How to Install the MKT1 MCP
Install the MCP server in Claude through your desktop or web app and it will work in Claude Chat, Cowork, or Code. The whole thing takes about 2 minutes.
Open Claude and click Customize in the left sidebar, then click Connectors. Hit the + button at the top and select Add custom connector.
Fill in the 2 fields and click Add:
Name: MKT1
MCP server URL:
https://mcp.mkt1.co/mcp
Note: This URL goes nowhere when put into a browser, you must put this in the input in Claude Customize!
The MKT1 MCP Server now shows up in your connectors list under “Not connected.”
Click on it, then click Connect. This will open a new window where you enter your MKT1 Newsletter subscription email (your Substack login email).
Give it a moment to verify; if it seems to stall, just try again.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 be able to search our newsletter archive and job board only. Upgrade to unlock full access ➜
[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.
