BIP Monitor MCP Server

A Model Context Protocol (MCP) server for monitoring Next.js development servers with intelligent error categorization, smart diagnostics, and performance tracking.

Features

• 🔍 Intelligent Error Categorization: Automatically categorizes errors into syntax, runtime, build, dependency, and port issues

• 💡 Smart Fix Suggestions: Provides actionable fix suggestions for each error category

• 📊 Performance Tracking: Monitors compile times and build performance metrics

• 💾 Persistent Logging: Errors persist across sessions in ~/.bip-monitor/

• 🔄 Real-time Monitoring: Live dev server monitoring with stdout/stderr capture

• 📡 MCP Resources: Access errors and status through standardized MCP resources

• 🛠️ MCP Tools: Control dev server and query errors programmatically

Installation

For Claude Code CLI

If your project has a .mcp.json file, add the server configuration:

{
  "mcpServers": {
    "bip-monitor": {
      "command": "npx",
      "args": ["-y", "bip-monitor-mcp"]
    }
  }
}

Or install locally in your project:

npm install bip-monitor-mcp

Then configure in .mcp.json:

{
  "mcpServers": {
    "bip-monitor": {
      "command": "node",
      "args": ["node_modules/bip-monitor-mcp/index.js"]
    }
  }
}

For Claude Desktop

Add to your Claude Desktop configuration:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "bip-monitor": {
      "command": "npx",
      "args": ["-y", "bip-monitor-mcp"]
    }
  }
}

Restart Claude Desktop to load the server.

MCP Resources

The server exposes the following resources:

bip://errors/recent

Returns the last 50 errors with categorization and summary statistics.

{
  "count": 10,
  "errors": [...],
  "summary": {
    "syntax": 3,
    "runtime": 2,
    "build": 1,
    "dependency": 0,
    "port": 0
  }
}

bip://app/status

Returns current dev server status including uptime and error count.

{
  "status": "running",
  "pid": 12345,
  "startTime": 1699564800000,
  "errorCount": 10,
  "lastError": {...},
  "uptime": 300000
}

bip://logs/full

Returns last 100 lines from stdout/stderr logs. For more control, use the get_logs tool.

bip://performance/metrics

Returns performance metrics including compile times.

{
  "lastCompileTime": 142,
  "avgCompileTime": 156,
  "compileTimes": [150, 142, 160, ...]
}

MCP Tools

start_dev_server

Start and monitor the Next.js dev server.

Parameters:

• cwd (string, required): Working directory for the app

Example:

{
  "name": "start_dev_server",
  "arguments": {
    "cwd": "/path/to/your/nextjs/app"
  }
}

get_errors

Get recent errors with optional filtering.

Parameters:

• limit (number, default: 10): Number of errors to return

• category (string, default: "all"): Filter by category (syntax|runtime|build|dependency|port|all)

get_status

Get current dev server status.

clear_errors

Clear the error log.

stop_dev_server

Stop the running dev server.

get_logs

Get application logs with flexible options.

Parameters:

• lines (number, default: 100, max: 2000): Number of lines to return from end of log

• filter (string, optional): Only return lines containing this text (case-insensitive)

Examples:

"Get the last 500 lines of logs"
"Get logs filtered by 'error' keyword"
"Get 1000 lines containing 'compile'"

Error Categories

Log Files

All logs are stored in ~/.bip-monitor/:

• errors.jsonl: Last 100 errors in JSON Lines format

• app.log: Complete stdout/stderr from dev server (access via get_logs tool)

• performance.json: Compile time metrics and performance data

Note: Use the get_logs tool to retrieve logs with custom line limits (up to 2000 lines) and optional text filtering.

Usage Examples

With Claude Code CLI

Read bip://errors/recent

With Claude API

const resource = await client.readResource('bip://errors/recent');
console.log(resource.contents[0].text);

Querying Errors

Use get_errors tool with limit=5 and category="syntax"

Starting Dev Server

Use start_dev_server with cwd="/Users/you/dev/my-nextjs-app"

Getting Logs

Use get_logs with lines=500
Use get_logs with lines=1000 and filter="error"
Use get_logs with filter="compile"

Development

Building from Source

git clone https://github.com/The-Bip-App/bip-monitor-mcp.git
cd bip-monitor-mcp
npm install

Running Locally

node index.js

The server communicates via stdio using the MCP protocol.

Requirements

• Node.js >= 18.0.0

• Next.js project with pnpm dev or npm dev script
