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": {
    "diffsense": {
      "command": "uvx",
      "args": [
        "diffsense"
      ]
    }
  }
}

Run this in your terminal

claude mcp add diffsense -- uvx diffsense

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {

      "command": "uvx",
      "args": [
        "diffsense"

Open in VS Code

Common questions

Is DiffSense 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 (2.3.1) reached the registry 26 days 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?

DiffSense

DiffSense is a Change Risk Gate for the PR stage: it evaluates whether the current diff introduces regression risks without performing full codebase scans or style checks. Designed for minimal alerts, high precision, low latency, and interpretable results.

Quick Start

Scenario	Action
GitHub Pull Request	Copy the workflow from diffsense/docs/quickstart.md (Method 1) to `.github/workflows/diffsense.yml` in your target repository. Uses the default `GITHUB_TOKEN` with no additional configuration required. After committing and creating/updating a PR, the workflow will automatically execute the audit and post results under the PR.
Local Audit	Run `pip install -e diffsense` in the repository root, or `pip install "git+https://github.com/GoldenSupremeSaltedFish/DiffSense.git@main#subdirectory=diffsense"`, then execute `diffsense replay` .
Agent / LLM Integration	Install the MCP server with `pip install "diffsense[mcp]"` and run `diffsense-mcp`, or consume the JSON contract / SARIF directly. See Agent Integration Guide.

Complete steps are available at [diffsense/docs/quickstart.md](diffsense/docs/quickstart.md).

Optional: Add .diffsense.yaml to your repository root to use the officially recommended configuration, suitable for most teams.

Features

CI / Local: Performs semantic risk auditing on MR/PR diffs, outputting review_level and recommended actions. Analyzes only changed content without slowing down pipelines. Low-quality rules are automatically downgraded. Does not automatically modify CI status; decisions to block are made manually or by downstream processes.
Agent / LLM Integration: Deterministic, machine-readable surfaces for agents and CI gates — versioned JSON contract (schema_version), SARIF 2.1.0 output, and a read-only MCP server (audit_diff / audit_replay / list_rules / explain_rule). See the Agent Integration Guide and CLI Contract.
VSCode Extension: Maintained in the vscode-extension directory of this repository (dual-artifact layout). Install from the Marketplace or download the VSIX from Releases.

Quick Start (Detailed)

GitHub Actions

Copy the complete YAML from diffsense/docs/quickstart.md (Method 1) to your repository's .github/workflows/diffsense.yml to enable PR auditing.

GitLab CI

In your project, go to Settings → CI/CD → Variables and add the variable DIFFSENSE_TOKEN (Personal Access Token with api permissions; recommended to check Mask variable).
Add the corresponding job to .gitlab-ci.yml. See the example at diffsense/gitlab-ci-example.yml.

VSCode Extension

Maintained in the vscode-extension directory of this repository. Install from the Marketplace or download the VSIX from Releases.
