How to monetize Networking & Infrastructure MCP servers with x402.

The test is simple: does the call consume your resources or the user's? Kubeshark MCP's traffic analysis — dissecting HTTP, gRPC, Kafka, and DNS flows in real time — is heavy computation that, offered as a hosted analysis endpoint, costs the operator per capture. ToolPipe's 45-tool utility belt (DNS lookups, screenshots, hashing) runs entirely on the host's infrastructure. Both are services; both can charge.

Domain and DNS servers like Porkbun DNS and spaceship-mcp sit in between: the user owns the domains, but you maintain the integration that makes registrar APIs agent-callable. The integration layer is the product.

Reads price at the floor: a DNS lookup, a cluster status check, or a container listing works at $0.01 and earns through ops agents' constant polling. Analysis is mid-tier — a traffic capture summary or a containerization plan from Containerization Assist involves enough compute to support $0.05–$0.25.

Mutations price by blast radius. A DNS record change, an SSL certificate operation, or a deployment through a Komodo-style stack manager affects production systems; agents' operators expect such calls to cost more, and $0.10–$0.50 per mutation signals appropriate gravity. Cheap destructive operations make operators nervous, not grateful.

An unpaid tool call returns HTTP 402 with the price; the agent's wallet signs and retries; USDC settles on Base in about two seconds; only then does your handler touch the cluster, registrar, or capture engine. Payment-before-execution means no free probing of infrastructure tools — relevant for a category where idle calls can still consume capture or API capacity. Settlement is final, with no chargebacks, and each response includes an Ed25519-signed receipt that slots neatly into the audit trails infrastructure teams already keep.

Loomal lists 64 networking and infrastructure servers. Claim yours by verifying GitHub ownership and connecting your remote endpoint, then set per-call pricing in the console — minimum $0.01, repriced in one field. The platform fee is 5% on settled transactions and is currently waived.

If your tool is local-only today (an SSH bridge to the user's router, say), the path to revenue is a hosted variant: a remote endpoint offering the analysis or integration parts of your tool as a service, with the local version remaining free.
