Installation

Prerequisites

• Python 3.10+

• pip package manager

• Virtual environment (recommended)

Setup

1. Clone or navigate to the project:

   cd /Users/tarunkumaruppu/AI/mcp-server

2. Create and activate a virtual environment:

   python3 -m venv venv
   source venv/bin/activate  # On Windows: venv\Scripts\activate

3. Install dependencies:

   pip install -r requirements.txt

4. Verify installation:

   python -c "from src.linkedin_client import LinkedInJobClient; print('✅ Installation successful!')"

Configuration

Rate Limiting

Control how frequently the server calls LinkedIn to prevent IP bans.

Default behavior: 2 seconds between requests

To customize:

# Via environment variable (override default)
export LINKEDIN_REQUEST_DELAY=3.0  # 3 seconds between requests
python src/index.py

# Or set in code (src/index.py, line ~35):
linkedin_client = LinkedInJobClient(request_delay=3.0)

Recommended values:

• 2.0 — Balanced (default)

• 3.0-5.0 — Conservative (safer)

• 1.0 — Aggressive (risk of bans)

VS Code Integration

1. Open VS Code settings (Cmd+, on macOS)

2. Search for "MCP Servers"

3. The server is pre-configured in .vscode/linkedin-mcp.json

4. Restart VS Code to enable

Or manually add to .vscode/settings.json:

{
  "mcpServers": {
    "linkedin-job-search": {
      "type": "stdio",
      "command": "python",
      "args": ["src/index.py"],
      "cwd": "/path/to/mcp-server"
    }
  }
}

Rate Limiting & Error Handling

How Rate Limiting Works

1. Request Throttle — Server waits LINKEDIN_REQUEST_DELAY seconds between API calls

2. Timestamp Tracking — Each request timestamp is logged for debugging

3. Sleep Before Request — If requests come too fast, the server sleeps to enforce delay

Common Errors & Solutions

❌ "LinkedIn rate limit reached"

Error: LinkedIn rate limit reached. Please wait 5-10 minutes before retrying.

Solution: Increase LINKEDIN_REQUEST_DELAY to 3-5 seconds, or wait and retry.

❌ "LinkedIn blocked the request (HTTP 403)"

Error: LinkedIn blocked the request (HTTP 403). Your IP may be temporarily banned.
       Wait 24-48 hours before retrying.

Solution: Your IP is temporarily blocked by LinkedIn. Wait 24-48 hours, then retry with higher delay.

❌ "Failed to search jobs"

Error: Failed to search jobs: [detailed error message]

Solution: Check your internet connection, keywords, and location. Review logs for details.

Logging

All requests and errors are logged to stdout with timestamps.

Log format:

2026-06-10 14:30:45,123 - src.linkedin_client - INFO - Searching LinkedIn for: Python Developer in San Francisco
2026-06-10 14:30:47,456 - src.linkedin_client - INFO - Found 25 jobs
2026-06-10 14:30:48,789 - src.index - INFO - Tool called: search_jobs with arguments: {...}

To adjust log level:

# In src/index.py, line ~20
logging.basicConfig(level=logging.DEBUG)  # For verbose output

Usage Examples

Example 1: Simple Job Search

Claude: "Find me Python developer jobs in San Francisco"

→ Tool Call: search_jobs(
    keywords="Python Developer",
    location="San Francisco, CA",
    limit=25
  )

→ Result: [25 job listings with titles, companies, salaries]

Example 2: Search with Filters

Claude: "Find senior-level data scientist jobs in NYC, full-time, posted in the last 7 days"

→ Tool Call: search_jobs(
    keywords="Data Scientist",
    location="New York, NY",
    job_type="full-time",
    experience_level="senior",
    hours_old=168,
    limit=20
  )

→ Tool Call: fetch_company_profile(company_name="Google")

→ Result: 
  LinkedIn URL: https://www.linkedin.com/search/results/companies/?keywords=Google
  Open Jobs: 142

Example 4: Multi-Step Job Hunt

Turn 1: Claude searches for jobs
  → search_jobs(keywords="ML Engineer", location="Remote", limit=30)
  
Turn 2: Claude asks for company info on top candidates
  → fetch_company_profile(company_name="Anthropic")
  
Turn 3: Claude filters results by salary
  → filter_jobs(salary_min=150000, salary_max=250000)

Performance & Limitations

Performance

Limitations

⚠️ JobSpy Limitations:

• Limited job description text extraction (full details require visiting LinkedIn URL)

• Company profile data is minimal (name, URL, job count only)

• Salary data may be incomplete on LinkedIn

⚠️ Rate Limiting:

• Default 2-second throttle means max ~30 jobs per minute

• LinkedIn may impose additional limits if too many requests from same IP

• No guaranteed uptime—LinkedIn can block access at any time

⚠️ Data Freshness:

• Job listings are real-time from LinkedIn

• Salaries and benefits may not be up-to-date

• Closed jobs may still appear briefly in results

Development

Project Dependencies

• mcp — Model Context Protocol SDK

• jobspy — LinkedIn job scraper

• pydantic — Data validation & type hints

• python-dotenv — Environment variable support

Code Structure

src/linkedin_client.py:

• LinkedInJobClient class — Main client with rate limiting

• JobListing Pydantic model — Job data structure

• CompanyProfile Pydantic model — Company data structure

src/index.py:

• MCP server setup and tool definitions

• Tool handlers (search, details, filter, company, categories)

• Error handling and formatting

Extending the Server

To add a new tool:

1. Define the tool schema in get_tools() (src/index.py)

2. Implement handler in linkedin_client.py

3. Add MCP handler in handle_call_tool() (src/index.py)

4. Document in this README

Example:

# 1. In linkedin_client.py
def my_new_feature(self, param: str) -> dict:
    """Implementation"""
    pass

# 2. In index.py, add to get_tools():
Tool(
    name="my_tool",
    description="...",
    inputSchema={...}
)

# 3. In handle_call_tool():
elif name == "my_tool":
    return await handle_my_tool(arguments)

# 4. Create handler:
async def handle_my_tool(arguments: dict):
    ...

Troubleshooting

Issue: ModuleNotFoundError: No module named 'mcp'

Solution:

pip install -r requirements.txt

Issue: Connection timeout to LinkedIn

Solution:

• Check internet connection

• Verify LinkedIn is accessible from your IP (not blocked)

• Increase LINKEDIN_REQUEST_DELAY to reduce request frequency

Issue: Empty search results

Solution:

• Try different keywords (LinkedIn may have strict matching)

• Expand location (try "United States" instead of specific city)

• Check if jobs exist on LinkedIn directly

Issue: Server won't start

Solution:

# Verify Python version
python --version  # Should be 3.10+

# Check dependencies
python -c "import mcp; import jobspy; print('OK')"

# Run with verbose logging
PYTHONUNBUFFERED=1 python src/index.py

Security Considerations

Current Implementation

✅ Parameterized inputs (no SQL injection risk)
✅ Request throttling (prevents IP bans)
✅ Graceful error handling (no sensitive info leakage)
✅ Local-only operation (no cloud storage)

For Production Use

⚠️ Consider adding:

• IP rotation for high-volume searches

• Request caching (SQLite) to reduce API calls

• User rate limiting (per-user request quotas)

• Audit logging (track who searches what)

• API key authentication (if exposing over network)

FAQ

Q: Will LinkedIn ban my IP?
A: Unlikely with the default 2-second throttle. LinkedIn allows scraping via JobSpy. Higher request rates or aggressive filtering may trigger temporary blocks (24-48 hours).

Q: Can I search all job boards at once?
A: No, this server is LinkedIn-only. Use JobSpy directly for multi-source searches.

Q: How many jobs can I search per day?
A: Unlimited theoretically, but LinkedIn may rate-limit or block after 1000+ requests/hour.

Q: Can I save job listings locally?
A: Not in this version. Extend with SQLite caching if needed.

Q: Does this tool post on LinkedIn?
A: No, it's read-only. Cannot apply to jobs, message recruiters, or modify profiles.
