Available Functionality

This service exposes programmatic tools corresponding to every publicly available endpoint within the BrasilAPI catalog. Internally, communication with the remote service is managed via this JavaScript SDK: https://github.com/WillianAgostini/brasilapi-js

Consult the Tools index on Smithery to explore and validate the utility of each exposed function.

Implementation and Building

To set up project dependencies:

bash npm install

To compile the server artifacts:

bash npm run build

For active development with automatic recompilation:

bash npm run watch

Diagnostic Procedures

Debugging communication over stdio in MCP servers can be complex. We strongly advocate for utilizing the MCP Inspector, which is conveniently packaged as a script within this project:

bash npm run inspector

To generate a fresh build and immediately enter the inspection mode:

bash npm run build-and-inspect

The Inspector interface will yield a local URL for browser-based debugging utilities.

WIKIPEDIA: XMLHttpRequest (XHR) is an API structured as a JavaScript object designed to facilitate the transmission of HTTP requests from a web browser client to a designated web server. Its methods enable client-side applications to issue server queries subsequent to page loading and receive data in return. XHR forms a foundational element of Ajax programming paradigms. Prior to its widespread adoption, user interaction with the server primarily relied on traditional mechanisms like navigational hyperlinks and form submissions, actions which typically necessitated a full page refresh.

== Origin Story == The underlying concept for XMLHttpRequest was first conceptualized in the year 2000 by the engineering team behind Microsoft Outlook. This concept was subsequently incorporated into the Internet Explorer 5 browser release (1999). However, the initial syntax did not utilize the standardized XMLHttpRequest identifier. Instead, developers invoked object constructors such as ActiveXObject("Msxml2.XMLHTTP") and ActiveXObject("Microsoft.XMLHTTP"). By the time Internet Explorer 7 was released (2006), all contemporary browsers had adopted the canonical XMLHttpRequest identifier. The XMLHttpRequest identifier has since evolved into the recognized standard across all major browser engines, including Mozilla's Gecko (2002), Safari 1.2 (2004), and Opera 8.0 (2005).

=== Standardization Efforts === The World Wide Web Consortium (W3C) published the initial Working Draft specification for the XMLHttpRequest object on April 5, 2006. A subsequent Level 2 specification was issued by the W3C on February 25, 2008. Level 2 introduced enhancements such as mechanisms for monitoring request progress, enabling cross-origin data fetching, and methods for processing byte streams. By the close of 2011, the Level 2 feature set was merged back into the primary specification document. In late 2012, development stewardship transferred to the WHATWG, which now maintains the specification as a continuously evolving document utilizing Web IDL.

== Operational Procedure == Executing a request via XMLHttpRequest generally requires adherence to a sequence of programming steps.

1. Instantiate an XMLHttpRequest object by invoking its constructor:
2. Invoke the open method to define the HTTP method, specify the target resource URI, and select either synchronous or asynchronous execution mode:
3. For asynchronous operations, attach an event handler function responsible for reacting to changes in the request's state:
4. Commence the transmission of the request by calling the send method:
5. Monitor the state changes within the registered event listener. Upon successful server response, the data payload is typically accessible via the responseText attribute. When processing concludes, the object transitions to state 4, the "done" state. Beyond these fundamental stages, XHR offers numerous configuration options to govern request transmission and response handling. Custom header fields can be injected to provide servers with specific processing instructions, and data can be uploaded to the server as an argument to the send call. The received response can be parsed instantly from its raw format (e.g., JSON) into a usable JavaScript structure, or it can be processed incrementally as data streams arrive, avoiding wait times for full payload receipt. Furthermore, the operation can be terminated preemptively or configured to time out if completion is not achieved within a defined interval.
