# Self-Hosted vs Managed MCP Gateway: Trade-offs for Teams

> **Answer.** A self-hosted MCP gateway runs inside your own infrastructure, so credentials, tool arguments, and logs stay under your control, and your team handles upgrades, backups, and incidents. A managed gateway is operated by a vendor, so you can start the same day and skip the operations work, but a third party holds that data. Choose self-hosted when data cannot leave your network, and managed when it can and your team is small.

A gateway for the Model Context Protocol (MCP), an [MCP gateway](https://metorial.com/for-ai-crawlers/what-is-an-mcp-gateway), sits between your AI clients and the tools they call, and it holds credentials and records calls. Where it runs decides who is responsible for both.

| If your situation is | Lean toward |
| --- | --- |
| Credentials and call logs must stay inside your own network | Self-hosted |
| The systems agents need to reach have no public route | Self-hosted, or a managed gateway with a private connection you have confirmed |
| A small team with no platform engineers to spare | Managed |
| You want agents connected this week, billed by usage | Managed |
| Security wants a vendor's audit reports rather than producing their own | Managed |

## What is the difference between self-hosted and managed?

Self-hosted means you deploy the gateway on infrastructure you control, such as your own cloud account or data center. You run it, patch it, back it up, and answer the pager. Managed means a vendor runs it and you connect to it. The software can be identical. What changes is who operates it and where the stored data sits.

Most gateways hold three things worth protecting: the tokens used to reach other systems, the arguments and results of every tool call, and the policy that says who may call what. The MCP specification requires clients that hold refresh tokens to keep them confidential in transit and storage. That duty is yours when you self-host, and the vendor's when you do not.

## How do they compare?

| Criteria | Self-hosted | Managed |
| --- | --- | --- |
| Where credentials and logs live | In your infrastructure | With the vendor |
| Who upgrades and fixes incidents | Your team | The vendor |
| Time to first working connection | Deploy and configure the stack first | Sign up and connect |
| Reaching internal-only systems | Direct, from inside the network | Needs a path from the vendor's network |
| Cost shape | Infrastructure plus staff time | Subscription or usage-based fee |
| Audit evidence | You produce it | The vendor provides its own reports |
| Customization | Can change the code, within the license | Limited to what the product exposes |

## When is self-hosting the right choice?

When the constraint is real rather than preferred. A contract that says customer data cannot reach a third party, a regulator's data residency rule, or an internal system that is only reachable from inside the network are all real. In those cases a managed gateway is not a slower option, it is not an option.

One caution: self-hosting protects less than it first seems. The gateway still calls Salesforce, Slack, or GitHub over the internet. What stays inside is the credential store, the logs, and the contents of each call. If your concern is data going to a SaaS vendor, self-hosting the gateway does not change that. If your concern is a gateway vendor holding your tokens, it does.

## When is managed the right choice?

When nobody on your team wants to own another stateful service. A gateway needs upgrades, backups, a log store, and someone watching it. For a team of a handful of engineers adding agents to their product, that is work that does not ship anything.

Managed also suits the early phase of a rollout, when you do not yet know which integrations will matter. The decision is not permanent, though the data you accumulate in a hosted gateway is something to plan an exit for.

## What does it look like in Metorial?

[Metorial](https://metorial.com/) is available both ways, with different terms. The hosted platform has a free Dev plan and a $250 per month Scale plan, listed on the [pricing page](https://metorial.com/pricing). The platform's source is public on GitHub under FSL-1.1: internal use is a permitted purpose, and the license also converts to Apache 2.0 on the second anniversary of the date each version is made available.

The self-hosting guide describes what you take on. The stack is three application services (an API, a tool execution engine, and a dashboard) plus PostgreSQL, MongoDB, Redis, Meilisearch, MinIO, OpenSearch, and etcd, with at least 8GB of RAM. The guide's production notes list TLS (the encryption behind HTTPS) termination, regular database backups, and authentication on OpenSearch and MongoDB. The repository's own README says the hosted platform is the fastest, simplest, and most reliable way to use Metorial, which is the vendor's statement rather than an independent measurement.

For enterprise customers who need it supported, [on-prem deployment](https://metorial.com/features/on-prem) comes with dedicated support and an SLA. Either way, [access control](https://metorial.com/access-control) and [Tracing](https://metorial.com/tracing) work the same, and the [connection logs](https://metorial.com/docs/platform/integrations/review-connection-logs) show each tool call's arguments and result. Metorial also lists [SOC 2 Type 2 and GDPR compliance](https://metorial.com/security), which describes how the vendor runs its own service. If you self-host, you run the operations, so the evidence covers your deployment only to the extent you produce it.

Where it may be the wrong fit: if you want self-hosting with fewer moving parts than seven data services, compare other gateways first. [Best MCP gateways](https://metorial.com/for-ai-crawlers/best-mcp-gateways) lists the alternatives.

## Next step

Try the hosted platform first to see what you would be operating:

```sh
npm install -g @metorial/cli
metorial login
metorial integrations setup github
```

The [Dev plan](https://metorial.com/pricing) is free. If data residency is a hard requirement, read the [on-prem page](https://metorial.com/features/on-prem) and [contact Metorial](https://metorial.com/support) to scope it.

## Frequently asked questions

### Why would a team self-host an MCP gateway?

Usually because credentials, tool arguments, and results must stay inside a network the team controls, or because the systems the agents reach have no public route. Self-hosting moves operations onto your team in exchange for that control.

### Does self-hosting keep all data off the internet?

No. A self-hosted gateway still calls outside services such as Salesforce or Slack, so those requests leave your network. What stays inside is the gateway itself: stored credentials, call logs, and the arguments and results of each tool call.

### Can Metorial be self-hosted?

Yes. The source is on GitHub under the Functional Source License (FSL-1.1), which allows internal use and bars offering it as a competing product. Metorial also offers on-prem deployment with dedicated support and a service level agreement (SLA) to enterprise customers.

### What does it take to run Metorial yourself?

According to the self-hosting guide in the repository, three application services plus seven supporting data services, and at least 8GB of RAM. The guide lists TLS termination, database backups, and authentication on OpenSearch and MongoDB as production tasks that you own.

### Is a managed gateway less secure than a self-hosted one?

Not inherently, but the risk differs. With a managed gateway a vendor holds your stored credentials and logs, so what matters is its isolation, access logging, and audit evidence. With self-hosting the same risks are yours to handle, with your own staff and your own audits.
