### Overall Assessment: β
APPROVED FOR PUBLIC RELEASE
---
## π Audit Scope
### Files Audited
- β
`index.js` - Main server implementation
- β
`package.json` - Package configuration
- β
`setup.sh` - Installation script
- β
`warp-mcp-config.json` - Configuration template
- β
`README.md` - Documentation
- β
All supporting documentation files
### Security Dimensions Reviewed
1. Personal Information (PII)
2. Hardcoded Credentials
3. File Path Security
4. Dependency Vulnerabilities
5. Code Security Patterns
6. Documentation Completeness
---
## π Detailed Findings & Remediations
### 1. Personal Information Removal β
#### **Finding:** Personal identifiers in configuration files
**Original Issues:**
- Username "bob" in file paths: `/home/bob/gemini-mcp-server/`
- Company name "CyberLink Security" in package.json
**Remediation:**
```diff
- "args": ["/home/bob/gemini-mcp-server/index.js"]
+ "args": ["${HOME}/gemini-mcp-server/index.js"]
- "author": "CyberLink Security"
+ "author": "Gemini MCP Server Contributors"
```
**Status:** β
RESOLVED
---
### 2. Dynamic Path Resolution β
#### **Finding:** Hardcoded absolute paths in setup script
**Original:**
```bash
cat warp-mcp-config.json | sed "s/PASTE_YOUR_API_KEY_HERE/$API_KEY/"
```
**Improved:**
```bash
INSTALL_DIR="$(cd "$(dirname "$0")" && pwd)"
cat "$INSTALL_DIR/warp-mcp-config.json" | sed "s|\${HOME}|$HOME|g"
```
**Benefits:**
- Works from any installation directory
- No hardcoded paths
- Portable across users and systems
**Status:** β
RESOLVED

### 6. Code Security Review β
#### **API Key Handling:**
```javascript
// β
SECURE: Environment variable only
const GEMINI_API_KEY = process.env.GEMINI_API_KEY;
if (!GEMINI_API_KEY) {
console.error("Error: GEMINI_API_KEY environment variable is required");
process.exit(1);
}
```
**Validation:** No API key is logged or exposed in error messages
#### **Error Handling:**
```javascript
// β
SECURE: Safe error messages
catch (error) {
return {
content: [
{
type: "text",
text: `Error: ${error.message}`, // Only message, not full stack
},
],
isError: true,
};
}
```
**Validation:** Errors don't leak sensitive information
#### **Input Validation:**
```javascript
// β
SECURE: JSON Schema validation
inputSchema: {
type: "object",
properties: {
message: { type: "string" },
temperature: { type: "number" },
max_tokens: { type: "number" }
},
required: ["message"]
}
```
**Validation:** All inputs validated by MCP SDK
**Status:** β
SECURE
---
### 7. File Permissions β
#### **Recommendations Implemented:**
```bash
# Setup script creates secure config
chmod 600 ~/.config/warp/mcp.json # Owner read/write only
# Executable scripts
chmod +x index.js setup.sh # Executed by user
```
**Status:** β
DOCUMENTED IN SECURITY.md
