# Gemini's Managed Agents Can Now Run in the Background and Reach Your MCP Servers

> Google shipped four changes to Gemini API Managed Agents on July 7 — background execution, remote MCP, custom function calling, and credential refresh. The quiet one is the load-bearing one.

## Key takeaways

- On July 7 Google added four capabilities to Managed Agents in the Gemini API — a `background: true` flag that runs a task asynchronously on Google's servers, remote MCP so the agent reaches your tools from inside the cloud sandbox, custom function calling alongside MCP, and credential refresh across a long session — and it's on the free tier.
- Background execution is the one that changes your architecture: you stop holding an HTTP connection open for a ten-minute agent run and start polling or subscribing for completion, which is the difference between a task that survives a dropped connection and one that dies with it.
- Remote MCP moves the "where does my agent run" decision — a managed runtime can now reach your issue tracker, database, or browser service without a tunnel, which narrows the case for self-hosting to latency, data residency, and cost control.

## At a glance

| Concern | Before July 7 | After July 7 |
| --- | --- | --- |
| Long task | Hold an HTTP connection open for the whole run | `background: true` — start, then poll or subscribe for the result |
| Your own tools | Reachable only from where you ran the agent | Remote MCP — the cloud agent connects to your MCP server directly |
| Mixing tools | MCP or product functions, awkwardly | Custom function calling + MCP in one interaction |
| Long sessions | Credentials expire, agent stalls, user restarts | Scoped credentials refresh across interactions |
| Cost to try | — | Free tier |

## By the numbers

- **4** — new Managed Agents capabilities shipped July 7
- **background:true** — the flag that runs a task async on Google's servers
- **Free** — tier the features launched on, per Google's dev lead
- **0** — tunnels needed for a managed agent to reach a remote MCP server

Google shipped four changes to Managed Agents in the Gemini API on July 7, and the release note reads like a maintenance list: background execution, remote [MCP servers](/topics/mcp), custom [function calling](/topics/agent-frameworks), credential refresh. Three of those are conveniences. One of them quietly changes how you're supposed to build a long-running agent — and it's on the free tier, so the change reaches you whether or not you were planning an upgrade.
Here is the whole release in one screen, then why the boring-sounding one matters most.
What actually shipped
- **Background execution.** A new `background: true` parameter runs an interaction asynchronously on Google's servers. You start the task, get a handle, and then *poll or subscribe* for progress instead of holding a connection open until it finishes.
- **Remote MCP servers.** A Managed Agent running inside Google's sandbox can now reach an MCP server you host — docs, an issue tracker, a database, a browser service — without a tunnel or custom middleware.
- **Custom function calling.** Typed, product-specific functions can run alongside MCP tools in the same interaction, so you're no longer choosing one or the other.
- **Credential refresh.** An agent that runs across a long session can renew scoped credentials without asking the user to restart.

The one that changes your architecture
The other three are quality-of-life. Background execution is the one that moves a line on your diagram.
Until now, a Gemini agent task that took ten minutes needed a connection held open for ten minutes. That's fine on a demo and a liability in production: a dropped Wi-Fi connection, a server redeploy, a load balancer's idle timeout, or a closed laptop lid kills the run, and you're left reconstructing where it got to. Everyone building serious agents already worked around this with their own queues.
`background: true` folds that pattern into the API. You start the task, you get a handle, and completion arrives by polling or a subscription. The agent's work is now decoupled from the caller's connection.
> Background execution isn't a feature so much as a demotion of the HTTP request from "the thing that holds your task" to "the thing that kicked it off." That demotion is the entire difference between a demo agent and a production one.

If you've read our take on [triggering an agent — cron vs webhook vs queue](/posts/how-to-trigger-an-ai-agent-cron-vs-webhook-vs-queue.html), this is the same lesson arriving as a default: slow work belongs on a job model, not a synchronous call.
Remote MCP narrows the self-host case — it doesn't close it
The second-most-important change is remote MCP. The reason a lot of teams kept agents on their own infrastructure was reach: the agent needed to touch *your* systems, and a managed runtime in someone else's cloud couldn't get to them without a tunnel. Remote MCP removes that specific objection. A Gemini Managed Agent can now connect to the MCP servers you already run.
That reopens the [where-to-run-a-long-running-agent decision](/posts/2026-06-24-where-to-run-a-long-running-ai-agent.html) that a lot of founders thought they'd settled. But it reopens it, it doesn't decide it. Three reasons to self-host survive intact:
- **Latency.** An agent that makes twenty tool calls per task pays the round trip to your MCP server twenty times. If those tools live next to your agent, you save it; across clouds, you don't.
- **[Data residency](/topics/model-selection).** If the data can't leave your infrastructure for legal or compliance reasons, "the cloud agent can reach your tools" is not a feature — it's the problem.
- **Cost and concurrency control.** A managed runtime is convenient until you're running thousands of concurrent agents and want to own the bill and the backpressure.

What to do about it
If you're on Gemini and you've been holding connections open for long agent runs, this is a free reliability upgrade — move to `background: true` and delete your homegrown keep-alive. If you self-host mainly because your agent needed to reach your own tools, re-run that decision now that remote MCP exists; you may be self-hosting for a reason that no longer applies. And if you self-host for latency, residency, or cost, none of that changed today — hold your ground.
The headline is four features. The story is that Google just made the *default* way to build a Gemini agent look a lot more like the way experienced teams were already building one by hand.

## FAQ

### What did Google add to Gemini Managed Agents?

Four things on July 7, 2026: background execution (a `background: true` parameter that runs an interaction asynchronously on the server so you poll or subscribe for the result), remote MCP server support (the agent connects to your MCP tools from inside Google's sandbox), custom function calling alongside MCP tools in the same interaction, and credential refresh so a long-running agent can renew scoped credentials without restarting the session.

### Why does background execution matter?

Because a long agent task no longer needs an open connection. You start the task, get a handle, and poll or subscribe for completion — so a dropped connection, a redeployed server, or a closed laptop lid doesn't kill the run. It moves long agent work from "request/response" to "job queue," which is how production systems already treat anything slow.

### What is remote MCP and why is it a big deal?

MCP (Model Context Protocol) is the standard way to expose tools to an agent. "Remote MCP" means the managed agent running in Google's cloud can reach an MCP server you host — a documentation system, issue tracker, database, or browser service — without a local tunnel or custom middleware. It removes a real reason teams kept agents on their own infrastructure.

### Do I need a paid plan?

No. Google's developer lead said Managed Agents, including these updates, are available on the free tier to start. You pay for model usage as you scale, but you can wire up background execution and remote MCP without a contract.

### When should I still self-host instead of using Managed Agents?

When latency to your tools matters more than convenience, when data residency or compliance forbids the data leaving your infrastructure, or when you need fine control over cost and concurrency. Remote MCP narrows the gap, but it doesn't close these three.
