The Smart Send plugin lets you book shipments, compare rates, find service points, and track parcels by chatting with Claude. It bundles two things in one install: a connection to the Smart Send MCP server, so every action runs against your real account and carrier connections, and the Smart Send Skill, so Claude knows how to use those tools well.
The plugin works across Claude Code , Claude Desktop , and Claude on the web . The commands below show the Claude Code flow; in Claude Desktop and Claude Web you add the same plugin through the app’s plugin settings.

​
Before you start

​
Install the plugin

In Claude Code, run these commands in order: 
/plugin marketplace add smartsendio/claude-plugin
/plugin install smartsend@smartsend
/reload-plugins
In Claude Desktop and Claude Web, open the app’s plugin settings and add the same Smart Send plugin from the smartsendio/claude-plugin marketplace.
  • The first command registers the Smart Send repository as a plugin marketplace.
  • The second installs the plugin to your user scope, so it’s available across all your projects.
  • The third activates it without restarting Claude Code.

​
Sign in

The plugin uses OAuth — there are no API keys to copy around. The first time you use a tool, Claude asks you to sign in to Smart Send and approve access. Log in with your existing account, approve, and you’re connected.

​
Try it

Ask Claude in plain language. For example:
  • “Book a 2 kg parcel to this customer with PostNord home delivery.”
  • “Find me the three closest GLS parcel shops to postal code 8000 in Denmark.”
  • “Where is order #1042? It was supposed to arrive yesterday.”
  • “Validate these 40 addresses from my CSV before I import them.”
Claude collects the details it needs — addresses, parcel dimensions, and service selection — and confirms with you before booking anything.

​
Keep it up to date

To update the plugin to the latest version: 
/plugin marketplace update smartsend
/reload-plugins
