# Stripe Agent 1 Progress: Account Management & Credential System

## Status: Starting Refactoring
- Started: 2025-07-12
- Agent: Stripe Refactor Agent 1
- Scope: Account management and credential system only

## Task Overview
Refactoring ONLY the account management and credential portions of mcp-stripe:
1. Extract and refactor these 7 tools with stripe_ prefix:
   - list_accounts → stripe_list_accounts
   - switch_account → stripe_switch_account  
   - add_account → stripe_add_account
   - remove_account → stripe_remove_account
   - get_active_account → stripe_get_active_account
   - set_default_account → stripe_set_default_account
   - update_account → stripe_update_account

2. Create modular structure:
   - src/services/credential-manager.ts
   - src/services/account-state.ts
   - src/tools/account/* (7 files + index.ts)
   - src/schemas/account.ts
   - src/types/account.ts

## Progress Log

### Step 1: Initial Analysis ✅
- Examined current monolithic index.ts (1,592 lines)
- Identified account management code (lines 18-448, 689-892, 1043-1169, 1474-1497)
- Identified CredentialManager class (lines 48-414)
- Identified account schemas (lines 420-447)
- Identified account types/interfaces (lines 23-42)
- Reference: mcp-hubspot structure

### Step 2: Create Directory Structure ✅
- Created modular directory structure based on mcp-hubspot pattern
- Created src/schemas, src/services, src/tools/account, src/types, src/utils

### Step 3: Extract Types and Schemas ✅
- Created src/types/account.ts with all account-related interfaces
- Created src/types/index.ts for exports
- Created src/schemas/account.ts with Zod validation schemas
- Created src/schemas/index.ts for exports

### Step 4: Extract Services ✅
- Created src/services/credential-manager.ts (extracted from lines 48-414)
- Created src/services/account-state.ts (new service for account state management)
- Created src/services/index.ts for exports

### Step 5: Create Account Management Tools ✅
- Created src/tools/account/list-accounts.ts (stripe_list_accounts)
- Created src/tools/account/switch-account.ts (stripe_switch_account)
- Created src/tools/account/add-account.ts (stripe_add_account)
- Created src/tools/account/remove-account.ts (stripe_remove_account)
- Created src/tools/account/get-active.ts (stripe_get_active_account)
- Created src/tools/account/set-default.ts (stripe_set_default_account)
- Created src/tools/account/update-account.ts (stripe_update_account)
- Created src/tools/account/index.ts with exports and handler mappings
- Created src/tools/index.ts for main tool exports

### Step 6: Integration Testing ✅
- Created test script to validate modular structure
- All 7 account tools correctly exported with stripe_ prefix
- All services can be imported and instantiated
- Schema validation working correctly
- Test results:
  - ✅ Services imported successfully
  - ✅ Imported 7 account tools
  - ✅ Imported 7 tool handlers  
  - ✅ Schema validation works
  - ✅ All tools have stripe_ prefix: true

## Summary

Successfully completed the refactoring of account management and credential system for mcp-stripe:

✅ **Extracted 7 Account Management Tools** (all with stripe_ prefix):
- stripe_list_accounts
- stripe_switch_account  
- stripe_add_account
- stripe_remove_account
- stripe_get_active_account
- stripe_set_default_account
- stripe_update_account

✅ **Created Modular Architecture**:
- src/types/account.ts - All account-related type definitions
- src/schemas/account.ts - Zod validation schemas for account operations
- src/services/credential-manager.ts - Secure credential storage service
- src/services/account-state.ts - Account state management service
- src/tools/account/* - 7 individual tool files + index.ts
- All with proper exports and handler mappings

✅ **Validated Structure**:
- All modules import/export correctly
- Tool naming follows stripe_ prefix convention
- Services are properly encapsulated
- Ready for integration with other agents' work

## Next Steps for Other Agents
1. Other agents can now work on their assigned tool categories
2. The modular structure is ready for integration
3. Use src/tools/index.ts to add new tool categories
4. Reference this work for consistent patterns
