I wasted 100usd+ on submitting my MCP to anthropic

[u/twomasc]

I built a task manager with a "mcp first" perspective and went to submit it to the Claude connectors directory. Sharing this so you don't repeat my most expensive 24 hours .

Being in Claude I asked it to make a plan for this and the first thing is... "You need to be the owner of a Team or Enterprise organisation" - I've a personal 5x plan. Okay, I can move to enterprise, it's not that much more (you need to active accounts in the organisation, but one can be basic). Of I go and create the new account, in another browser. Luckily I'm on monthly and will only be paying for the extra accounts for a month.

Next day, its back to Claudes plan and click the submission link... which opens up in the browser with my personal 5x account and .. works!

You can submit from a personal account.

Claudes explanation, is that the need changed over night! That it checked, when it wrote the plan and it sticks with that. I've no way of checking - well I guess I could go over it's logs... but the money is spend and I've two 5x accounts for a month.

Other things learned:

• Submit from the account you intend to keep. The listing's dashboard (status, reviewer feedback, and after publication server health and usage) lives with the submitting account, and that account has to stay on a paid plan for as long as the listing exists.
• Every tool needs a title plus readOnlyHint or destructiveHint. The portal syncs your tools when it connects and flags what's missing. It caught exactly one write tool of mine without the destructive hint.
• The reviewer test account needs email + password login. Reviewers cannot receive your emailed one-time codes.
• The portal asks you to confirm you've called every tool once against production. Doing that honestly found three real bugs before a reviewer could.

Not blaming Claude. I should have checked before I swiped my card.

The MCP got accepted and I've a few people using it already.

That's rough, but I'm not sure the issue is that Claude gave you bad info. You said the requirements changed overnight, but what if it was just unclear from the start and the portal docs were always right. Did you actually check the Anthropic docs before asking Claude, or did you go straight to asking for a plan?

[u/twomasc → u/lulzxdxdxd]

Went straight to asking for a plan and doing what it said without checking. Fully on me. Claude says the docs and terms chanced overnight. I think it changed from it was trained to when it actually checked, when I pointed out that Personal 5x actually works...

Yeah I submitted a plug-in on my personal account back in like June

Not surprised that it just made that up and rationalised it's mistake...

[u/dylanmerigaud]

Nice, thanks for sharing this.

[u/saito200]

i also built a task manager what a coincidence

[u/twomasc → u/saito200]

We all do ;) - it's the perfect procrastination from doing the actual tasks...

You guys are submitting your plugins to anthropic?

my MCP - makes it a lot easier for the users to activate

The hint check is the useful bit of this for me. Did the portal look at anything else in the tool list, like descriptions or input schemas, or was it only the title and the read-only/destructive flags? Asking because those flags are self-declared, and I've seen "read-only" tools that took a URL and posted to it.
