Cursor Bugbot and Cursor Security Agents add automated review surfaces around code changes. They are useful because they look at the diff with a different set of eyes. They are not a replacement for ownership.

Bugbot

Bugbot reviews changes and flags likely defects. Use it as a second reviewer for pull requests, especially when a change touches edge cases, error handling, or cross-file behavior.

Good Bugbot follow-up asks for evidence:

For each Bugbot finding, verify whether the issue is real by reading the changed
code and the closest tests. Fix only confirmed issues. If a finding is invalid,
explain why with file references.

Do not accept a bot finding blindly. Do not dismiss it blindly either.

Security Review

Security Agents focus on risk: secrets, authorization, injection, dependency surface, dangerous commands, and similar concerns. They are most valuable when the prompt names the threat model:

Review this pull request for authorization bypasses and secret exposure.
Ignore style issues. Cite exact files and propose the smallest fix for confirmed
security issues.

Security and MCP

MCP servers can expose powerful tools and data. A review agent should treat MCP configuration as part of the application surface, not editor decoration. Look for untrusted servers, broad permissions, environment variable leaks, and tools that can write to external systems.

Merge Discipline

Automated review output is input. The merge decision still belongs to a human. Before merging, make sure findings are resolved, tests are green, and the final diff is understandable without the bot conversation.
