## MCP tools (10)

### `search_components` (~157 tokens)

Search SDCStudio's public catalog of published components by label, with optional type (xdstring, xdcount, xdquantity, xdtemporal, cluster, party, ...) and project. Reuse first: a published component that fits is free to assemble; minting a new one costs 100 credits. Returns ct_id, label, description, component_type, project_name and reuse_ref for each result. Free; no key needed.

Input parameters:

- `page` (integer)
- `page_size` (integer)
- `project` (string): Optional project name to filter by, e.g. a public library.
- `query` (string, required): Words from the label or description.
- `type` (string): Optional component type to filter by.

### `list_models` (~46 tokens)

Published data models in the public catalog, by words in the title. Free.

Input parameters:

- `page` (integer)
- `page_size` (integer)
- `query` (string)

### `get_model` (~69 tokens)

One published data model: title, description, project, its components, and the artifact routes (xsd, xml, json, jsonld, html, ttl, shacl, gql, zip). The XSD is the contract every record validates against. Free.

Input parameters:

- `ct_id` (string, required)

### `estimate_model` (~124 tokens)

What assembling this model would reuse, mint and cost, in credits, computed before any money moves. Takes the title and the assembly tree ({label, components: [{ct_id} to reuse or {label, data_type} to mint], clusters: [...]}). Returns estimate_id, the reused and minted leaves, problems in the tree, and total_credits (500 for the model plus 100 per mint). Show the result to the person; build_model needs the estimate_id. Free.

Input parameters:

- `title` (string, required)
- `tree` (object, required): The assembly tree.

### `build_model` (~263 tokens)

Assemble and publish the model the person estimated and approved. Needs the estimate_id from estimate_model for the same title and tree; refuses otherwise, the server refuses a stale one too, and refuses when the estimate exceeds what the key may still spend. Spends credits: 500 for the model plus 100 per minted component or new cluster. With every leaf existing the model is published and its package generated at once (result has ct_id and artifacts); with new leaves the pipeline runs and the result has a job_ct_id to poll with job_status; when the job completes it has published and generated as asked and carries the model's links. publish false leaves a draft for a person to review. A 402 means the wallet needs funding at the wallet page; report it and stop.

Input parameters:

- `contextual` (object): Optional contextual component references (audit, attestation, party, subject, provider, participation, protocol, workflow, acs).
- `description` (string)
- `estimate_id` (string, required)
- `generate` (boolean): Build the package after publishing (needs publish).
- `publish` (boolean): Publish the clusters and the model (false leaves a draft for a person to review).
- `title` (string, required)
- `tree` (object, required)

### `job_status` (~76 tokens)

One job (job_ct_id from build_model): status queued, running, completed or failed; step; cost_credits so far; on completion the model's links (dm_ct_id, catalog_url, package_url); on failure the reason. Poll every few seconds, backing off. Free.

Input parameters:

- `job_ct_id` (string, required)

### `download_package` (~137 tokens)

Download a model's package (the ZIP: schema, XML template and JSON instance of the Governed Data Record, JSON-LD, HTML, RDF, SHACL, GQL) into the server's output directory, with this key: it works for a model in a private project, such as the one build_model just made, where get_model and the public catalog do not. When the model is published and its package not yet built, it builds it first (free, once; it needs the right to publish the model); generate false only downloads. Free.

Input parameters:

- `ct_id` (string, required)
- `generate` (boolean)

### `generate_app` (~124 tokens)

Generate a published model's application (lightweight or enterprise profile; a Django stack on the model package, one example of implementing on it) and download it into the server's output directory. The first download of a model by this user costs 1,500 credits; later downloads of the same model are free. Needs confirm_charge true, after the person has agreed. Prefer the model package (get_model's artifacts) when the feature lives inside an existing application.

Input parameters:

- `confirm_charge` (boolean)
- `ct_id` (string, required)
- `profile` (string)

### `add_supabase_kit` (~202 tokens)

Write a published model's governed data kit into a Supabase project: typed TypeScript for the model's records, the gate (an Edge Function that validates every record against the published model before storing it) and the migrations. The first call writes the project base too; call again for each further model. Components already in the project are never rewritten, and each migration is written once, numbered after the project's latest. Then apply them with Supabase's own CLI or MCP server (supabase db push; supabase functions deploy gate). The first download of a model by this user, kit or application, costs 1,500 credits; later downloads of the same model are free. Needs confirm_charge true, after the person has agreed.

Input parameters:

- `confirm_charge` (boolean)
- `ct_id` (string, required)
- `project_dir` (string): The project holding supabase/, relative to the server's output directory. Default: the output directory.

### `wallet` (~32 tokens)

The wallet balance in credits and this key's policy: scopes, spending limit, what it has spent, expiry. Free.

## Common questions

### What is the io.github.Axius-SDC/sdcmodeler MCP server?

io.github.Axius-SDC/sdcmodeler is an MCP server listed in the public MCP registry as io.github.Axius-SDC/sdcmodeler. The modeler's client for SDCStudio: search the catalog, estimate, assemble and publish SDC4 models. This page covers its PyPI package (sdcmodeler).

### Is the io.github.Axius-SDC/sdcmodeler MCP server safe to use?

io.github.Axius-SDC/sdcmodeler scores 85 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. Its build provenance is signed and verified. 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.Axius-SDC/sdcmodeler MCP server expose?

io.github.Axius-SDC/sdcmodeler exposes 10 tools: search_components, list_models, get_model, estimate_model, build_model, and 5 more. Their descriptions and schemas cost roughly 1,230 tokens of context every time the server is loaded.

### Is the io.github.Axius-SDC/sdcmodeler MCP server still maintained?

io.github.Axius-SDC/sdcmodeler is still listed as active in the MCP registry. We last reached this channel on 5 November 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.Axius-SDC/sdcmodeler MCP server under?

io.github.Axius-SDC/sdcmodeler declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the io.github.Axius-SDC/sdcmodeler MCP server?

VerifyMCP ran 16 checks on io.github.Axius-SDC/sdcmodeler, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to a PyPI package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
