What Wahlu does on Bluesky

Claude works through Wahlu's tools, so it can set the Bluesky options Wahlu supports.

Bluesky settings on a draft

Post type
Text, image or video.
Alt text
A description of each image or video for screen readers.

Agents can post Bluesky threads of up to 25 posts with thread_parts. Quote posts aren't available. Video needs a verified email on Bluesky. Bluesky follower and post numbers show in the app on paid plans; agents can't read them yet.

The tool calls, in order

  1. 01

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

  2. 02

    import_media_from_url, upload_media 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 bluesky_settings, such as the post type.

  4. 04

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

  5. 05

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

Bluesky limits to know

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

Getting images and video to Bluesky

The hosted connection can't open files on your computer. Give the agent a public link to import, pick from your brand's media library, or attach an image the agent can pass on as data. For video, a public link or your media library is usually easiest.

Connect Claude to Wahlu

Set this up once and Claude can work on every network you've connected, not just Bluesky.

  1. 1

    Open Customize → Connectors.

  2. 2

    Click +, then Add custom connector.

  3. 3

    Name it Wahlu and paste https://mcp.wahlu.com/mcp as the remote MCP server URL. Leave Advanced settings empty.

  4. 4

    Click Add, then Connect, and sign in to Wahlu.

  5. 5

    In a chat, turn Wahlu on from the + button under Connectors.

Checked against the Claude Help Center on 24 September 2026. Menus can change; if a step doesn't match what you see, follow the vendor's current instructions.

The same steps work on claude.ai and in Claude Desktop. On Team and Enterprise plans, an organisation owner first adds the connector in Organization settings → Connectors (Add, then Custom → Web); members then click Connect next to it in Customize → Connectors. Free plans allow one custom connector.

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.
