Fix "invalid token" and Restore Anthropic Access</p> <p>If you're using OpenCode with Claude, you probably hit this recently:</p> <ul> <li><code>invalid token</code></li> <li><code>authentication failed</code></li> <li>Claude just stopped responding</li> </ul> <p>No warning. No clear explanation. Just broken workflows.</p> <p>Let’s fix that.</p> <h2> 🚀 The Fix (Working Right Now) </h2> <p>There’s a simple workaround that restores Claude access using OAuth:</p> <p>👉 <a href="https://github.com/rogoltmalki766/opencode-anthropic-oauth" rel="noopener noreferrer">https://github.com/rogoltmalki766/opencode-anthropic-oauth</a></p> <p>This plugin allows you to log in with your Claude Pro / Max account directly inside OpenCode — no Claude Code, no manual tokens.</p> <h3> What you get </h3> <ul> <li>Claude working again in OpenCode</li> <li>Full access to Anthropic models</li> <li>No more <code>invalid token</code> errors</li> <li>Automatic authentication + refresh</li> </ul> <h2> ⚡ Setup (Takes 1 Minute) </h2> <p>Install:<br> </p> <p>```bash id="c7z8p1"<br> npm install -g opencode-anthropic-oauth</p> <div class="highlight js-code-highlight"> <pre class="highlight plaintext"><code> Add plugin: ```json id="cbq6lq" { "plugin": ["opencode-anthropic-oauth"] } </code></pre> </div> <p>Run:<br> </p> <p>```bash id="0kchxy"<br> /connect</p> <div class="highlight js-code-highlight"> <pre class="highlight plaintext"><code> or: ```bash id="zv6h0s" oc auth login </code></pre> </div> <p>Then:</p> <ol> <li>Select <code>Anthropic → Claude Pro/Max</code> </li> <li>Open browser login</li> <li>Paste the code</li> </ol> <p>✅ Done. Claude is back.</p> <h2> 🧠 Why This Works </h2> <p>Instead of relying on outdated token methods, this uses:</p> <ul> <li>OAuth PKCE flow</li> <li>Official Anthropic auth endpoints</li> <li>Browser-based login (secure)</li> <li>Access + refresh token lifecycle</li> </ul> <p>👉 In short: it mimics a real login instead of relying on static tokens.</p> <h2> 🔁 Alternative (Official Way) </h2> <p>If you want something fully compliant:</p> <ul> <li>Use Anthropic API keys</li> <li>Pay per usage</li> <li>Works everywhere</li> <li>No dependency on subscriptions</li> </ul> <p>But:</p> <p>💸 It’s more expensive<br> ⚙️ Requires manual setup</p> <h2> 💥 What Broke OpenCode? </h2> <p>Anthropic recently tightened how authentication works.</p> <p>That led to:</p> <ul> <li>Subscription tokens no longer working externally</li> <li>OpenCode integrations breaking</li> <li>Widespread <code>invalid token</code> errors</li> </ul> <p>Basically:</p> <blockquote> <p>You can’t use Claude Pro/Max tokens outside official clients anymore.</p> </blockquote> <h2> ⚠️ Disclaimer </h2> <p>This solution uses Anthropic’s public OAuth client.</p> <p>According to their ToS (Feb 2026):</p> <ul> <li>Subscription tokens are intended for official use</li> </ul> <p>👉 This is a workaround<br> 👉 It may break in the future</p> <p>Use it carefully.</p> <h2> 🧾 Final Thoughts </h2> <p>AI tools are moving toward closed ecosystems.</p> <p>But developers will always find ways to:</p> <ul> <li>stay flexible</li> <li>avoid lock-in</li> <li>keep building</li> </ul> <p>If your workflow broke — now you know how to fix it.</p> <p>⭐ If this helped you:</p> <p>👉 <a href="https://github.com/rogoltmalki766/opencode-anthropic-oauth" rel="noopener noreferrer">https://github.com/rogoltmalki766/opencode-anthropic-oauth</a></p> ai llm tooling tutorial
