MCP Server for Comexstat API

This project implements an MCP (Model Context Protocol) server for the Comexstat API, allowing AI models like Claude to interact directly with Brazil's foreign trade data.

Overview

The MCP Comexstat server provides tools to query Brazilian export and import statistics, including:

• General export and import data

• Data by municipalities

• Historical data (1989-1996)

• Auxiliary tables with codes and descriptions

Related MCP server: br-eli-mcp

Features

• Implemented using @modelcontextprotocol/sdk

• Typing with TypeScript

• Data validation with Zod

• Support for communication via stdin/stdout (MCP standard)

• Robust API error handling and responses

• getAvailableFilters() - Lists available filters

• getFilterValues(filter, language?) - Gets values for a specific filter

• getAvailableFields() - Lists the fields available for detailing

• getAvailableMetrics() - Lists available metrics

• queryData(options) - Performs detailed queries with the following parameters:

  • flow : "export" | "import"

  • period : { from: "YYYY-MM", to: "YYYY-MM" }

  • monthDetail : boolean

  • filters : Array of filters (optional)

  • details : Array of fields for detailing

  • metrics : Array of metrics

  • language : string (optional, default: "pt")

Usage Example

// Consultar exportações para os EUA em 2023
const result = await queryData({
  flow: "export",
  period: { from: "2023-01", to: "2023-12" },
  monthDetail: false,
  filters: [{ filter: "country", values: [105] }],
  details: ["country", "month"],
  metrics: ["metricFOB", "metricKG"],
});

Integration with Claude

To use the MCP server with Claude Desktop:

1. Add the configuration to the claude_desktop_config.json file:

   {
     "mcpServers": {
       "comexstat": {
         "command": "node",
         "args": ["/caminho/completo/para/mcp-comexstat-easy/dist/index.js"]
       }
     }
   }

2. On Claude Desktop, use the command:

   /mcp comexstat
