Vue d'ensemble

Arc Relay is a management proxy for Model Context Protocol (MCP) servers. It sits between your AI tools (Claude Code, Claude Desktop, Cursor, etc.) and your MCP servers, providing a single authenticated endpoint that handles Docker container lifecycle, health monitoring, OAuth flows, access control, and multi-transport proxying. Manage all your MCP servers from one web UI. (Formerly MCP Wrangler)

Cible: /var/run/docker.sock
Défaut: /var/run/docker.sock
Valeur: /var/run/docker.sock

Encryption KeyVariable

Encrypts stored credentials (OAuth tokens, API keys, env vars). Generate with: openssl rand -hex 32. IMPORTANT: Do not lose this key - encrypted data becomes unreadable without it. Upgrading from MCP Wrangler? Use the same key as before.

Cible: ARC_RELAY_ENCRYPTION_KEY

Session SecretVariable

Signs web UI session cookies. Generate with: openssl rand -hex 32. If omitted, a random secret is generated on each restart (sessions won't survive restarts).

Cible: ARC_RELAY_SESSION_SECRET

Admin PasswordVariable

Password for the admin web UI account (only used on first run to create the admin user).

Cible: ARC_RELAY_ADMIN_PASSWORD

Database PathVariable

Path to SQLite database inside the container. Upgrading from MCP Wrangler? Set to /data/mcp-wrangler.db or rename your DB file.

Cible: ARC_RELAY_DB_PATH
Défaut: /data/arc-relay.db
Valeur: /data/arc-relay.db

Base URLVariable

Cible: ARC_RELAY_BASE_URL

Sentry DSNVariable

Sentry DSN for error tracking. Leave blank to disable.

Cible: ARC_RELAY_SENTRY_DSN

LLM API KeyVariable

Anthropic API key for LLM-powered tool context optimization. Enables the 'Run Optimization' feature on server detail pages to compress tool descriptions and reduce token usage. Get a key at https://console.anthropic.com/. Leave blank to disable.

Cible: ARC_RELAY_LLM_API_KEY

LLM ModelVariable

Model to use for tool optimization. Default is claude-haiku-4-5-20251001 (fast and cheap). Only change if you want to use a different Anthropic model.

Cible: ARC_RELAY_LLM_MODEL
Défaut: claude-haiku-4-5-20251001
