# MCP Server Security Firewall

MCP Server Security Firewall is a product idea in the devtools category at difficulty 4/5, with moderate market demand and an estimated revenue potential of $5k-15k/mo.

## Summary

A security firewall/proxy for AI coding agents and MCP servers that prevents injection attacks and malicious payloads. Targets teams using AI agents in production who need security guardrails.

## Why this is interesting

MCP (Model Context Protocol) adoption is accelerating fast as teams move AI coding agents into production workflows, and the attack surface is genuinely new — prompt injection through tool calls and malicious MCP server payloads are documented, real threats that most security tooling wasn't built to handle. No clear incumbent exists in this specific layer; existing WAF vendors like Cloudflare and traditional SAST tools don't address the MCP protocol surface. The $5k–15k/mo revenue band is plausible only if sold to mid-market engineering teams on a per-seat or per-agent basis, since security buyers at that spend level need a budget line, a compliance reason, or an incident to justify the purchase — none of which are guaranteed yet. The biggest risk is timing: MCP adoption may consolidate around a few managed platforms (Anthropic, Cursor, etc.) that bake in their own security controls, collapsing the independent tooling market before it forms.
