10 Powerful MCP Use Cases: Real-World Examples

Model Context Protocol (MCP) is transforming how developers, data analysts, and teams work with AI. But what can you actually do with it?

In this post, we'll explore 10 real-world use cases with concrete examples showing how MCP and ToolBoost can supercharge your workflows.

1. Code Review & Analysis

Scenario: You're a developer reviewing a pull request on GitHub.

Without MCP:

1. Open GitHub in browser
2. Read the PR description
3. Copy code snippets
4. Paste into Claude/ChatGPT
5. Ask for review
6. Copy response back to GitHub
7. Repeat for each file

With MCP (GitHub + ToolBoost):

Just ask your AI assistant:

"Review PR #247 in the api-server repo and suggest improvements"

What happens:

1. AI uses GitHub MCP to fetch PR details
2. Analyzes all changed files
3. Checks for code quality issues
4. Suggests improvements
5. Can even post review comments directly

Time saved: 15-30 minutes per PR

ToolBoost MCPs needed:

• GitHub MCP - Access repositories, PRs, and issues

---

2. Database Debugging & Analysis

Scenario: Your application is slow and you need to find problematic database queries.

Without MCP:

1. SSH into database server
2. Run EXPLAIN ANALYZE on queries
3. Copy results
4. Paste into AI
5. Ask for analysis
6. Implement suggested fixes
7. Test again

With MCP (Postgres + ToolBoost):

"Show me the slowest queries from the past hour and suggest optimizations"

What the AI does:

1. Queries pg_stat_statements via Postgres MCP
2. Analyzes slow queries
3. Suggests indexes or query improvements
4. Can even help implement changes

Example conversation:

You: "Why is the users table slow?"

AI (via Postgres MCP): "I see a full table scan on users for email lookups. You're missing an index. Here's the fix:

CREATE INDEX idx_users_email ON users(email);

This should improve query time from 2.3s to <10ms."

Time saved: 1-2 hours of debugging

ToolBoost MCPs needed:

• PostgreSQL MCP - Query and analyze databases
• MySQL MCP (if using MySQL)

---

3. Automated Documentation

Scenario: You need to document your codebase but it's tedious and time-consuming.

With MCP (Filesystem + GitHub):

"Read all files in /src/api and generate API documentation"

What happens:

1. Filesystem MCP reads your source files
2. AI analyzes function signatures, types, and logic
3. Generates comprehensive documentation
4. Can commit docs to your repo via GitHub MCP

Example output:

# API Documentation

## User Management

### GET /api/users
Retrieves a list of all users with pagination support.

**Parameters:**
- `page` (number, optional): Page number, defaults to 1
- `limit` (number, optional): Results per page, defaults to 20

**Returns:**
- `users` (array): List of user objects
- `total` (number): Total count
- `page` (number): Current page

Time saved: 4-8 hours per project

ToolBoost MCPs needed:

• Filesystem MCP - Read source files
• GitHub MCP - Commit documentation
