Schedule social media posts with Grok Build

Add PostlyBee to Grok Build with one command. Grok can then turn your commits, docs, and release notes into posts and schedule them to your social channels without leaving the terminal.

  • One command, then an OAuth sign-in from the /mcps tab
  • Already set up PostlyBee in Claude Code? Grok Build picks it up
  • Add the PostlyBee skill to upload images and videos from your repo

$0 charged today, cancel anytime. MCP is included in every paid plan.

How do I add PostlyBee to Grok Build?

Grok Build keeps MCP servers in ~/.grok/config.toml. The grok mcp add command writes the entry for you.

  1. 1

    Connect your social channels

    Start your 7-day free trial and connect the accounts Grok should post to, such as X, LinkedIn, or Bluesky.

  2. 2

    Add the PostlyBee server

    Run grok mcp add, then sign in from the /mcps tab in Grok Build and approve a workspace.

  3. 3

    Ask Grok to post

    Point Grok at a file or a commit range and ask for a post. It shows the draft before it schedules.

MCP server URL

https://api.postlybee.com/mcp

Best on your own machine. Grok Build stores the sign-in in ~/.grok/mcp_credentials.json and reuses it.

  1. 1Run the command below in your terminal.
  2. 2Start grok and open /mcps. Select postlybee and press i to sign in to PostlyBee in the browser.
  3. 3Ask Grok to list your PostlyBee channels. If something is off, run grok mcp doctor postlybee.

Capabilities

What can Grok Build do with PostlyBee?

Grok Build works in your repository. PostlyBee lets it turn what you ship into scheduled posts.

  • Write from your code

    Grok reads diffs, docs, and changelogs and writes posts that match what actually changed.

  • Post to developer channels

    Schedule X and Bluesky threads, Dev.to articles, and LinkedIn posts from one prompt.

  • Follow each platform’s rules

    Grok loads each channel’s post rules and settings before it writes.

  • Fill open slots

    Find the next free slots in your posting schedule and spread a batch of posts across them.

  • Upload from disk

    With the PostlyBee skill, Grok attaches screenshots and demo videos from your repo.

  • Read the results

    Pull account and post analytics to see which release posts landed.

Claude Code compatible

Already use PostlyBee in Claude Code?

Grok Build reads Claude Code plugins, skills, and MCP servers alongside its own .grok configuration, with no extra setup. If you installed the PostlyBee plugin or skill for Claude Code, Grok Build can use it too.

You only need to sign in to PostlyBee again from /mcps, because Grok Build keeps its own OAuth sign-ins.

# In Claude Code, once:
/plugin marketplace add bigwhaleltd/postlybee-agent
/plugin install postlybee@postlybee

Pricing and security

How much does it cost?

MCP access is included in every paid PostlyBee plan, starting from $9.99 per month, with a 7-day free trial. Grok Build itself needs an xAI account with access to it.

How is access secured?

OAuth sign-ins and API tokens are scoped to one workspace. Keep tokens in environment variables so they never land in config.toml.

Something not working?

Run grok mcp doctor postlybee to check the connection, and sign in again from /mcps if the server needs authentication.
