Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

metamodel

metamodel_compute

Run a computation on a MetaModel project. Send input values and get computed outputs from all models. Inputs are auto-routed to the correct model by property name. Models marked "presentation": true in results are display scaffolding, not engineering outputs. Use metamodel_get_schema first to discover available inputs and outputs.

metamodel_export_kn

Export a published MetaModel project as KN notation — a human-readable text spelling of the model: nested Component blocks, "Name: value" literals, "Name: expression" formulas, dotted cross-references. Deliberately lossy (rules, indicators, validations, table data and views are omitted). Useful for reading or diffing the engineering knowledge behind a project.

metamodel_get_schema

Get the input/output schema for a published MetaModel project. Returns model names, input parameters (with types, defaults, validation), and output fields. Models marked "presentation": true are display scaffolding (3D scenes etc.) — skip them for engineering analysis. Use a token from metamodel_list_projects.

metamodel_list_projects

Browse available MetaModel calculators and engineering models. Returns project names, descriptions, tokens, and model names for each published project.

Metamodel — questions

Answers built from our own checks of this server.

What can Metamodel do?

It exposes 4 tools, read directly from the server on our last check. Among them: metamodel_compute, metamodel_export_kn, metamodel_get_schema, metamodel_list_projects. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Metamodel working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 304 ms. The bar chart above shows every period we have measured.

How do I connect Metamodel?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Metamodel need an API key?

No. Metamodel completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Metamodel?

It answers our handshake in 304 ms on average, which is faster than 50% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use Metamodel?

The npm package metamodel-mcp was installed 31 times in the last week. Week over week that is -38%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Metamodel open source?

We cannot say either way: written in JavaScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
