# Constant Contact MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Constant Contact and the rest of your systems. It gives your agent 115 Constant Contact actions (61 reads, 39 writes and 15 that wait for a confirmation) and holds the Constant Contact credential itself, so the agent never does. It paces Constant Contact's limits and records every call. Connecting Constant Contact needs your own Constant Contact OAuth app and one admin sign-in.

[Connect Constant Contact 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`

```

- 115 actions in one signed file
- 61 read look, never change
- 39 write create and update
- 15 wait for a yes destructive, confirmed first

Set up

## Connect Constant Contact 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 Constant Contact.
   OAuth 2.0, authorization code with PKCE. You register your own OAuth app with Constant Contact, an admin signs in once, and you paste the app's client id and secret and the tokens from that sign-in; actionlake renews the access token from then on. actionlake stores what you paste write-only, sealed under your tenant's key.
   Before the first sign-in, Constant Contact needs an OAuth app of your own, registered in its developer portal. actionlake has no Constant Contact app to lend you.
   - `access_token` Access token from one sign-in with your own OAuth app
   - `refresh_token` Refresh token from the same sign-in; the access token is renewed from it
   - `client_id` Constant Contact app API key (client id)
   - `client_secret` Constant Contact app secret
   ```
   account { op: "connections.requirements", service: "constant_contact" }
   # 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: "constant_contact.account.get" }
   # get account summary · read · 1 upstream call
   check { action: "constant_contact.events.create", input: { … } }
   # free: inputs, permissions, cost and confirmations, nothing sent
   ```

Across your systems

## Constant Contact, joined to the rest of your business.

One `ask` fetches from Constant Contact and another system, joins the rows on the same customer on our side, and hands your agent the answer, not every row.

- Which contacts are in both Constant Contact and HaloPSA, and how many are in only one of them?
  `constant_contact.contacts.list` + `halopsa.users.list`, on `crm.contact` · [HaloPSA](https://actionlake.com/connectors/halopsa)
- Which contacts are in both Constant Contact and NetSuite, and how many are in only one of them?
  `constant_contact.contacts.list` + `netsuite.views.contacts`, on `crm.contact` · [NetSuite](https://actionlake.com/connectors/netsuite)

Also mapped by other connectors `crm.contact` **192** `comm.event` **47** `crm.tag` **47** `crm.contact_list` **22**

ask

```
ask {
  intent: "which contacts are in both Constant Contact and HaloPSA, and how many are in only one of them",
  steps: [
    { action: "constant_contact.contacts.list", as: "people", input: {}, limit: 100, max_pages: 5 },
    { action: "halopsa.users.list", as: "people2", input: {}, limit: 100, max_pages: 5 },
    { join: {
        left: "people",
        right: "people2",
        on: "crm.contact",
        group_by: "people.email",
        select: ["people.email", "count(people2.id) as in_halopsa"]
    } }
  ]
}
```

Example. Run it through check first: it validates the steps and prices them, and it is free.

Governance for Constant Contact

## Destructive actions wait for a yes.

15 Constant Contact actions are destructive. These are all of them:

- Delete a contact `constant_contact.contacts.delete`
- Delete a tag `constant_contact.contact_tags.delete`
- Delete a contact list `constant_contact.contact_lists.delete`
- Delete contacts in bulk `constant_contact.contacts.bulk_delete`
- Delete an email campaign `constant_contact.email_campaigns.delete`
- Delete tags in bulk `constant_contact.contact_tags.bulk_delete`
- Delete a segment `constant_contact.segments.delete`
- Delete contact lists in bulk `constant_contact.contact_lists.bulk_delete`
- Delete a resend to non-openers `constant_contact.non_opener_resends.delete`
- Unschedule an email campaign activity `constant_contact.campaign_activity_schedules.delete`
- Delete a custom field `constant_contact.custom_fields.delete`

- Delete custom fields in bulk `constant_contact.custom_fields.bulk_delete`
- Remove tags from contacts `constant_contact.taggings.bulk_remove`

A destructive action runs only with `confirm: true`. Under the `human` policy the agent cannot confirm for itself: the run stops until a named person approves, in the console or from a signed link in an email. The cap on a key is refused before the call is sent, never after.

Questions

## The Constant Contact MCP server, answered.

**Is there a Constant Contact MCP server for Claude?**

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 115 Constant Contact actions across contacts, reports, campaigns and bulk, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Constant Contact.

**What do I need to connect Constant Contact?**

Your own Constant Contact OAuth app, registered with Constant Contact (its client id and client secret), and the access and refresh tokens from one admin sign-in. actionlake has no Constant Contact app of its own, so this is not a one-step consent. actionlake renews the access token as it expires. The free call account { op: "connections.requirements", service: "constant_contact" } lists exactly what to paste.

**Can an AI agent delete or change things in Constant Contact?**

Only if its key allows it, and only with an explicit confirmation. 15 Constant Contact actions are destructive, including delete a contact, delete a tag and delete a contact list. 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 Constant Contact API limit?**

actionlake paces every call to the limits in the Constant Contact service file: 4 calls a second and 10,000 a day per connection. Repeated reads are answered from cache (61 Constant Contact actions can be), which never reaches Constant Contact.

**What does a Constant Contact action cost?**

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (28 Constant Contact actions page). Cache hits, searches, dry runs and calls Constant Contact 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 Constant Contact API does it cover?**

The Constant Contact V3 API API v3 at api.cc.email/v3. It is built from Constant Contact's documentation as read on 20 September 2026. 115 actions in 8 areas, each one in the signed service file (version 1.0.0).

**Can I combine Constant Contact with my other systems?**

Yes. ask joins Constant Contact to HaloPSA or NetSuite on the same customer and returns the answer rather than every row. Constant Contact maps crm.contact, which 192 other connectors also map.

**Does actionlake keep my Constant Contact 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 Constant Contact 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.
