Rosentic

rosentic/cursor-plugin

This server helps AI agents catch merge conflicts that standard CI misses by scanning multiple branches for incompatible changes. It exposes three MCP tools: check_conflicts runs deterministic AST analysis across branch heads to find broken function signatures, HTTP route collisions, and schema mismatches in 15+ languages. explain_conflict breaks down what went wrong and how to fix it. list_branches shows what's available to scan. You'd reach for this before opening a PR when working on a team where multiple feature branches touch the same APIs or data contracts. The analysis runs locally using tree-sitter, so no code leaves your machine. Think of it as a specialized linter that understands cross-branch compatibility rather than single-file code quality.

Rosentic - Cross-Branch Merge Safety

Rosentic checks whether your active branches are compatible with each other before merge. It detects broken function signatures, HTTP route conflicts, and schema mismatches across 15+ languages using deterministic AST analysis.

This is not AI code review. Rosentic finds structural contract conflicts that would cause runtime failures after merge - the kind of breaks that tests don't catch because they only run on one branch at a time.

Install

pip install rosentic-mcp

Then add to your editor's MCP config:

{
  "mcpServers": {
    "rosentic": {
      "command": "rosentic-mcp",
      "args": [],
      "env": {}
    }
  }
}

Works with Cursor, Claude Code, Cline, Windsurf, and any editor that supports MCP.

What it does

Rosentic gives your AI coding agent three MCP tools:

Tool	Purpose
`check_conflicts`	Scan a repo for cross-branch contract conflicts
`explain_conflict`	Explain a specific finding and what to do about it
`list_branches`	List active branches so the agent can choose what to scan
