# Resource Limit Calculator MCP for AI Agents AI Agent Connect

> Resource Limit Calculator MCP converts high-level resource requirements into precise OS-level kernel constants. It helps you define strict execution boundaries for autonomous agents by translating memory, CPU time, and file size constraints into specific rlimit values like rlimitCpu and rlimitAs. This ensures your sandboxed environments remain secure and predictable.

## Description

Setting up a sandbox for an autonomous agent usually involves a lot of guesswork. You know you want to limit memory to 512MB or cap execution time to 30 seconds, but translating those human-readable numbers into the specific kernel constants the operating system actually understands is a headache. If you get it wrong, your agent might crash the host or run away with all your CPU cycles. This MCP removes that friction. It acts as a bridge between your intent and the OS, turning vague constraints into the exact technical parameters needed to lock down a process. By connecting this to your AI client through the Vinkius catalog, you can instantly generate the precise limits required to keep your agent environments stable. Instead of manually looking up rlimit values or testing limits until they break, you just state what you need and get the exact configuration to keep your sandboxed processes within their lane.

## Tools

### calculate_os_limits
Converts high-level resource needs into specific OS-level constants. It's the primary way to get exact rlimit values.

### estimate_instruction_budget
Calculates the total CPU instruction cycles available for a process. This helps prevent infinite loops in agent code.

### validate_sandbox_configuration
Checks if your calculated limits fit within specific hardware profiles. It ensures your settings won't fail on target hardware.

## Prompt Examples

**Prompt:** 
```
I need to limit an agent to 256MB of memory and 1 second of CPU time. What are the OS limits?
```

**Response:** 
```
Based on your requirements, here are the calculated OS-level constants:

| Constant | Value |
| :--- | :--- |
| **rlimitAs** | 268435456 |
| **rlimitCpu** | 1 |

These values will ensure the process stays within your 256MB memory and 1-second CPU time constraints.
```

**Prompt:** 
```
How many instruction cycles can I give a process if it has 5 seconds at 2.5 GHz?
```

**Response:** 
```
For a process running at 2.5 GHz for 5 seconds, the estimated budget is:

**12,500,000,000 instruction cycles**

You can use this number to set a ceiling on the computational work the agent performs.
```

**Prompt:** 
```
Is a 2GB memory limit okay for a micro profile?
```

**Response:** 
```
No, that limit is too high. 

* **Status:** Rejected
* **Reason:** The requested 2GB exceeds the maximum allowed bounds for the **micro** hardware profile.
* **Recommendation:** Use the **standard** or **heavy** profile to accommodate this memory requirement.
```

## Capabilities

### Convert constraints to kernel constants
Turn human-readable memory and time limits into specific OS-level rlimit values.

### Calculate CPU instruction budgets
Determine the approximate number of instruction cycles a process can execute before being throttled.

### Verify sandbox safety
Check if your proposed resource limits are compatible with specific hardware profiles like micro or standard environments.

### Define file and descriptor limits
Set exact boundaries for file sizes and the number of open files a process can handle.

## Use Cases

### Preventing infinite loops in agent code
An engineer needs to ensure a code-executing agent doesn't hang the system. They use estimate_instruction_budget to set a hard cycle limit.

### Hardening sandboxes for untrusted code
A security engineer uses calculate_os_limits to translate a 256MB memory requirement into an rlimitAs constant for a new sandbox.

### Validating micro-instance deployments
An ops engineer uses validate_sandbox_configuration to make sure an agent's memory needs won't exceed the limits of a micro-profile instance.

### Managing file system access
A developer uses the tool to set rlimitNofile and rlimitFsize to prevent an agent from filling up the disk or opening too many handles.

## Benefits

- Stop manual math by using calculate_os_limits to get exact rlimit values instantly.
- Prevent runaway processes by using estimate_instruction_budget to cap CPU usage.
- Avoid deployment failures by using validate_sandbox_configuration against specific hardware profiles.
- Ensure sandbox security by translating memory and file constraints into strict OS constants.
- Reduce infrastructure overhead by setting precise limits that match your actual needs.

## How It Works

The bottom line is you stop guessing at kernel parameters and start using exact OS constraints.

1. Tell your agent the resource limits you want, such as memory in MB or CPU time in seconds.
2. The MCP processes these requirements against OS-level logic.
3. You receive the exact rlimit constants ready to be applied to your sandbox configuration.

## Frequently Asked Questions

**How can I use Resource Limit Calculator to secure my agents?**
You use it to translate your security policies into exact kernel limits. By defining strict memory, CPU, and file size constraints, you ensure your agents stay within a safe sandbox.

**Can Resource Limit Calculator help prevent infinite loops?**
Yes. By calculating the instruction budget, you can set a limit on the actual number of CPU cycles an agent is allowed to use, which prevents runaway loops from consuming your host resources.

**Does Resource Limit Calculator work with different hardware profiles?**
Yes. You can use it to check if your chosen resource limits are actually compatible with the specific hardware profile, such as micro or standard, that you are deploying to.

**What is the difference between memory limits and instruction budgets?**
Memory limits (like rlimitAs) restrict how much RAM a process can use, while instruction budgets limit how much actual work the CPU performs, helping to prevent CPU exhaustion.

**How do I get the exact values for rlimit constants?**
You simply tell your agent the human-readable limits you want, and the MCP converts them into the specific rlimit constants required by the operating system.

**What are RLIMITs?**
RLIMITs are kernel-level constraints applied to a process to limit its consumption of system resources like CPU time and memory.

**How do I check if my limits are safe?**
You can use the `validate_sandbox_configuration` tool to verify if your requested limits fit within predefined environment profiles.

**Can I estimate CPU work capacity?**
Yes, the `estimate_instruction_budget` tool allows you to calculate the approximate number of CPU instruction cycles available based on time and frequency.
