emojikey-server MCP Server
About
This server implements the Model Context Protocol for persisting LLM interaction styles as emoji-based context keys (“emojikeys”). It allows large language models to maintain consistent interaction styles across conversations by storing emojikeys online, so they can be used…

- Get the current emojikey for a user/model combination
- Set new emojikeys during conversations
- Retrieve emojikey history across sessions
- Automatic API key generation and validation
- Emojikeys stored online for cross-device consistency

}MCP Protocol for persisting LLM interaction style as emojikeys
This server allows LLMs to maintain consistent interaction styles across conversations using emoji-based context keys ("emojikeys").
Emojikeys are stored online, so you can use them accross devices and applications. No user information is stored other than the emojikeys.
If there is interest in a local-only version, or other suggestions, please reach out and let me know. Actively developing this concept now.
> 📝 Note
> Usage note: The first time you use the tool in Claude desktop, tell Claude to "Set emojikey" then next time you start a conversation, he will automatically use this key. You can ask to set vibe, or show emojikey history as well. Have fun!
> ⚠️ Warning
> This is a beta version, more features are planned, so the API may change.

Development
Install dependencies:
npm install
Build the server:
npm run build
For development with auto-rebuild:
npm run watch
Test the server:
npm run test
Environment Variables
- EMOJIKEYIO_API_KEY - Your emojikey.io API key
- MODEL_ID - Identifier for the LLM model (e.g., "Claude-3-5-Sonnet-20241022")
Debugging
Since MCP servers communicate over stdio, debugging can be challenging. We recommend:
1. Using the test script: npm run test
2. Using the MCP Inspector:
npm run inspector
