Available components
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

- Actively maintained (last published 163 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability83

- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management97
- Stability observed for 29 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the io.github.joegra2003/metamodel MCP server?
io.github.joegra2003/metamodel runs locally as an npm package, launched with npx -y metamodel-mcp. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

- 21 Sept 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 93 to 97. That category is still filling its 30-day observation window: 28 days of observed history at the previous scan, 29 at this one. The score rises as the window fills, whether or not the server changes.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
metamodel_compute ~143
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. Optionally specify a single model to target. Use metamodel_get_schema first to discover available inputs and outputs.
| Name | Type | Req | Description |
|---|---|---|---|
| inputs | object | – | Input values as key-value pairs (e.g., {"width": 12, "height": 8}). Auto-routed to the correct model. Omitted inputs use defaults. |
| model | string | – | Target a specific model by name. When omitted, returns outputs from ALL models (recommended). |
| token | string | yes | The publish token of the project |
No output schema declared.
No examples provided.
metamodel_get_schema ~68
Get the input/output schema for a published MetaModel project. Returns model names, input parameters (with types, defaults, validation), and output fields. Use a token from metamodel_list_projects.
| Name | Type | Req | Description |
|---|---|---|---|
| token | string | yes | The publish token of the project (from metamodel_list_projects) |
No output schema declared.
No examples provided.
metamodel_list_projects ~35
Browse available MetaModel calculators and engineering models. Returns project names, descriptions, tokens, and model names for each published project.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
What is the io.github.joegra2003/metamodel MCP server?
io.github.joegra2003/metamodel is an MCP server listed in the public MCP registry as io.github.joegra2003/metamodel. AI-callable calculators and engineering models with real formulas. No hallucinated math. This page covers its npm package (metamodel-mcp).
Is the io.github.joegra2003/metamodel MCP server safe to use?
io.github.joegra2003/metamodel scores 85 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 21 September 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the io.github.joegra2003/metamodel MCP server expose?
io.github.joegra2003/metamodel exposes 3 tools: metamodel_list_projects, metamodel_get_schema, metamodel_compute. Their descriptions and schemas cost roughly 246 tokens of context every time the server is loaded.
Is the io.github.joegra2003/metamodel MCP server still maintained?
io.github.joegra2003/metamodel is still listed as active in the MCP registry. We last reached this channel on 21 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the io.github.joegra2003/metamodel MCP server under?
io.github.joegra2003/metamodel declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
