User-Level Access for Every Agent

Caylex ensures agents inherit the right permissions automatically, so they act with the same scope and trust level as their users.

What Is Agent Authorization?

Agent Authorization is an approach that allows agents to inherit exactly the permissions of the user they are working on. Instead of excessive access rights, agents are given clearly defined boundaries: what data they can read, what actions they can perform, and what systems they can work on.

Thanks to Caylex: Minimizes the risks of illegal actions and data leaks; Simplifies control over how agents interact with internal tools and workflows; Automatically manages the token cycle - from issuance to revocation, without manual intervention; Scalability - from a few agents to thousands in large organizations.

Why It Matters

Manual tool orchestration wastes time, drives up costs, and fails under scale — Caylex keeps workflows fast, efficient, and resilient.

Stop Wasting Tokens

Stop Wasting Tokens

Retries and wrong tools eat up compute. Caylex routes agents to the right tool faster, saving time and budget.

Build Reliable Agents

Build Reliable Agents

Accurate selection leads to fewer errors, better performance, and stable flows with consistent, trustworthy results.

Scale Without Friction

Scale Without Friction

Smart orchestration lets you grow your toolset without breaking workflows or sacrificing accuracy and speed.

Legacy Auth is Risky. Caylex Builds Trust.

Caylex intelligently customizes the tool interface to be highly relevant to your agent's workflows.

Convert large & complex APIs into a set of actions that intuitive for your agent to reason over.

The old way

  • Over-permissioning

  • Default admin creds

  • No scope auth

The Caylex way

  • One-time auth across deployments

  • Per-agent deployment scopes

  • Current user-aligned tokens

Secure by default, ready in seconds

Caylex replaces this with zero-trust, per-agent authorization that’s scoped, aligned to the invoking service, and secure by default. Setup is fast, safe, and purpose-built for modern deployments.

    Reliability & Error Recovery

    97% first-retry success. Caylex is detecting failures in real time, finding the cause, and retrying with the best fix — automatically.

    • Historical-aware retries

      Learns from past failures to select the most likely recovery path.

    • Graceful error recovery

      Provides the necessary context to quickly correct any errors.

    • Fallback tools

      Automatically switches to an alternative if the primary is unavailable.

    • Zero-touch recovery

      No manual debugging or restart scripts required.

    What is Caylex and how does it work?
    Caylex is a smart coordination layer that connects your AI agents to the tools they rely on — securely, reliably, and at scale. Instead of hardcoding every integration, agents send requests to Caylex through a single endpoint.
    What is an MCP and why does it matter?
    MCP (Multi-Cloud Protocol) is our standardized interface that enables seamless integration with any external service. It provides a unified way to connect your AI agents with tools, services and LLMs across different cloud providers and platforms.
    How does Caylex handle retries and failovers?
    Caylex implements intelligent retry mechanisms and automatic failover handling. If a request fails, it will automatically retry with exponential backoff. For critical services, Caylex can failover to backup endpoints to ensure high availability.
    Can I track performance and usage metrics?
    Yes, Caylex provides comprehensive monitoring and analytics. Track request volumes, latency, error rates, and costs across all your integrations through our dashboard. Custom metrics and alerts can also be configured.
    Do you offer custom plans?
    Yes, we offer flexible pricing plans tailored to your specific needs. Contact our sales team to discuss custom volume pricing, SLAs, and enterprise features that match your requirements.
    How long does it take to deploy Caylex?
    Caylex can be deployed and integrated into your existing infrastructure in minutes. Our quick-start guides and SDKs make it easy to get up and running, with most teams completing basic integration within a day.
