Post to DEV.to from Gemini CLI

Gemini CLI 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 Gemini CLI

Add PostDelegate to Gemini CLI. Add the server to ~/.gemini/settings.json as below. Sign in with PostDelegate when Gemini CLI prompts you.
~/.gemini/settings.json
```
{
  "mcpServers": {
    "postdelegate": {
      "url": "https://app.postdelegate.com/mcp-oauth-dynamic"
    }
  }
}
```
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 Gemini CLI for a draft. Describe the post in plain words. Gemini CLI checks your DEV.to channel's rules, creates the post and sends back a preview link.

Teach Gemini CLI the posting rules

Save PostDelegate’s AGENTS.md in your repository and point to it from your GEMINI.md, so Gemini CLI follows the posting rules there. Agent files has the steps.

What to ask Gemini CLI

Mention any DEV.to setting in plain words and Gemini CLI fills it in. Gemini CLI can also read text files in your project, such as a changelog or a draft in Markdown.

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.
Turn docs/how-we-test.md into a DEV.to article with up to four tags, saved as a draft.

What Gemini CLI 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 Gemini CLI can fill in

Questions

Will Gemini CLI 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 Gemini CLI can ask you before it schedules or deletes anything.

Do I need an API key to connect Gemini CLI?

No. Gemini CLI 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 Gemini CLI with PostDelegate?

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

Can Gemini CLI 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. 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.
