77## How configuration propagates
88
9When the app starts a Code session, it translates your Claude Desktop on 3P [configuration keys](/docs/third-party/claude-desktop/configuration) into the equivalent Claude Code settings and passes them to the session. You configure one profile, and Cowork and Code both honor it.

1010
1111Each key reaches Claude Code through one of two mechanisms, and the distinction matters if you also deploy Claude Code's own managed settings (see [the next section](#interaction-with-claude-code%E2%80%99s-own-managed-settings)).

from line 23
2323| `disabledBuiltinTools` | Removes the listed tools from Code sessions. Tools your provider does not support, such as WebSearch on Amazon Bedrock, are removed automatically in addition to your list. |
2424| `builtinToolPolicy` | Tools set to `"ask"` require approval on each call in Code sessions, enforced via a PreToolUse hook and Claude Code `permissions.ask` rules. Argument-scoped rules such as `Bash(curl *)` are [applied as managed policy](#applied-as-managed-policy) instead. |
2525| `disableBypassPermissionsMode` | Removes bypass permissions mode. The app stops offering the mode and starts a session that requests it in a stricter permission mode instead, independent of Claude Code managed-settings precedence. The key requires Claude Desktop 1.46388.1 or later. A separately deployed Claude Code managed-settings file that sets `permissions.disableBypassPermissionsMode` to `"disable"` removes the mode as well. |
26| `skipWebFetchPreflight` | Turns off Claude Code's Web Fetch [domain check](/docs/third-party/claude-desktop/web-tools#web-fetch) against `api.anthropic.com`. A separately deployed Claude Code managed-settings file that sets `skipWebFetchPreflight` takes precedence. |
26| `skipWebFetchPreflight` | Turns off Claude Code's Web Fetch [domain check](/docs/third-party/claude-desktop/web-tools.md#web-fetch) against `api.anthropic.com`. A separately deployed Claude Code managed-settings file that sets `skipWebFetchPreflight` takes precedence. |
2727| `managedMcpServers` | Makes the same managed MCP servers available in Code sessions. The app handles the connection and authentication; the Code session sees only the resulting tool list. |
2828| `mcpToolTimeoutSec` | Applies your per-call MCP tool timeout to Code sessions as well, taking precedence over a user-set `MCP_TOOL_TIMEOUT`. |
2929| `organizationInstructions` | Appended to the Code session's system prompt after Claude Code's own. `CLAUDE.md` instructions still apply. |
30| `otlpEndpoint`, `otlpProtocol`, `otlpHeaders`, `otlpResourceAttributes` | Routes Claude Code's OpenTelemetry metrics and logs to your collector. See [Telemetry](/docs/third-party/claude-desktop/telemetry). |

3131| `disableEssentialTelemetry`, `disableNonessentialTelemetry` | Disables Claude Code's crash reporting and usage telemetry to Anthropic, mirroring Cowork. |
3232| `disableAutoUpdates` | The embedded Claude Code engine never self-updates regardless of this key; its version is managed by the app's own updater. |
3333| `inferenceMaxTokensPerWindow`, `inferenceTokenWindowHours` | The token budget is shared across Cowork and Code sessions and enforced before each turn. |
3434
35[`mcpPersistentAlwaysAllowEnabled`](/docs/third-party/claude-desktop/configuration#mcppersistentalwaysallowenabled) also applies to Code sessions. When it's `false`, the approval prompt for an MCP tool offers **Allow for this session** in place of **Always allow**, and the approval isn't saved to Claude Code's settings files. Allow rules already in those files, and hooks, keep allowing the tool until someone removes them. For scheduled tasks, see [Tool approvals on scheduled tasks](/docs/third-party/claude-desktop/configuration#tool-approvals-on-scheduled-tasks).

