Overview

AI-generated overview

A remote MCP endpoint offering deterministic calculators for AI and LLM costs across tokens, providers, RAG, agents, evals, and automation.

What it does
Model Ruler exposes deterministic cost calculators for AI and LLM usage. According to its registry description, it covers token, provider, RAG, agent, eval, and automation cost calculations. The manifest lists no tools, so the exact tool names and inputs are not documented here. It runs as a remote streamable HTTP endpoint rather than a local package.
When to use it
Worth considering when an assistant needs to estimate or compare AI and LLM spending, for example budgeting token usage, comparing providers, or costing RAG pipelines, agent runs, evaluations, or automation workflows. It is a calculation aid, not a data source for live pricing unless the service itself provides that.
Requirements
A remote MCP client that supports streamable HTTP, connecting to the provider's endpoint. No packages, environment variables, headers, or authentication are declared in the manifest, and no account or API key is listed.
Before you install
The server is operated by a third party, so any inputs sent to it leave the user's machine; avoid submitting confidential prompts, pricing contracts, or usage data unless that is acceptable. No authentication is declared, so do not assume requests are private or access-controlled. The manifest lists no tools, so verify actual behavior before relying on results.
