Build an MCP Security Gateway for AI Agents
11/15The Opportunity
Spotted on Product Hunt · March 19, 2026
As AI agents adopt MCP to call external tools, there is no access control layer. Developers shipping agents to enterprises need auth and audit trails.
Why these scores?
Demand (pain) scored 4/5 (very high) — how urgently people need a solution.
Willingness to pay scored 4/5 (very high) — evidence people would pay for this.
Market gap scored 4/5 (very high) — how underserved this space is.
Build effort scored 3/5 (strong) — feasibility for a solo builder or small team.
Who's Complaining About This?
Willingness to Pay
Permit.io MCP Gateway launched on Product Hunt to 98 upvotes on day one. Enterprise security buyers pay $500-5000/mo for access control tooling. Timing is early — MCP is just becoming mainstream.
Score Breakdown
11/15How urgently people need this solved and how willing they are to pay for it. Based on complaint frequency and spending signals across platforms.
How open the market is. A high score means few or no direct competitors, or existing solutions are overpriced and underdeliver.
How quickly a solo developer can ship an MVP. 5 = weekend project with standard tools. 1 = months of infrastructure work.
Existing Solutions
Permit.io (just launched, enterprise), no indie-priced MCP security layer. Wide open for a cheaper developer-focused option.
