Finance MCP Tools for AI Agents

Your financial advisor agent calculates monthly loan payments and gets a number that's $12 off. For a 30-year mortgage, that error compounds to over $4,300. Financial calculations demand precision — these tools deliver it.

All Finance Tools (15)

Your agent gets access to 15 finance tools via the /mcp/finance/ endpoint. Here's the complete list:

Agent Scenarios

Here's how real agents use these tools:

{ "principal": 300000, "annual_rate": 6.5, "years": 30 }

{ "principal": 10000, "rate": 7, "years": 20 }

{ "rate": 10, "cashflows": [-100000, 30000, 35000, 40000, 45000] }

MCP Setup

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

Claude Desktop / Claude Code

Add this to your MCP config:

{
  "mcpServers": {
    "tinyfn-finance": {
      "url": "https://api.tinyfn.io/mcp/finance/",
      "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/finance/sse
• Headers: X-API-Key: your-api-key

Tip: Use the category-specific endpoint (/mcp/finance/) 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 finance 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.