4141| Claude Desktop on 3P key | Claude Code policy it produces |
4242| - | - |
43| `coworkEgressAllowedHosts` | A network sandbox restricted to your hosts, `allowManagedDomainsOnly`, and `WebFetch` allow rules for the same hosts, which [don't block other hosts](/docs/third-party/claude-desktop/web-tools#how-the-egress-allowlist-applies-in-code-sessions). Claude Code's own inference and telemetry connections run outside the sandbox. A shell command or [HTTP hook](https://code.claude.com/docs/en/hooks#http-hook-fields) that calls your inference provider, `api.anthropic.com`, or your OTLP collector needs that host in the list. |

Claude Code's own inference and telemetry connections run outside the sandbox. A shell command or [HTTP hook](https://code.claude.com/docs/en/hooks#http-hook-fields) that calls your inference provider, `api.anthropic.com`, or your OTLP collector needs that host in the list. |
4444| `allowedWorkspaceFolders` | A filesystem sandbox for shell commands, which can then create or change files only inside your allowed roots and the session's temporary locations. The sandbox does not restrict which files those commands read unless you also set `blockReadsOutsideWorkingDirectories`. The roots are also passed as `additionalDirectories` at launch, which is always applied independent of managed-settings precedence, and the app keeps Claude's file tools inside the roots. The app also refuses to start a Code session outside an allowed root. |
4545| `blockReadsOutsideWorkingDirectories` | Claude Code's `permissions.blockReadsOutsideWorkingDirectories` for Code sessions. Claude's file tools refuse to read outside the working directories (the session's folder plus your allowed roots, if any) in every permission mode. Where the sandbox from `allowedWorkspaceFolders` or `coworkEgressAllowedHosts` is running, it also hides the user's home directory and similar locations, such as other users' home folders and mounted volumes, from shell commands, so a sandboxed command that reads there fails without a prompt. Without a running sandbox, a shell command that reads outside the working directories, or that Claude Code cannot analyze, asks the user for approval first, even in bypass permissions mode. The key requires Claude Desktop 1.46388.1 or later. The block takes effect only in sessions that run Claude Code v2.1.257 or later; if the app cannot install its current Claude Code engine and a session runs one older than v2.1.257 that is still on the device, that session runs without the block and the app logs a warning. |
4646| `managedMcpServers` | `strictPluginOnlyCustomization` set to `["mcp"]`, so the Code session does not load MCP servers that users define on Claude Code's side (`~/.claude.json`, a project's `.mcp.json`, or `claude mcp add`); your managed servers, which the app connects and supplies to the session itself, and MCP servers bundled in plugins still load. When [`isLocalDevMcpEnabled`](/docs/third-party/claude-desktop/configuration#islocaldevmcpenabled) is `false`, the app also sets an `allowedMcpServers` list that admits only remote servers, with `allowManagedMcpServersOnly`, so local (stdio) servers bundled in plugins from marketplaces or that users install themselves are refused, while those plugins' remote servers still connect. Per-tool `toolPolicy` values on each server are emitted as `permissions.deny` (for `blocked`) or `permissions.ask` (for `ask`) rules against the corresponding `mcp__<server>__<tool>` names. |
4747| `allowedPluginMcpServers` | `strictPluginOnlyCustomization` set to `["mcp"]` together with an `allowedMcpServers` list holding your entries and `allowManagedMcpServersOnly`, whether or not `managedMcpServers` is set. MCP servers bundled in plugins from marketplaces, or in plugins users install themselves, connect only when their URL matches an entry; no such plugin's local (stdio) server is admitted, and an empty list admits none. Your managed servers and the servers from the organization plugins directory still load. |
4848| `deniedPluginMcpServers` | The app sets a `deniedMcpServers` list holding your entries, whether or not `allowedPluginMcpServers` is set. When the key is unset or its list is empty, the app sets no `deniedMcpServers` list. When the value is not a list, or holds an entry that the app can't read, the app sets a list whose one entry is `*`, a pattern that matches every URL. See the [`deniedPluginMcpServers` reference](/docs/third-party/claude-desktop/configuration#deniedpluginmcpservers) for what the setting does and what an entry matches. |
49| `userPluginMarketplacesEnabled` | When `false`, a `strictKnownMarketplaces` allowlist. See [Controlling user extensions](/docs/third-party/claude-desktop/extensions#controlling-user-extensions) for what the key does. |
49| `userPluginMarketplacesEnabled` | When `false`, a `strictKnownMarketplaces` allowlist. See [Controlling user extensions](/docs/third-party/claude-desktop/extensions.md#controlling-user-extensions) for what the key does. |
5050| `builtinToolPolicy`, argument-scoped rules such as `Bash(curl *)` | A `permissions.ask` rule for each rule set to `"ask"`. |

