Preface
Claude Code is a command-line coding assistant that can read project files, explain unfamiliar code, generate patches, run development tasks, and help developers work through complex repositories. Its usefulness depends on more than the command itself, however. The client may need to reach several services for authentication, model requests, package downloads, update checks, and documentation access. If those connections are unstable, users may see repeated sign-in prompts, timeout messages, incomplete responses, or failed installation commands.
Clash Verge can make this environment easier to manage. It does not provide an internet connection or proxy subscription by itself. Instead, it acts as a local traffic controller: you import a subscription supplied by a proxy provider, select a usable node, and decide which applications or domains should use the proxy. This separation is important because a well-configured Clash client cannot compensate for an expired subscription, an overloaded node, or a provider that does not support the traffic you need.
This guide explains a practical 2026 setup for using Claude Code with Clash Verge on a desktop computer. It focuses on subscription import, system proxy behavior, TUN mode, routing choices, DNS considerations, and troubleshooting. The goal is not to force every connection through a distant server. The goal is to create a predictable setup in which Claude Code can authenticate and send coding requests while ordinary local traffic continues to use the most suitable route.
Technical Goal
Build a stable, easy-to-debug proxy environment for Claude Code without unnecessarily routing local services, private repositories, or unrelated traffic through the proxy.
1How Claude Code and Clash Verge Work Together
Before changing settings, it helps to understand the connection chain. Claude Code runs locally in your terminal, but its requests are sent to remote services. Your operating system then decides whether those requests should use a system proxy. Clash Verge listens on local proxy ports and forwards matching traffic to the selected remote node. The full path is usually:
- Claude Code or a related command creates a network request.
- The operating system or application checks its proxy environment.
- Clash Verge receives the request on an HTTP, HTTPS, or SOCKS port.
- The active Clash rule determines whether the request is sent to
PROXYorDIRECT. - The selected proxy node connects to the destination and returns the response to the terminal.
In a simple browser test, enabling the system proxy may be enough. Command-line tools are less consistent. Some programs read operating-system proxy settings, while others only read environment variables such as HTTP_PROXY, HTTPS_PROXY, and ALL_PROXY. A command can therefore work in a browser while failing in the terminal, or work in one shell but not another.
There are also several independent connection stages. The initial account sign-in may open a browser page, while the actual coding request is made by the command-line process. Package installation may use a registry domain that is unrelated to the model service. Treating all these steps as one connection can make troubleshooting confusing.
Key Principle
Test authentication, model requests, package downloads, and ordinary web access separately. A successful browser sign-in does not automatically prove that the terminal can reach every required endpoint.
2Prepare Clash Verge and Import a Subscription
Install Clash Verge from a trustworthy source and choose the build that matches your operating system. The exact interface may vary between Clash Verge releases and related clients such as Clash Verge Rev, but the workflow remains similar: add a profile, update it, select it, and activate a proxy group.
- Open the Clash Download Page and install the appropriate desktop client for Windows, macOS, or Linux.
- Obtain a valid subscription URL from your proxy provider. Do not paste a random URL from an untrusted website, because subscription links can expose account information or load unsafe configuration rules.
- Open the Profiles or Subscriptions page in Clash Verge and paste the URL into the subscription field.
- Click the update or download button, wait for the profile to finish loading, and select the new profile as active.
- Open the Proxies page and choose a policy group, then select a node with a reasonable latency and a location appropriate for the service.
A profile is more than a list of servers. It may include proxy groups, DNS settings, rule providers, and automatic update intervals. If the profile imports successfully but the Proxies page contains no usable nodes, the provider may have returned an invalid configuration or the subscription may have expired. Check the profile's last update time and inspect any error message before modifying the YAML file.
Choosing a Usable Node
For Claude Code, the fastest node is not always the most reliable one. A node with slightly higher latency may produce more consistent long responses than a heavily shared node that periodically resets connections. Test at least two or three nodes and pay attention to:
- Latency: Lower ping usually improves sign-in and initial response time, but it does not measure long-term stability.
- Packet loss: Intermittent loss can cause retries, truncated output, or broken package downloads.
- IP reputation: Some shared or datacenter addresses may be challenged or refused by online services.
- Protocol support: Confirm that the selected node and the Mihomo core support the protocol defined by the profile.
