Failures, incidents and rollbacks1

Eugene LevitinFounderDocka
A startup that tests whether AI agents finish real jobs in SaaS products. One monday.com job run in Copilot Studio, Oct 5, 2026.
GitHub, mondaycom/mcp, published Oct 5, 2026Read the issue (opens GitHub, mondaycom/mcp in a new tab)
Observation
At Docka, a monday.com job in Copilot Studio failed in all 3 runs with GPT-5.5 Chat on the MCP URL path, because Copilot Studio kept only the first 70 tools.
Takeaway
Test each MCP server through the same path and model your agent will use in production. Count the tools the server lists, because tools past the 70th never reach the model.
What happened
The same monday.com job passed 6 of 6 runs through the certified connector and 3 of 3 with Claude Sonnet 4.6 on the MCP URL path, but failed 0 of 3 with GPT-5.5 Chat there and created nothing. Copilot Studio's transcripts showed it kept only the first 70 tools the server listed, so the search tool, now 85th, never reached the model, and GPT-5.5 Chat asked the user for GraphQL variables and never sent the call.

Australia's largest bank, retail customer experience centre. A contact centre fielding about 50,000 phone calls a day. Telco News report, Jul 10, 2026.
Telco News, published Jul 10, 2026Read the report (opens Telco News in a new tab)
Observation
Commonwealth Bank rolled out a contact centre platform built with Microsoft, after migrating nearly 700 chatbot topics into Copilot Studio.
Takeaway
Route by risk before intent. CommBank keeps regulated processes on fixed paths and sends vulnerable customers to people, and lets agents take the rest.
What happened
CommBank phased out its existing virtual chatbot, migrated nearly 700 chatbot topics into Copilot Studio and launched a generative AI banking chatbot in late 2024. The platform, co-engineered with Microsoft, routes each request to a bot, an answer drawn from public content, a fixed path for regulated matters such as fraud disputes, or a human specialist when a customer's language shows vulnerability. The bank says it handles more than 2 million conversations a month, and that about 84.6% of self-service messaging interactions in May 2026 were resolved end to end in the channel.

Observation
Westpac uses Copilot Studio across the bank in two tiers: a default environment for personal agents and a governed space for enterprise apps.
Takeaway
Governance built for Power Platform carries over to agents. Settle environments and an automated intake before opening Copilot Studio to citizen developers.
What happened
Westpac is rolling out Copilot Studio so teams across the business can build agents in a governed environment. One early use embeds agents in SharePoint so bankers can question pre-built dashboards in natural language, which principal engineer Smitha Janarthanan stated already brings productivity gains. Simon Gobbo stated that the bank's earlier Power Platform governance made adoption relatively straightforward. Staff build personal agents in a default environment and must pass an automated intake, the bank's digital front door, to reach the enterprise environment.
