CEMIS — MCP server

Read-only MCP server over the data directory of CEMIS: registered Cuban companies, business opportunities derived from Cuba's 2026 economic reforms, and the transformations/reforms themselves.

Listed in the official MCP registry as io.github.francofuji/cemis-directorio.

Connecting

Public server, no authentication (all data is already public on cemis.io):

https://mcp.cemis.io/mcp

Transport: streamable-http. Compatible with any MCP client (Claude Desktop, ChatGPT with custom connectors, etc.) — add it as a remote HTTP server.

Related MCP server: cnes-mcp-test

Tools

Local development

cd mcp_server
python3.11 -m venv venv
./venv/bin/pip install -r requirements.txt
./venv/bin/python -m pytest tests/ -v   # 25 tests, 100% local
MCP_TRANSPORT=stdio ./venv/bin/python server.py

To run in HTTP mode (the same server.py, without forking the code):

MCP_TRANSPORT=streamable-http MCP_PORT=8000 ./venv/bin/python server.py

Docker

docker build -f mcp_server/Dockerfile -t cemis_mcp .
docker run -p 8000:8000 cemis_mcp

Structure

• cemis_core/: matching keywords and shared functions (company↔opportunity↔transformation), with no dependency on the site.

• data.py, oportunidades_data.py, estados_transformaciones.py, empresas_data.json: the same data published at cemis.io.

• mcp_server/: the MCP server itself.

This repo is a subset of the full cemis.io project (which also includes the static site generator) — only what is needed to run the MCP server independently lives here.
