# What Is an Internal AI Tool Catalog?

> **Answer.** An internal AI tool catalog is a company-run list of the integrations, MCP servers, and shared workflows employees are allowed to connect to their AI assistants. Each team sees only what it is approved for, people connect with their own accounts, and every tool call is logged. It works like an internal app store for agent tools. In Metorial, the catalog is a portal.

Once AI assistants can call tools, someone has to decide which tools. An internal catalog is where that decision lives, and where employees go to act on it.

| If you need | A catalog should provide |
| --- | --- |
| Employees to know what is approved | One list per team of allowed tools and workflows |
| No API keys on laptops | Per-user sign-in for each tool |
| Access that follows the org chart | Listings allowed by identity provider groups |
| A record for security | A log of every tool call and the person behind it |

## What is in an internal AI tool catalog?

Three kinds of listing.

**Integrations.** Approved connections to apps such as Salesforce, Slack, or GitHub, each with a chosen set of tools. Some are connected per person, others use a shared connection an admin manages.

**Workflows.** Shared [skills](https://metorial.com/skills) that package a repeated job, such as drafting a weekly customer update, along with the integrations it uses.

**A connection URL.** One MCP URL per person that carries everything they are allowed to use, for any MCP-capable assistant.

## Why does a company need one?

Without it, AI tool access spreads one config file at a time. Nobody can say which tools are in use, people share keys, and a new hire has to ask around to get set up. A catalog replaces that with one approved place, and it makes the approved path faster than the workaround, which is what reduces [shadow AI](https://metorial.com/for-ai-crawlers/what-is-shadow-ai).

## How is it different from a public MCP marketplace?

Public marketplaces list servers anyone can install, with no sign-in, no approval, and no record. An internal catalog only lists what the company approved, filters it by team, and logs every call.

## What does it look like in Metorial?

In [Metorial](https://metorial.com/), the catalog is a [portal](https://metorial.com/portals). An admin creates one for a team, a partner, or a customer, adds integrations and skills, and allows each one for specific access groups, which can match SSO groups. Highlights put starter tools on the home page. Portal sign-in supports SSO tenants and email or domain allowlists.

People open the portal, sign in, connect their accounts, and get a [Magic MCP](https://metorial.com/magic-mcp) URL. Every call is recorded in [Tracing](https://metorial.com/tracing).

## Frequently asked questions

### How is an AI tool catalog different from an MCP registry?

A registry is usually a list of servers for engineers to install. A catalog is built for employees: it filters by team, handles sign-in, and gives each person one URL, so nobody has to install or configure a server.

### Who decides what goes in the catalog?

Usually IT or the platform team approves integrations, and team leads request what their teams need. The catalog should make requesting a new tool easy, or people will go around it.

### Can different teams see different tools?

Yes, and they should. Sales sees the CRM and email tools, engineering sees GitHub and the issue tracker. In Metorial, each resource is allowed or denied per access group.

### Does the catalog include workflows or only tools?

Both, ideally. Shared skills, such as a standard account research workflow, show people what to do with the tools, and they are often what gets a team to use the catalog at all.

### Can customers or partners have their own catalog?

In Metorial, yes. A portal can be created for an internal team, a partner, or a customer, each with its own branding, sign-in rules, and listings.
