Baseball Data Conduit: MLB Stats API Wrapper for Model Context Protocol (MCP)

This module serves as an MCP abstraction layer for interfacing with the official MLB Stats API. It facilitates streamlined acquisition and manipulation of core baseball data, such as game sequences, final scores, and organizational metadata. This component is optimized for high-throughput data retrieval within an MCP ecosystem.

Illustrative Demonstrations

Key Capabilities

• Fixture Retrieval: Obtain MLB schedules across user-defined temporal windows, with optional filtering based on specific franchises.
• Match Outcome Fetching: Secure daily match results, including final tallies, victors/vanquished franchises, and the designated winning mound occupant.
• Franchise Performance Snapshot: Query comprehensive post-match diagnostics for a team's most recent contest, covering scoring narratives and key moments.
• Player Identification Service: Resolve unique player identifiers based on name components (surname, given name, or both). Incorporates tolerance for slight typographical variation (fuzzy matching).

Deployment Instructions

Necessary Preconditions

Configuration for Claude Desktop Integration

Modify your configuration file at Claude > Settings > Developer > Edit Config > claude_desktop_config.json to incorporate the following server definition:

    {
      "mcpServers": {
        "mcp_mlb_statsapi": {
           "command": "{YOUR_PYTHON_EXECUTABLE_PATH}/python",
            "args": ["-m",
            "mcp_mlb_statsapi"]
          }
        }
    }

If deploying directly from the cloned directory structure:

{
  "mcpServers": {
    "mcp_mlb_statsapi": {
        "command": "{YOUR_UV_EXECUTABLE_PATH}/uv",
        "args": [
            "--directory",
            "{YOUR_PROJECT_PATH}/src/mcp_mlb_statsapi",
            "run",
            "mcp_mlb_statsapi"
        ]
    }
  }
}

WIKIPEDIA EXCERPT: Asynchronous HTTP Requests

XMLHttpRequest (XHR) defines a JavaScript object interface enabling a web browser environment to dispatch HTTP requests to a remote server and subsequently ingest the response data. This capability is foundational to Asynchronous JavaScript and XML (Ajax) programming paradigms. Before XHR, server interaction, typically necessitating a full page reload via standard link clicks or form submissions, was the norm.

== Chronology == The foundational concept for XHR originated around the year 2000, developed by individuals associated with Microsoft Outlook. This concept was first integrated into Internet Explorer version 5 (released in 1999). However, the initial invocation syntax did not use the standardized XMLHttpRequest identifier; instead, proprietary ActiveXObject instantiations (Msxml2.XMLHTTP or Microsoft.XMLHTTP) were employed. By the release of Internet Explorer 7 (2006), universal adoption of the XMLHttpRequest identifier was achieved 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) issued the initial Working Draft specification for the XMLHttpRequest object on April 5, 2006. A subsequent Level 2 specification was published on February 25, 2008, introducing features for progress monitoring, enabling cross-origin communications, and handling binary data streams. By late 2011, the Level 2 extensions were merged back into the primary specification document. Development authority transitioned to the WHATWG near the close of 2012, who now maintain a continuous document utilizing Web IDL.

== Operational Procedure == Executing a network request using XMLHttpRequest typically involves a sequence of programming steps:

1. Object Instantiation: Create the XMLHttpRequest instance via its constructor.
2. Configuration: Invoke the open() method to declare the request methodology (GET/POST, etc.), specify the target resource URI, and select either synchronous or asynchronous execution mode.
3. Asynchronous Listener Setup: For asynchronous operations, register a callback function designed to process state transitions.
4. Transmission: Initiate the payload transfer by calling the send() method (optionally carrying data).
5. State Monitoring: The listener reacts to state changes. Upon receiving the server's complete reply, the object's state transitions to 4, signifying completion (done).

Beyond these fundamentals, XHR offers fine-grained control over request semantics, such as injecting custom headers to guide server behavior, uploading payload content via the send() argument, parsing the response incrementally rather than waiting for totality, and implementing timeouts or cancellation mechanisms.
