MCP Tool Call Gating Proxy ·

If an entrepreneur "adopted" this product today, here's the realistic math.

Fermi summary

Land 45 paying teams at $300/mo and you hit $162k ARR - honest odds are about 13% you pull that off in year 1, and you'll burn ~$28k getting there regardless.

Market size (TAM)

$20.0M

~5,000 companies actively deploying MCP agents in production with compliance or security requirements × ~$4,000 avg annual spend on AI agent governance tooling

Year-1 ARR range

$24k - $480k

midpoint $160k

Gross margin

87%

Investment to production

$28k

Dev: $14k for hardened auth, billing, policy DSL, audit log UI. Docs/DX: $4k for integration guides and CLI tooling. Outbound marketing: $7k

Probability of success

13%

P(reaching mid case in 12 months)

Expected take-home Y1

$-9904

probability-weighted, after investment

Go-to-market motion

Developer-led bottom-up via MCP community, GitHub, and Hacker News → free tier with quota → upgrade to $200-500/mo per team when audit logging or policy rules hit limits → occasional enterprise pilot at $1,500-3,000/mo.

Key risks

Anthropic ships native tool call permissioning in their API or Claude.ai platform, eliminating the core value prop with zero notice
MCP-supporting clients (Cursor, VS Code, Windsurf) build gating natively into their agent runtimes, bypassing third-party proxies entirely
Developer buyers have very high DIY tolerance - OPA policies, custom middleware, or a weekend hack feels sufficient for most teams until their first incident
Enterprise procurement requires SOC2 Type II before signing any security-adjacent tooling contract, which takes 6-12 months and $15-25k to obtain
