Investidor10 MCP Server

Integrations

  • Provides input validation for MCP tools, ensuring data integrity when interacting with the Investidor10 API for stock market data.

Investidor10 - MCP Server

This project is part of the Model Context Protocol (MCP) ecosystem and provides tools to interact with external APIs and manage specific domain models. It is designed to demonstrate how to build an MCP server with external API integration and data validation.

Features

  • get-acoes: Fetch basic stock information.
  • Input validation using Zod.
  • Integration with the Investidor10 API using fetch (infrastructure layer).

Architecture

The project follows a layered architecture inspired by Domain-Driven Design (DDD) patterns:

  • Domain (src/domain): Defines interfaces and types that represent data structures (e.g., Investidor10).
  • Infrastructure (src/infrastructure): Implements external services, such as Investidor10ApiService, responsible for making HTTP calls to the Investidor10 API.
  • Application (src/application): Contains business logic in Investidor10Service, which processes and formats data from the infrastructure.
  • Interface (src/interface): Includes controllers (Investidor10ToolsController) that register tools in the MCP server, define validation schemas, and return results.
  • Entry Point (src/main.ts): Initializes the McpServer, configures the transport (StdioServerTransport), instantiates services and controllers, and starts listening on stdio.

The folder structure is as follows:

src/ ├── domain/ │ └── models/ # Domain interfaces ├── infrastructure/ │ └── services/ # External API implementations (Investidor10) ├── application/ │ └── services/ # Business logic and data formatting ├── interface/ │ └── controllers/ # MCP tool registration and validation └── main.ts # Server entry point build/ # Compiled JavaScript code .vscode/ # Contains the mcp.json file, MCP Server config
