euron-coding-agent 1.0.4

Lightweight provider-agnostic agentic coding backend (CLI + server) for the Euron VS Code extension.

euron-coding-agent

The Python agent backend and standalone CLI behind the Euron Coding Agent VS Code extension. An open-source, model-agnostic agentic coding assistant that plans, edits code, runs commands, searches the web, reviews diffs, coordinates teams of sub-agents, and runs on cron schedules - with your approval at every step.

Provider-agnostic: works with Anthropic, OpenAI, Google Gemini, OpenRouter, Groq, Cerebras, DeepSeek, Together, Mistral, xAI, Vercel AI Gateway, Euron/Euri, Ollama, LM Studio, or any OpenAI-compatible / self-hosted endpoint.

Install

pip install euron-coding-agent
euron-agent update                            # update to the latest anytime
# optional extras:
pip install "euron-coding-agent[anthropic]"   # native Anthropic client
pip install "euron-coding-agent[mcp]"         # Model Context Protocol servers

Tip: install into a virtual environment for isolation. The client auto-adapts to each provider's API (e.g. models needing max_completion_tokens instead of max_tokens, or rejecting a custom temperature) - no model-specific config needed.

Quick start (CLI)

euron-agent                                    # interactive chat in the current folder
euron-agent run "add a /health route to app.py"
euron-agent run "summarize the repo" --json     # headless JSON output for CI/scripts
euron-agent serve --host 0.0.0.0 --port 8000    # self-host with bearer-token auth

Set a provider and key right inside the chat (no files needed):

you: /provider openai      # or gemini, anthropic, groq, ollama, ...
you: /key                  # paste your API key (stored in ~/.euron-agent)
you: create a FastAPI hello-world app with a test

Or use environment variables (OPENAI_API_KEY, ANTHROPIC_API_KEY, GEMINI_API_KEY, EURI_API_KEY, ...) or a config.yaml. Built-in provider profiles mean no config file is required - just pick a provider and supply a key.

CLI commands

euron-agent                     interactive chat (remembers provider/key)
euron-agent run "<task>"        one-shot task ( --yes to auto-approve, --json headless )
euron-agent providers           list configured providers
euron-agent init                scaffold config.yaml + .env
euron-agent serve               run the API / WebSocket server ( --port 0 = auto )
euron-agent --team-name <name> "<task>"   multi-agent team (coordinator + specialists)
euron-agent team                list multi-agent teams
euron-agent schedule create "<name>" --cron "0 9 * * MON-FRI" --prompt "<task>"
euron-agent schedule list | run <id> | remove <id> | daemon
euron-agent plugin add <dir|zip-url> | list | remove <name>
euron-agent sessions            list saved sessions (dashboard)
euron-agent chat --session <id> | --resume   resume a past session

In-chat commands: /provider /key /model /effort /plan /review /compact /init /skills /search /usage /undo /reset /yes /help /exit, plus any custom command in .euron/commands/.

Features

• Agentic tool-calling loop: plan, read, search, edit, run, verify.
• 28 sandboxed tools: read/write/edit/multi_edit/create/delete files, glob, search, run_command (streaming), background processes, git status/diff/commit/ branch/push, open_pr, git worktrees, web_search, web_fetch.
• Plan mode, sub-agents, and multi-agent teams with persistent state.
• Scheduled agents on cron schedules (independent of any terminal).
• MCP servers, plugins, skills, project memory (AGENTS.md), and custom commands.
• Permissions (allow/ask/deny), hooks, approvals with diffs, checkpoints, undo.
• Web search/fetch, multimodal image input, token and cost tracking, extended thinking, model fallback chains.
• Messaging notifications: Slack, Discord, Telegram, Google Chat, WhatsApp, Linear.
• Headless JSON mode and a self-hostable server with bearer-token auth.

Server

• GET /health liveness.
• GET /providers configured providers.
• POST /agent/run one-shot, non-interactive (set "auto_approve": true).
• WS /ws streaming agent with per-action approval (used by the extension).

The WebSocket init message accepts provider, model, api_key, and base_url so secrets never need to live on disk. Set EURON_AGENT_TOKEN (or serve --token) to require bearer auth.
