+
+## Installation
+
+### Prerequisites
+
+- Python 3.8+
+- pip
+
+### Install Dependencies
+
+```bash
+cd mcp_server
+pip install -r requirements.txt
+```
+
+## Usage
+
+### Running the Server
+
+The MCP server runs via stdio:
+
+```bash
+python server.py
+```
+
+### Configuration for Claude Desktop
+
+Add to your Claude Desktop configuration:
+
+**macOS:** `~/Library/Application Support/Claude/claude_desktop_config.json`

+```json
+{
+  "mcpServers": {
+    "webhackersweapons": {
+      "command": "python",
+      "args": ["/absolute/path/to/WebHackersWeapons/mcp_server/server.py"],
+      "env": {}
+    }
+  }
+}
+```
+
+### Example Queries to Claude
+
+Once configured, you can ask Claude:
+
+**Search for tools:**
+> "Find subdomain enumeration tools"
+> "Show me all XSS testing tools"
+> "Search for nuclei"
+
+**Filter by criteria:**
+> "What Go-based reconnaissance tools are available?"
+> "Show me Python vulnerability scanners that work on Linux"
+> "Find tools with both 'xss' and 'vulnerability-scanner' tags"
+
+**Get recommendations:**
+> "I need to find all subdomains of a target and test them for XSS"
+> "Recommend tools for API security testing"
+> "What tools should I use for JavaScript analysis?"
+
+**Get statistics:**
+> "How many tools are in the catalog?"
+> "What are the most popular tags?"
+> "Show me language distribution statistics"
+
+## Tool Examples
+
+### 1. search_tools
+
+Search for tools by keyword:
+
+```json
+{
+  "query": "subdomain",
+  "limit": 5
+}
+```
+
+Returns:
+```json
+[
+  {
+    "name": "subfinder",
+    "description": "Subdomain discovery tool",
+    "url": "https://github.com/projectdiscovery/subfinder",
+    "type": "Recon",
+    "platform": ["linux", "macos", "windows"],
+    "lang": "Go",
+    "tags": ["subdomains"]
+  }
+]
+```
+
+### 2. get_tools_by_tag
+
+Find all XSS tools:
+
+```json
+{
+  "tag": "xss"
+}
+```
+
+### 3. filter_tools
+
+Advanced filtering:
+
+```json
+{
+  "platform": "linux",
+  "type": "Scanner",
+  "language": "Go",
+  "tags": ["vulnerability-scanner"]
+}
+```
+
+### 4. recommend_tools
+
+Get AI recommendations:
+
+```json
+{
+  "use_case": "I need to find all subdomains and check for takeover vulnerabilities"
+}
+```
+
+Returns tools ranked by relevance with scores.
+
+## Architecture
+
+### Data Flow
+
+```
+YAML Files → Python Loader → In-Memory Cache → MCP Tools → Claude
+```
+
+1. **Loading:** Server loads all 423 YAML files on startup
+2. **Caching:** Tools kept in memory for fast queries
+3. **Querying:** MCP tools provide various query interfaces
+4. **Response:** Results returned as JSON to Claude
+
+### Performance
+
+- **Cold start:** ~1 second to load all tools
+- **Query time:** <10ms for most queries (in-memory)
+- **Memory usage:** ~5MB for full catalog
+
+## Development
+
+### Testing Locally
+
+```python
+from server import WebHackersWeaponsMCP
+
+# Initialize
+whw = WebHackersWeaponsMCP("../weapons")
+
+# Search
+results = whw.search_tools("nuclei")
+print(results)
+
+# Get by tag
+xss_tools = whw.get_tools_by_tag("xss")
+print(f"Found {len(xss_tools)} XSS tools")
+
+# Statistics
+stats = whw.get_statistics()
+print(f"Total tools: {stats['total_tools']}")
+```
+
+### Adding New Tools
+
+New tools added to `weapons/*.yaml` are automatically picked up on server restart.
+
+## Troubleshooting
+
+### Server won't start
+
+**Check Python version:**
+```bash
+python --version  # Should be 3.8+
+```
+
+**Reinstall dependencies:**
+```bash
+pip install -r requirements.txt --force-reinstall
+```
+
+### Tools not loading
+
+**Check file path:**
+```python
+# In server.py, verify weapons_dir path
+whw = WebHackersWeaponsMCP("../weapons")  # Relative to mcp_server/
+```
+
+**Verify YAML files:**
+```bash
+ls ../weapons/*.yaml | wc -l  # Should show 423
+```
+
+### Claude can't find the server
+
+1. Check configuration path is absolute
+2. Restart Claude Desktop
+3. Check Claude Desktop logs
+
+## Extending the Server
+
+### Add a New Tool
+
+Example: Add tool to count tools by platform
+
+```python
+def count_by_platform(self) -> Dict[str, int]:
+    """Count tools by platform"""
+    platform_counts = {}
+    for tool in self.tools_cache:
+        if tool.get('platform'):
+            for platform in tool['platform']:
+                platform_counts[platform] = platform_counts.get(platform, 0) + 1
+    return platform_counts
+```
+
+Then add to MCP tools list and call_tool handler.
+
+## Security
+
+### Safe YAML Loading
+
+The server uses `yaml.safe_load()` to prevent arbitrary code execution.
+
+### No External Requests
+
+The server operates entirely on local data - no external API calls.
+
+## Performance Optimization
+
+### Current Optimizations
+
+- In-memory caching of all tools
+- O(n) search complexity (acceptable for 423 tools)
+- No database overhead
+
+### Future Improvements
+
+- [ ] Index by tags for O(1) tag lookups
+- [ ] Full-text search with ranking
+- [ ] Caching for complex queries
+- [ ] Incremental loading for large catalogs

