# Or using pip
python -m venv venv
source venv/bin/activate # Windows: venv\Scripts\activate
pip install -e .

3. Set Environment Variable

# Linux/macOS
export PAGERDUTY_API_TOKEN="u+your-token-here"

# Or add to ~/.bashrc
echo 'export PAGERDUTY_API_TOKEN="u+your-token-here"' >> ~/.bashrc

⚙️ MCP Configuration

Claude Desktop

Config file: ~/.config/mcp/mcpServers.json (Linux) or ~/Library/Application Support/Claude/claude_desktop_config.json (macOS)

{
 "mcpServers": {
  "pagerduty": {
   "command": "uv",
   "args": [
    "--directory",
    "/path/to/pagerduty-mcp-server",
    "run",
    "python",
    "main.py"
   ],
   "env": {
    "PAGERDUTY_API_TOKEN": "${PAGERDUTY_API_TOKEN}"
   }
  }
 }
}

Claude Code (VS Code)

Config file: ~/.config/Code/User/mcp.json

{
 "mcpServers": {
  "pagerduty": {
   "command": "uv",
   "args": [
    "--directory",
    "/path/to/pagerduty-mcp-server",
    "run",
    "python",
    "main.py"
   ],
   "env": {
    "PAGERDUTY_API_TOKEN": "${PAGERDUTY_API_TOKEN}"
   }
  }
 }
}

Restart Claude Desktop/Code after config changes.

📖 API Reference

Incident Statuses

• triggered - New incident, not acknowledged
• acknowledged - Someone is working on it
• resolved - Incident fixed

Urgencies

• high - High urgency (pages on-call)
• low - Low urgency (notification only)

Common Fields

• incident_id - PagerDuty incident ID (e.g., Q26N8MQQHA6R0P)
• incident_number - Human-readable number (e.g., 2914407)
• service - Affected service
• assigned_to - List of assigned users
• html_url - Link to incident in PagerDuty web UI

---

🔒 Security

API Token Security

• ✅ Store token in environment variable (NOT in code)
• ✅ Use .gitignore to prevent token commits
• ✅ Token has same permissions as your PagerDuty user
• ✅ Audit trail: All actions logged with your email

Read-Only Tools

Safe to use without confirmation:

• list_incidents
• get_incident
• get_my_incidents
• get_incident_alerts
• get_incident_timeline
• get_oncall

Write Tools (Require Confirmation)

• acknowledge_incident - Marks incident as acknowledged
• resolve_incident - Closes incident
• add_incident_note - Adds investigation notes

---

🐛 Troubleshooting

"Missing PAGERDUTY_API_TOKEN"

# Check environment variable
echo $PAGERDUTY_API_TOKEN

# If empty, set it
export PAGERDUTY_API_TOKEN="u+your-token-here"
source ~/.bashrc

"Authentication failed"

• Token expired or invalid
• Get new token from PagerDuty User Settings
• Verify token starts with u+ or y1_

"No incidents found"

• Check filters (status, urgency)
• Verify you have access to incidents
• Try without filters: list_incidents(limit=10)

MCP Server Not Loading

• Restart Claude Desktop/Code
• Check config file path
• Verify uv is installed: uv --version
• Check logs: tail -f ~/.config/Claude/logs/mcp*.log

🎯 Use Cases

1. Morning Incident Check

"Show me all active PagerDuty incidents from the last 24 hours"

2. On-Call Handoff

"Who is currently on-call? Show all open incidents."

3. Incident Investigation

"Get incident Q26N8MQQHA6R0P details, alerts, and timeline"

4. Alert Analysis

"Show all alerts for incident XYZ and summarize the root cause"

5. Team Status

"List all triggered incidents for my team"
