emojikey-server MCP Server

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.

{
  "mcpServers": {
    "mcp-server-emojikey": {
      "command": "npx",

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
