Connect Claude Code

Connect the Claude Code CLI to your SellerJar data using an API key. This is a config-based connection: no browser approval step is needed once the key is generated.

Before you start​

  • A SellerJar account (MCP access is available on all accounts)
  • Claude Code installed
  • A SellerJar MCP API key (see Step 1)

Step 1: Generate your MCP API key​

In SellerJar, go to Settings → Account Settings → MCP API Key and click Generate API Key. The key is shown once: copy it now. If you lose it, you'll need to rotate to a new one.

Step 2: Add the SellerJar MCP server​

Run:

claude mcp add --transport http --scope user sellerjar https://api.sellerjar.com/mcp --header "X-SELLERJAR-MCP-KEY: <your-key>"

Replace <your-key> with the key from Step 1. --scope user makes SellerJar available in every project; drop it if you only want the current project.

Step 3: Verify the connection​

Run:

/mcp

You should see sellerjar listed as a connected server with its tools available.

Step 4: Test it​

Ask Claude Code:

List my SellerJar profiles.

This calls the list_profiles tool and confirms the key and authorization are working end to end.

Troubleshooting​

ProblemCause / fix
401 / unauthorizedYour key may have been rotated or disabled from Account Settings, generate a new one and update the --header value.
Server not found / can't connectConfirm the URL is exactly https://api.sellerjar.com/mcp and the header name is exactly X-SELLERJAR-MCP-KEY.

Since Claude Code connects via API key, revoking access is done by rotating or disabling the key in Account Settings, not from the "Connected AI clients" card, which only lists OAuth connections.
