Who it is for
Growth and lifecycle teams that send across several channels from OneSignal.
OneSignal
Messaging, segment, and analytics access for OneSignal
Overview
What OneSignal does
OneSignal is a customer engagement platform, and its MCP server opens an account to an AI agent. The readable objects include users, segments, sent messages, templates, and analytics, which is enough to answer questions about the product setup as well as questions about how a given campaign performed.
The tools go past reporting. An agent can work through delivery and engagement problems, draw conclusions from the figures it reads, and help put together personalized messaging across the channels the platform lists: email, push, SMS, RCS, Live Activities, and in-app messages.
What stands out
A single connection covers both the analytical side and message creation across every channel the platform names.

Where OneSignal is listed
OneSignal ships this on both marketplaces: OneSignal is listed in the Claude connectors directory and in the ChatGPT apps directory, under the same publisher domain.
Only 392 of the 3,150 products in this directory are listed in both marketplaces. One MCP server can serve both surfaces; what differs is each platform's listing and review process.

Claude listing
In the Claude connectors directory
OneSignal publishes 29 tools to Claude, deeper than 80.3% of the 1,253 Claude-listed connectors.
The median Claude-listed connector filed under Communication publishes 11, so this one runs 18 tools above its bucket's median and ranks 9th of 29 by tool count.
It falls in the 21-50 tools band, which holds 20% of the Claude directory.
OneSignal publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.
Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.

OneSignal carries partner verification in the Claude directory, which 474 of 1,253 listings do (37.8%). That is a review step past self-publishing, not an Anthropic-built server.
In the publisher's words
How OneSignal describes it
The OneSignal MCP server gives AI agents direct access to OneSignal’s customer engagement platform. Agents can explore users, segments, messages, templates, and analytics; answer product and campaign questions; troubleshoot delivery and engagement issues; generate insights; and help create personalized omnichannel messaging across push, email, SMS, RCS, in-app messaging, and Live Activities.
