Claude Code with Markup AI MCP
Coding
Overview
Connect Claude Code to the hosted Markup AI MCP server at https://api.markup.ai/mcp/. Add the remote server and authenticate with either an interactive login or an API key.
You’ll need a Markup AI account to continue. Sign up at https://console.markup.ai/signup.
Add the Markup AI MCP Server to Claude Code
Log in with OAuth
Use an API key
Get your API key
- Visit https://console.markup.ai/signup and create an account.
- Copy your API key from the console.
Store your key securely. Prefer environment variables or a secrets manager over committing keys to code.
Use either OAuth or an API-key header—not both. If you set an Authorization header and the server rejects it, Claude Code reports a failure rather than falling back to OAuth.
Manage Your MCP Servers (Claude CLI)
Use the Claude CLI to manage configured servers:
Test Your Setup
- “Check this announcement for brand-voice drift: [paste text]”
- “Flag any hard-to-read sentences in this doc and rewrite them: [paste text]”
- “List the available Markup AI agents.”
Troubleshooting
- Confirm the server URL is
https://api.markup.ai/mcp/. - If using an API key, ensure it’s sent as
Authorization: Bearer YOUR_API_KEYwith no extra spaces or quotes. - Some clients require a full restart to load new MCP servers.
