Run your on-call from your AI assistant

Connect in two minutes

You need an Oncallz account. In Claude, open the Oncallz directory listing, connect, and approve access in Oncallz. You can also add https://oncallz.com/mcp directly to a compatible client. The following manual setup uses a personal API token:

Connect Oncallz from the Claude directory

1. 1 Open Profile → API tokens and create a token with Full access. Pick an expiry — 90 days is a sensible default. The token is shown once; copy it.
2. 2 Add the server to your client (below), pasting the token where it says YOUR_TOKEN.
3. 3 Ask something. “What is the status?” is a good first question.

Claude Code

claude mcp add --transport http oncallz https://oncallz.com/mcp \
  --header "Authorization: Bearer YOUR_TOKEN"

Cursor and other clients with an mcp.json

{
    "mcpServers": {
        "oncallz": {
            "url": "https://oncallz.com/mcp",
            "headers": {
                "Authorization": "Bearer YOUR_TOKEN"
            }
        }
    }
}

Check it from a terminal

curl -s https://oncallz.com/mcp \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

You should get back the list of tools. A 401 means the token is wrong, expired or revoked; a 403 means it is a read-only feed token, which cannot use MCP.

OAuth uses your Oncallz login and asks you to approve access. You can revoke the connection from your profile. The token examples above remain supported, including for the mobile REST API.

Things to ask

• “Draft a post-mortem for the checkout incident using its timeline, add follow-up action items, and keep it unpublished.”
• “Is anything on fire right now?”
• “Who is on call tonight, and who is next weekend?”
• “Summarise the open critical incidents and what the AI analysis thinks caused them.”
• “Acknowledge the checkout incident and note that I am rolling back the deploy.”
• “Which post-mortem action items are overdue, and which are mine?”
• “What does the customer status page say right now?”
• “Yesterday the API was down from 10:15 to 10:45 Istanbul time. Record a resolved status-page incident, keep details internal but downtime public, and do not notify subscribers.”
