional memory systems, and dynamic tool scheduling, IntelliSearch provides a foundational ecosystem that balances developer-friendly ease of use with industrial-grade flexibility.

Important

We are delighted to announce the second agent release of IntelliSearch agent series: IntelliSearch-V3.1 is released and open-sourced! See Project Pages for more fancy demos and features!

IntelliSearch V3.1

IntelliSearch V3.1 has achieved an all-round comprehensive upgrade, significantly expanding the boundaries of language models. New features including:

• 🛠️ IntelliSearch-Toolkit: We introduce IntelliSearch-Toolkit, a high quality toolkit including multi-source multi-domain SEARCH tools and safe OPERATE tools with environment interactions. It also supports extensible MCP-based tools for customization and advanced workflows.

  • Search Tools: Multi-source, multi-domain search engines
    • Web Search (Google Search, Zhipu AI Search, Web Content Parser)
    • GitHub Search - Repository, code, user, Issue, and PR search
    • Academic Search (Google Scholar, arXiv latest papers)
    • Geographic Information Search (Amap API - route planning, geocoding, POI search)
    • Bilibili Video Search
    • Douban Movie/Book/Review Search
    • 12306 Train Information Query
    • WeChat Official Account Article Search
    • Local Semantic Search (RAG - supports PDF, TXT, MD, DOCX)
    • SAI Memos Knowledge Base Search
  • Operation Tools:: safety and interactions
    • Browser Automation (Playwright - web navigation, interaction, content extraction)
    • File System Operations (create, read, write, delete, supports CSV/PDF/JSON)
    • Python Code Execution (IPython backend - state persistence, result capture)
    • Terminal Command Execution (timeout control, output capture)
    • Basic Tool Kit (date/time, UUID, random numbers, and other utilities)

• 🌏 Agent Universe: Provides a pluggable agent architecture supporting multiple agent structures for different tasks. Many more agents are on the way!

• 🧠 Long Horizon Memories: Supports pluggable long-term memory systems for maintaining conversation context across sessions. Sequential memory architecture enables agents to remember and reason over extended interactions with persistent storage.

• 💻 Multi-Backend Services: Offers both Web and CLI backend modes for flexible deployment. One-click setup with zero configuration for quick start, while supporting deep customization for open-source developers.
