Common questions

Is MCP Enrichment safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: CLEARBIT_API_KEY, HUNTER_API_KEY, APOLLO_API_KEY, TWILIO_ACCOUNT_SID, TWILIO_AUTH_TOKEN

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 5 days ago, and the latest version (0.1.1) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

@opafex/mcp-enrichment

MCP server for multi-source entity enrichment — company data, contact lookup, email verification, phone validation, and email discovery.

Uses Clearbit, Hunter.io, and Twilio APIs. Works in mock mode with no API keys configured.

Installation

git clone https://github.com/opafex/opafex-mcps.git cd opafex-mcps npm install && npm run build

Omit the env block to run in mock mode.

Returns server metadata: name, version, registered tools, and resources. Added automatically by @opafex/mcp-shared.

Resources

Resource	Description
`enrichment://status`	Provider configuration status (which APIs are active, mock mode)

Mock Mode

When no API keys are configured, all tools return realistic mock data. This is great for development and testing — you can build against the MCP without any API accounts.

Mock mode activates automatically:

Globally when none of CLEARBIT_API_KEY, HUNTER_API_KEY, or TWILIO_ACCOUNT_SID are set
Per-tool when the specific provider key is missing (e.g. if you only set CLEARBIT_API_KEY, company/contact tools use real data while email/phone tools fall back to mock)

Check enrichment://status resource or the server_info tool to see which providers are active.

Environment Variables

Variable	Type	Default	Description
`CLEARBIT_API_KEY`	string	—	Clearbit API key for `enrich_company`, `enrich_contact`
`HUNTER_API_KEY`	string	—	Hunter.io API key for `verify_email`, `find_email`
`TWILIO_ACCOUNT_SID`	string	—	Twilio Account SID for `verify_phone`
`TWILIO_AUTH_TOKEN`	string	—	Twilio Auth Token for `verify_phone`
`APOLLO_API_KEY`	string	—	Apollo.io API key (reserved for future use)
`ENRICHMENT_CACHE_TTL`	number (seconds)	`86400` (24h)	How long to cache enrichment results

Development

npm run build    # Compile TypeScript

npm run dev # Run with tsx (no build needed) npm test # Run tests npm start # Run compiled server

Library Usage

The enrichment service can be used programmatically (not just as an MCP server):

import { EnrichmentService } from '@opafex/mcp-enrichment/service';

import type { CacheProvider } from '@opafex/mcp-enrichment/service';

const service = new EnrichmentService({ clearbitApiKey: 'sk-...', hunterApiKey: '...', });

const result = await service.enrichCompany({ domain: 'stripe.com' });

Custom Cache Provider

The default in-memory cache works out of the box. For Redis, SQLite, or any custom store, implement the CacheProvider interface:

import { EnrichmentService } from '@opafex/mcp-enrichment/service';

import type { CacheProvider } from '@opafex/mcp-enrichment/service';

const redisCache: CacheProvider = { async get(key) { /* ... */ }, async set(key, data, ttlMs) { /* ... */ }, async delete(key) { /* ... */ }, async clear() { /* ... */ }, };

const service = new EnrichmentService({ clearbitApiKey: '...', cache: redisCache, });
