# MCP Registry Scraper (`thearchitect0x/mcp-registry-scraper`) Actor

Metadata only: no MCP server is ever contacted. Every server in the official MCP registry and Smithery as normalized, deduplicated records with hosting concentration, provenance flags and an integrity score.

## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.
Actors are written with capital "A".

## 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.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## MCP Registry Scraper

> **Metadata only. No MCP server is ever contacted.**
> This actor reads two public registry APIs, `registry.modelcontextprotocol.io` and
> `registry.smithery.ai`. It never connects to, probes or sends a request to any MCP server
> listed in them.

Enumerates every server in the **official Model Context Protocol registry** (101,000+
entries) and **Smithery** (14,000+), and returns clean, deduplicated records.

### What you get per record

- `name`, `title`, `publisher`, `description`, `version`
- `isLatest` — the official registry keeps every historical version; 69% of entries are
  superseded. Turn on *Latest versions only* to collapse 101k → ~31k real servers.
- `remoteHost` + `hostSharedWith` — how many other "servers" point at the same hostname.
  Some hosts front 2,000+ entries. Useful for spotting aggregators and bulk registration.
- `hasRepository` — 15% of entries have no source repo at all.
- `flags` — `injection-shaped-text`, `invisible-chars`, `shared-host-50plus`
- Smithery adds `useCount`, `verified`, `isDeployed`

### Why

Every "how many MCP servers exist" number in circulation counts versions as servers.
This actor gives you the real population, deduplicated, with the concentration and
provenance signals nobody else exposes.

### Typical uses

- Ecosystem research and market sizing
- Tool discovery with a spam / aggregator filter
- Security review: which listed servers are auditable (have a repo), which share hosts
- Tracking growth: run weekly, diff the datasets

### Pricing

Pay per result. A full official-registry run at *Latest only* is ~31,000 results.
Test with `maxItems: 500` first.

### Limits

Published metadata is not observed behaviour — a declared HTTPS endpoint is not proof
the server is up. Glama is not included (requires an API key under a licence with
attribution terms).

# Actor input Schema

## `registries` (type: `array`):

Which registries to enumerate.

## `latestOnly` (type: `boolean`):

Drop superseded versions. The official registry keeps every historical version; with this on, 101k entries collapse to ~31k distinct servers.

## `maxItems` (type: `integer`):

Stop after this many records (0 = all). Useful for a cheap test run.

## `computeHostConcentration` (type: `boolean`):

Adds hostSharedWith: how many other servers point at the same hostname. Requires a full run.

## Actor input object example

```json
{
  "registries": [
    "official"
  ],
  "latestOnly": true,
  "maxItems": 500,
  "computeHostConcentration": true
}
```

# Actor output Schema

## `servers` (type: `string`):

One record per registry entry: name, publisher, version, isLatest, status, remoteHost, hostSharedWith, hasRepository, repository, flags.

## `summary` (type: `string`):

Record count, registries crawled, distinct hosts and flagged count for this run.

# 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 = {
    "registries": [
        "official"
    ],
    "maxItems": 500
};

// Run the Actor and wait for it to finish
const run = await client.actor("thearchitect0x/mcp-registry-scraper").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);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = {
    "registries": ["official"],
    "maxItems": 500,
}

# Run the Actor and wait for it to finish
run = client.actor("thearchitect0x/mcp-registry-scraper").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{
  "registries": [
    "official"
  ],
  "maxItems": 500
}' |
apify call thearchitect0x/mcp-registry-scraper --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,thearchitect0x/mcp-registry-scraper"
        }
    }
}
```

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).
