Amp CLI sends 'context-1m-2025-08-07' in Anthropic-Beta header which
requires a special 1M context window subscription. After upstream rebase
to v6.3.7 (commit 38cfbac), CLIProxyAPI now respects client-provided
Anthropic-Beta headers instead of always using defaults.
When users configure local OAuth providers (Claude, etc), requests bypass
the ampcode.com proxy and use their own API subscriptions. These personal
subscriptions typically don't include the 1M context beta feature, causing
'long context beta not available' errors.
Changes:
- Add filterBetaFeatures() helper to strip specific beta features
- Filter context-1m-2025-08-07 in fallback handler when using local providers
- Preserve full headers when proxying to ampcode.com (paid users get all features)
- Add 7 test cases covering all edge cases
This fix is isolated to the Amp module and only affects the local provider
path. Users proxying through ampcode.com are unaffected and receive full
1M context support as part of their paid service.
CLI Proxy API
🔔 Important: Amp CLI Support Fork
This is a specialized fork of router-for-me/CLIProxyAPI that adds support for the Amp CLI tool.
Why This Fork Exists
The Amp CLI requires custom routing patterns to function properly. The upstream CLIProxyAPI project maintainers opted not to merge Amp-specific routing support into the main codebase.
Which Version Should You Use?
- Use this fork if you want to run both Factory CLI and Amp CLI with the same proxy server
- Use upstream (router-for-me/CLIProxyAPI) if you only need Factory CLI support
📖 Complete Setup Guide
→ USING_WITH_FACTORY_AND_AMP.md - Comprehensive guide for using this proxy with both Factory CLI (Droid) and Amp CLI and IDE extensions, including OAuth setup, configuration examples, and troubleshooting.
Key Differences
This fork includes:
- ✅ Amp CLI route aliases (
/api/provider/{provider}/v1...) - ✅ Amp upstream proxy support for OAuth and management routes
- ✅ Automatic gzip decompression for Amp upstream responses
- ✅ Smart secret management with precedence: config > env > file
- ✅ All Factory CLI features from upstream (fully compatible)
All Amp-specific code is isolated in the internal/api/modules/amp module, making it easy to sync upstream changes with minimal conflicts.

A proxy server that provides OpenAI/Gemini/Claude/Codex compatible API interfaces for CLI.
It now also supports OpenAI Codex (GPT models) and Claude Code via OAuth.
So you can use local or multi-account CLI access with OpenAI(include Responses)/Gemini/Claude-compatible clients and SDKs.
