Equity Metrics Retrieval Node
This is a TypeScript-based Message Context Protocol (MCP) server engineered to fetch granular stock market metrics. It leverages the robustness of the Alpha Vantage API to deliver up-to-the-minute quotations and comprehensive corporate fiscal documentation.
Essential Setup References
- .clinerules for server boilerplate information.
- API Credential Portal to secure your access token.
md 1.Plan mode
I require the construction of an MCP server utilizing the AlphaVantage REST service for financial data acquisition. The required functionalities include:
- Delivery of a consolidated U.S. market briefing.
- Extraction of detailed financial statements for specified entities.
- Real-time quoting for individual stock tickers.
- Inclusion of any supplementary, contextually relevant analytical tools.
- API Key Injection Point:
- please test all the tools to confirm their functionality
Operational Capabilities

Configuration and Deployment
Dependency Installation
Execute the following in your terminal: bash npm install
Compilation Process
To build the production artifacts: bash npm run build
Iterative Development Mode
Use this command for auto-reloading on file changes: bash npm run watch
Integration Procedure
To enable this server within the Claude Desktop environment, modify the configuration file as follows:
MacOS Location
Configuration file path: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows Location
Configuration file path: %APPDATA%/Claude/claude_desktop_config.json
Example Configuration Snippet:
{ "mcpServers": { "financial-data-retriever-service": { "command": "/path/to/financial-data-retriever-service/build/index.js" } } }
Troubleshooting
Debugging inter-process communication via STDIN/STDOUT can be complex. We strongly advise utilizing the dedicated MCP Inspector utility:
bash npm run inspector
This command initiates the Inspector, furnishing a reachable URL for advanced browser-based inspection tools.
Underlying Technology Stack
- Programming Language: TypeScript
- Runtime Environment: Node.js
- Data Source: Alpha Vantage API
- Framework: MCP SDK (@modelcontextprotocol/sdk)
Critical Considerations
- Authentication requires a valid, active API authorization key from Alpha Vantage.
- All data payloads returned by the service will adhere strictly to the JSON serialization standard.
- Users must remain cognizant of the rate limiting policies enforced by the external API provider.

WIKIPEDIA: XMLHttpRequest (XHR) is an API in the form of a JavaScript object whose methods transmit HTTP requests from a web browser to a web server. The methods allow a browser-based application to send requests to the server after page loading is complete, and receive information back. XMLHttpRequest is a component of Ajax programming. Prior to Ajax, hyperlinks and form submissions were the primary mechanisms for interacting with the server, often replacing the current page with another one.
== History == The concept behind XMLHttpRequest was conceived in 2000 by the developers of Microsoft Outlook. The concept was then implemented within the Internet Explorer 5 browser (1999). However, the original syntax did not use the XMLHttpRequest identifier. Instead, the developers used the identifiers ActiveXObject("Msxml2.XMLHTTP") and ActiveXObject("Microsoft.XMLHTTP"). As of Internet Explorer 7 (2006), all browsers support the XMLHttpRequest identifier. The XMLHttpRequest identifier is now the de facto standard in all the major browsers, including Mozilla's Gecko layout engine (2002), Safari 1.2 (2004) and Opera 8.0 (2005).
=== Standards === The World Wide Web Consortium (W3C) published a Working Draft specification for the XMLHttpRequest object on April 5, 2006. On February 25, 2008, the W3C published the Working Draft Level 2 specification. Level 2 added methods to monitor event progress, allow cross-site requests, and handle byte streams. At the end of 2011, the Level 2 specification was absorbed into the original specification. At the end of 2012, the WHATWG took over development and maintains a living document using Web IDL.
== Usage == Generally, sending a request with XMLHttpRequest has several programming steps.
Create an XMLHttpRequest object by calling a constructor: Call the "open" method to specify the request type, identify the relevant resource, and select synchronous or asynchronous operation: For an asynchronous request, set a listener that will be notified when the request's state changes: Initiate the request by calling the "send" method: Respond to state changes in the event listener. If the server sends response data, by default it is captured in the "responseText" property. When the object stops processing the response, it changes to state 4, the "done" state. Aside from these general steps, XMLHttpRequest has many options to control how the request is sent and how the response is processed. Custom header fields can be added to the request to indicate how the server should fulfill it, and data can be uploaded to the server by providing it in the "send" call. The response can be parsed from the JSON format into a readily usable JavaScript object, or processed gradually as it arrives rather than waiting for the entire text. The request can be aborted prematurely or set to fail if not completed in a specified amount of time.
