GitHub Copilot for JetBrains now supports enterprise managed settings. In an August 18, 2026 changelog entry, GitHub said administrators can apply consistent controls for everyone on an enterprise Copilot plan—plugin governance, MCP server access, OpenTelemetry, and permission modes included. Read that as JetBrains catching up to Copilot’s shared governance file, not as a new policy language. The enterprise managed settings reference documents one `managed-settings.json` schema for Copilot clients, with a JetBrains IDEs column next to Copilot CLI, VS Code, the GitHub Copilot app, and the Copilot cloud agent. The changelog is blunt about the gap it is closing: the new MCP keys bring centrally managed MCP governance into JetBrains IDEs and prevent connections to servers outside the enterprise allowlist. ### MCP allowlists land in the JetBrains client Administrators can now use `allowedMcpServers` and `deniedMcpServers` to control which MCP servers developers may connect to from GitHub Copilot for JetBrains. The reference defines the pairing. `allowedMcpServers` is an allowlist of servers permitted to run; any server that does not match is blocked. Omit the key and all servers are allowed, subject to deny rules. `deniedMcpServers` entries are unconditionally blocked, even when they also match the allowlist. GitHub’s example configuration matches on `serverUrl`—including a GitHub Copilot API wildcard—or on `serverCommand`, such as an `npx` invocation of `@playwright/mcp@latest` or a `uvx` MarkItDown MCP. A deny example blocks `@modelcontextprotocol/server-filesystem` when it is launched against `/`. Those are the same keys the JetBrains announcement now says you can enforce from the center. `allowedMcpServers` and `deniedMcpServers` can be marked overridable in `managed-settings.json` with the `{ "overridable": }` syntax. Server-managed deployments can then give enterprise teams different allow and deny lists, falling back to the enterprise default when a team leaves a key unset. ### Plugins and marketplaces, locked from the center The changelog also adds enterprise-managed plugin governance inside JetBrains IDEs, with three settings: - **Enabled plugins.** `enabledPlugins` requires a plugin to be enabled or disabled. - **Additional marketplaces.** `extraKnownMarketplaces` makes approved plugin sources available. - **Restricted marketplaces.** `strictKnownMarketplaces` limits installation to approved sources. The reference fills in the shapes. Each `enabledPlugins` entry uses `PLUGIN-NAME@MARKETPLACE-NAME` as the key and a boolean value: `true` to require the plugin enabled, `false` to require it disabled. `extraKnownMarketplaces` is a map of named marketplace objects with a `source`. `strictKnownMarketplaces` is a list of marketplace objects; an empty array means complete lockdown. `extraKnownMarketplaces` supports only github (`OWNER/REPO`, optional ref/path), git (url), and directory (path). `strictKnownMarketplaces` is the longer list: github, git, url, npm, file, directory, hostPattern, and pathPattern. `enabledPlugins` and `extraKnownMarketplaces` are additive across enterprise and team files: the enterprise `managed-settings.json` sets a baseline, and a team file can add more plugins and marketplaces on top. Unlike the MCP keys, those two are not in the overridable list—they accumulate. ### Managed OpenTelemetry overrides the IDE Administrators can centrally configure OpenTelemetry for Copilot in JetBrains IDEs, including the collector endpoint, protocol, service name, resource attributes, and content-capture policy. Managed values take precedence over developer settings, so usage data is routed to the approved collector rather than whatever a local panel would have chosen. Developers are not left guessing. GitHub says they can review the applied configuration under **Settings > Tools > GitHub Copilot > Chat > OpenTelemetry**. The reference documents the `telemetry` object with `enabled`, `endpoint`, `protocol` (`http/json` or `http/protobuf`), `captureContent`, `lockCaptureContent`, `serviceName`, `resourceAttributes`, and HTTP `headers`. The JetBrains-specific claim in the changelog is narrower and operational: those managed values now win inside the IDE. ### A kill switch for Bypass Approvals and Autopilot The permission lock is `permissions.disableBypassPermissionsMode`. Set it to `disable` and the Copilot agent in JetBrains cannot use **Bypass Approvals** or **Autopilot**. That is the same key the reference describes as the bypass—or “YOLO”—kill switch. Bypass mode lets an agent run commands, access files, and fetch URLs without asking for approval. On Copilot CLI, `disable` suppresses `--yolo`, `--allow-all`, `--allow-all-tools`, `--allow-all-paths`, `--allow-all-urls`, and the `/yolo` and `/allow-all` slash commands. In VS Code it turns off `chat.tools.global.autoApprove` and keeps it off. In the GitHub Copilot app it blocks the “Allow all” setting for tool permissions. JetBrains now exposes the matching enterprise control under the Bypass Approvals and Autopilot names. The key is overridable by enterprise team mapping. Mark it `{ "overridable": "disable" }` in the enterprise file and a team file can set `"disableBypassPermissionsMode": "unmanaged"` so that team’s members are not bound by the enterprise default. ### Same file, same precedence This is not a JetBrains-only sidecar format. When several settings sources are present, the reference applies this order: MDM-managed settings, then server-managed settings, then file-based settings, then user-level settings. Earlier sources win. The reference calls out Copilot CLI’s `sandbox` key as an exception that combines toward the most restrictive setting. The August 18 JetBrains changelog does not mention `sandbox` or `remoteControl`, so treat those as unknown for this client until the reference or a later note says otherwise. GitHub’s try-it guidance is the latest GitHub Copilot plugin for JetBrains, plus the enterprise managed settings reference. Feedback can go through the in-product options, the Copilot IntelliJ feedback repository, or GitHub Community. If you already maintain `managed-settings.json` for other Copilot clients, open that file and confirm `allowedMcpServers`, `deniedMcpServers`, the plugin marketplace keys, `telemetry`, and `permissions.disableBypassPermissionsMode` match the policy you want on JetBrains. Then install the latest plugin so those IDEs stop being the unmanaged exception. ## Sources - [Enterprise managed settings in GitHub Copilot for JetBrains](https://github.blog/changelog/2026-08-18-enterprise-managed-settings-in-github-copilot-for-jetbrains/) - [Enterprise managed settings reference](https://docs.github.com/copilot/reference/enterprise-managed-settings-reference)
