Userport MCP¶

The support inbox and outbound engine, operated from a conversation. Userport is a customer support and outbound messaging platform for SaaS founders, with a remote MCP server at https://mcp.userport.io/mcp. An agent connected to it sees who is waiting, reads threads, drafts and sends answers, closes what is done, writes onboarding and outbound sequences, and reports where users drop off. Streamable HTTP with OAuth 2.1: sign in with a Userport account, no API key, and it works on every plan including the free one.

Server type: Remote (Streamable HTTP)
Auth: OAuth 2.1 (browser sign-in, no API key)
Endpoint: https://mcp.userport.io/mcp
Tools: inbox, threads, replies, sequences, analytics
Pricing: all plans including free (userport.io/pricing)
Category: Business Operations / Support
Built by: Userport (userport.io)

Why This Matters for Operators¶

Support backlogs and onboarding gaps are the same disease: conversations that need an answer, and sequences that need writing, both starved for attention. Userport turns both into outcomes the agent can deliver: list who is still waiting oldest first, summarize unread threads and draft answers, close what is answered, and then write the three-email sequence for people who never installed the widget, with a test send before it goes live.

The compound questions are where the platform earns its keep: which onboarding step loses the most people, and how did outbound do this month versus last, answered from the same connected data.

Tools & Capabilities¶

Tool group	Purpose
Inbox triage	List waiting conversations, summarize and draft answers
Replies	Send answers and close resolved threads
Sequences	Write onboarding and outbound sequences with test sends
Analytics	Drop-off analysis by step, month-over-month outbound reports
Connection control	Per-account sign-in with revocable connections

Installation¶

claude mcp add --transport http userport https://mcp.userport.io/mcp

Then run /mcp and sign in. Claude desktop and claude.ai users add the URL under Settings > Connectors > Add custom connector.

Configuration¶

{
  "mcpServers": {
    "userport": {
      "type": "http",
      "url": "https://mcp.userport.io/mcp"
    }
  }
}

The client registers itself, the operator signs in and chooses what to allow, and connections can be revoked in Settings > Connect.

Business Relevance¶

SaaS founders clear support backlogs and onboarding gaps in one surface
Support teams triage by outcome, not by clicking threads
Growth operators find the onboarding step losing the most users
Small teams get the whole motion on the free plan

Integration with CorpusIQ¶

Userport pairs with CorpusIQ's email connectors: Gmail handles the founder's inbox while Userport handles customer conversations, and CorpusIQ can recap support volume alongside GA4 sessions to connect activation and support load. Onboarding drop-off data from Userport joins CorpusIQ's PostHog funnels to confirm where activation actually breaks.

Limitations¶

Built for SaaS support and outbound; not a general helpdesk
Hosted by the vendor; no self-hosted option published
Sequence performance depends on list and offer quality
New listing with a short public track record
