ABOUT THE PROJECT

Small developer tools, maintained in public.

Guagua Tools is an independent project maintained by Alvin Li under the GitHub account dmf6009. The site grew from a recurring problem: MCP configuration and protocol errors often require a small, inspectable check, while the available answer is either a long specification or a black-box service.

The project is not affiliated with Google, Anthropic, Microsoft, OpenAI, the Model Context Protocol project, or any protocol maintainer. Product names identify compatible formats; they do not imply endorsement.

What is original here

The browser tools, validation rules, conversion behavior, examples, field notes, and downloadable agent packages are maintained in the project's public repositories. The site does not scrape tool directories, republish vendor documentation, or generate pages from search keywords. Examples use fictional hosts and placeholder credentials so they can be inspected safely.

How examples are checked

Configuration examples are compared against the parser and serializer implemented by the corresponding tool. Validation notes identify whether a claim comes from a schema rule, a protocol requirement, or a project-specific warning. A passing browser check is not presented as certification: deployment settings, authorization servers, proxies, and package releases still need independent verification.

The full process is documented in the testing and editorial methodology, including update dates, redaction rules, limitations, and correction handling.

Advertising and independence

The site uses Google AdSense code to support hosting and maintenance. Advertising does not determine which tools are listed, what a validator reports, or how a product is described. There are currently no paid rankings, sponsored reviews, affiliate comparisons, or payment-based inclusions.

Corrections and contact

Source code and change history are available in the Guagua Tools repository. If a rule is inaccurate, an example is outdated, or a download behaves differently from its page, use the contact page or open a GitHub issue. Corrections affecting safety or interoperability are prioritized.
