Full read-write Claude connector for Marketo
Make Claude build programs and manage leads in Marketo
Stop clicking through the Marketo UI to update leads, stage segments, and edit programs. Claude works the data and campaign setup where it already lives, and a smart campaign only runs once you approve it.
Marketo is Adobe's marketing automation platform for lead management, email campaigns, and nurture programs. People want Claude to do more than read campaign stats: to build and update programs, manage leads and lists, and trigger sends from inside the platform.
What is a Marketo MCP server?
A Marketo MCP server is a small hosted service that exposes Marketo's data and actions to Claude over the Model Context Protocol, so Claude can campaigns, lists, and audiences inside your own account. We build it as a custom connector with separate read and write tools, and destructive actions stay gated behind your approval.
What can Marketo's current connector do today?
Adobe does offer an official Marketo MCP server, but it ships a fixed, standard tool set that covers a generic slice of the platform and is not shaped to how your team runs programs. A custom connector adds the actions, custom fields, list and program workflows, scoping, and human-in-the-loop controls that the native tool set leaves out, so the campaign work happens where the data already lives.
What does full read-write Marketo access unlock?
Full read-write Marketo access lets Claude create and update lead records, add or remove members from static lists, build and edit email programs, and request a smart campaign run once you approve. The campaign setup and lead hygiene that used to mean clicking through the UI happen where the data already lives.
- Create or update lead records and their field values from a brief
- Add or remove leads from a static list to stage a segment
- Build or edit an email program and its assets
- Clone and rename a smart campaign before a launch
- Activate a smart campaign and request a run after you approve it
- Pull program performance and propose follow-up nurture steps
Can Claude create and update leads in Marketo?
Yes. Creating and updating leads in Marketo is a write action a custom connector exposes through the REST API, so Claude can build new lead records and update their field values from a brief. Directory-style options are usually read-leaning, which is why these writes need a purpose-built connector with scoped permissions.
Can Claude build and edit an email program in Marketo?
Building and editing an email program in Marketo is supported through the connector's write tools. Claude can create or edit a program and its assets, clone and rename a smart campaign before launch, and stage segments by adding or removing leads from a static list, all under the connected identity's permissions.
Will Claude launch a Marketo smart campaign without my approval?
No. Requesting a smart campaign run in Marketo is a separate, gated write action. Claude can stage the segment, clone and rename the campaign, and activate it in advance, but the campaign only runs after you confirm it. You decide which actions happen freely and which wait for a human before anything reaches leads.
How a Marketo connector works
We build a small MCP server that authenticates to Marketo's REST API with a scoped service identity and the narrowest permissions the work needs. Read tools (query leads, read programs) and write tools (update leads, edit programs, manage lists) are separated, and outbound or destructive actions like requesting a campaign run require your confirmation. Claude only ever has the access the connected Marketo identity already has.
