Latest News
AgentIndex CLI section added to the Awesome Cursor Rules & MCP Servers repository, documenting npx search, tool and category commands.
Companion repository added CC0 licensing and contributing guidelines.
@agentindex-app/cli version 0.1.0 was published to npm, providing terminal search of the AgentIndex directory.
AgentIndex profile activity recorded creation of the awesome-agents repository and current maintenance activity by xiaozhenyangCode.
Products & Services
Searchable directory of open-source AI agents, MCP servers, frameworks and developer tools. It provides categories, rankings, GitHub-derived stars/license/update metadata, AI-assisted summaries, features, use cases, install commands, comparisons and alternatives.
Public npm CLI (version 0.1.0, published a day before the 2026-10-22 research date) for searching AgentIndex from a terminal without an API key. Supports find, tool and category commands, category filtering, result limits, JSON output and a configurable API base.
Remote MCP endpoint at https://agentindex.app/api/mcp/ that exposes search_tools, get_tool_detail, list_categories, get_trending and submit_tool for MCP clients and AI agents.
CC0-licensed GitHub collection of best practices, .cursorrules files and MCP servers for Cursor, Windsurf and VSCode, linking users to AgentIndex for the searchable collection.
Market Position
AgentIndex positions itself as an independent, curated directory spanning AI agents, MCP servers and broader developer tooling, rather than only an MCP marketplace. Its differentiation is the combination of GitHub-derived maintenance metadata, AI-assisted project summaries, comparisons, install commands, a terminal CLI and a remote MCP interface. Comparable discovery products include Glama’s open-source MCP-server directory and Smithery’s MCP-server catalog; AgentIndex’s stated scope is broader and includes frameworks, RAG, workflow automation, browser automation and coding tools.
Leadership
Founders
oneday (GitHub: xiaozhenyangCode)
An independent developer who describes himself on GitHub as a mobile-focused engineer (Chinese: “一名深耕于移动端的工程”) and as a 10-year iOS developer on AgentIndex. His public GitHub work includes Objective-C/Swift projects such as -GCD-, runtime, RxSwift, XZYRefreshExample and UtilityClass.
Executive Team
oneday (xiaozhenyangCode)
Independent developer / creator
Mobile-focused engineer and 10-year iOS developer; maintains AgentIndex.app and the associated open-source/tool-directory projects.
Founding Story
Public materials identify AgentIndex as an independent-developer project rather than a formally described company. The apparent motivation was to make the creator’s collection of Cursor rules, MCP servers and AI developer tools easier to search and use: the companion repository describes the collection as a way to supercharge Cursor, Windsurf and VSCode, while AgentIndex describes its goal as helping developers find and compare the right tool faster.
