Next-Generation Unified AI Agent SaaS Connector & Multi-Provider Gateway
Connect AI agents to 1,000+ SaaS platforms, vector databases, and 500+ LLM models via standard Model Context Protocol (MCP), REST API, and CLI interfaces. Built for high resilience, zero-trust security, and real-time metering.
π Key Features
- Universal MCP & REST Connector Bridge: Native bidirectional translation between MCP tool definitions (
listMcpTools), OpenAPI specs, and HTTP endpoints. - Multi-Provider LLM Router & Circuit Breaker: Intelligent request dispatching across AI providers (OpenAI, Anthropic, Gemini, Groq, Ollama) with latency-based auto-failover, exponential retry, and circuit breaker protection (
lib/router.js). - Zero-Trust Encrypted Credential Vault: AES-256-CBC encrypted credential manager supporting granular agent scope permissions, token rotation, and immutable audit logs (
lib/vault.js). - Sliding-Window Rate Limiter & Token Metering Engine: Precision sliding-window rate limiting and per-agent token usage tracking for prompt/completion metering (
lib/metering.js). - Interactive Browser Playground Studio: Single-file visual dashboard (
demo/index.html) featuring live MCP tool registry, route inspector, and real-time circuit state telemetry. - Strict Automated Quality Gate: Comprehensive inspection engine auditing tool schema completeness, encryption status, rate limiting rules, and circuit breaker health (
lib/qualityGate.js). - Checkpointed Auto-Installer: Includes executable
./install.sh --resumescript for error recovery during setup.
