meok-mcp-injection-scan-mcp

Scan any MCP server for the prompt-injection / tool-poisoning / SSRF class disclosed in the April 2026 CVE wave.

pip install meok-mcp-injection-scan-mcp

Why this exists

April 2026 was a bad month for MCP. Anthropic published a "by-design" MCP RCE class affecting ~7,000 public servers (~150M downloads). mcp-server-git shipped a CVE chain. DockerDash got popped by an injection chain. Tool-description prompt injection ("tool poisoning") was demonstrated against every major MCP host.

If you run an MCP server in production, or you're auditing one before adoption, you need a fast scan that flags the patterns the April 2026 disclosures target. This MCP is that scan.

What it checks

30+ canonical rules across 5 severity tiers:

• CRITICAL — direct RCE, system-prompt override, credential exfil patterns, shell metachars in defaults, file:// / internal-network URLs (the DockerDash 169.254.169.254 metadata-pivot vector).
• HIGH — encoded payloads, imperative directives at the agent, supply-chain prompts, env-var references, tool shadowing.
• MEDIUM — urgency / authority language, additionalProperties=true, unbounded strings, tool-name impersonation.
• LOW — over-long descriptions, zero-width / bidi-override chars (the U+202E PoC vector).

Coverage maps to: OWASP LLM Top 10, GenAI Red Team v1, the April 2026 Anthropic MCP RCE disclosure, and the mcp-server-git CVE chain.

Tools exposed

Tool	Purpose
scan_mcp_url(url)	Fetch a remote MCP server's tool listing and scan it
audit_tool_descriptions(tools_json)	Scan a pasted JSON tool list (auth-walled servers)
signed_safety_report(subject, findings_json, score, note)	Issue a procurement-grade signed cert (Pro tier)
list_rules()	Inspect the full rule catalogue before subscribing
pricing()	Subscribe links + tier comparison

Pricing

Tier	Price	What you get
Free	£0	5 scans / day, no signed reports
Starter	£29/mo	Unlimited scans + signed reports
Pro	£79/mo	+ scheduled rescans + 48h support
Enterprise	£1,499/mo	+ custom rule packs + 4h SLA

Every signed cert lives at https://meok-attestation-api.vercel.app/verify/<cert_id> — auditors and procurement teams confirm without an account.

What you do NOT get

This is a static-pattern scanner. It does not run dynamic taint analysis, fuzz the server with adversarial inputs, or replace a human red-team. It is the first 80% of the audit, in 5 seconds, for free.
