// the skill your AI runs on
You are an application security reviewer for MCP servers and client configs who never runs untrusted code. You have been activated to find prompt injection, over-broad scopes and token leaks and to write the fixes.

What you're actually buying
MCP Security Reviewer checks an MCP server or client config before you connect it to Claude. Give it the server code, the tool definitions and your claude_desktop_config.json or connector settings, and it returns findings by severity with the file and line, the evidence, a short exploit scenario and the fixed code.
Built for developers shipping MCP servers and teams deciding which third-party servers to allow. It looks for prompt injection through tool results and descriptions, tool poisoning and silent description changes, over-broad scopes, token passthrough, tokens in logs or URLs, missing audience checks, SSRF, command injection and path traversal, unauthenticated remote endpoints, local servers exposed on 0.0.0.0, secrets in config files and unpinned packages. It is a static review and never runs an untrusted server; it reviews security rather than designing tools.
Finds the holes an attacker would use before an MCP server gets access to your files, inbox or production API.
Compatible with: MCP TypeScript and Python servers, Cloudflare Workers remote MCP, Claude Desktop and Claude Code configs, Claude.ai connectors and other MCP clients.
- What is MCP tool poisoning? Hidden instructions in a tool description or result that steer the model; the reviewer flags them with the exact text.
- Does it check OAuth? Yes - token audience, scopes, passthrough, storage and redirect handling.
- Can it review a server I did not write? Yes - paste the code or config; it never executes it.
- What do I get at the end? A findings table, a scope matrix per tool, a config review and a fix order.

この製品についての質問
What does MCP Security Reviewer do?+
It statically reviews MCP server code and client configs and returns findings by severity: prompt injection and tool poisoning, over-broad scopes, token passthrough and leaks, SSRF, command injection, path traversal, missing auth and secrets in config, each with location, evidence, an exploit scenario and a code fix.
What are the main MCP security risks?+
Untrusted text in tool results or descriptions that steers the model, tools with more access than the task needs, tokens passed through or logged, remote endpoints without proper OAuth, local HTTP servers open to the network, and install commands that pull unpinned packages.
Does it check MCP OAuth and token handling?+
Yes. It checks that tokens are issued for your server and validated for audience, that scopes match each tool, that upstream tokens are never passed through, and that tokens never appear in logs, URLs or config files.
Is it the same as an MCP builder or tool-design skill?+
No. Builders write and deploy servers and tool-design skills tune schemas. This skill attacks the design on paper and tells you what to fix before anyone connects it.
