CAIN-42 CLAWXThe niche: MCP and AI tool security
Companies connecting agents to MCP servers, and companies publishing MCP servers who want a clean bill.
Why this niche exists now
- MCP became the standard way to connect agents to tools.
- Tool poisoning is a documented attack.
- Public MCP servers multiplied in 2025.
What people use today, and where it falls short
| What teams do today | Where it falls short |
|---|---|
| Read descriptions by eye | Invisible characters and long text hide things. |
| Trust the registry | Registries don't vet descriptions deeply. |
What makes MCP Security Scanner different
- Catches invisible characters and cross-tool tricks.
- Quarantine before the agent reads it.
- Human review in paid work.
How big is the opportunity?
Do not quote market-size statistics on a call. Most published figures are surveys or vendor estimates, and a smart buyer will ask for the source. Size the opportunity per prospect instead, with these questions:
- How many MCP servers do your agents use?
- Who reviewed their tool descriptions?
If the honest answers are "no" or "not yet", they are not a buyer today. Note it and move on; that is good selling, not failure.
