Empowering Enterprise AI with Custom MCP Catalogs and Profiles

Introduction

Managing the growing ecosystem of AI tooling can be a challenge for enterprises. The Model Context Protocol (MCP) offers a standardized way to connect AI models with external tools, but ensuring teams use approved, secure servers is critical. Today, we’re excited to announce the general availability of Custom MCP Catalogs and MCP Profiles—two complementary features that transform how organizations package, distribute, and manage MCP servers. Custom Catalogs allow teams to curate and distribute trusted server collections, while Profiles empower individual developers to build, run, and share portable configurations. This article walks through creating a custom catalog step by step, introduces Profiles, and explains how these tools accelerate enterprise MCP adoption.

Why Custom Catalogs Matter

As organizations adopt MCP, a common pain point emerges: teams need a single source of truth for MCP servers. Without curation, developers waste time searching the open internet for servers or accidentally use unvetted tools. Custom Catalogs solve this by letting organizations publish approved lists of MCP servers—including internally built ones—so team members can discover and use them with confidence. These catalogs can reference servers from Docker’s MCP Catalog, community sources, or proprietary servers, blending flexibility with control.

Introducing MCP Profiles

While catalogs handle curation, MCP Profiles address portability. A Profile is a named, portable grouping of MCP servers that a developer can create and share across projects or teams. Profiles make it easy to package a specific set of tools for a task—like data analysis or API testing—and reuse them consistently. They also lay the groundwork for future enhancements, such as profile inheritance or versioning.

Building a Custom Catalog: Step by Step

Let’s walk through the process of creating a custom catalog that includes both a server from the Docker MCP Catalog and a custom-built server. We’ll use the CLI and Docker Desktop, though most user-facing features are also available in the GUI.

Step 1: Create and Push a Custom MCP Server

Our example server is roll-dice (GitHub repository). It’s a simple MCP server that communicates over stdio and is packaged as a Docker image. We’ve already built and pushed the image to Docker Hub under roberthouse224/mcp-dice.

To describe the server, create a YAML file named mcp-dice.yaml with the following metadata:

name: roll-dice
title: Roll Dice
type: server
image: roberthouse224/mcp-dice@latest
description: An MCP server that can roll dice

Step 2: Assemble the Catalog

Now create a catalog that includes your custom server alongside a server from the Docker MCP Catalog. Use a catalog descriptor (e.g., my-catalog.yaml) to list the servers. For the Docker MCP Catalog server, you can reference its official name. For the custom server, point to your local YAML file.

Source: www.docker.com

Example catalog descriptor:

catalog:
  - name: roll-dice
    source: local:./mcp-dice.yaml
  - name: fetch
    source: docker:demos/fetch:latest

Replace the image IDs with your own Docker Hub credentials as needed.

Step 3: Distribute and Import the Catalog

Save your catalog YAML file and share it with your team (e.g., via a Git repository or internal registry). Team members can then import the catalog into Docker Desktop or use the CLI command:

docker mcp catalog import my-catalog.yaml

Once imported, the curated servers appear in Docker Desktop’s MCP interface, ready to be used by developers.

Using Catalogs and Profiles Together

Custom Catalogs and Profiles complement each other. A team lead might create a catalog of approved servers for the organization, while each developer builds a Profile that selects a subset of those servers for their current project. Profiles can reference servers from the catalog, ensuring consistency while allowing personalization. For example, a data science Profile might include roll-dice and a “math-tool” server from the catalog.

Practical Use Cases

Enterprise onboarding: New developers can import the company’s catalog and immediately access all sanctioned MCP servers.
Multi-team consistency: Different teams can maintain their own catalogs while adhering to a central security policy.
Portable AI workflows: A Profile created for a specific task (e.g., “daily report generation”) can be shared across colleagues.

Looking Ahead

The current release focuses on curation and portability, but we’re already exploring advanced features like profile inheritance, versioned catalogs, and integration with CI/CD pipelines. Custom Catalogs and Profiles are foundational blocks for a more organized, secure, and efficient MCP ecosystem.