- Usage limits: A provider may slow or suspend a node after bandwidth or connection quotas are reached.
3Select the Right Mode for Command-Line Traffic
Clash Verge generally offers several operating modes. The names differ slightly by client, but the concepts are familiar. Rule mode follows the profile's routing rules, Global mode sends most traffic through the selected proxy group, and Direct mode bypasses the proxy. For a first Claude Code test, Rule mode is normally the best starting point because it preserves the profile's intended behavior while allowing targeted routing.
| Mode | Best use | Important limitation |
|---|---|---|
| Rule | Daily use and split tunneling | Depends on the quality and completeness of the profile rules |
| Global | Short diagnostic tests when a destination is not matched correctly | May route local services, package registries, and private resources unnecessarily |
| Direct | Confirming whether a service works without the proxy | Will not help when the local route cannot reach the required service |
Enable the System Proxy option if you want applications that honor system proxy settings to use Clash automatically. This is often enough for a browser-based sign-in flow. It does not guarantee that every terminal program will follow the setting. If Claude Code still reports a connection failure, configure the shell environment explicitly or use TUN mode.
System Proxy or TUN Mode?
System proxy mode is easier to understand and usually creates fewer side effects. It is a good choice when the command-line tool supports HTTP or HTTPS proxies and you want to keep control visible. TUN mode creates a virtual network interface and captures a broader range of traffic, including applications that ignore system proxy variables. It may be useful for DNS handling, authentication helpers, or tools that use connections outside the traditional proxy settings.
TUN mode requires extra permissions and can conflict with another VPN, security application, virtual machine network, or corporate endpoint policy. Start with System Proxy mode. Enable TUN only when you have identified a real compatibility problem, and turn off other tunnel applications before testing.
Do Not Change Everything at Once
Record the current mode, node, and DNS settings before troubleshooting. Switching mode, profile, node, and shell variables simultaneously makes it difficult to discover which change fixed or caused the problem.
4Configure the Terminal Environment
If the terminal does not inherit the Clash system proxy, set temporary environment variables for the current session. First identify the local HTTP or mixed port shown in Clash Verge. Common ports include 7890 or another value chosen by the active profile. Use the port displayed by your client rather than copying an example blindly.
These variables affect processes launched from that terminal window. They do not permanently modify your operating system and disappear when the session closes. This makes them useful for testing. If the test succeeds, you can decide whether to add equivalent settings to your shell profile, configure a package manager separately, or continue using the system proxy.
Some tools use lowercase variable names, while others check both cases. If a command ignores the uppercase values, try setting the lowercase versions as well. Avoid placing a proxy password directly in a shared shell configuration file, because command history and dotfiles may be backed up or uploaded.
Test the Local Proxy Before Testing Claude Code
Verify that the local port is listening and that the request is actually going through Clash. A basic test can use curl:
Then inspect the Clash connection panel. You should see the request appear in the connection list. If the command succeeds but no connection is shown, the terminal may be using a different proxy, a cached route, or a direct connection. If the request fails and Clash shows no record, check the port, environment variables, and local firewall first.
5Build a Predictable Routing Strategy
Rule mode is most useful when you understand what should be proxied and what should remain direct. Claude Code may contact different domains for account authentication, API requests, package metadata, source control, and documentation. Domain names and service endpoints can change, so avoid relying on an old list copied from an unrelated configuration. Use the Clash connection log to observe the actual destinations generated by your installation.
A practical strategy is to begin with a narrow test. Keep Rule mode active, launch the sign-in process, and watch which connections are accepted, rejected, or sent DIRECT. If a required destination is incorrectly routed, add a narrowly scoped rule through the profile's supported override mechanism rather than editing the downloaded subscription permanently.
