## About

Moonbeam Paid Calls exposes five priced tools for agents: on-chain reads on Base (Uniswap V3 pool tokens and fee tier, block hashes), latest prices for BTC, ETH, SOL and some futures symbols, wallet address risk scores, sha256 or keccak256 hashing, and goal-to-steps planning. Answers are checked before the caller is charged.

It runs as a hosted streamable HTTP endpoint. No sign-in or API key is needed. Each tool is a paid call priced in USDC on Base (from 0.0012 to 0.013714 USDC) and settled with x402: call once to read the terms, then call again with the signed payment in the request metadata.

## What it can do

- Read Uniswap V3 pool tokens and fee tier or a block hash on Base
- Get the latest USD price for BTC, ETH, SOL, NQ, ES and YM
- Score the risk of a wallet address on a chosen chain
- Hash text with sha256 or keccak256
- Break a goal into ordered steps
- Pay per call in USDC with x402; failed answers are not charged

## Tools (4)

- `moonbeam_where_listed`: Where an ERC-8004 agent on Base stands on the markets Moonbeam lists agents on: ERC-8004, the MCP Registry and the A2A Registry, each listed, queued, held or not asked. (read-only)
- `data_onchain_query`: Read on-chain facts on Base such as Uniswap V3 pool tokens and fee tier or a block hash; 0.013714… (read-only)
- `market_price`: One market.price answer, bought through Moonbeam and paid with x402 on Base. (read-only)
- `mcp_digest`: Hash of your text with sha256 or keccak256 as hex; 0.0012 USDC. (read-only)

## Example prompts

- "Get the current BTC price from Moonbeam."
- "What risk score does this wallet address have on Base?"
- "Compute the keccak256 hash of this text."
- "Which tokens and fee tier does this Uniswap V3 pool use?"

## Install

### Claude Code

1. Run this in a terminal, in your project folder:

```bash
claude mcp add --transport http moonbeam-paid-calls https://next.moonbeam.network/api/acp/x402/mcp
```

2. Start Claude Code and type `/mcp`. **moonbeam-paid-calls** should show as connected.

Add `--scope user` to make it available in every project, not just this one.

### Claude Desktop

1. Open **Customize → Connectors**, click **+ Add**, then **Add custom connector**.

2. Name it **Moonbeam Paid Calls** and paste this URL:

```url
https://next.moonbeam.network/api/acp/x402/mcp
```

3. Click **Add**. Its tools appear in the chat’s tools menu.

Claude Desktop’s JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.

### claude.ai

1. Open the connector form on claude.ai. This button fills in the name and URL for you:

[Add to claude.ai](<https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=Moonbeam%20Paid%20Calls&connectorUrl=https%3A%2F%2Fnext.moonbeam.network%2Fapi%2Facp%2Fx402%2Fmcp>) (opens connector settings)

2. Check that the URL reads `https://next.moonbeam.network/api/acp/x402/mcp` and click **Add**.

3. Turn it on in a chat from the tools menu.

Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under **Organization settings → Connectors**.

### ChatGPT

1. On chatgpt.com, go to **Plugins**, select **+**, then **Add custom MCP server**.

2. Enter a name for the server.

3. Under **Connection**, paste `https://next.moonbeam.network/api/acp/x402/mcp` as the server URL, then for authentication choose **No authentication**.

4. Check **I understand and want to continue**, then select **Create as a plugin**.

Whether you can add a custom MCP server depends on your ChatGPT plan and your workspace permissions (in Business workspaces, admins and owners can).

### Cursor

[Add to Cursor](<https://cursor.com/install-mcp?name=moonbeam-paid-calls&config=eyJ1cmwiOiJodHRwczovL25leHQubW9vbmJlYW0ubmV0d29yay9hcGkvYWNwL3g0MDIvbWNwIn0%3D>) (opens Cursor)

Or add it by hand to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (this project):

`mcp.json`:

```json
{
  "mcpServers": {
    "moonbeam-paid-calls": {
      "url": "https://next.moonbeam.network/api/acp/x402/mcp"
    }
  }
}
```

### VS Code

[Install in VS Code](<https://vscode.dev/redirect/mcp/install?name=moonbeam-paid-calls&config=%7B%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fnext.moonbeam.network%2Fapi%2Facp%2Fx402%2Fmcp%22%7D>) (opens VS Code)

Or from a terminal:

```bash
code --add-mcp '{"name":"moonbeam-paid-calls","type":"http","url":"https://next.moonbeam.network/api/acp/x402/mcp"}'
```

Or commit it to the repo in `.vscode/mcp.json`:

`.vscode/mcp.json`:

```json
{
  "servers": {
    "moonbeam-paid-calls": {
      "type": "http",
      "url": "https://next.moonbeam.network/api/acp/x402/mcp"
    }
  }
}
```

### Devin Desktop

1. Add it to `~/.config/devin/mcp_config.json` (macOS and Linux) or `%APPDATA%\devin\mcp_config.json` (Windows):

`mcp_config.json`:

```json
{
  "mcpServers": {
    "moonbeam-paid-calls": {
      "serverUrl": "https://next.moonbeam.network/api/acp/x402/mcp"
    }
  }
}
```

2. Refresh the MCP server list in Cascade.

Devin Desktop is the new name for Windsurf. It reads `serverUrl` (or `url`) for remote servers.

### Codex

```bash
codex mcp add moonbeam-paid-calls --url https://next.moonbeam.network/api/acp/x402/mcp
```

Or edit `~/.codex/config.toml` directly:

`config.toml`:

```toml
[mcp_servers.moonbeam-paid-calls]
url = "https://next.moonbeam.network/api/acp/x402/mcp"
```

### Gemini CLI

```bash
gemini mcp add --transport http moonbeam-paid-calls https://next.moonbeam.network/api/acp/x402/mcp
```

This adds it to the current project. Add `-s user` to use it everywhere.

### Any client

Most clients accept this shape. Some name the URL field differently: `serverUrl` in Devin Desktop, `httpUrl` in Gemini CLI’s settings file.

```json
{
  "mcpServers": {
    "moonbeam-paid-calls": {
      "type": "http",
      "url": "https://next.moonbeam.network/api/acp/x402/mcp"
    }
  }
}
```

Zed puts servers under `context_servers` in its settings. Cline needs `"type": "streamableHttp"`, or it assumes SSE.

Client only starts local servers? Bridge it with `npx -y mcp-remote https://next.moonbeam.network/api/acp/x402/mcp`.
