Claude is a strong partner for marketing work that takes judgment: briefs, copy, plans. What it doesn't have on its own is your numbers, so it can't tell you which channel paid off last week. OneLence fills that gap.
OneLence connects to Claude through its MCP server at https://mcp.onelence.com. Once it's connected, Claude answers growth questions with your own OneLence data: what to focus on today, which channels and partners to scale, hold or stop, how AI search engines see your site, and which search pages to improve first.
Connect OneLence to Claude
- In Claude, open Customize → Connectors, choose + Add, then Add custom connector.
- Name it OneLence, paste
https://mcp.onelence.com, choose Continue, then Add. - Sign in to OneLence, pick the workspace Claude may use and approve.
Custom connectors are available on every Claude plan: Free, with one custom connector, Pro, Max, Team and Enterprise. On Team and Enterprise, an Owner adds OneLence once under Organization settings → Connectors and each member then connects. You need a OneLence account with at least one website added. If you don't have one yet, start the 7-day free trial.
Claude connectors and MCP
A custom connector in Claude is a remote MCP server: Model Context Protocol is the open standard Claude uses to reach outside tools and data. OneLence runs its server at https://mcp.onelence.com, so adding it as a custom connector is all the setup Claude needs. The same server works in Claude Code, ChatGPT and other MCP clients. See how the OneLence MCP server works. For other MCP servers marketers add to Claude, such as HubSpot, Google Analytics and Meta Ads, see MCP servers for marketing.
What you can ask
| Ask Claude | What you get back |
|---|---|
| "What should I focus on today?" | Today's priorities and which channels and partners to scale, hold or stop, as an interactive briefing |
| "Why does OneLence say to hold Google Ads?" | The reasons, the evidence, what is still missing and when to look again |
| "How did last week compare with the week before?" | Visitors, conversions, conversion rate and revenue, each with its change |
| "Which affiliates actually convert?" | Partners, coupons, clicks and conversions side by side |
| "Where did last week's Shopify orders come from?" | Orders and revenue by source, campaign, affiliate and coupon code, once the OneLence Connect app is on your store |
| "How do AI search engines see our site?" | The assistants that read your pages, the visitors they send and the fixes to make (Premium) |
| "Which search pages should we improve first?" | Ranked Search Console opportunities, each with a next step (Premium) |
| "We doubled the TikTok budget yesterday. Log it." | A summary to confirm; once you agree, OneLence records the change and watches what follows |
Answers as interactive cards
Claude shows four OneLence answers as interactive cards rather than plain text: the daily briefing, the list of what to scale, hold or stop, the recommendation for a single source, and the performance overview. A card only lays out what OneLence returned and makes no network requests of its own.
Built to be safe
- Nothing changes without you. Recording a change or updating your business context shows a summary first and is saved only after you confirm.
- No access to ad accounts or money. OneLence never edits campaigns or budgets on ad platforms and never charges you from chat. The most it does is return a link to OneLence's own checkout page.
- One workspace, the permissions you chose. Claude sees only the workspace you picked when connecting, and secret API keys are never returned.
- Disconnect at any time. Remove Claude under Settings → Developer in OneLence and its access ends immediately.
Plans and roles
The connector works on every OneLence plan with an active subscription or trial. AI visibility, bot traffic and SEO opportunities need the Premium or Scale plan, and registering sites or changing conversion events needs an Owner or Admin role. See pricing.
Working in Claude Code?
The same server works in Claude Code, where OneLence can also add tracking to your app and check that events arrive. See OneLence for coding agents.
