--- title: "Resend MCP server for AI agents - actionlake" description: "Give Claude 113 Resend actions through one MCP server: contacts, automation, email, segment. Your agent never holds the credential. 100,000 calls a month free." canonical: https://actionlake.com/connectors/resend updated: 2026-10-10 --- Connectors · Email & messaging # Resend MCP server for AI agents. actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Resend and the rest of your systems. It gives your agent 113 Resend actions (52 reads, 42 writes and 19 that wait for a confirmation) and holds the Resend credential itself, so the agent never does. It paces Resend's limits and records every call. [Connect Resend 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: "resend.emails_list", intent: "check which Resend account is connected" } # List Sent Emails · read · 1 upstream call ``` - 113 actions in one signed file - 52 read look, never change - 42 write create and update - 19 wait for a yes destructive, confirmed first Set up ## Connect Resend 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 Resend. API key. 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` Resend API key (re_...) - `api_base` Where your Resend lives: your api base ``` account { op: "connections.requirements", service: "resend" } # 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: "resend.emails_list" } # list sent emails · read · 1 upstream call check { action: "resend.emails_send", input: { … } } # free: inputs, permissions, cost and confirmations, nothing sent ``` Resend at a glance **Sign-in** API key.

`resend.usage_get` Retrieve Usage read Questions ## The Resend MCP server, answered. **Is there a Resend MCP server for Claude?** Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 113 Resend actions across contacts, automation, email and segment, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Resend. **What do I need to connect Resend?** Resend API key (re_...). Plus your api base. The free call account { op: "connections.requirements", service: "resend" } lists exactly what to paste. **Can an AI agent delete or change things in Resend?** Only if its key allows it, and only with an explicit confirmation. 19 Resend actions are destructive, including cancel Email, delete Contact and remove Contact from Segment. 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 Resend API limit?** actionlake paces every call to the limits in the Resend service file: 10 calls a second per connection. Repeated reads are answered from cache (51 Resend actions can be), which never reaches Resend. **What does a Resend action cost?** One upstream call, the only unit actionlake bills. A list that pages bills one call per page (28 Resend actions page). Cache hits, searches, dry runs and calls Resend 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 Resend API does it cover?** The Resend API unversioned at api.resend.com by default, or the base URL set when you connect. It is built from Resend's documentation as read on 19 September 2026. 113 actions in 14 areas, each one in the signed service file (version 1.0.0). **Does actionlake keep my Resend data, and where?** actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to an hour, 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 Resend 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 Resend Shares the most action names with - [Twilio SendGrid 55](https://actionlake.com/connectors/twilio-sendgrid) - [Elastic Email 44](https://actionlake.com/connectors/elastic-email) - [Sinch Mailjet 43](https://actionlake.com/connectors/sinch-mailjet) - [Bird 38](https://actionlake.com/connectors/bird) - [Mailtrap 26](https://actionlake.com/connectors/mailtrap) - [SparkPost 25](https://actionlake.com/connectors/sparkpost) Joins with, on shared entities - [Circle 2](https://actionlake.com/connectors/circle) - [beehiiv 2](https://actionlake.com/connectors/beehiiv) - [HubSpot CRM 1](https://actionlake.com/connectors/hubspot-crm) - [Microsoft Dynamics 365 1](https://actionlake.com/connectors/microsoft-dynamics-365) - [Cvent 1](https://actionlake.com/connectors/cvent) - [Close 1](https://actionlake.com/connectors/close) Browse - [All Email & messaging connectors](https://actionlake.com/connectors/category/email-and-messaging) - [All connectors](https://actionlake.com/connectors) - [How actionlake compares](https://actionlake.com/compare) actionlake is independent.
