Monzo's self-built Slack coding agent Chip can handle more than 1,800 tasks per day on average and contributes over 10% of merged PRs across all engineering teams.
Monzo maintains more than 3,000 backend services, about 13,000 data warehouse models, and dozens of machine learning predictors.
Before Agent Chip appeared in the form of a remote agent, Monzo had already built its own MCP gateway to uniformly expose internal services and knowledge sources, perform deterministic filtering, and manage agent authentication and authorization.
Monzo's internal ask channel lets Agent Chip participate in cross-team information flow; it can draft replies based on knowledge sources, directly resolving requests when the information is sufficient and pulling in humans to supplement when it is not.
Agent Chip significantly lowers the barrier for non-specialist roles at Monzo to participate in system building, but it states that this does not change the rigor with which Monzo develops software, and the chain of responsibility for review, testing, and deployment remains intact.
Agent Chip's architecture completely isolates the agent runtime from production infrastructure; non-determinism occurs only in the innermost sandbox, and all external boundaries are controlled by deterministic rules.
Monzo believes Agent Chip's long-term value comes from three judgments: composability, provider independence, and the continuously expanding development window.
At the AI Engineer conference, a Monzo engineer asked whether a company that has not yet built its own AI coding toolchain can still count as a serious tech company.
