Piloxa in Claude

Add it as a connector (tested: paying customers arrive this way)

Open claude.ai/settings/connectors.
Choose to add a custom connector.
Name it Piloxa and paste https://piloxa.com/mcp as the URL. There is no sign-in step.
In a chat, ask “Is this letter ready to send by Certified Mail?” or “Send this certified.”

Claude then uses the tools on the MCP page. It can check and price a letter and prepare it; you approve and pay on Piloxa’s page.

Not yet tested by us, so not described here

Calling Piloxa from the Claude API’s MCP connector or from the Claude Agent SDK. Both should work against any remote MCP server, but we list an integration only once we have run it.

What no integration can do

Mail or charge anything. Nothing is printed, mailed or charged until a person reviews the exact document, the recipient and the total, and approves and pays on the review page. An assistant can check, quote and prepare; it cannot send.
Read a person’s past letters anonymously. Status answers only for letters prepared in the same session.
Decide a legal deadline. A deadline is the person’s to state; Piloxa only notices that a letter mentions one.
