How do I connect PostlyBee to DeepSeek Harness?

DeepSeek Harness connects to MCP servers through its official MCP client plugin, configured as a Cordis overlay.

  1. 1

    Create a scoped token

    Start your 7-day free trial, connect your channels, and create a pbk_ token with the mcp:read or mcp:write scope in Settings → Public API.

  2. 2

    Add the PostlyBee overlay

    Save the overlay with your workspace ID and start dsh with --patch, or merge it into your user patch file.

  3. 3

    Ask DeepSeek to post

    Open the dsh Web UI, pick a workspace, and describe the post. PostlyBee tools appear as mcp__postlybee__*.

MCP server URL

https://api.postlybee.com/mcp

Save this as postlybee.cordis.yml. The header reads your token from the environment, so the file never holds the secret.

  1. 1Replace YOUR_WORKSPACE_ID with your PostlyBee workspace ID and save the file.
  2. 2Export POSTLYBEE_API_TOKEN with your pbk_ token in the shell that runs dsh.
  3. 3Start dsh with npx @deepseek-ai/dsh web --patch "$PWD/postlybee.cordis.yml".
  4. 4Ask DeepSeek to list your PostlyBee channels to check the connection.
- insert:
    - id: mcp-postlybee
      name: '@deepseek-ai/dsh-mcp-client'
      config:
        serverName: postlybee
        transport: streamable-http
        url: https://api.postlybee.com/mcp/workspaces/YOUR_WORKSPACE_ID
        headers:
          Authorization: !!js '`Bearer ${process.env.POSTLYBEE_API_TOKEN}`'

Capabilities

What can DeepSeek do with PostlyBee?

DeepSeek Harness runs agents that read your workspace, run commands, and call MCP tools. PostlyBee adds social publishing.

  • Write from your workspace

    DeepSeek reads files in the selected workspace, such as a changelog, and turns them into posts.

  • Follow each platform’s rules

    It loads each channel’s post rules and settings from PostlyBee before it writes.

  • Schedule or save drafts

    Schedule posts to one or several channels, or save drafts for your team to review.

  • Fill open slots

    Find the next free slots in your posting schedule and place posts in them.

  • Check the calendar

    List drafts, scheduled, published, and failed posts for any date range.

  • Read analytics

    Pull account and post analytics and ask DeepSeek what to change.

How it connects

How DeepSeek Harness talks to PostlyBee

The official @deepseek-ai/dsh-mcp-client plugin connects to PostlyBee’s hosted MCP server over Streamable HTTP and exposes its tools as mcp__postlybee__<tool>. Tool names stay stable, so permission rules and session history survive restarts.

The client authenticates with a static header, so use a pbk_ token bound to one workspace. Give it mcp:read for research and reporting, and mcp:write only if DeepSeek should schedule posts.

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. DeepSeek Harness needs your own DeepSeek API key.

How is access secured?

The token is bound to one workspace and read from the environment, so it never sits in the overlay file. Revoke it any time in PostlyBee.

Something not working?

Check that POSTLYBEE_API_TOKEN is set in the shell that starts dsh and that the token has an mcp scope for the workspace in the URL.
