Health Calculation MCP Tools for AI Agents

Your fitness agent calculates BMI as weight divided by height. But is height in meters or centimeters? And is weight in kg or lbs? Formula confusion and unit mix-ups make health calculations unreliable from LLMs. These tools use the correct formulas with proper unit handling.

All Health Tools (9)

Your agent gets access to 9 health tools via the /mcp/health/ endpoint. Here's the complete list:

Agent Scenarios

Here's how real agents use these tools:

{ "weight_kg": 75, "height_cm": 180 }

{ "weight_kg": 75, "height_cm": 180, "age": 30, "gender": "male" }

{ "height_cm": 175, "gender": "female" }

MCP Setup

Add health tools to your agent in under 2 minutes. Choose your client:

Claude Desktop / Claude Code

Add this to your MCP config:

{
  "mcpServers": {
    "tinyfn-health": {
      "url": "https://api.tinyfn.io/mcp/health/",
      "headers": {
        "X-API-Key": "your-api-key"
      }
    }
  }
}

Cursor

Go to Settings > MCP and add a new server:

• Type: SSE
• URL: https://api.tinyfn.io/mcp/health/sse
• Headers: X-API-Key: your-api-key

Tip: Use the category-specific endpoint (/mcp/health/) for the best experience. The all-in-one endpoint (/mcp/all/) works too but has 500+ tools which some clients handle less efficiently.

When to Use These Tools

Use health MCP tools when your agent needs to:

• Guarantee correctness — when wrong answers have real consequences
• Process user data — when you're operating on actual user input, not hypothetical examples
• Maintain consistency — when the same input must always produce the same output

You don't need these tools for casual conversation or rough estimates. Use them when precision matters.