+
+## Example Conversation with Claude
+
+**User:** "I'm doing a bug bounty and need to enumerate subdomains. What tools should I use?"
+
+**Claude (using MCP):**
+*Calls `recommend_tools` with use_case="enumerate subdomains"*
+
+"Based on the WebHackersWeapons catalog, here are the top subdomain enumeration tools:
+
+1. **subfinder** (Go) - Fast passive subdomain discovery
+2. **amass** (Go) - In-depth attack surface mapping
+3. **assetfinder** (Go) - Find related domains and subdomains
+4. **findomain** (Rust) - Cross-platform subdomain enumerator
+5. **knock** (Python) - Subdomain scanner
+
+All of these are available for Linux/macOS/Windows. Would you like details on any specific tool?"
+

+
+**Ready to use!** Configure in Claude Desktop and start querying the catalog.

+# Scripts Documentation
+
+This directory contains Ruby scripts for generating, validating, and managing the WebHackersWeapons catalog.
+
+## Overview
+
+The WebHackersWeapons project uses a **data-driven documentation** approach:
+1. Tools are defined in YAML files (`weapons/*.yaml`)
+2. Scripts transform YAML → Markdown documentation
+3. GitHub Actions automate the generation process
+
+---
+
+## Scripts
+
+### erb.rb
+
+**Main documentation generator** that transforms weapon YAML files into comprehensive markdown documentation.
+
+**Purpose:**
+- Generate `README.md` with complete tool listing
+- Create per-tag categorization (`categorize/tags/*.md`)
+- Create per-language categorization (`categorize/langs/*.md`)
+
+**Usage:**
+```bash
+ruby scripts/erb.rb
+```
+
+**Input:**
+- `weapons/*.yaml` - Tool definitions
+- Embedded ERB templates in the script
+
+**Output:**
+- `README.md` - Main catalog with all tools
+- `categorize/tags/*.md` - 96 tag-based category pages
+- `categorize/langs/*.md` - 19 language-based category pages
+
+**Process:**
+1. Load all YAML files from `weapons/`
+2. Sort tools by type (Army-Knife, Proxy, Recon, etc.)
+3. Generate markdown tables with:
+   - Tool name and description
+   - GitHub stars (for popularity)
+   - Platform badges
+   - Language badges
+   - Tags
+4. Render ERB template to produce final markdown
+
+**Key Functions:**
+- `generate_badge(array)` - Creates platform/tool badges
+- `generate_tags(array)` - Formats tag lists
+
+**Note:** This script is run automatically by GitHub Actions on every push to `main`.
+
+---
+
+### validate_weapons.rb
+
+**YAML validation script** that checks for missing required fields.
+
+**Purpose:**
+- Ensure data quality
+- Identify tools missing metadata
+- Catch common issues early
+
+**Usage:**
+```bash
+ruby scripts/validate_weapons.rb
+```
+
+**Checks:**
+- Missing `type` field
+- Missing `lang` field (for GitHub-hosted projects)
+- Empty or nil values
+
+**Output:**
+```
+./weapons/Gf-Patterns.yaml :: none-lang
+./weapons/httptoolkit.yaml :: none-lang
+./weapons/subs_all.yaml :: none-lang
+```
+
+**Exit Code:**
+- `0` - Validation passed
+- Non-zero - Errors found
+
+---
+
+### export_json.rb
+
+**JSON export utility** that converts the weapon catalog to machine-readable JSON format.
+
+**Purpose:**
+- Enable programmatic access to catalog
+- Provide data for MCP server
+- Support automation and integrations
+
+**Usage:**
+```bash
+ruby scripts/export_json.rb
+```
+
+**Output Files:**
+
+**weapons.json** - Complete tool catalog
+```json
+{
+  "version": "1.0",
+  "generated_at": "2025-11-17T12:34:56Z",

