Metamodel

metamodel-app/mcp-server

This server gives Claude access to verified engineering calculations and mathematical models, eliminating the risk of hallucinated formulas or incorrect math. Instead of relying on the LLM to perform complex calculations from memory, you get callable functions that execute actual implementations of engineering equations and models. Reach for this when you're building tools that need real precision in technical domains like structural analysis, thermodynamics, or other fields where getting the math wrong isn't an option. It's the difference between asking an AI to remember a formula versus giving it a calculator that already has the formula programmed correctly.

Install

From registry metadata

$ npx add-mcp https://www.metamodel.app/api/mcp --name metamodel

Run in your terminal. add-mcp asks which agents to add it to (Claude Code, Codex, Cursor and more). Add -g to install it for every project.

Review the command, arguments and environment values before installing. MCP servers run with your local permissions.

Other ways

Claude Code

$ claude mcp add --transport http metamodel https://www.metamodel.app/api/mcp

Run in your terminal. Add --scope user to make it available in every project.

No parameters. Call it with no arguments.

metamodel_get_schemaGet the input/output schema for a published MetaModel project. Returns model names, input parameters (with types, defaults, validation), and output fields.

Parameters* required

inputsobject

Input values as key-value pairs (e.g., {"width": 12}). Auto-routed to the correct model. Omitted inputs use defaults.

modelstring

Target a specific model by name. When omitted, returns outputs from ALL models (recommended).

token*string

The publish token of the project

Readme

MetaModel MCP Server

An MCP (Model Context Protocol) server that lets AI assistants use MetaModel's formula engine for certified computation. Turn published calculators, pricing tools, and engineering models into AI-callable tools — no hallucinated math.

All tools are read-only. This server fetches published project schemas and runs stateless computations. It never writes, modifies, or stores any data.

Quick Start

Remote (hosted) — easiest

No install. Add the URL as a custom connector:

https://www.metamodel.app/api/mcp

Claude.ai / Claude Desktop: Settings → Connectors → Add custom connector → paste the URL
Claude Code: claude mcp add --transport http metamodel https://www.metamodel.app/api/mcp

Works on web and mobile; no Node required. The hosted endpoint is stateless, read-only, and rate-limited.
