## How to find leaked keys and risky MCP servers on your machine with MCP Audit Tool

Repo: [graygnatconsole/mcp-audit-tool](https://github.com/graygnatconsole/mcp-audit-tool) | Difficulty: Intermediate | Time: 15 minutes | Basis: From the README

Scan every MCP config on a workstation and get a graded list of secrets and risky launch commands.

**Who it is for:** A developer who has added several MCP servers to Claude Desktop, Cursor, or VS Code and wants to know what those configs expose before the model runs them.

**The problem:** A single line in an MCP config can hold an API key in plaintext, fetch an unpinned package on every launch, or run a pipe-to-shell installer, and these are easy to miss by reading JSON by hand.

**The outcome:** A terminal report with a security score, a grade from A+ to F, each finding tied to a rule ID, and the top remediation steps to fix first.

### Steps

1. Install the tool with `pipx install git+https://github.com/graygnatconsole/mcp-audit-tool.git`.
2. Run `mcp-audit scan` to auto-discover and audit every MCP config on this machine.
3. Read the findings table and note every CRITICAL and HIGH row, starting with MAT-001 (hardcoded secrets) and MAT-004 (pipe-to-shell installers).
4. Move each exposed credential to a secrets manager and rotate it, then pin any unpinned npx, uvx, or pipx package to a known version.
5. Run `mcp-audit scan` again and confirm the score improved.

### Prompt to paste into your agent

```text
Use the GitHub repo graygnatconsole/mcp-audit-tool to run `mcp-audit scan <config-path>` on the MCP config at <config-path>. Return the score, grade, and a list of CRITICAL and HIGH findings with their rule IDs. Verify that the report lists each server name from the config file.
```

### Caveat

This is a static analyzer of config files, so it does not probe live servers, and the README roadmap lists runtime tool checks and auto-fix as planned, not built.

Risk, credentials: The configs being scanned often contain live API keys, so rotate any credential the report flags and avoid pasting raw config contents into shared chats or tickets.

## How to block risky MCP config changes in pull requests with MCP Audit Tool

Repo: [graygnatconsole/mcp-audit-tool](https://github.com/graygnatconsole/mcp-audit-tool) | Difficulty: Intermediate | Time: 30 minutes | Basis: From the README

Run the audit in GitHub Actions, fail the build on high findings, and show results in Code Scanning.

**Who it is for:** A team lead or DevSecOps engineer whose repository commits .vscode/mcp.json, .cursor/mcp.json, or similar project-level MCP configs.

**The problem:** Developers can add an MCP server with a plaintext HTTP endpoint, a wildcard permission, or a hardcoded token in a pull request, and nothing checks it before merge.

**The outcome:** Each pull request gets a SARIF upload that appears in the repository Security tab, and the workflow fails when a finding meets the severity threshold.

### Steps

1. Add a workflow file that sets `permissions:` with `security-events: write` and checks out the repository.
2. In the workflow, install the tool with `pipx install git+https://github.com/graygnatconsole/mcp-audit-tool.git`.
3. Run `mcp-audit scan .vscode/mcp.json .cursor/mcp.json --format sarif --output results.sarif` (adjust paths to your repo's MCP config files).
4. Add a step that uploads results.sarif with `github/codeql-action/upload-sarif@v3`.
5. Add `--fail-on high` to the scan command so the build fails on HIGH or worse findings, then open a test pull request to confirm the gate works.

### Prompt to paste into your agent

```text
Use the GitHub repo graygnatconsole/mcp-audit-tool to add a GitHub Actions workflow to <repo-path> that runs `mcp-audit scan` on the project MCP config files and writes SARIF output. Return the workflow file contents. Verify that the workflow has `security-events: write` permission and that the scan step includes `--format sarif`.
```

### Caveat

The README example uses `actions/checkout@v4`, `actions/setup-python@v5`, and `upload-sarif@v3`, so keep those versions unless you have checked them against your own runner setup.

## How to export a JSON audit report for team review with MCP Audit Tool

Repo: [graygnatconsole/mcp-audit-tool](https://github.com/graygnatconsole/mcp-audit-tool) | Difficulty: Intermediate | Time: 15 minutes | Basis: From the README

Produce a machine-readable JSON file from one or more MCP configs for scripts or tickets.

**Who it is for:** A security reviewer or platform engineer who must review MCP setups across several developer machines or projects and track results in their own tools.

**The problem:** Terminal output is hard to store, compare, or feed into a ticketing or reporting script, so reviews of many MCP configs stay manual.

**The outcome:** A JSON report file that a script or spreadsheet can parse, with findings tied to rule IDs such as MAT-010 and MAT-012.

### Steps

1. Install the tool with `pipx install git+https://github.com/graygnatconsole/mcp-audit-tool.git`.
2. Run `mcp-audit scan --format json --output report.json` to audit discovered configs and save the report.
3. To audit a specific file instead, run `mcp-audit scan ~/.cursor/mcp.json --format json --output report.json`. (inferred, check the README)
4. Run `mcp-audit rules` to list the rule IDs and severities so the team can map them to internal policy.
5. Open report.json and confirm each finding lists a rule ID, server name, and severity.

### Prompt to paste into your agent

```text
Use the GitHub repo graygnatconsole/mcp-audit-tool to run `mcp-audit scan <config-path> --format json --output report.json` on <config-path>. Return a summary table of findings grouped by severity. Verify that report.json exists and parses as valid JSON before summarizing.
```

### Caveat

The README does not describe the JSON schema field by field, so check a sample report.json before writing a parser that depends on specific keys.
