## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## Crypto & DeFi MCP

Crypto & DeFi MCP is a NexGenData tool on Apify that returns DeFi TVL, stablecoin supply, funding rates and prediction-market data as agent tools from public crypto and DeFi data sources.

A Model Context Protocol server that gives AI agents on-chain and crypto-market data — TVL, stablecoins, funding, prediction markets — as callable tools. For crypto and DeFi agent builders.

### 📊 Sample Output

This actor runs as a standby MCP server: it starts, answers tool calls at its `/mcp` endpoint and writes no dataset rows, so there is no row table to show. See the tool list and the sample inputs below.

### 💰 Pricing

**Called-actor charges:** each tool call runs one of our NexGenData data actors on your Apify account, and that actor's own per-result price is charged on top of this server's per-call fee.

| Event | Price (USD) | When it is charged |
|---|---|---|
| Actor Start (`apify-actor-start`) | $0.0005 | Charged when the Actor starts running. Number of events charged depends on Actor memory (one event per GB, minimum one event). |
| Data tool call (`tool-call`) | $0.1 | Charged per tool invocation across the bundle. |
| Bulk results (`bulk-results`) | $0.05 | Charged when a tool returns more than 10 records. |

Pay-per-event: you pay only for what the run delivers. A run that delivers nothing bills no result events (only the actor-start event, when the actor defines one). Example: a run that delivers 100 results costs 100 × $0.1 = $10.00 plus the start fee.

# Actor output Schema

## `mcpEndpoint` (type: `string`):

Connect any MCP client (Claude, Cursor, n8n, the OpenAI Agents SDK) to this server's tools. Stable Standby URL: https://nexgendata--crypto-defi-mcp.apify.actor/mcp — send your Apify API token as an `Authorization: Bearer` header. For a single run started from the Console or API, the endpoint is this run's container URL + /mcp. Each tool call is billed per the Actor's live pay-per-event price.

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {};

// Run the Actor and wait for it to finish
const run = await client.actor("nexgendata/crypto-defi-mcp").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

run_input = {}

# Run the Actor and wait for it to finish
run = client.actor("nexgendata/crypto-defi-mcp").call(run_input=run_input)

## CLI example

```bash
echo '{}' |
apify call nexgendata/crypto-defi-mcp --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,nexgendata/crypto-defi-mcp"
        }
    }
}
```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
