Your agent never holds the credential. 100,000 calls a month free." canonical: https://actionlake.com/connectors/easypost updated: 2026-10-22 --- Connectors · Commerce # EasyPost MCP server for AI agents. actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to EasyPost and the rest of your systems. It gives your agent 126 EasyPost actions (57 reads, 46 writes and 23 that wait for a confirmation) and holds the EasyPost credential itself, so the agent never does. It paces EasyPost's limits and records every call. [Connect EasyPost free](https://actionlake.com/console?start=sandbox) [See pricing](https://actionlake.com/pricing) 100,000 free calls a month. No card, no email, no password: press Start a free sandbox on the next screen and keep the key it shows you. `claude mcp add --transport http actionlake https://connect.actionlake.com/mcp` the first call ``` do { action: "easypost.users.children.list", intent: "check which EasyPost account is connected" } # List child users · read · 1 upstream call ``` - 126 actions in one signed file - 57 read look, never change - 46 write create and update - 23 wait for a yes destructive, confirmed first Set up ## Connect EasyPost in three steps. 1. 01 ### Add actionlake to Claude. Run the command once in Claude Code; its consent page can create a free sandbox: 100,000 calls a month, no card. In the Claude app, add a custom connector with the URL below and paste your key on the consent page. Creating a new sandbox from the Claude app is not yet tested by us. `https://connect.actionlake.com/mcp` 2. 02 ### Connect EasyPost. Username and secret. No consent screen: your agent can connect it for you, but the key then passes through your chat. To keep it out of the model's context, paste it in the console instead. actionlake stores what you paste write-only, sealed under your tenant's key. - `api_key` EasyPost API key (Dashboard > Account Settings > API Keys) ``` account { op: "connections.requirements", service: "easypost" } # free: exactly what to paste, and what is found for you ``` 3. 03 ### Make the first call. Check before a write. Ask in plain words; Claude picks the action. Before anything changes, `check` validates the call and prices it, for free. ``` do { action: "easypost.users.children.list" } # list child users · read · 1 upstream call check { action: "easypost.users.create", input: { … } } # free: inputs, permissions, cost and confirmations, nothing sent ``` EasyPost at a glance **Sign-in** Username and secret.

The free call account { op: "connections.requirements", service: "easypost" } lists exactly what to paste. **Can an AI agent delete or change things in EasyPost?** Only if its key allows it, and only with an explicit confirmation. 23 EasyPost actions are destructive, including delete a child user, delete an API key and delete a webhook. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it. **Will an AI agent use up my EasyPost API limit?** actionlake paces every call to the limits in the EasyPost service file: 600 calls a minute per connection. Repeated reads are answered from cache (49 EasyPost actions can be), which never reaches EasyPost. **What does an EasyPost action cost?** One upstream call, the only unit actionlake bills. A list that pages bills one call per page (126 EasyPost actions page). Cache hits, searches, dry runs and calls EasyPost refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000. **Which EasyPost API does it cover?** The EasyPost API v2 at api.easypost.com. It is built from EasyPost's documentation as read on 22 October 2026. 126 actions in 35 areas, each one in the signed service file (version 1.0.0). **Does actionlake keep my EasyPost data, and where?** actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to 5 minutes, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your EasyPost credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models. **Which AI clients can use it?** Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names. ## More connectors like EasyPost Shares the most action names with - [Shippo 12](https://actionlake.com/connectors/shippo) - [ShipHero 12](https://actionlake.com/connectors/shiphero) - [Duffel Flights & Stays 9](https://actionlake.com/connectors/duffel-flights-and-stays) - [Easyship 9](https://actionlake.com/connectors/easyship) - [ShipStation 9](https://actionlake.com/connectors/shipstation) - [Shippit 6](https://actionlake.com/connectors/shippit) Joins with, on shared entities - [Whop 3](https://actionlake.com/connectors/whop) - [ActiveCampaign 2](https://actionlake.com/connectors/activecampaign) - [Avalara AvaTax 2](https://actionlake.com/connectors/avalara-avatax) - [Guesty 2](https://actionlake.com/connectors/guesty) - [BILL 2](https://actionlake.com/connectors/bill) - [Lightspeed Retail X-Series 2](https://actionlake.com/connectors/lightspeed-retail-x-series) Browse - [All Commerce connectors](https://actionlake.com/connectors/category/commerce) - [All connectors](https://actionlake.com/connectors) - [How actionlake compares](https://actionlake.com/compare) actionlake is independent.
