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.
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.

Set up
Connect Constant Contact in three steps.
- 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.

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.

Top actions
The Constant Contact API, shaped for agents.
The ids your agent types, what each does, and the one name it shares with other systems. 72 of Constant Contact's 72 action names are shared with at least one other connector, so an agent learns them once.

Ready-made plans for Constant Contact.
8 plans in the store. Install one and your agent runs it by name; the reply says which connections are still missing. A schedule can run a plan on a timetable. There are no triggers or webhooks, by design.

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.
