pcp-mcp

MCP server for Performance Co-Pilot (PCP) metrics.

Query system performance metrics via the Model Context Protocol - CPU, memory, disk I/O, network, processes, and more.

📖 Full Documentation | 🚀 Getting Started

🚀 Quick Start (No Install)

Run immediately with uvx — no installation required:

uvx pcp-mcp

Or install as a persistent global tool:

uvx tool install pcp-mcp
pcp-mcp

📦 Installation

pip install pcp-mcp

Or with uv:

uv add pcp-mcp

📋 Requirements

Python: 3.10+

PCP: Performance Co-Pilot with pmcd and pmproxy running

# Fedora/RHEL/CentOS
sudo dnf install pcp
sudo systemctl enable --now pmcd pmproxy

# Ubuntu/Debian
sudo apt install pcp
sudo systemctl enable --now pmcd pmproxy

⚙️ Configuration

Configure via environment variables:

Variable	Description	Default
`PCP_HOST`	pmproxy host	`localhost`
`PCP_PORT`	pmproxy port	`44322`
`PCP_TARGET_HOST`	Target pmcd host to monitor	`localhost`
`PCP_USE_TLS`	Use HTTPS for pmproxy	`false`
`PCP_TLS_VERIFY`	Verify TLS certificates	`true`
`PCP_TLS_CA_BUNDLE`	Path to custom CA bundle	(optional)
`PCP_TIMEOUT`	Request timeout (seconds)	`30`
`PCP_USERNAME`	HTTP basic auth user	(optional)
`PCP_PASSWORD`	HTTP basic auth password	(optional)
`PCP_ALLOWED_HOSTS`	Hostspecs allowed via host param	(optional)

🎯 Usage

Monitor localhost (default)

pcp-mcp

Monitor a remote host

PCP_TARGET_HOST=webserver1.example.com pcp-mcp

Or use the CLI flag:

pcp-mcp --target-host webserver1.example.com

Connect to remote pmproxy

PCP_HOST=metrics.example.com pcp-mcp

Use SSE transport

pcp-mcp --transport sse

🔌 MCP Client Configuration

Claude Desktop

Add to ~/.config/claude/claude_desktop_config.json:

{
  "mcpServers": {
    "pcp": {
      "command": "uvx",
      "args": ["pcp-mcp"]
    }
  }
}

For remote monitoring:

{
  "mcpServers": {
    "pcp": {
      "command": "uvx",
      "args": ["pcp-mcp", "--target-host", "webserver1.example.com"]
    }
  }
}

💡 Using uvx means you don't need pcp-mcp installed — it runs directly from PyPI.

🛠️ Available Tools

System Monitoring

get_system_snapshot - Point-in-time system overview (CPU, memory, disk, network, load)
get_process_top - Top processes by CPU, memory, or I/O usage
query_metrics - Fetch current values for specific PCP metrics
search_metrics - Discover available metrics by name pattern
describe_metric - Get detailed metadata about a metric

Example Queries

"What's the current CPU usage?"
→ Uses get_system_snapshot

"Show me the top 10 processes by memory usage"
→ Uses get_process_top(sort_by="memory", limit=10)

"What metrics are available for network traffic?"
→ Uses search_metrics(pattern="network")

"Get detailed info about kernel.all.load"
→ Uses describe_metric(name="kernel.all.load")

💡 Use Cases
