## 1. Public Release Readiness Assessment
### 1.1 Threat Model
| Threat Category | Current State | Risk Level | Mitigation Status |
|-----------------|---------------|------------|-------------------|
| **API Key in Chat** | OAuth Device Flow prevents keys in conversation | ✅ Low | `session.ts:254-416` - browser-based auth |
| **Credential Storage** | AES-256-GCM encrypted at `~/.baremcp/credentials.json` | ✅ Low | `session.ts:50-96` |
| **Command Injection** | `spawn()` with array args, no `exec()` | ✅ Low | `session.ts:165-204` |
| **SSRF (Webhooks)** | HTTPS-only, blocks localhost/private IPs | ✅ Low | `webhooks.ts:52-101` |
| **Information Disclosure** | Error sanitization blocks sensitive patterns | ✅ Low | `errors.ts:223-248` |
| **Prompt Injection** | No user input passed to system prompts | ✅ Low | Tool handlers validate/sanitize |
| **DoS (Media Upload)** | 64MB base64 limit | ⚠️ Medium | `media.ts:43` - consider lowering |
| **Multi-tenant Isolation** | Session-scoped auth, no cross-tenant access | ✅ Low | Store-scoped API paths |
| **Data Exfiltration** | API key scoping limits exposure | ✅ Low | Role-based permissions |
**Critical Gaps:**
1. No rate limiting on MCP tool calls (API-side handles this)
2. No audit of stored credentials file integrity
3. Missing telemetry opt-out mechanism documentation
### 1.2 Dependency/License Scan
| Package | Version | License | Risk |
|---------|---------|---------|------|
| `@modelcontextprotocol/sdk` | ^1.0.0 | MIT | ✅ None |
| `zod` | ^3.23.8 | MIT | ✅ None |
| `typescript` | ^5.4.0 | Apache-2.0 | ✅ None |
| `bun-types` | latest | MIT | ✅ None |
| `eslint` | ^8.57.0 | MIT | ✅ None |
| `prettier` | ^3.2.0 | MIT | ✅ None |
**License Assessment:** All dependencies are MIT/Apache-2.0 compatible. No copyleft, no commercial restrictions.
**Security Advisory Check Required:**
- Run `bun audit` or `npm audit` before release
- Pin `@modelcontextprotocol/sdk` to specific version
### 1.3 Operational Risks
| Risk | Current State | Severity | Recommendation |
|------|---------------|----------|----------------|
| **No request timeout** | Relies on API timeouts | Medium | Add 30s timeout to fetch calls |
| **No retry logic** | Single attempt per request | Medium | Implement exponential backoff |
| **PII in logs** | `console.error` for debug | Medium | Redact credentials from logs |
| **Telemetry** | None implemented | Low | Document no-telemetry policy |
| **Credential file permissions** | 0600 set correctly | Low | Verified in `session.ts:107` |
### 1.4 UX Risks
| Risk | Impact | Resolution |
|------|--------|------------|
| **Authoritative context requirement** | Server fails if `contract-objectives.md` missing | Document as optional or remove requirement for public |
| **Error messages reference internal files** | Confusing for end users | Sanitize error paths |
| **No connection test on install** | Users don't know if setup worked | Add `baremcp --version` and `baremcp --test` |
| **Env var confusion** | BARECOMMERCE_* namespace unclear | Document clearly |

## 2. Exhaustive Public Release Plan
### Phase 1: Pre-Release Security Hardening ✅ COMPLETE
**Status:** Completed 2025-12-15
**Goal:** Eliminate all security risks for public deployment.
**Tasks:**
1. ✅ Remove authoritative context requirement for public mode

"command": "baremcp"
}
}
}
```
### Connect
Say to Claude: "Connect to my BareCommerce store"
(Opens browser for secure login)

|----------|----------|---------|-------------|
| `BARECOMMERCE_API_URL` | No | `https://api.barecommercecore.com` | API endpoint |
| `BARECOMMERCE_API_KEY` | No | - | Pre-configured key (skips OAuth) |
| `BARECOMMERCE_DEFAULT_STORE_ID` | No | - | Auto-select store |
## Troubleshooting
