# Your shipping. Quoted before you buy.

Source: https://corespeed.io/integrations/shippo

Connect Shippo to Claude Code, Codex, Cursor or any MCP agent through CoreSpeed. Your agent validates addresses, quotes a shipment across your carriers, compares the rates and tracks packages with your Shippo API key. Buying or refunding a label is a separate call that charges or credits your Shippo account, and approvals can hold it for a person.

## Set up an agent

Give your agent this line: `set up https://corespeed.io/SKILL.md (read it raw, e.g. with curl)`

It fetches the skill at https://corespeed.io/SKILL.md, adds the CoreSpeed MCP server, signs you in (or up), and keeps the skill for next time. Connect Shippo after setup. Access follows the connected account and its permissions. Create an account: https://app.corespeed.io/sign-up

## See every rate. Buy only what you approve

Ask your agent to quote a parcel across your carriers and recommend a rate. Creating the shipment costs nothing; the label is a separate step.

You ask your agent: "Quote a 2 lb parcel from our Oakland warehouse to a customer in Portland. Compare the rates and recommend one. Do not buy a label."

It calls CoreSpeed:

- `shippo__create_shipment`: ok, 812 ms
- `shippo__list_shipment_rates`: ok, 365 ms

It reads from: Shippo.

## Questions

### Does a test key buy real labels?

No. A shippo_test_ key is free and sees only test data. A shippo_live_ key buys real labels billed to your Shippo account.

### Can my agent buy a label on its own?

Buying a label is a separate call that charges your Shippo account. Approvals can hold that call for a person before it runs. How approvals work: https://corespeed.io/docs/approvals

### Can I limit what the Shippo key can do?

No. Shippo keys carry full account access and cannot be narrowed, so use approvals for the calls that spend.

### Do I have to switch agents?

No. CoreSpeed adds tools to the agent you already use: Claude Code, Codex, Cursor, or another MCP client. Each one signs in once.

### Can my agent access every account in our organization?

No. Access follows your CoreSpeed identity, each connection's visibility, and the app's own permissions. Personal connections stay private.

### Does this work without connecting an account?

No. Connect the app's account first; your CoreSpeed workspace shows what each app needs. The examples on this page use fictional data. All connectors: https://corespeed.io/docs/connectors
