klava

README file written by hands primarily

Klava is a CLI tool for using code agents with any provider. Use Claude Code with your OpenAI-compatible provider. Make code agents more secure by filtering out leaked secret keys and cryptographic keys from your filesystem.

Features

• Fast & Lightweight: Written in Rust with async I/O
• Universal: Works with any OpenAI-compatible API (OpenRouter, Qwen, Cloud.ru, local LLMs)
• Security Guardrails: Filters out leaked secret keys and cryptographic keys from your filesystem before sending requests to LLM APIs

Installation

You can install klava from pip, cargo, mise!

pip install klava
cargo install klava --locked
mise use -g cargo:klava

Or you can build klava from source. You need to install rustup, clone the repository and then

cargo install --path . --locked

Launch AI Code Agent

The launch command starts the proxy server and launches an AI code agent with appropriate environment variables:

klava launch
klava launch claude
klava launch claude --provider qwen
klava launch opencode

Notice: When launching opencode, you need to manually select the "klava" model using the model command in opencode after it starts.

Supported code agents:

Configuration File Location

To find the config file path on your system, run:

klava config

Platform-specific config file locations:

• Linux: ~/.config/klava/config.toml
• macOS: ~/Library/Application Support/klava/config.toml
• Windows: %APPDATA%\klava\config.toml

Config file

port = 48017
verbose = false
active_provider = "qwen"

[[providers]]
name = "qwen"
type = "qwen-code"

[[providers]]
name = "cloudru"
type = "openai-compatible"
base_url = "https://foundation-models.api.cloud.ru"
api_key_name = "CLOUD_RU_KEY"
reasoning_model = "zai-org/GLM-4.7"
completion_model = "zai-org/GLM-4.7"

[[providers]]
name = "openrouter"
type = "openai-compatible"
base_url = "https://openrouter.ai/api"
api_key_name = "OPENROUTER_API_KEY"
reasoning_model = "z-ai/glm-5.1"
completion_model = "z-ai/glm-5.1"

Notice: base_url should not include /v1 at the end!

Notice: You can use api_key_name if you have the api_key in your environment, if you want you can set api_key in the toml file with the api_key variable.

Notice: The type can be openai-compatible or qwen-code. qwen-code uses an authentication flow involving reverse engineering of the Qwen Code application. You can use 1000 free requests per day of the great large model, but with risks due to this being an unofficial implementation of qwen-code.

Manual Claude Execution

If you run klava up, and you want to run claude manually use this command

ANTHROPIC_BASE_URL=http://localhost:48017 claude

Don't forget to change the port to your klava proxy server port.

View Proxy Logs

View or follow proxy server logs:

klava logs          # View recent logs
klava logs -f       # Follow logs (like tail -f)
klava logs --follow # Follow logs (long form)

Note: The -v flag works only with the klava up command to enable verbose logging. When used with klava logs, it doesn't change the output. To see verbose logs, start the server with klava up -v first, then view the logs.

Known Limitations

The following Anthropic API features are not supported currently (Claude Code and similar tools work without these parameters): Many features like images are not ready yet... It's a work-in-progress tool.

Troubleshooting & Known Pitfalls

• ❌ Wrong: https://openrouter.ai/api/v1
• ✅ Correct: https://openrouter.ai/api
• The proxy automatically adds /v1/chat/completions

Roadmap & Contributing

Contributions welcome!

Current vision is:

• Refactoring -> split codebase into many crates like proxy, cli, providers ...)
• Add more Guardrails
• Add Token optimization algorithms. Reduce cost is a crucial goal
• Creating extensions mechanism as first class citizen.
• Add more providers and agents
• Add benchmark wars between agents
• Add remote hand control using Telegram and Mobile
