Fast terminal calculations with Claude Code

The `calculate_percentage` tool gives your terminal agent the ability to parse system logs and compute resource usage metrics on the fly. When you pipe command outputs into Claude Code, it uses this tool to calculate disk space percentages or CPU load ratios instantly. This means your CLI agent doesn't need to consult a cloud LLM for basic arithmetic. It processes the numbers locally, keeping your shell scripts fast and your terminal session responsive.

Scale scripts using rule of three and powers

The `calculate_rule_of_three` tool allows your command-line agent to scale system configurations and resource limits proportionally. Claude Code pairs this with `calculate_power` to estimate exponential backoff times or database storage growth. Running these calculations locally via our MCP Server prevents network latency from slowing down your CI/CD pipelines. Your agent gets deterministic results in milliseconds, ensuring your scripts run without interruption.

Run factorials and roots directly in the shell

The `calculate_factorial` tool provides rapid combinatorial calculations for complex command-line scripts. Claude Code uses this tool alongside `calculate_square_root` to analyze system metrics or compute variance in performance logs. Since Vinkius handles the hosting and security, your terminal agent accesses these tools with a single command. You get raw mathematical precision injected directly into your terminal output.

Setup guide

Set up Fundamental Math MCP in Claude Code

Prerequisites

Claude Code CLI installed (npm install -g @anthropic-ai/claude-code)
Active Vinkius subscription with a valid endpoint token

1

Run the add command

Open your terminal and run the command shown on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com. Use --scope user to make it available across all projects.
2

Verify the connection

Start a Claude Code session and type /mcp to list connected servers. You should see fundamental-math-mcp with a green status indicator.
3

Start using tools

Ask Claude Code something like "Check my latest Fundamental Math transactions." It will automatically discover and invoke the available Fundamental Math tools.

Common questions about Fundamental Math MCP in Claude Code

Run the command `claude mcp add --transport http fundamental-math -- ` in your terminal. This registers the server in your ~/.claude.json file so your CLI agent can access the tools.

Yes, Claude Code can invoke these tools during automated tasks or shell scripts. It uses `calculate_percentage` and `calculate_power` to process pipeline metrics without manual prompts.

While bash can handle basic math, this server lets Claude Code execute complex operations like `calculate_factorial` and `calculate_square_root` natively inside its reasoning loop. This prevents parsing errors and keeps your automation scripts clean.

No, the calculations run locally in a secure sandbox once the server is connected. Your terminal agent processes all math operations with zero network latency.

Yes, all numbers, inputs, and math results are handled in a secure, ephemeral V8 sandbox. Your calculation parameters are never sent to external servers or used for model training.