The domains above are placeholders, not a universal Claude Code rule list. Your provider's profile may already include appropriate rules, and service endpoints can change. Do not route an entire country-code domain or every cloud provider domain through the proxy merely because one required request failed. Broad rules can slow development tools and may send private repository traffic to a third party.
| Traffic type | Typical starting choice | Reason |
|---|---|---|
| Authentication and model requests | PROXY when the direct route is unavailable | These requests require a reachable and consistent service path |
| Public package registries | Test DIRECT and PROXY separately | The faster path depends on regional routing and registry availability |
| Private Git servers and company tools | DIRECT or corporate-approved route | Private traffic may require internal DNS and access controls |
| Operating-system updates | Follow your organization's policy | Proxying updates may conflict with certificate inspection or security rules |
6DNS, Credentials, and Safe Usage
DNS determines how domain names are resolved. If the local resolver returns an incorrect result while the proxy handles the later connection, the request can still fail. Mihomo-based clients often provide enhanced DNS modes such as fake-ip and redir-host. The best choice depends on your operating system, local network, and the compatibility of applications you use.
For a normal desktop setup, begin with the DNS settings supplied by the profile. Change them only when the connection log, DNS errors, or repeated domain-resolution failures indicate a problem. A common diagnostic approach is to compare a request in Direct mode with the same request in Proxy mode, then inspect whether the resolved address and route change as expected.
Never paste API keys, access tokens, private source code, or sensitive configuration files into a public troubleshooting forum. Claude Code may read files in the working directory and may include relevant content in a request when you approve an operation. Review project instructions, environment variables, and terminal output before sharing screenshots or logs. Clash itself also stores profiles and connection metadata locally, so protect the profile directory if it contains provider credentials.
Security Reminder
A proxy changes the network path; it does not make untrusted software safe. Use official installers, keep credentials out of shell history, and choose a provider you trust with your traffic.
7Simple Troubleshooting Workflow
When Claude Code cannot connect, avoid repeatedly restarting every application. Follow a fixed sequence so that each layer can be verified independently.
- Check the subscription: Confirm that the profile updated successfully and that it contains active nodes.
- Check the selected node: Test another node in the same group. A single failed node does not prove that the configuration is wrong.
- Check Clash mode: Use Rule mode first, then briefly test Global mode to determine whether a missing rule is involved.
- Check the local port: Confirm that the port in your terminal variables matches the port displayed by Clash Verge.
- Check the connection log: Look for rejected requests, DNS failures, connection resets, and destinations unexpectedly marked DIRECT.
- Check the shell: Print or inspect the proxy variables, then start a new terminal after changing them.
- Check competing network tools: Disable another VPN, proxy switcher, or security filter temporarily if permitted by your network policy.
- Test each stage: Verify a normal HTTPS request, complete browser authentication, and finally run a small Claude Code request.
| Symptom | Likely cause | First action |
|---|---|---|
| Browser sign-in works, terminal fails | Terminal does not inherit the system proxy | Set temporary proxy environment variables and retry |
| All requests time out | Bad node, expired subscription, or incorrect port | Update the profile, switch nodes, and verify the local port |
| Only one domain fails | Missing rule or DNS-specific problem | Inspect the connection log and test the domain in Global mode |
| Output stops halfway | Unstable node, packet loss, or long-connection timeout | Try a less congested node and check whether TUN or proxy mode is more compatible |
Once the problem is solved, remove temporary test settings that you no longer need. A forgotten global proxy variable can later affect Git, Docker, package managers, or internal company services in unexpected ways.
Frequently Asked Questions
Does Clash Verge include a proxy subscription?
No. Clash Verge is a client application. You must obtain a compatible subscription or server configuration separately. The client manages profiles and routes traffic, but it does not sell connectivity or guarantee access to any online service.
Should I keep Global mode enabled for Claude Code?
Usually not. Global mode is useful as a short diagnostic test, but Rule mode is safer for daily development because it avoids sending every local request through the proxy. If Global mode fixes the problem, inspect the connection log and create a narrow rule for the missing destination.
Do I need TUN mode?
Not necessarily. Start with System Proxy mode and terminal environment variables. Use TUN mode when a required helper or command ignores those settings, or when DNS and non-HTTP traffic must be captured. TUN mode needs extra permissions and may conflict with other network software.
What should I do when the profile update fails?
Verify the subscription URL, check whether the provider account has expired, and try updating from a different network if allowed. If the URL is valid but the imported file has no nodes, contact the provider rather than editing random fields in the downloaded configuration.
With a valid subscription, a tested node, a correctly selected mode, and a clear separation between system proxy and terminal settings, Clash Verge can provide a much more predictable environment for Claude Code. Keep the configuration narrow, monitor the connection log, and change one variable at a time when troubleshooting.
