What you can do with it
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
- Connection: Runs on your computer
- Transport: stdio
- Category: Other
Install
Pick the AI app you use, then copy the settings.
Before you install
- Basic checks: 1 of 1 passed
- Runs on your computer with your user’s permissions (files, network, apps).
- The registry lists no key to fill in.
You need
- PyPIPython’s uv installed (for the uvx command)
Which app do you use?
Pick your app above. We remember it, so next time the button says “Install in …”.
Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json
{
"mcpServers": {
"rosentic": {
"command": "uvx",
"args": [
"rosentic-mcp"
]
}
}
}Run this in your terminal
claude mcp add rosentic -- uvx rosentic-mcpOr copy the settings yourself
Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json
{
"mcpServers": {
"rosentic": {
"command": "uvx",
"args": [
"rosentic-mcp"
]
}
}
}Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.
Or copy the settings yourself
Paste into .vscode/mcp.json in your project

Common questions
Is Rosentic safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 6 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.
What can I use instead?

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-mcpThen 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 |
Example conflicts Rosentic catches
- Branch A adds a required parameter to
createOrder(). Branch B callscreateOrder()with the old signature. Both pass CI. Merge breaks production. - Branch A changes
POST /api/usersto requireemailin the request body. Branch B's frontend still sends the old payload. - Branch A removes a field from a GraphQL type that Branch B's query depends on.
How it works
Before you push, open a PR, or merge, your agent runs a cross-branch compatibility check. It calls check_conflicts, which scans your repo's branch heads using tree-sitter AST parsing and reports any conflicts.
No code leaves your machine. The scan runs locally against your git repo.
Compared to Semgrep Guardian
Semgrep Guardian checks each file for security vulnerabilities and code issues. Rosentic checks whether your branches are compatible with each other. They solve different problems and work well together:
- Semgrep Guardian: "Is this code safe and correct on its own?"
- Rosentic: "Will this branch break other branches when merged?"
