How to install the MKT1 MCP
01
One-click Install: Click here to go directly to Claude and add MKT1 MCP as a custom connector. This is the easiest path!
02
If that didn't work, add it by hand. In Claude, go to Customize, then Connectors, hit the + button at the top and select Add custom connector. Name: MKT1. MCP server URL: https://mcp.mkt1.co/mcp. Note: this URL goes nowhere in a browser, you have to paste it into the input in Claude Customize.
03
The MKT1 MCP Server now shows up in your connectors list under “Not connected.” Click on it, then click Connect. This opens a new window.
04
In the new window, enter your MKT1 Newsletter subscription email (your Substack login email). Give it a moment to verify; if it stalls, just try again.
05
If you’re a paid subscriber, you’ll see all available tools & everything we ship in the future. If you’re not a paid subscriber, you’ll get newsletter search, job board search, the skills list, the changelog, help, and a handful of free skills. Upgrade to unlock full access ➜
06
[Optional] Once connected, click on the MKT1 MCP Server in your connectors list and find the Tool permissions dropdown that says “Custom.” Switch it to Always allow. That way Claude can use MKT1 skills without asking your permission every time, which gets old fast.

How do I use an MKT1 MCP skill in Claude?
Ask Claude "What skills does MKT1 MCP Server have?" Or if you know the skill already, just ask to use it by name, referencing the MKT1 MCP. Examples: "Using the MKT1 MCP, run MKT1 channel strategy on [your URL]" or "Help me build my marketing strategy with the MKT1 MCP."
How do I share MKT1 skills with my team?
Everyone on your team can connect their own Claude account to the MKT1 MCP Server. If you want to save company-specific additions to skills, you'll need to share those with your team using a GitHub repo, shared folders, Claude Chat projects, etc.
Why is the MKT1 MCP showing me as a free subscriber when I'm a paid MKT1 Newsletter subscriber?
Most common cause: The email you signed in with doesn't match your Substack subscription email exactly. Disconnect the MKT1 MCP Server in Claude → Customize → Connectors, reconnect, and sign in carefully. If you just upgraded, wait 2-3 minutes then reconnect. Your access tier is set when you connect.
Why don't I see MKT1 tools after connecting to the MKT1 MCP Server?
Go to Claude → Customize → Connectors → MKT1 MCP Server. Set Tool permissions to "Always allow" so Claude pulls in MKT1 tools automatically. If you still don't see them, disconnect and reconnect the connector to force a fresh load.
How do I get support for the MKT1 MCP Server?
Ask Claude for help directly through the MKT1 MCP. There's a built-in help tool for troubleshooting. Just say "MKT1 MCP help: [your issue]." For anything that needs a human, submit through our support form: https://mcp.mkt1.co/help. We can't respond to support requests via Substack comments or DMs.
How many Claude credits does the MKT1 MCP Server use?
Most skills run as a normal conversation, so minimal credits. Agentic, multi-step tasks (research, automations) use more. I'm on the Claude Max plan and have only hit the limit once.
What is a marketing MCP?
An MCP (Model Context Protocol) server connects an AI assistant like Claude to outside tools and content. A marketing MCP connects Claude to marketing tools, data, or expertise. Most marketing MCPs connect a single tool, like your CRM or ad platform. The MKT1 MCP is different: it connects Claude to marketing expertise, with 40+ skills, the MKT1 Newsletter archive, and MKT1 frameworks.
How does the MKT1 MCP compare to other marketing MCPs?
Most marketing MCPs connect Claude to a tool you already use: your CRM, your ad platform, your analytics. The MKT1 MCP connects Claude to marketing strategy instead: exercises, frameworks, and content from MKT1. They work well together. Use tool MCPs for your data, and the MKT1 MCP for strategy and execution.
