Usage

As MCP Server

Add to your MCP settings (e.g., Claude Desktop):

{
  "mcpServers": {
    "openai": {
      "command": "node",
      "args": ["/path/to/robinsonai-mcp-servers/packages/openai-mcp/dist/index.js"],
      "env": {
        "OPENAI_API_KEY": "your-api-key",
        "OPENAI_DAILY_BUDGET": "10.00",
        "OPENAI_MONTHLY_BUDGET": "200.00"
      }
    }
  }
}

Example: Chat with Cost Estimation

// 1. Estimate cost first
const estimate = await openai_estimate_cost({
  operation: "chat",
  model: "gpt-4",
  input_text: "Your long prompt here...",
  max_tokens: 1000
});

// Response:
{
  "estimated_cost_usd": 0.045,
  "breakdown": {
    "input_tokens": 150,
    "output_tokens": 1000,
    "input_cost": 0.0045,
    "output_cost": 0.06
  },
  "budget_check": {
    "daily_spent": 2.50,
    "daily_remaining": 7.50,
    "requires_approval": false,
    "requires_double_approval": false
  }
}

// 2. If approved, make the call
const response = await openai_chat_completion({
  model: "gpt-4",
  messages: [{ role: "user", content: "Your prompt" }]
});

Example: RAG with Vector Stores + Crawl4AI

// 1. Crawl documentation with Crawl4AI
const docs = await crawl4ai.crawl([
  "https://cortiware.com/docs/hvac",
  "https://cortiware.com/docs/scheduling"
]);

// 2. Create vector store
const vectorStore = await openai_create_vector_store({
  name: "Cortiware HVAC Docs"
});

// 3. Upload crawled content
for (const doc of docs) {
  const file = await openai_upload_file({
    file_path: doc.path,
    purpose: "assistants"
  });
  
  await openai_create_vector_store_file({
    vector_store_id: vectorStore.id,
    file_id: file.id
  });
}

// 4. Create assistant with vector store
const assistant = await openai_create_assistant({
  name: "Cortiware HVAC Expert",
  model: "gpt-4-turbo",
  tools: [{ type: "file_search" }],
  tool_resources: {
    file_search: {
      vector_store_ids: [vectorStore.id]
    }
  }
});

// 5. Ask questions - assistant auto-searches docs!
const thread = await openai_create_thread();
await openai_create_message({
  thread_id: thread.id,
  content: "How do I schedule preventive maintenance?"
});

const run = await openai_create_run({
  thread_id: thread.id,
  assistant_id: assistant.id
});

// Assistant automatically searches vector store and responds with citations!
