Greptile API for Merge Gates

Turning review logic into an API moves Greptile from selling seats to selling trust. The company already learns a team’s coding rules from pull requests, comments, accepted fixes, and uploaded style guides, then applies those rules across GitHub and GitLab reviews. Exposing that judgment layer through MCP lets agent products call Greptile after code is written, so Greptile can get paid whenever outside tools need a pass fail check before shipping code.

• This matters because coding agents are spreading across different surfaces. Cursor is pushing paid PR review through Bugbot, GitHub has added code review into Copilot plans, and Greptile already passes its repository context into tools like Cursor and Devin. An external validation layer fits a market where code generation and code checking are becoming separate jobs.

• The API can be sold to buyers Greptile does not reach with its core app. IDE vendors, CI systems, and autonomous agents do not need Greptile to own the full review workflow, they just need a service that says this change violates a security rule, breaks a team convention, or looks safe enough to merge.

• It also creates a cleaner competitive position against bundled review tools. GitHub Copilot and Cursor can bundle review inside larger subscriptions, while Greptile can specialize in deeper codebase context and custom rule enforcement. That is closer to infrastructure, where the value comes from being the checker other products rely on, not just another reviewer tab.

The next step is a shift from review assistant to merge gate for AI written code. As more software is produced by Cursor, Devin, Copilot, and similar agents, the highest value layer will be the system that sits at the end of the loop, checks every change against repository specific rules, and becomes embedded in CI, IDEs, and agent runtimes across the stack.
