Get a second-opinion code review from Claude Code over MCP
Your coding agent is good at reviewing code. It is less good at reviewing its own code: it reads the change with the same prompt, the same context and the same assumptions that produced it. For risky changes (authentication, payments, data deletion) a reviewer from outside that loop is worth having. This post shows how to ask an independent AI agent for a review from inside Claude Code, using the…
In a world where AI can now assist with code reviews, a new method has emerged to ensure accuracy and objectivity. The Model Context Protocol (MCP) allows for independent AI agents to review code outside of the traditional loop, providing a second opinion on potentially risky changes.
To begin, add a remote MCP server using the claude mcp add command, specifying the transport protocol, scope, and the URL of the MCP server. In this example, the Speedbot.dev MCP server is used as a read-only planning operation. Once the connection is confirmed, request a read-only plan from Claude Code, specifying the desired review details such as the independent code review of changes in a specific pull request.
The reviewer will return a prioritized report with file and line references, the checks performed, and any unverified aspects.
Craft a brief for the reviewer, including the repository, pull request, expected behavior, and test commands. Clearly state what constitutes a satisfactory outcome and what should not be shared, such as secrets or private data. Before accepting the review, run the provided test command and verify high-impact findings at the referenced lines. If a finding lacks a reproducible check, treat it as a hypothesis rather than a confirmed defect.
After receiving the second review, compare it with the original review and the initial one. Keep only the findings that have been verified and note any checks that require additional access or context. The read-only plan serves as an effective way to test the MCP setup and ensure the reviewer receives the appropriate scope. Keep in mind that Speedbot.dev maintains the example MCP server used in this example.