52The network and filesystem sandboxes apply on macOS, and on Linux devices and [SSH hosts](/docs/third-party/claude-desktop/ssh-remote-sessions#managed-configuration-on-the-remote-host) with Claude Code's [sandbox dependencies](https://code.claude.com/docs/en/sandboxing) installed. Claude Code doesn't sandbox shell commands on Windows devices, and on a Linux device or SSH host without the dependencies commands run unsandboxed. In those cases, and when `coworkEgressAllowedHosts` contains `*` and `allowedWorkspaceFolders` is unset, `blockReadsOutsideWorkingDirectories` still confines Claude's file tools but can only ask the user to approve shell commands that read outside the working directories or that Claude Code can't verify. For what a remote session shows, see [Sandbox status on the remote host](/docs/third-party/claude-desktop/ssh-remote-sessions#sandbox-status-on-the-remote-host).

5454> [!WARNING]

56> Shell commands that run unsandboxed can reach hosts outside `coworkEgressAllowedHosts` and change files outside `allowedWorkspaceFolders`. Where the sandbox runs, a command that matches [`sandbox.excludedCommands`](https://code.claude.com/docs/en/sandboxing#run-commands-outside-the-sandbox-with-excludedcommands) in the user's own Claude Code settings also runs outside it, after Claude Code's regular permission flow. To keep Code off devices where the sandbox can't run, [turn off Code](#disabling-code) in the configuration you deploy to them. For SSH hosts, see [Sandbox status on the remote host](/docs/third-party/claude-desktop/ssh-remote-sessions#sandbox-status-on-the-remote-host).

5858Under `blockReadsOutsideWorkingDirectories`, sandboxed shell commands can still read system locations such as `/usr`, the session's plugin and attachment folders (which become read-only), and the user's git configuration files (`~/.gitconfig` and the `config`, `ignore`, and `attributes` files under `~/.config/git`), which can themselves hold credentials such as tokens in remote URLs. Other files under the home folder outside the working directories are hidden from them, including `~/.ssh`, stored git credentials, included git configuration files, signing keys, and the target of a symlinked git configuration file, so git operations that need those files fail in the session until the user re-opens the paths. In a local session Claude also cannot read a file attached or `@`-mentioned from outside the working directories, so users should move such files into the session's folder or an allowed folder first.

80> With the [Claude API](/docs/third-party/claude-desktop/claude-api) as the inference provider, Code sessions ask Anthropic for the server-managed settings of [the organization that owns the credential](https://code.claude.com/docs/en/server-managed-settings#platform-availability). This holds for an API key in your configuration, an API key from a credential helper, and **Sign in with Claude Console**.

While server-managed settings apply, Claude Code by default [ignores most keys](https://code.claude.com/docs/en/managed-settings#how-claude-code-combines-managed-sources) in a file or OS profile on the device, and a `"merge"` set there has no effect.

109A Code session can run its Claude Code engine on a remote host over SSH while the session's interface stays in Claude Desktop on the user's device. In a 3P deployment this is off until you set [`sshHostAllowlist`](/docs/third-party/claude-desktop/configuration#sshhostallowlist), because the app forwards the session's inference credential to the host. [SSH remote sessions](/docs/third-party/claude-desktop/ssh-remote-sessions) lists the credential kinds that work on a remote host and which of the keys above apply there.
