Hosting MCP servers

Hosted MCP listings run behind the AgentStack gateway, which authenticates each buyer’s entitlement and meters every call for usage billing. You choose how the server runs.

Option 1 — Self-hosted

You run the MCP server yourself (any cloud, any region). In the dashboard you register the upstream URL and an optional verify-header. The gateway authenticates, meters, and proxies each call to your endpoint — your code never runs on AgentStack.

Dashboard → Manage listing → Hosting → Self-hosted
  Upstream URL:   https://your-mcp.example.com/v1
  Verify header:  X-AgentStack-Secret: <your secret>

Option 2 — Managed by AgentStack

Don’t want to run infrastructure? AgentStack runs your container on Google Cloud Run with scale-to-zero. You provide a container image and configure scaling; we provision an isolated, least-privilege service and point the gateway at it.

• Fully configurable — container image, port, region, min/max instances, CPU (0.25–8 vCPU), memory, and request concurrency.
• Environment variables — including secrets, injected into your runtime.
• Scale-to-zero — min instances 0 means you pay nothing while idle. Raise it for warm starts.

Billing — cost passthrough + 10%

Managed hosting bills you the actual Cloud Run compute cost AgentStack incurs for your service, plus a 10% platform margin, charged monthly to your card on file. The dashboard shows a live estimate of the current month. A card on file is required before provisioning.

Monthly charge = Cloud Run compute cost × 1.10

Continuous deployment

Each managed deployment has a deploy token. Add one step to your CI after you build and push your image — it redeploys your Cloud Run service with the new image, no login required:

curl -X POST https://api.agentstack.voostack.com/api/hosted/deploy \
  -H 'content-type: application/json' \
  -d {"token":"$AGENTSTACK_DEPLOY_TOKEN","image":"gcr.io/you/mcp:$GIT_SHA"}

Find and rotate the token under Manage listing → Hosting. Keep it secret (treat it like a password).

How buyers connect

Either way, buyers point their agent client at the gateway with their license:

https://mcp.agentstack.voostack.com/mcp/<slug>

Every call is authenticated, metered, and (for usage-priced plans) reported to Stripe Billing Meters.
