How to connect MagicPost to Claude

Connect MagicPost to Claude and you can read your metrics, write posts in your style, schedule them and work your leads, all by asking in plain language.

Two minutes. On the web, MagicPost connects over OAuth: nothing to create, you sign in and approve. Claude Desktop uses an API key instead: see How to create an API key.

Claude on the web

1. Go to Settings → Connectors and click Add custom connector.

2. Name it MagicPost, and set the URL to https://mcp.magicpost.in/mcp.

3. Click Connect. A MagicPost page opens: sign in if asked, read what Claude is requesting (create, schedule and publish LinkedIn posts; read your drafts and stats), and click Authorise.

Behind the scenes, this creates an API key on your account. You can see it, and revoke it, in your account settings, tab API & MCP. Revoking it cuts Claude off instantly.

Custom connectors require a paid Claude plan (Pro, Max, Team or Enterprise).

Claude Desktop

1. Open your Claude config file.

On macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

If the file does not exist, create it.

2. Add MagicPost:

{

  "mcpServers": {

    "magicpost": {

      "command": "npx",

      "args": [

        "-y",

        "mcp-remote",

        "https://mcp.magicpost.in/mcp",

        "--header",

        "Authorization:Bearer mp_YOUR_TOKEN_HERE"

      ]

    }

  }

}

Replace mp_YOUR_TOKEN_HERE with your key. If you already have other MCP servers in the file, add magicpost alongside them inside mcpServers. Do not create a second mcpServers block.

3. Fully quit Claude and reopen it.

On macOS that means Cmd+Q, not just closing the window. This is the step everyone skips, and it is why the tools do not show up.

MagicPost's tools now appear in Claude's tools menu.

Try it

Ask Claude something you would otherwise click through:

• "How did my LinkedIn posts perform over the last 30 days?"

• "Draft a post about [topic] in my writing style and save it as a draft."

• "What's scheduled this week?"

• "Which of my leads are an excellent fit and haven't been contacted?"

Two of those have a walkthrough of their own: reading your LinkedIn analytics inside Claude and scheduling LinkedIn posts from a Claude conversation.

You never name the tools. Claude picks them.

When it does not work

The tools do not appear. You did not fully quit Claude. Cmd+Q, reopen.

Authentication errors. Check you copied the whole key, and that the header reads Authorization:Bearer mp_..., with the Bearer prefix included.

Nothing happens at all. Check the JSON is valid: a trailing comma or a missing brace stops Claude loading the file entirely, silently.

It worked yesterday, not today. The key may have been revoked. On the web, reconnect; on Desktop, create a new one.

MagicPost refuses the authorisation. API and MCP access needs a Creator plan or above, or an active trial. Upgrade, then connect again.

Good to know

Claude can spend your credits: generating a post uses a generation credit, launching a lead detection uses Leads credits, exactly as in the app. It normally shows you what it is about to do and waits. Read what it proposes before you approve it.

FAQ

Which plan do I need?

Creator and above. Leads tools also need the Leads module.

Does this work on Windows?

Yes. The config file lives at %APPDATA%\Claude\claude_desktop_config.json; the content is identical.

What can Claude actually do?

30 tools: posts, scheduling, media, analytics, writing style, inspiration, leads, team. See What is MCP, and what can I do with it?
