Post to DEV.to from Claude

Claude drafts it. You approve it. PostDelegate posts it.DEV.to: Markdown articles with tags, a cover and a canonical URL.

How to post to DEV.to from Claude

Add PostDelegate to Claude. In Claude open Settings, then Connectors, then Add custom connector. Name it PostDelegate and paste the server URL below. Choose Add, then Connect, sign in to PostDelegate and click Authorize.
Server URL
```
https://app.postdelegate.com/mcp-oauth-dynamic
```
Custom connectors depend on your Claude plan and, on team plans, on what your organisation allows.
Connect DEV.to in PostDelegate. In your DEV Community account settings, under Extensions, generate an API key. DEV owns that screen, so its wording may change.
Ask Claude for a draft. Describe the post in plain words. Claude checks your DEV.to channel's rules, creates the post and sends back a preview link.

Teach Claude the posting rules

Add the PostDelegate skill to Claude so it knows the posting rules before it writes: download the skill zip and upload it under Customize, then Skills, with code execution turned on. Agent files has the steps.

What to ask Claude

Mention any DEV.to setting in plain words and Claude fills it in. Start with something harmless, like asking which channels you have.

Draft a DEV.to article from this outline, with the tags javascript and webdev, and a canonical URL pointing to our blog.
Schedule my DEV.to article for Tuesday at 15:00 under our organization, with the cover image from my media library.

What Claude can do on your DEV.to channel

Check the rules first. Before writing, it reads your DEV.to channel's length limit and required settings.
Draft, schedule or post. It creates a draft, a scheduled post or an immediate post, and runs the same checks as the app.
Use your media. It attaches files from your media library or adds one from a public link.
Review and fix. It lists what is scheduled, changes the DEV.to settings of a post that has not gone out, and deletes posts you no longer want.

DEV articles are written in Markdown, and PostDelegate's composer switches to a Markdown editor when you select a DEV channel. You can set the title, up to four tags, a cover image, an optional organization and a canonical URL, then choose when the article goes out.

DEV.to settings Claude can fill in

Setting	Notes
Title	Required, at least 2 characters.

Tags	Up to 4, picked from DEV's tag list.

Before you start

DEV publishes the article straight away when the post goes out. Keep a draft in PostDelegate to hold it back.

Questions

Will Claude publish to DEV.to without asking me?

Not unless you ask it to. Ask for a draft and the post waits on your calendar until you schedule it, and your workspace's approvals apply as usual. Tools that change data are marked as such, so Claude can ask you before it schedules or deletes anything.

Do I need an API key to connect Claude?

No. Claude signs in with your PostDelegate account through your browser. An API key is only for clients that cannot sign in, as described in MCP clients.

Does it cost extra to use Claude with PostDelegate?

No. The MCP server is on every plan, and Claude runs on your own Claude account, so PostDelegate never charges for AI. Every plan starts with a 7-day free trial with no card.

Can Claude attach images or video to a DEV.to post?

It can use files already in your media library, or add one from a public link. It cannot fetch files from your computer, so upload those in the app first, or through the upload widget where Claude shows it. See MCP tools.

Can I set a canonical URL on a scheduled DEV.to article?

Yes. Canonical URL is an optional setting. Use it when the article first appeared on another site. DEV rejects a canonical URL that another DEV article already uses.

Will DEV keep my article as a draft until I publish it?

No. DEV publishes the article straight away when the PostDelegate post goes out. To hold an article back, keep it as a draft in PostDelegate rather than relying on a draft on DEV.
