Gemini CLI + Wahlu

Post to Pinterest from Gemini CLI with Wahlu

Connect Gemini CLI to Wahlu once, then plan, draft and schedule posts for Pinterest business accounts, posting to the board you pick for each Pin from the Gemini CLI terminal. Every schedule can wait for your approval.

Ask Gemini CLI for Pinterest posts

Example prompts and the steps to expect. These are illustrations, not recorded conversations.

Example prompt

“Read the README in this project and create a Pin for the release with a title and a link to the docs. Ask me which board, then hold it for review tomorrow at 9am.”

Example prompt

“Create a carousel Pin from the screenshots in docs/launch for the README in this project, with alt text for each, then run a readiness check.”

Example prompt

“List my Pinterest boards and check what's already scheduled there this week before you draft a Pin about the README in this project.”

What Wahlu does on Pinterest

Gemini CLI works through Wahlu's tools, so it can set the Pinterest options Wahlu supports.

Pinterest settings on a draft

Board
Required. Your agent lists the account's boards and asks which one to use.
Section
An optional section of the board.
Title and link
A title up to 100 characters and the page the Pin opens.
Alt text
A description of the image for screen readers.

Pinterest asks that you choose each Pin yourself, so confirm each Pin; looping queues, Autopilot and flows don't post to Pinterest. Only business accounts can connect.

The tool calls, in order

  1. 01

    list_targetsFinds the brand's connected Pinterest account and checks it's ready.

  2. 02

    upload_media_from_file, import_media_from_url or list_mediaBrings in the image or video, or picks one from your media library.

  3. 03

    create_draftCreates the draft with its caption and pinterest_settings, such as the post type.

  4. 04

    preflight_draftChecks the draft against Pinterest's rules without changing it.

  5. 05

    create_schedulePuts it on the calendar at pending_review, held for your approval.

Pinterest limits to know

Wahlu checks these before a post is scheduled, so the agent finds out early.

Getting images and video to Pinterest

The local server can upload a file straight from your computer with upload_media_from_file, so screenshots and videos in your project don't need a public link.

Connect Gemini CLI to Wahlu

Set this up once and Gemini CLI can work on every network you've connected, not just Pinterest.

  1. 1

    In the Wahlu app, create an API key under Settings → API Keys in your workspace, with only the permissions and brands you need.

  2. 2

    Add export WAHLU_API_KEY=your-key to your shell profile, with your key, and open a new terminal.

  3. 3

    Add the Wahlu configuration to ~/.gemini/settings.json. If the file already has settings, add wahlu inside its mcpServers object.

  4. 4

    Start a new Gemini CLI session and run /mcp to check that wahlu is connected and its tools are listed.

Checked against the Gemini CLI docs on 27 September 2026. Menus can change; if a step doesn't match what you see, follow the vendor's current instructions.

~/.gemini/settings.json
{
  "mcpServers": {
    "wahlu": {
      "command": "npx",
      "args": ["-y", "@wahlu/mcp-server@latest"],
      "env": {
        "WAHLU_API_KEY": "$WAHLU_API_KEY"
      }
    }
  }
}

Gemini CLI replaces $WAHLU_API_KEY with the value from your shell, so the key isn't saved in the settings file. You can also add the same configuration to a project's .gemini/settings.json to use Wahlu in that project only. Available local tools depend on the installed version. Check the local MCP server notes for its Node.js requirement and tool availability.

You stay in control.

Every Wahlu plan includes agent access, through MCP and the API. You choose the workspace, brands and permissions each connection gets, and can disconnect it at any time.

Held until you approve

Agents create schedules at pending_review unless you've told them to publish. A held schedule can't publish until you approve it in Wahlu or ask an agent with Publishing permission to approve it.

Publishing is its own permission

Publishing is separate from Manage your schedule. Leave it unticked and nothing your agent schedules can go out on its own.

Checked before it's scheduled

preflight_draft reports anything that would stop a post, such as media the network won't accept or a caption that's too long, without changing anything.

Some things stay in the app

Use the app for queues, draft media and platform settings, and connecting social accounts. Agents can change the name or caption of an unused draft and approve held schedules with the right permissions.
