What It Is

jayzheng.com is Jay Zheng’s personal technical homepage, centered on “building with AI.” It is not a traditional SaaS product website, but a personal site showcasing the author’s current areas of exploration, projects, and reading list. The content shows a focus on MCP servers, agent tooling, semantic code search, scaling laws, in-context learning, and building a Claude Code-like agent from scratch to understand the agentic loop.

Core Capabilities and Notable Projects

The page lists three main projects: VectCode, HAC, and Football Data. VectCode is a semantic code search tool based on vector embeddings, combined with an MCP server. Its tech stack includes Go, ChromaDB, Ollama, and MCP, making it a useful reference for developers interested in local code retrieval and agent tool integration. HAC, short for HTTP Agent Context, is a secure metadata specification for interactions between AI agents and APIs, using an RFC-style spec and JSON Schema. Football Data combines an NFL data pipeline, machine learning predictions, and an LLM panel deliberation system, involving Go, Python, SQLite, scikit-learn, Claude API, and React.

Pricing, Trials, and Integrations

The page does not disclose any commercial pricing, free tier, trial policy, or payment methods, so it should not be treated as a fully productized paid tool. In terms of integrations, keywords such as MCP server, Claude API, Ollama, ChromaDB, and JSON Schema are clearly mentioned, indicating that the author’s projects lean toward AI agent engineering, retrieval augmentation, and tool-protocol integration. However, there is no complete installation documentation, API usage guide, or online demo information.

Strengths, Weaknesses, and Limitations

Its main strength is a highly focused direction, covering cutting-edge engineering topics such as AI agents, MCP, semantic code search, and secure metadata specifications. It also provides GitHub project links, making it suitable for developers who want to inspect the implementations in depth. The limitations are also clear: the page is relatively concise and lacks information on project maturity, performance metrics, deployment methods, privacy policy, service support, and Chinese-language support. For non-technical users, it is not an out-of-the-box tool; for enterprise users, it also lacks production-grade information such as compliance, permissions, and SLA.

Who It’s For and Access from China

This site is better suited to AI engineers, agent-toolchain researchers, and developers looking for references on MCP Server or semantic code search implementations. Access from mainland China is not stated in the content, so its availability is unknown. If the projects depend on external services such as GitHub or Claude API, actual usage may be affected by network conditions and account availability. Alternative references include Cursor, Continue, Aider, Sourcegraph Cody, or self-built semantic code search and agent toolchains based on Ollama and ChromaDB.
