# Datai FastMCP TypeScript Server - CONSTANTS FIX RESTART
## 🚨 CRITICAL ISSUE: Constants Configuration Broken After Phase 7
**Current Location**: `/Users/ilessio/dev-agents/PARTNERS/DATAI/datai-mcp/`
## 🔥 PROBLEM IDENTIFIED
**BEFORE Phase 7**: All 8 tools working perfectly ✅
**AFTER Phase 7**: Tools failing with validation errors ❌
**ROOT CAUSE**: Our changes to `src/config/constants.ts` broke the API configuration and environment variable loading.
## 🎯 IMMEDIATE FIX STRATEGY
### Step 1: Fix Constants.ts Configuration 🚨
**ISSUE**: The new environment variable validation in constants.ts is too strict and breaking the API client initialization.
**CURRENT BROKEN STATE**:
```typescript
// This is failing:
API_KEY: getRequiredEnvVar('DATAI_API_KEY'), // 🚨 REQUIRED - No fallback
```
**SOLUTION**: Restore working configuration with proper fallbacks for development.
### Step 2: Test Single Tool First 🎯
**TARGET**: `get-all-user-defi-positions.ts`
**APPROACH**: Fix constants → Test one tool → Verify working → Move to others
### Step 3: Identify What Actually Broke 🔍
**BEFORE (Working)**:
- Had hardcoded API key as fallback
- Simple environment loading
- All tools working
**AFTER (Broken)**:
- Removed hardcoded API key
- Complex environment validation
- Tools failing with "unrecognized_keys: metadata" and other errors
## 🔧 IMMEDIATE ACTION PLAN
### Task 1: Restore Working Constants Configuration
1. **Simplify constants.ts**:
- Remove complex environment validation
- Add back working API key configuration
- Keep simple .env loading
2. **Test API client**:
- Verify API_CONFIG is properly initialized
- Check that client can make requests
- Confirm authentication works
### Task 2: Test Single Tool
1. **Focus on**: `get-all-user-defi-positions.ts`
2. **Remove metadata temporarily** (already done)
3. **Test with simple wallet address**
4. **Verify response structure**
### Task 3: Debug Step by Step
1. **Check environment variables loading**
2. **Verify API client initialization**
3. **Test API endpoint directly**
4. **Check tool response format**
## 🚨 CRITICAL FIXES NEEDED
### Fix 1: Constants.ts API Configuration
```typescript
// WORKING VERSION (restore this approach):
export const API_CONFIG = {
BASE_URL: process.env.DATAI_BASE_URL || "https://api-v1.mymerlin.io",
API_KEY: process.env.DATAI_API_KEY || "dbNb54fQUGCuy2xO3RXPRw7bH9nbDSkS", // Fallback for dev
TIMEOUT: parseInt(process.env.DATAI_TIMEOUT || "180000"),
LIMIT: parseInt(process.env.DATAI_LIMIT || "1"),
DEBUG_TRUNCATE: process.env.DATAI_DEBUG_TRUNCATE === "true",
} as const;
```
### Fix 2: Simplify Environment Loading
```typescript
// SIMPLE VERSION (restore this):
// Just load .env if it exists, no complex validation
if (existsSync(".env")) {
// Simple .env loading without complex logic
}
```
### Fix 3: Remove Strict Validation
```typescript
// REMOVE THIS (causing issues):
function getRequiredEnvVar(name: string): string {
const value = process.env[name];
if (!value) {
throw new Error(`❌ MISSING REQUIRED...`); // This is breaking everything
}
return value;
}
```
## 🎯 SUCCESS CRITERIA
### Immediate Success (Next 10 minutes):
- [ ] Constants.ts simplified and working
- [ ] API client can initialize without errors
- [ ] Environment variables loading properly
- [ ] `get-all-user-defi-positions.ts` tool responds without validation errors
### Short Term Success (Next 30 minutes):
- [ ] All 8 tools working again
- [ ] Server starts without errors
- [ ] Tools return proper responses
- [ ] Back to Phase 6 working state
## 🔄 RESTART APPROACH
### 1. Memory Clean Slate
- Focus only on fixing constants.ts
- Ignore NPX preparation for now
- Get back to working state first
### 2. Minimal Changes
- Restore working API configuration
- Keep simple environment loading
- Remove complex validation that's breaking things
### 3. Test Driven
- Fix constants → Test API client → Test one tool → Verify all tools
## 📋 DEBUGGING CHECKLIST
### Environment Check:
- [ ] `.env` file exists and loads properly
- [ ] `DATAI_API_KEY` is available
- [ ] `API_CONFIG` object initializes without errors
- [ ] No environment validation errors on startup
### API Client Check:
- [ ] DataiClient initializes properly
- [ ] Can make test API request
- [ ] Authentication works
- [ ] Endpoints resolve correctly
### Tool Check:
- [ ] `get-all-user-defi-positions.ts` executes without errors
- [ ] Returns proper response format
- [ ] No validation errors
- [ ] Response structure matches expected format
## 🚀 IMMEDIATE NEXT STEPS
1. **Fix constants.ts** - Restore simple, working configuration
2. **Test API client** - Verify it can initialize and make requests
3. **Test single tool** - Focus on `get-all-user-defi-positions.ts`
4. **Verify response** - Check that tool returns proper format
5. **Test all tools** - Once one works, verify others
## 📞 CONTINUATION PROMPT
```
CONSTANTS FIX RESTART
CRITICAL ISSUE: Phase 7 changes to constants.ts broke all tools
GOAL: Restore working state by fixing constants configuration
APPROACH: Simplify → Test → Verify → Restore all tools
IMMEDIATE TASK: Fix src/config/constants.ts to restore working API configuration
Ready to fix the constants and get tools working again!
