# ChatGPT2API-Pro Hermes Integration — Session 2026-07-04

## Project State
- **Repo:** `nikita4a/chatgpt2api-pro` (fork of `lanqian528/chat2api`)
- **Local path:** `C:\Users\User\AppData\Local\hermes\chatgpt2api-pro\`
- **Port:** `:5005`
- **Token:** K12 account `[REDACTED-NAME]@gmail.com` (planType: k12, workspace)
- **PoW:** `POW_DIFFICULTY=000001` (critical fix from `999999`)

## Files Created/Modified
- `api/function_calling.py` — prompt-engineering tool use (173 lines)
- `api/mcp.py` — JSON-RPC 2.0 MCP endpoint (151 lines)  
- `api/chat2api.py` — modified pipeline with tool injection
- `app.py` — MCP endpoint registration
- `.env` — POW_DIFFICULTY=000001, SCHEDULED_REFRESH=true
- `READ.md` — documentation

## Hermes Integration Files
- `C:\Users\User\.hermes\mcp-servers\chatgpt2api_mcp_bridge.py` — stdio→HTTP MCP bridge
- `C:\Users\User\AppData\Local\hermes\config.yaml` — custom_provider `chatgpt-web` + mcp_server `chatgpt2api`

## Models Tested
- GPT-4o: ✅ (conversation_id, content)
- GPT-5.5: ✅ (thinking:true, response "4" for "2+2=?")
- O3-mini: ✅
- O1: ❌ (anti-abuse block on K12)

## POW_DIFFICULTY Debug
- `999999` → error "difficulty too high: 07a120" (hex string comparison trap)
- `000001` → works (minimal hex, only blocks '000000'/'000001')
- Root cause: `ChatService.py:255` — `proofofwork_diff <= pow_difficulty` (lexicographic)

## Port Conflict Debug
- PID 36876 held port 5005 after previous crash
- `taskkill //F //PID 36876` + `sleep 5` → resolved
- Multiple failed starts due to TIME_WAIT

## MCP Bridge Test
```bash
echo '{"jsonrpc":"2.0","method":"tools/list","id":1}' | \
  CHATGPT_TOKEN="<token>" python chatgpt2api_mcp_bridge.py
# → {"jsonrpc":"2.0","id":1,"result":{"tools":[...]}}
```

## Token Expiry Event (2026-07-04 17:00)
- Token `[REDACTED-NAME]@gmail.com` K12 revoked with `token_revoked` error
- `refresh_all_tokens` useless — only refreshes live tokens, can't recover revoked
- Browser tool blocked by Cloudflare challenge on chatgpt.com
- Comet CDP not running on :9222
- **Resolution pending**: need user to provide fresh token from live browser session

## Server Start Command
```bash
cd "C:/Users/User/AppData/Local/hermes/chatgpt2api-pro"
PYTHONPATH="C:/Users/User/AppData/Local/hermes/chatgpt2api-pro;$PYTHONPATH" \
