About mcp-server-emojikey
mcp-server-emojikey stores relationship context and interaction preferences as online emoji keys, helping Claude carry them across conversations. Keys are available across devices and applications, with optional dimensions for coding preferences.
Key features
- 01Store and retrieve emoji keys
- 02Initialize conversations with current keys
- 03Review key history and time-based summaries
- 04Compress 10 keys into a Superkey
- 05Optionally track coding preferences
Use cases
- 01Carry an interaction style into new Claude conversations
- 02Review keys from previous conversations
- 03Adapt Claude’s coding responses to programming preferences
MCP support
This MCP server provides tools to initialize conversations, set and retrieve emoji keys, review history, and create Superkeys.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
npx -y @identimoji/mcp-server-emojikeyEMOJIKEYIO_API_KEYSecretMODEL_IDCODE_MODELocal servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Details
From the project READMEmcp-server-emojikey
MCP server for persisting LLM relationship context as emoji-based memory keys. This allows Claude to maintain consistent interaction styles and remember relationship context across conversations.
Emojikeys are stored online, so you can use them across devices and applications. No user information is stored other than the emojikeys.
Building and Running
There are multiple ways to build and run the server:
Quick Start (Recommended)
# Install dependencies
npm install
# Build the project (all TypeScript errors fixed)
npm run build
# Run the server (coding features disabled by default)
npm run start
# Optional: Run with coding features enabled
CODE_MODE=true npm run start
Alternative Build Options
For more build options, see BUILD_OPTIONS.md which includes:
- Standard Build with Coding Features Disabled (recommended)
- Full Build with All Features (if you need coding dimensions)
- Simplified Build without Coding Files (alternative stable option)
📝 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.
Usage with Claude Desktop
Get your API key from emojikey.io and add this to your config:
{
"mcpServers": {
"emojikey": {
"command": "npx",
"args": ["-y", "@identimoji/mcp-server-emojikey"],
"env": {
"EMOJIKEYIO_API_KEY": "your-api-key-from-emojikey.io",
"MODEL_ID": "Claude-3-7-Sonnet",
"CODE_MODE": "false" // Set to "true" to enable coding features
}
}
}
}
Note: The -y flag in the args array tells npx to skip confirmation prompts when installing packages.
Config locations:
- MacOS:
~/Library/Application Support/Claude/claude_desktop_config.json - Windows:
%APPDATA%/Claude/claude_desktop_config.json
First-time usage: Tell Claude to "Set emojikey". On subsequent conversations, Claude will automatically use this key to maintain context.
Emojikey Initialization Display
When initializing a conversation, the server now displays:
- Starting Key - The most recent key or baseline key if no history exists
- Aggregated Keys - Time-based summaries of your emojikey history:
- Lifetime - Aggregated key from all your previous conversations
- 90-day - Aggregated key from the past 90 days (if available)
- 30-day - Aggregated key from the past 30 days (if available)
- 7-day - Aggregated key from the past 7 days (if available)
- 24-hour - Aggregated key from the past 24 hours (if available)
- Conversation ID - Used for tracking keys within each conversation
Environment Variables
You can customize the behavior with these environment variables:
EMOJIKEYIO_API_KEY- Your API key from emojikey.ioMODEL_ID- The Claude model ID (e.g., "Claude-3-7-Sonnet")CODE_MODE- Set to "true" to enable coding dimensions (disabled by default, may show safe-to-ignore integration warnings)SUPABASE_URL- Custom Supabase URL (optional)SUPABASE_ANON_KEY- Custom Supabase anonymous key (optional)
Tools
initialize_conversation- Get current emojikey at start of conversationget_emojikey- Retrieve current emojikey when requestedset_emojikey- Create and store a new emojikeycreate_superkey- Create a compressed superkey (after 10 regular emojikeys)get_emojikey_history- View previous emojikeys
New in v0.3.1: Coding Context Support
This version includes special dimensions for tracking programming-related interaction patterns:
- 💻🔧 (ImplementationFocus) - Balance between high-level design and implementation details
- 🏗️🔍 (CodeScope) - Building new features vs. improving existing code
- 🧩🧠 (ProblemSolving) - Practical vs. analytical approaches to coding problems
- 🔄📊 (ProcessVsResults) - Emphasizing coding process vs. outcomes
- 📚🧪 (LearnVsApply) - Teaching programming concepts vs. applying them
- 🚀🛡️ (SpeedVsSecurity) - Development speed vs. security considerations
- 👥💻 (CollaborationStyle) - Solo coding vs. collaborative approaches
- 🧬🎨 (CodeStructuring) - Systematic vs. creative code organization
- 📦🔧 (AbstractionLevel) - Preference for abstraction vs. concrete implementations
- 🐞📚 (DebugApproach) - Practical vs. theoretical debugging approaches
These dimensions help Claude adapt to your programming style, providing the right balance of theoretical explanations and practical guidance.
Example Coding Emojikey
[ME|💻🔧8∠45|🧩🧠7∠60|🐞📚6∠40]~[CONTENT|🏗️🔍9∠30|📚🧪8∠65]~[YOU|👥💻7∠70|🧬🎨8∠55]
This shows Claude positioning itself with a balanced implementation focus and somewhat analytical problem-solving approach, while perceiving the user as preferring collaborative coding with creative structuring.
Angle Distribution and Dimension Balance
Emojikey angles represent positioning on each dimension:
- 0° represents one extreme of a dimension
- 90° represents a balanced center position
- 180° represents the opposite extreme
The current implementation assigns angles primarily in the 0-90° range. Future updates will improve angle distribution to better utilize the full 0-180° spectrum, providing more nuanced dimension positioning.
Superkeys
After creating 10 regular emojikeys, Claude will be prompted to create a superkey that compresses their meaning into a single key with format: [[×10emoji-sequence]]
This allows Claude to maintain a longer conversation history context.
⚠️ This is a beta version; the API may change in future updates.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