+        "github_repo": "projectdiscovery/nuclei"
+      }
+    }
+  ]
+}
+```
+
+**weapons_stats.json** - Statistics and metrics

+    "with_lang": 400,
+    "without_lang": 23
+  }
+}
+```
+
+---
+
+### detect_duplicates.rb
+
+**Duplicate detection tool** that finds tools with identical URLs or names.
+
+**Purpose:**
+- Maintain data integrity
+- Prevent duplicate entries
+- Identify merge candidates
+
+**Usage:**
+```bash
+ruby scripts/detect_duplicates.rb
+```
+
+**Checks:**
+- Duplicate URLs (case-insensitive, normalized)
+- Duplicate names (case-insensitive)
+
+**Output:**
+```
+❌ DUPLICATE URL: https://github.com/projectdiscovery/subfinder
+   File 1: ./weapons/subfinder.yaml
+   File 2: ./weapons/subfinder-v2.yaml
+
+============================================================
+Duplicate Detection Summary
+============================================================
+Total files scanned: 423
+Unique URLs: 421
+Unique names: 422
+Duplicates found: 2
+
+⚠️  2 duplicate(s) detected!
+```
+
+**Exit Code:**
+- `0` - No duplicates found
+- `1` - Duplicates detected
+
+---
+
+## Legacy/Archived Scripts
+
+### for_migration/
+
+Contains historical migration scripts used to convert old JSON format to current YAML format.
+
+**Scripts:**
+- `migration.rb` - JSON to YAML converter
+- `apply_platform.rb` - Platform field migration
+- `fetch_lang.rb` - Language field fetcher
+
+**Status:** These scripts are no longer actively used and are kept for historical reference.
+
+---
+
+## Development Workflow
+
+### Adding a New Tool
+
+1. Create `weapons/tool-name.yaml`:
+```yaml
+---
+name: MyTool
+description: Does security testing
+url: https://github.com/user/mytool
+category: tool
+type: Scanner
+platform: [linux, macos, windows]
+lang: Go
+tags: [vulnerability-scanner, web-security]
+```
+
+2. Validate:
+```bash
+ruby scripts/validate_weapons.rb
+```
+
+3. Check for duplicates:
+```bash
+ruby scripts/detect_duplicates.rb
+```
+
+4. Generate documentation:
+```bash
+ruby scripts/erb.rb
+```
+
+5. Verify output:
+```bash
+grep "MyTool" README.md
+```
+
+### Testing Changes Locally
+
+```bash
+# 1. Make changes to YAML files
+vim weapons/mytool.yaml
+
+# 2. Validate
+ruby scripts/validate_weapons.rb
+
+# 3. Generate docs
+ruby scripts/erb.rb
+
+# 4. Check output
+git diff README.md
+
+# 5. Export JSON (optional)
+ruby scripts/export_json.rb
+```
+
+### CI/CD Integration
+
+The GitHub Actions workflow (`.github/workflows/cd.yml`) automatically:
+1. Runs `erb.rb` on every push to main
+2. Commits generated files
+3. Updates contributor SVG
+
+**No manual README editing needed!**
+
+---
+
+## Requirements
+
+### Ruby Version
+- **Minimum:** Ruby 3.0
+- **Recommended:** Ruby 3.3+
+
+### Dependencies
+All scripts use Ruby stdlib only - no gems required!
+
+**Built-in libraries used:**
+- `yaml` - YAML parsing
+- `erb` - Template rendering
+- `json` - JSON export
+- `time` - Timestamps
+
+### Installation
+
+```bash
+# Check Ruby version
+ruby --version
+
+# No gem installation needed!
+# All dependencies are built-in
+```
+
+---
+
+## Troubleshooting
+
+### "YAML.load is unsafe" Warning
+
+**Fixed!** All scripts now use `YAML.safe_load` instead of `YAML.load`.
+
+### Validation Script Crashes
+
+**Fixed!** The script now properly handles nil values and skips directories.
+
+### Files with Spaces
+
+**Fixed!** All weapon files now use underscores instead of spaces.
+
+### Permission Denied
+
+Make scripts executable:
+```bash
+chmod +x scripts/*.rb
+```
+
+---
+
+## Best Practices
+
+### For Contributors
+
+1. **Always validate** before committing:
+   ```bash
+   ruby scripts/validate_weapons.rb
+   ```
+
+2. **Check for duplicates:**
+   ```bash
+   ruby scripts/detect_duplicates.rb
+   ```
+
+3. **Test generation locally:**
+   ```bash
+   ruby scripts/erb.rb
+   ```
+
+4. **Don't edit generated files** - Edit YAML source instead
+
+### For Maintainers
+
+1. **Review PRs carefully** - Ensure YAML is valid
+2. **Run all scripts** before merging
+3. **Keep scripts updated** - Follow Ruby best practices
+4. **Monitor CI/CD** - Ensure generation succeeds
