# Mesh MCP Server Environment Configuration
# Copy this file to .env and fill in your values.
#
# Mesh uses a CLI-first architecture:
#   1. Gemini CLI (`gemini` on PATH) — direct subprocess calls
#   2. Codex CLI  (`codex`  on PATH) — direct subprocess calls
#   3. OpenRouter (HTTPS API)        — fallback for everything else
# At least one of these must be available.

# ===========================================
# OpenRouter (HTTP fallback)
# ===========================================

# Get your key from https://openrouter.ai/. Required if neither CLI is installed.
OPENROUTER_API_KEY=your_openrouter_api_key_here

# Optional: restrict which OpenRouter models are usable.
# Comma-separated, case-insensitive. Empty = no restriction.
# Examples:
#   OPENROUTER_ALLOWED_MODELS=opus,sonnet
#   OPENROUTER_ALLOWED_MODELS=google/gemini-2.5-pro,openai/o3
# OPENROUTER_ALLOWED_MODELS=

# ===========================================
# CLI binaries (optional path overrides)
# ===========================================

# By default Mesh searches PATH for `gemini` and `codex`. Override here if needed.
# GEMINI_CLI_PATH=/usr/local/bin/gemini
# CODEX_CLI_PATH=/usr/local/bin/codex

# Subprocess timeout in seconds (default 30).
# CLI_TIMEOUT_SECONDS=30

# ===========================================
# Defaults
# ===========================================

# Default model. 'auto' lets Mesh pick the best available model per task.
# Other examples: gemini-2.5-pro, gpt-5, o3, opus, sonnet
DEFAULT_MODEL=auto

# Default thinking depth for the thinkdeep tool. Only models that support
# extended thinking honor this; others ignore it.
# Options: minimal | low | medium | high | max
DEFAULT_THINKING_MODE_THINKDEEP=high

# ===========================================
# Conversation memory
# ===========================================

CONVERSATION_TIMEOUT_HOURS=24
MAX_CONVERSATION_TURNS=40

# ===========================================
# Logging
# ===========================================

# DEBUG | INFO | WARNING | ERROR
LOG_LEVEL=DEBUG
LOG_MAX_SIZE=10MB

# ===========================================
# Tool selection
# ===========================================

# Comma-separated list of tools to disable. Essential tools (version,
# listmodels) cannot be disabled. By default, non-essential tools are
# disabled to minimize context window usage.
DISABLED_TOOLS=analyze,refactor,testgen,secaudit,docgen,tracer

# ===========================================
# Locale (optional)
# ===========================================

# Force AI responses into a specific language. Empty = English default.
# Examples: fr-FR, en-US, zh-CN, ja-JP
# LOCALE=

# ===========================================
# Mesh internals
# ===========================================

# Force .env values to override system environment variables. Useful when
# multiple MCP clients pass conflicting environment vars; safe to leave
# false for production/CI deployments.
