🧠 MCP - Model Context Protocol

Projeto completo para uma aplicação conversacional com:

  • ✅ FastAPI + JWT
  • ✅ LLM local via Ollama (ex: Mistral)
  • ✅ Contexto com memĂłria vetorial (ChromaDB)
  • ✅ Suporte a mĂșltiplos usuĂĄrios e sessĂ”es
  • ✅ Resumo automĂĄtico de histĂłrico longo
  • ✅ Sistema de plugins para executar açÔes reais

🚀 Como rodar

1. Clone o projeto e crie o ambiente

git clone <repo>
cd mcp
python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

2. Configure o .env

MODEL_NAME=mistral
VECTOR_DB_PATH=./chroma
DB_PATH=./mcp.db
CONTEXT_LIMIT=5
SUMMARY_TRIGGER=20

3. Inicie o Ollama

4. Suba o servidor

chmod +x start.sh
./start.sh

  "prompt": "plugin: {\"name\": \"list_files\", \"args\": {\"path\": \"/etc\"}}"
}
