How to connect your 📝MythOS knowledge library to 📝Claude Code using an API key.

When you connect MythOS to Claude Code, your knowledge library loads into every terminal session — search, read, create, and update memos without leaving the CLI. For an automated setup script with additional features, see the 📝MythOS Claude Code Skill.

What You'll Need

• A MythOS account with a Scholar or Oracle plan
• Claude Code installed (claude.ai/code)

Steps

1. Generate — an API key at mythos.one/settings/api-keys. Copy the key — it starts with mtk_
1. Run — the following command in your terminal, replacing the placeholders with your key and username:

claude mcp add mythos \
  --scope user \
  https://mythos.one/api/mcp \
  --header "Accept: application/json, text/event-stream" \
  --header "x-mythos-key: YOUR_API_KEY" \
  --header "x-mythos-username: YOUR_USERNAME"

1. Restart — Claude Code for the 📝MCP connection to take effect
1. Verify — by asking Claude to search your MythOS library. If it returns results, you're connected
