# Cloudflare Agents

Use [`McpClient.wrap`](/sdk/typescript/client/McpClient.wrap) and [`Mppx.create`](/sdk/typescript/client/Mppx.create) to let a [Cloudflare Agent](https://developers.cloudflare.com/agents/) pay for MCP tools and HTTP requests through MPP. Free calls pass through untouched; when a paid tool or a 402-protected request returns an MPP Challenge, the wrapped client creates a Credential, retries the call, and returns the result.

```bash [terminal]
$ pnpm add agents mppx viem
```

```ts [payments.ts]
import { privateKeyToAccount } from 'viem/accounts'

export const account = privateKeyToAccount(process.env.PRIVATE_KEY as `0x${string}`)
```

:::info
The example uses an environment private key for brevity. For production agents, manage spend with scoped access keys instead of giving the runtime a private key. See [Managing agent spend](/guides/managing-agent-spend).
:::

## Pay for MCP tools

Add the MCP server, then wrap the client stored on the Cloudflare MCP connection. Calls through the wrapped client are payment-aware.

```ts [agent.ts]
import { Agent } from 'agents'
import { tempo } from 'mppx/client'
import { McpClient } from 'mppx/mcp/client'
import { account } from './payments'

what is this local import? can we just inline this?

it makes a little more sense in the rendered guide - but the "account" is created once on line 17 and then used on line 38 and 62 - so would have to inline in two places wdyt.

lmk what you think this is the only comment i didnt address


export class MyAgent extends Agent {
async onStart() {
const { id } = await this.addMcpServer('premium-search', '<mcp-url>')
const client = McpClient.wrap(this.mcp.mcpConnections[id].client, {
methods: [tempo({ account })],
})

const result = await client.callTool({
name: 'premium_search',
arguments: { query: 'tempo' },
})

console.log(result)
}
}
```

`McpClient.wrap` keeps the Cloudflare MCP connection shape intact. The agent can keep using the same client APIs.

## Pay for HTTP requests

Call `Mppx.create` before the agent makes HTTP requests. It installs the payment-aware fetch, so later `fetch` calls in the same runtime can handle free responses, paid MPP responses, and [x402 payment challenges](/guides/use-mpp-with-x402).

```ts [agent.ts]
import { Mppx, tempo } from 'mppx/client'
import { account } from './payments'

Mppx.create({
methods: [tempo({ account })],
})

export async function paidPing() {
const response = await fetch('https://mpp.dev/api/ping/paid')
return response.json()
}
```

## Manage agent spend

The examples above use a standard viem account. For long-running apps or agents, use scoped access keys when the runtime should pay in the background with spending limits, call scopes, recipient restrictions, and independent revocation.
Comment thread
parvahuja marked this conversation as resolved.

Create the access key first, then pass the Tempo account into the same setup.

```ts [agent.ts]
const method = tempo({
account: provider.getAccount(),
...provider.getMppxParameters({ accessKey }),
})

// Use the method for paid MCP tool calls.
McpClient.wrap(this.mcp.mcpConnections[id].client, {
methods: [method],
})

// Use the same method for payment-aware fetch calls.
Mppx.create({
methods: [method],
})
```

See [Managing agent spend](/guides/managing-agent-spend) for limits, scopes, recipients, and revocation.

# Official MCP SDK

Use [`Mppx.create`](/sdk/typescript/client/Mppx.create) to let the [official TypeScript MCP SDK](https://github.com/modelcontextprotocol/typescript-sdk) pay for MCP tools and HTTP requests through MPP. Free calls pass through untouched; when a paid tool or a 402-protected request returns an MPP Challenge, the payment-aware fetch wrapper creates a Credential, retries the call, and returns the result.

```bash [terminal]
$ pnpm add mppx viem @modelcontextprotocol/sdk
```

```ts [payments.ts]
import { Mppx, tempo } from 'mppx/client'
import { privateKeyToAccount } from 'viem/accounts'

const account = privateKeyToAccount(process.env.PRIVATE_KEY as `0x${string}`)

Mppx.create({
methods: [tempo({ account })],
})
```

## Pay for MCP tools

Create the MCP client after `Mppx.create`. The Streamable HTTP transport uses the payment-aware fetch for both free and paid tool calls.

```ts [client.ts]
import { Client } from '@modelcontextprotocol/sdk/client/index.js'
import { StreamableHTTPClientTransport } from '@modelcontextprotocol/sdk/client/streamableHttp.js'
import './payments'

const client = new Client({
name: 'mpp-app',
version: '1.0.0',
})

await client.connect(new StreamableHTTPClientTransport(new URL('<mcp-url>')))

const result = await client.callTool({
name: 'premium_search',
arguments: { query: 'tempo' },
})

console.log(result)
```

## Pay for HTTP requests

Call `Mppx.create` before making HTTP requests. It installs the payment-aware fetch, so later `fetch` calls in the same runtime can handle free responses, paid MPP responses, and [x402 payment challenges](/guides/use-mpp-with-x402).

```ts [client.ts]
import './payments'

export async function paidPing() {
const response = await fetch('https://mpp.dev/api/ping/paid')
return response.json()
}
```

# Vercel AI SDK

Use [`Mppx.create`](/sdk/typescript/client/Mppx.create) to let a [Vercel AI SDK agent](https://ai-sdk.dev/docs/agents/overview) pay for MCP tools and HTTP requests through MPP. Free calls pass through untouched; when a paid tool or a 402-protected request returns an MPP Challenge, the wrapped client creates a Credential, retries the call, and returns the result.

```bash [terminal]
$ pnpm add mppx viem ai @ai-sdk/mcp zod
```

```ts [payments.ts]
import { Mppx, tempo } from 'mppx/client'
import { privateKeyToAccount } from 'viem/accounts'

const account = privateKeyToAccount(process.env.PRIVATE_KEY as `0x${string}`)

Mppx.create({
methods: [tempo({ account })],
})
```

## Pay for MCP tools

Create the MCP client after `Mppx.create`. The AI SDK MCP transport uses the payment-aware fetch for both free and paid tool calls.

```ts [agent.ts]
import { createMCPClient } from '@ai-sdk/mcp'
import { generateText } from 'ai'
import { yourProvider } from 'your-custom-provider'

const mcp = await createMCPClient({
transport: {
type: 'http',
url: '<mcp-url>',
},
})

const { toolResults } = await generateText({
model: yourProvider('your-model-id'),
prompt: 'Call the MCP tool.',
tools: await mcp.tools(),
toolChoice: 'required',
})

console.log(toolResults)
await mcp.close()
```

## Pay for HTTP requests

Define a normal AI SDK tool and call `fetch` inside `execute`. Because `Mppx.create` ran first, the HTTP request is payment-aware.

```ts [agent.ts]
import { generateText, tool } from 'ai'
import { yourProvider } from 'your-custom-provider'
import { z } from 'zod'

const { toolResults } = await generateText({
model: yourProvider('your-model-id'),
prompt: 'Call paidPing.',
tools: {
paidPing: tool({
description: 'Call a paid MPP HTTP endpoint.',
inputSchema: z.object({}),
execute: async () => {
const response = await fetch('https://mpp.dev/api/ping/paid')
return response.json()
},
}),
},
toolChoice: { type: 'tool', toolName: 'paidPing' },
})

console.log(toolResults)
```

The `tempo({ account })` helper used above supports Tempo [charge](/payment-methods/tempo/charge) and [session](/payment-methods/tempo/session) challenges.
