## Verification
### ✅ Parser Registration
**Code** (`src/ayga_mcp_client/server.py` lines 236-238):
```python
# Content Category (3 parsers)
{"id": "article_extractor", "name": "Article Extractor", ...},
{"id": "text_extractor", "name": "Text Extractor", ...},
{"id": "link_extractor", "name": "Link Extractor", ...}, # NEW
```
**Timeout Category** (line 24):
```python
"medium": {
"default": 120,
"parsers": [..., "article_extractor", "link_extractor"]
}
```
### ✅ Input Schema
**Code** (`src/ayga_mcp_client/server.py` lines 180-182):
```python
# Link Extractor - add preset enum
elif parser_id == "link_extractor":
schema["properties"]["preset"]["enum"] = ["default", "deep_crawl", "all_links"]
schema["properties"]["preset"]["description"] = "Preset: 'default' (single page, internal only), 'deep_crawl' (multi-level crawl), 'all_links' (internal + external)"
```
### ✅ Tool Generation
Tool automatically generated via `list_tools()`:
- Name: `extract_link_extractor`
- Description: "Extract all links from HTML pages with filtering and deduplication. Args: query (string), timeout (int, default 120)"
- Input schema: Includes query, timeout, preset with enum validation
### ✅ Handler
Universal handler in `call_tool()` automatically handles link_extractor:
- Matches tool name via prefix + parser_id
- Extracts parameters (query, timeout, preset)
- Calls `client.submit_parser_task()`
- Returns formatted result

## Testing
### Test File Created
**File**: `tests/test_link_extractor.py` (235 lines)
**Test Cases**:
1. ✅ Basic link extraction with default preset
2. ✅ All presets (default, deep_crawl, all_links)
3. ✅ Parser info retrieval
**Run Tests**:
```bash
export REDIS_API_KEY="your_key_here"
python tests/test_link_extractor.py
```
**Expected Output**:
```

## Usage Examples
### Basic Link Extraction
**Claude/Cursor**:
```
@ayga extract_link_extractor
query="https://maze.co/resources"
preset="default"
```
**Response**:
```json
{
"links": [
"https://maze.co/resources/article-1",
"https://maze.co/resources/article-2",
...
],
"total_count": 50,
"internal_count": 50,
"external_count": 0,
"source_url": "https://maze.co/resources"
}
```
### Deep Crawl
```
@ayga extract_link_extractor
query="https://example.com"
preset="deep_crawl"
timeout=180
```
### Agent Orchestration Workflow
```
User: "Собери все статьи с https://maze.co/resources"
Step 1: Claude Agent calls link_extractor
@ayga extract_link_extractor
query="https://maze.co/resources"
preset="deep_crawl"
Step 2: Agent processes links
For each link in response["links"]:
@ayga parse_article_extractor
query="{link}"
Step 3: Agent merges results
Combines all articles → saves to file
Output: "Saved 50 articles to maze_articles.md"
```
---
## Version Verification
### Package Version
```bash
python -c "import importlib.metadata; print(importlib.metadata.version('ayga-mcp-client'))"
# Output: 1.4.0
```
### Parser Count
```python
from ayga_mcp_client.server import PARSERS
print(f"Total parsers: {len(PARSERS)}")
# Output: Total parsers: 40
content_parsers = [p for p in PARSERS if "extractor" in p["id"]]
print(f"Content parsers: {len(content_parsers)}")
# Output: Content parsers: 3
```
---
## Agent Orchestration Architecture
### Why Agent Orchestration?
**Advantages** ✅:
1. **Flexibility**: Agent adapts to intermediate results
2. **Visibility**: Each step visible in chat
3. **Retry Logic**: Agent can retry failed steps
4. **Thin Client**: Business logic in agent, not client
5. **Extensibility**: Easy to add new parsers
**vs Built-in Flows** ❌:
- Hard-coded logic
- No visibility
- Difficult to debug
- Timeout risks
- Violates thin client principle
---
## Performance Metrics
### Code Changes
- **Lines Modified**: 5 (server.py)
- **Lines Added**: 235 (test file) + 200 (release notes)
- **Total New LOC**: ~440 lines
### Parser Stats
- **Total Parsers**: 40 (was 39)
- **Content Category**: 3 (was 2)
- **Timeout Category**: Medium (120s)
---
## Next Steps
### Deployment
**1. Build Package**:
```bash
cd t:\Code\python\A-PARSER\ayga-mcp-client
rm -rf dist/ build/
python -m build
```
**2. Test Locally**:
```bash
pip install -e .
python tests/test_link_extractor.py
```
**3. Publish to PyPI**:
```bash
twine check dist/*
twine upload dist/*
```
**4. Create GitHub Release**:
```bash
gh release create v1.4.0 \
--title "v1.4.0 - Domain Scraping Enhancement" \
--notes-file release_notes_v1.4.0.md \
dist/*.whl dist/*.tar.gz
```
### User Communication
