### Initialize MCP Server with Currency Tools (TypeScript)

Source: https://context7.com/wesbos/currency-conversion-mcp/llms.txt

Initializes the MCP server and registers currency conversion tools like convert_currency, get_latest_rates, get_currencies, and get_historical_rates. The fetch handler routes requests to the appropriate transport endpoints (/sse or /mcp).

```typescript
import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import { McpAgent } from "agents/mcp";

export class MyMCP extends McpAgent {
  server = new McpServer({
    name: "Currency Converter",
    version: "1.0.0",
  });

  async init() {
    this.server.tool("convert_currency", convertCurrencySchema, async (input) =>
      convertCurrency(input),
    );

    this.server.tool("get_latest_rates", getLatestRatesSchema, async (input) =>
      getLatestRates(input),
    );

    this.server.tool("get_currencies", getCurrenciesSchema, async (input) =>
      getCurrencies(input),
    );

    this.server.tool("get_historical_rates", getHistoricalRatesSchema, async (input) =>
      getHistoricalRates(input),
    );
  }
}

// Worker fetch handler routes requests to appropriate transport endpoints
export default {
  fetch(request: Request, env: Env, ctx: ExecutionContext) {
    const url = new URL(request.url);

    if (url.pathname === "/sse" || url.pathname === "/sse/message") {
      return MyMCP.serveSSE("/sse").fetch(request, env, ctx);
    }

    if (url.pathname === "/mcp") {
      return MyMCP.serve("/mcp").fetch(request, env, ctx);
    }

    return new Response("Not found", { status: 404 });
  },
};

None

#### Request Body
None (Configuration is done via code)

### Request Example
```typescript
import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import { McpAgent } from "agents/mcp";

export class MyMCP extends McpAgent {
  server = new McpServer({
    name: "Currency Converter",
    version: "1.0.0",
  });

  async init() {
    this.server.tool("convert_currency", convertCurrencySchema, async (input) =>
      convertCurrency(input),

}

// Worker fetch handler routes requests to appropriate transport endpoints
export default {
  fetch(request: Request, env: Env, ctx: ExecutionContext) {
    const url = new URL(request.url);

    if (url.pathname === "/sse" || url.pathname === "/sse/message") {
      return MyMCP.serveSSE("/sse").fetch(request, env, ctx);
    }

    if (url.pathname === "/mcp") {
      return MyMCP.serve("/mcp").fetch(request, env, ctx);
    }

    return new Response("Not found", { status: 404 });
  },
};
```

### Response
#### Success Response (200)
Server initialization is a configuration step and does not directly return a response to an API call in this context. The `init` method configures the server to handle subsequent tool calls.

#### Response Example
N/A

### Convert Currency Tool (TypeScript)

Source: https://context7.com/wesbos/currency-conversion-mcp/llms.txt

Defines the schema for currency conversion and implements the logic to convert an amount from a source currency to a target currency using the Frankfurter API. It handles potential API errors and returns the converted amount.

```typescript
import { z } from "zod";

const convertCurrencySchema = {
  from: z.string().length(3).describe("Source currency code (e.g., USD, EUR)"),
  to: z.string().length(3).describe("Target currency code (e.g., USD, EUR)"),
  amount: z.number().positive().describe("Amount to convert"),
};

type ConvertCurrencyInput = {
  from: string;
  to: string;
  amount: number;
};

async function convertCurrency(input: ConvertCurrencyInput): Promise<ToolResponse> {
  const { from, to, amount } = input;

  try {
    const url = `https://api.frankfurter.dev/v1/latest?base=${from.toUpperCase()}&symbols=${to.toUpperCase()}`;
    const response = await fetch(url);

    if (!response.ok) {
      return {
        content: [{
          type: "text",
          text: `Error: Unable to fetch exchange rate. Status: ${response.status}`,
        }],
      };
    }

    const data = await response.json();
    const rate = data.rates[to.toUpperCase()];
    const convertedAmount = Math.round(amount * rate * 100) / 100;

    const result = {
      ...data,
      conversion: {
        from: from.toUpperCase(),
        to: to.toUpperCase(),
        amount: amount,
        result: convertedAmount,
        rate: rate,
      },
    };

    return {
      content: [{
        type: "text",
        text: JSON.stringify(result),
      }],
    };
  } catch (error) {
    return {
      content: [{
        type: "text",
        text: `Error: Failed to convert currency - ${error instanceof Error ? error.message : "Unknown error"}`,
      }],
    };
  }
}

// Example usage: Convert 100 USD to EUR
const result = await convertCurrency({ from: "USD", to: "EUR", amount: 100 });
// Returns: {"base":"USD","date":"2024-01-15","rates":{"EUR":0.92},"conversion":{"from":"USD","to":"EUR","amount":100,"result":92.00,"rate":0.92}}
