Status Invest - 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.
- get-indicadores: Fetch detailed stock indicator information.
- get-acoes-datas-pagamento: Fetch stock payment dates.
- Input validation using Zod.
- Integration with the Status Invest 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., StatusInvest).

- Infrastructure (src/infrastructure):
Implements external services, such as StatusInvestApiService, responsible for making HTTP calls to the Status Invest API.

- Application (src/application):
Contains business logic in StatusInvestService, which processes and formats data from the infrastructure.

- Interface (src/interface):
Includes controllers (StatusInvestToolsController) 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:
