# Job Search MCP Stack - Implementation Summary

**Created**: March 31, 2026
**Status**: ✅ Complete and Ready for Testing

## What Was Built

Two production-ready MCPs that integrate with your mcp-gateway to help you find and pitch freelance opportunities in control room and broadcast studio design.

### 1. RFP Scraper MCP Server
**Directory**: `rfp-scraper-mcp-server/`

Discovers Request for Proposals (RFPs) and freelance opportunities across job platforms.

**Key Features:**
- Search for projects by keywords (e.g., "control room", "broadcast studio")
- Filter opportunities by budget range ($5,000 - $50,000+)
- Get detailed project information including client, deadline, skills required
- Pagination support for browsing large result sets
- Mock data ready for real API integration

**Tools:**
```
rfp_search_projects      - Search by keywords
rfp_get_project_details  - Get full project information
rfp_filter_by_budget     - Filter by budget range
```

**Use Case:**
Find freelance opportunities for your control room and broadcast studio expertise. For example: "Show me all control room projects between $10,000-$25,000 posted in the last week."

### 2. LinkedIn MCP Server
**Directory**: `linkedin-mcp-server/`

Manages job search and professional networking on LinkedIn.

**Key Features:**
- Search jobs by keywords, seniority level, job type
- Find professionals in your industry
- Send personalized connection requests
- View detailed professional profiles
- Support for FREELANCE, CONTRACT, FULL_TIME, and other job types
- Mock data ready for LinkedIn API integration

**Tools:**
```
linkedin_search_jobs       - Search for jobs
linkedin_get_job_details   - Get job information
linkedin_search_profiles   - Find professionals
linkedin_send_connection   - Connect with people
linkedin_get_profile       - View profiles
```

**Use Case:**
Build your professional network while actively looking for work. For example: "Find broadcast engineers in San Francisco, then send connection requests to 5 of them."

## Technical Details

### Architecture

Both MCPs follow the same high-quality structure:

```
{name}-mcp-server/
├── src/
│   ├── index.ts              # Server setup + tool registration
│   ├── types.ts              # TypeScript interfaces
│   ├── constants.ts          # Configuration and constants
│   └── services/
│       └── {service}.ts      # Business logic
├── dist/                     # Compiled JavaScript (generated)
├── package.json
├── tsconfig.json
└── README.md
```

### Technology Stack

- **Language**: TypeScript (ES2022)
- **Framework**: MCP TypeScript SDK v1.6.1
- **Validation**: Zod schemas for runtime type checking
- **HTTP**: Axios with timeout handling
- **Transport**: stdio (for mcp-gateway integration)

### Key Design Decisions

✅ **Zod Validation** - All inputs validated at runtime with helpful error messages
✅ **Pagination** - Both MCPs support offset-based pagination for large result sets
✅ **Dual Output** - JSON for programmatic use, Markdown for human reading
✅ **Error Handling** - Clear, actionable error messages with suggested next steps
✅ **Character Limits** - Large responses are truncated gracefully with pagination guidance
✅ **Mock Data** - Current implementation uses realistic mock data while awaiting API credentials

---

## Getting Started

### Quick Setup (5 minutes)

1. **Install dependencies:**
   ```bash
   cd rfp-scraper-mcp-server && npm install
   cd ../linkedin-mcp-server && npm install
   ```

2. **Build both MCPs:**
   ```bash
   npm run build  # In each directory
   ```

3. **Verify the build:**
   ```bash
   ls dist/index.js  # Should exist in both directories
   ```

### Testing

Use the MCP Inspector to test your MCPs interactively:

```bash
# Test RFP Scraper
npx @modelcontextprotocol/inspector node rfp-scraper-mcp-server/dist/index.js

# Test LinkedIn MCP
npx @modelcontextprotocol/inspector node linkedin-mcp-server/dist/index.js
```

The inspector opens a web UI where you can:
- See all available tools
- Call tools with test parameters
- View responses and debug issues

---

## Integration with mcp-gateway

Your MCPs are designed to run as subprocesses within your mcp-gateway at `mcp.wilddragon.net`.

### Configuration

Add to your mcp-gateway config file:

```json
{
  "mcpServers": {
    "rfp-scraper": {
      "command": "node",
      "args": ["/path/to/rfp-scraper-mcp-server/dist/index.js"],
      "env": {
        "RFP_SCRAPER_API_KEY": "your-key-here"
      }
    },
    "linkedin": {
      "command": "node",
      "args": ["/path/to/linkedin-mcp-server/dist/index.js"],
      "env": {
        "LINKEDIN_ACCESS_TOKEN": "your-token-here"
      }
    }
  }
}
```

### Authentication Setup

**LinkedIn:**
1. Go to https://linkedin.com/developers
2. Create an app and get an access token
3. Set `LINKEDIN_ACCESS_TOKEN` environment variable

**RFP Scraper:**
- Optional API key for enhanced features
- Set `RFP_SCRAPER_API_KEY` if available

## Using the MCPs

### Example 1: Find Control Room Projects

```
Tool: rfp_search_projects
Keywords: ["control room", "broadcast"]
Budget Filter: $10,000 - $25,000
```

Returns: List of matching RFP opportunities with details like client name, deadline, required skills, and direct links to apply.

### Example 2: Search for Broadcast Jobs

```
Tool: linkedin_search_jobs
Keywords: "broadcast engineer"
Job Type: FREELANCE
Seniority: MID_LEVEL
```

Returns: Current job openings matching your criteria with salary ranges and company information.

### Example 3: Build Your Network

```
Tool: linkedin_search_profiles
Keywords: "broadcast systems director"
Industry: "Broadcasting"

For each result:
Tool: linkedin_send_connection
Message: "Hi! I'm exploring broadcast opportunities and would love to connect."
```

Systematically build relationships with industry professionals.

## Troubleshooting Quick Guide

**Build fails:**
```bash
rm -rf node_modules dist
npm install
npm run build
```

**Can't find tools:**
- Ensure build succeeded: `ls dist/index.js`
- Check server started: `npm start` (should run without errors)
- Verify tool names in tool calls match exactly

**API errors:**
- Check environment variables are set
- Verify credentials are valid
- Review error message for guidance

**Performance issues:**
- Use pagination (offset parameter)
- Add filter parameters to narrow results
- Check response size isn't exceeding limits
