Does mcp server also work on localhost?

Help
1

I am following this tutorial: https://www.youtube.com/watch?v=mJiLiUGh9r8&list=PLD--x9rY3ZL2UGnGGD13YF6NR-H92zogr&index=1

I would like to use the Directus mcp server on a Directus 11.9.3 instance on http://locahost:8056 installation that runs on Docker (following the installation command given on the homepage on Directu).

I did create a token in my personal account and enter it exactly there, where Brian tells us to in the video.

I tried a similar setup with a Directus 10.12 installation that I have running on DigitalOcen.

However, I can’t get either to work. My Claude config file looks like this:

{
    "globalShortcut": "",
    "mcpServers": {
        "Directus_JVDS_local": {
            "command": "npx",
            "args": ["@directus/content-mcp@latest"],
            "env": {
                "DIRECTUS_URL": "http://localhost:8056/",
                "DIRECTUS_TOKEN": "O2jFO4NJiunNcl14b0TIeP2q9URLnpXS",
                "DIRECTUS_PROMPTS_COLLECTION_ENABLED": "true",
                "DIRECTUS_PROMPTS_COLLECTION": "ai_prompts"
            }
        },
        "Directus_JVDS_on_DigitalOcean": {
            "command": "npx",
            "args": ["@directus/content-mcp@latest"],
            "env": {
                "DIRECTUS_URL": "https://jvds.scores-catalog.org/",
                "DIRECTUS_TOKEN": "UwFt0NuUbIKoXSd1vdSiLtbgovPBum87",
                "DIRECTUS_PROMPTS_COLLECTION_ENABLED": "true",
                "DIRECTUS_PROMPTS_COLLECTION": "ai_prompts"
            }
        }
    }
}

And the log file I call via tail -n 20 -F ~/Library/Logs/Claude/mcp*.log look like this:

I restarted Claude 3 times already.

Any idea, what I am doing wrong? Does the Directus mcp have problems with installations that run on Docker? Does this mcp even work on a v10 Directus?
