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

{

    "owasp-scan": {
      "command": "npx",
      "args": [

    }
  }
}

Run this in your terminal

claude mcp add owasp-scan -- npx -y @guardbee/mcp-owasp-scan

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {

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.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "owasp-scan": {

Common questions

Is Owasp Scan 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 (0.5.2) reached the registry 5 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@guardbee/mcp-owasp-scan

One CLI and MCP server for a unified [OWASP MCP Top 10](https://owasp.org/www-project-mcp-top-10/) check. It runs seven GuardBee auditors over a codebase in one pass, or grades a live MCP server's tool list, and reports every finding under its OWASP id with an A–F grade. Output as text, JSON or SARIF for GitHub code scanning.

Telemetry is off by default. With GUARDBEE_TELEMETRY=1 it sends the server, tool, success, duration and short parameter values such as a file path; longer strings and fields like content, token or password are replaced with a placeholder. See @guardbee/mcp-telemetry.

Quick start

# Static scan of a repository, fail CI on high or critical findings

npx @guardbee/mcp-owasp-scan scan ./src --format=sarif --fail-on=high > owasp.sarif

Connect to a running MCP server and grade its tools

npx @guardbee/mcp-owasp-scan live --url=https://mcp.example.com/mcp npx @guardbee/mcp-owasp-scan live --stdio=npx --arg=-y --arg=@modelcontextprotocol/server-filesystem --arg=.

Grade a saved tools/list response

npx @guardbee/mcp-owasp-scan catalog ./tools.json --format=json

As an MCP server (Claude Desktop, Cursor, VS Code):

"mcpServers": { "guardbee-owasp-scan": { "command": "npx", "args": ["-y", "@guardbee/mcp-owasp-scan"] } } }

Modes

Mode	Input	What runs
`scan`	A file or directory	secret-scanner, mcp-server-auditor, oauth-auditor, audit-gap-auditor, context-oversharing-auditor, toxic-flow-auditor, tool-poisoning-scanner
`live`	`--url=` or `--stdio=` with `--arg=…`	Connects, calls `tools/list`, then toxic-flow-auditor and tool-poisoning-scanner
`catalog`	A `tools/list` dump (`{ "tools": [...] }` or a bare array)	Same checks as `live`, offline

scan reads TypeScript/JavaScript, Python (FastMCP, official SDK, low-level server) and Go (official go-sdk, mark3labs/mcp-go) MCP servers in full: tool definitions, handler sinks and OAuth rules. Other languages (Rust, Java, Kotlin, C#, Ruby, PHP, Swift) get the language-neutral rules only (secrets, URLs, config). The report's coverage lists every source file with its language, that depth (full or patterns) and the number of tool definitions found, plus a per-language summary (languages: in text output), so a file the scan could not read deeply is visible rather than silently passing.

--discover-shadow adds an MCP09 check to scan: it inventories the MCP servers configured on this machine (Cursor, Claude Desktop, Windsurf, VS Code) through mcp-config-auditor, and --allowlist= marks the approved ones.

OWASP MCP Top 10 coverage

ID	Risk	Covered by
MCP01	Token / credential exposure	secret-scanner, mcp-server-auditor
MCP02	Privilege / excessive agency	mcp-server-auditor
MCP03	Tool poisoning / rug pull surface	tool-poisoning-scanner (`scan`, `live`, `catalog`)
MCP04	Supply chain	Not in this meta-scan: use `mcp-dependency-auditor` and `mcp-slopsquat-scanner`, which need the network
MCP05	Command / code injection via tools	mcp-server-auditor
MCP06	Prompt / context injection	Not in this meta-scan: use `mcp-prompt-injection-scanner` on the content an agent reads
MCP07	Auth / OAuth misconfiguration	oauth-auditor
MCP08	Lack of audit and telemetry	audit-gap-auditor
MCP09	Shadow MCP servers	mcp-config-auditor (`--discover-shadow`)
MCP10	Toxic flows / context oversharing	toxic-flow-auditor, context-oversharing-auditor (`scan`, `live`, `catalog`)

Grade

Grade	When
F	A lethal trifecta: one agent can read untrusted content, reach sensitive data and send data out
D	Any critical finding
C	Any high finding
B	Only medium or low findings
A	No findings

CLI options

Option	Default	Meaning
`--format=text\	json\	sarif`	`text`	Report format. SARIF uploads to GitHub code scanning
`--fail-on=any\	critical\	high\	medium\	none`	`any`	Exit 1 when a finding at or above this severity exists
`--max-files=`	`5000`	Stop a path scan after this many files
`--discover-shadow`	off	Add the MCP09 host inventory to `scan`
`--allowlist=`	–	Approved servers for `--discover-shadow`

Exit codes: 0 clean (or below --fail-on), 1 findings at or above --fail-on, 2 usage error.

MCP tools

Tool	What it does
`owasp_scan_path`	The `scan` mode over a path (`path`, `maxFiles`, `discoverShadow`, `allowlistPath`)
`owasp_scan_live`	The `live` mode (`url`, or `command` with `args`)
`owasp_scan_catalog`	The `catalog` mode on a JSON string
`list_owasp_coverage`	The coverage table above

Each auditor is also its own package with more options: mcp-secret-scanner, mcp-server-auditor, mcp-oauth-auditor, mcp-audit-gap-auditor, mcp-context-oversharing-auditor, mcp-toxic-flow-auditor, mcp-tool-poisoning-scanner, mcp-config-auditor. To enforce these rules at runtime instead of finding them in code, put mcp-security-proxy in front of your MCP servers.
