MCP tools · 13 exposed · ~1,696 tokens

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 →

Tool Tokens
core_models_get_mixins_info ~65

Get information about all mixins in a CoreModels project. Mixins define structured metadata used for mapping models, system integrations, and other extensions. Use get_node tool documentation to understand how mixins are attached to nodes.

NameTypeReqDescription
graphProjectIdstringyes–

No output schema declared.

No examples provided.

core_models_get_relation_groups_info ~44

Get information about relation groups for a CoreModels project. Use the relation groups to create a relation between two nodes.

export_json_ld ~231

Export project data in JSON-LD format using a configured export profile. Use `fetch_json_ld_import_profiles` first to discover the configTypeId. At least one of exportTypes/exportElements/exportTaxonomies/exportDataTypes must be true. Tree-based mode (graphBased=false) requires exactly one nodeId; graph-based mode allows multiple or none.

NameTypeReqDescription
graphProjectIdstringyes–

No output schema declared.

No examples provided.

get_mixins_and_relation_groups ~80

Get the project schema: all mixin definitions and all relation-group definitions. Use this once at the start of a session to discover the IDs needed by other tools (mixinId, columnId, relationGroupId). Returns compact positional arrays - see the "format" field for the layout.

NameTypeReqDescription
graphProjectIdstringyes–

No output schema declared.

No examples provided.

get_project_summary ~107

Labels and IDs of types, elements, and taxonomies in the project. Each category is paginated independently. Pagination: - First call: omit page (defaults to 0). - Each category reports page, pageSize and hasMore. Re-request with page+1 for any category whose hasMore is true.

NameTypeReqDescription
graphProjectIdstringyes–
pageinteger–0-based page index, applied independently to each category.
pageSizeinteger––

No output schema declared.

No examples provided.

list_projects ~237

List the user's CoreModels projects as [id,name,accessLevel] (see the response "format" field). Use a returned id as graphProjectId for other tools. Pass searchTerm to filter by name (case-insensitive substring). Set includePublicProjects=true to also include public projects. Set includeAISummary=true to also return each project's saved AI-generated summary and the time it was generated (4th and 5th elements). Paged: page is 1-based; increment page up to the returned totalPages to get all results.

NameTypeReqDescription
includeAISummaryboolean–When true, each project row includes its saved AI-generated summary (markdown) and the time it was generated as 4th and 5th elements, or null if none has been generated.
includePublicProjectsboolean–When true, public projects the user is not a member of are also included.
pageinteger–1-based page number. Increment to page through results up to totalPages.
pageSizeinteger––
searchTermstring–Optional case-insensitive substring to filter projects by name.

No output schema declared.

No examples provided.

run_code ~240

Execute a JavaScript program that orchestrates this server's tools, and return only its result. Prefer this over many individual tool calls when a task needs several steps, looping, filtering, or combining data: intermediate results stay in the sandbox, so only what you return reaches the model. Inside the script: - listTools() -> [{name, summary}] discover available tools - getToolDoc(name) -> {name, description, parameters, required} inspect one tool's inputs - tools.<name>(args) -> parsed result call a tool (graphProjectId is injected automatically; do NOT pass it) - console.log(...) captured and returned alongside the result - return <value> JSON-serialized and returned Environment: sandboxed JavaScript, no network or filesystem, with limits on time, memory, statements and number of tool calls. Currently only read-only tools are callable from code.

NameTypeReqDescription
codestringyesJavaScript to execute. Use tools.<name>(args), listTools(), getToolDoc(name); end with `return <value>`.
graphProjectIdstringyes–

No output schema declared.

No examples provided.

search_nodes ~325

Search nodes in a CoreModels project. Returns compact positional arrays; the response "format" field describes the layout. Filters (provide at least one; they combine with AND): - nodeIds: exact id lookup - nodeType: one of Element, Type, Taxonomy, Exemplar, Component, Space, Tag, Mixin - expression: partial substring match on the node label (plain text, no wildcards) - spaceIds: restrict to specific spaces Optional flags: includeRelations, includeMixins, sortAttr, sortDesc, pageSize. Pagination: - First call: omit pagingToken. - If the response has a pagingToken, more pages exist. Repeat the same call with that exact token to get the next page. - If the response has no pagingToken, this was the last page.

NameTypeReqDescription
expressionstring–Partial substring match against the node label. Plain text only - no wildcards, no regex, no '*', '%', '_' or '?' characters; the literal characters are matched as-is.
graphProjectIdstringyes–
includeMixinsboolean––
includeRelationsboolean––
nodeIdsarray––
nodeTypestring––
pageinteger–1-based page number. The response includes 'total' (the total match count) so you can compute how many pages there are.
pageSizeinteger––

No output schema declared.

No examples provided.

validate_json ~136

Validate a JSON document against a project's stored JSON Schema. The schema is regenerated from the project using the supplied configTypeId (the export profile id) and rootNodeId. Provide the JSON to validate as a serialized string.

NameTypeReqDescription
configTypeIdstring–Profile id used to map mixins/relations to schema keywords

Install

How do I install the io.github.qg-aramai/coremodels MCP server?

io.github.qg-aramai/coremodels is a hosted endpoint at https://go.coremodels.io/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Common questions

What is the io.github.qg-aramai/coremodels MCP server?

io.github.qg-aramai/coremodels is an MCP server listed in the public MCP registry as io.github.qg-aramai/coremodels. Schema modeling in JSON, JSON-LD, and other formats with CoreModels platform. This page covers its hosted endpoint (https://go.coremodels.io/mcp).

Is the io.github.qg-aramai/coremodels MCP server safe to use?

io.github.qg-aramai/coremodels scores 36 out of 100 on VerifyMCP. 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.qg-aramai/coremodels MCP server expose?

io.github.qg-aramai/coremodels exposes 13 tools: export_json_ld, fetch_json_ld_import_profiles, export_jsonschema, fetch_json_schema_import_profiles, validate_json, and 8 more. Their descriptions and schemas cost roughly 1,696 tokens of context every time the server is loaded.

Does the io.github.qg-aramai/coremodels MCP server require authentication?

Yes. io.github.qg-aramai/coremodels asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

Is the io.github.qg-aramai/coremodels MCP server still maintained?

io.github.qg-aramai/coremodels 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.
