Cant enable mcp server from custom catalog

[presidenten]

Problem: I cant enable mcp server from custom catalog with docker cli

How to recreate:

❯ docker --version
Docker version 28.4.0, build d8eb465

Run

git clone https://github.com/theNetworkChuck/docker-mcp-tutorial.git
cd docker-mcp-tutorial/examples/dice-roller
docker build -t dice-mcp-server .

create a file catalog_entry.yaml

registry:
  dice:
    description: "Comprehensive dice rolling for tabletop games and randomization"
    title: "Dice Roller"
    type: server
    dateAdded: "2025-01-24T00:00:00Z"
    image: dice-mcp-server:latest
    ref: ""
    readme: ""
    toolsUrl: ""
    source: ""
    upstream: ""
    icon: ""
    tools:
      - name: flip_coin
      - name: roll_dice
      - name: roll_custom
      - name: roll_stats
      - name: roll_advantage
      - name: roll_disadvantage
      - name: roll_check
      - name: roll_initiative
    metadata:
      category: productivity
      tags:
        - gaming
        - dice
        - randomization
        - dnd
        - tabletop
      license: MIT
      owner: local

then create custom catalog and add the mcp server

docker mcp catalog create custom

docker mcp catalog add custom dice catalog-entry.yaml

all good so far, I can run show and see the server listed

❯ docker mcp catalog show custom
dice: Comprehensive dice rolling for tabletop games and randomization

But this is as far as I get. I cant enable it

❯ docker mcp server enable dice
server dice not found in catalog

❯ docker mcp server enable custom/dice
server custom/dice not found in catalog

❯ docker mcp server enable --catalog custom dice
unknown flag: --catalog

Usage:  docker mcp server enable

Run 'docker mcp server enable --help' for more information

How do I enable it using docker cli?

I have exactly the same problem

This was definitely a bug. We just released a fix for this in v0.19.0 but you'll only be able to try it out by building locally (#138).

When running docker mcp server enable, we'll be searching all of the catalogs by default.

Let me know if that fixes it for you!

@slimslenderslacks - it works! Thanks

@slimslenderslacks Also confirming that it is fixed in 0.19.0.

Thanks for quick fix!
