mcp-investidor10
Investidor10 is an MCP server project that integrates with the Investidor10 API to provide stock market data. It is built using Domain-Driven Design principles, focusing on external API integration and input validation.
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.
An integration that enables MCP tools to query stock market data, such as stock prices, and indicators, using the Investidor10 API. |

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 asInvestidor10ApiService
, responsible for making HTTP calls to the Investidor10 API. -
Application (
src/application
): Contains business logic inInvestidor10Service
, 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 theMcpServer
, configures the transport (StdioServerTransport
), instantiates services and controllers, and starts listening on stdio.
The folder structure is as follows:
