SkeletIQ vs Structura
A side-by-side look at the SkeletIQ and Structura MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose SkeletIQ for coding agents work as a local process; choose Structura for coding agents over a hosted endpoint. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose SkeletIQ when
- You need dedicated capabilities in the Coding Agents domain.
- You prefer a local stdio subprocess transport.
- You have the keys it needs:
SKELETIQ_API_KEY, SKELETIQ_API_URL. - You want tools like
list_projects, get_design, generate_architecture.
Choose Structura when
- You need dedicated capabilities in the Coding Agents domain.
- You prefer a remote HTTP/SSE transport.
- You want tools like
list_projects, create_project, load_project.

Tools & capabilities
SkeletIQ tools 6
list_projectsFind a project by name. Returns the candidates rather than guessing between them.get_designRead a design, in one of six modes: `overview`, `component`, `brief`, `readiness`, `build_order`, `gaps`. Where a version records its requirements, `overview` and `component` resolve the design's `R`-ids to the requirements they name, and say what became of each.generate_architectureDesign a system from a prompt. Spends credits and takes minutes. A prompt that states no load comes back with a question instead, and nothing is charged: ask your human, and answer "Not sure yet" when they do not know rather than guessing.get_generation_statusPoll a generation started with `wait: false`.critique_architectureCheck a design against SkeletIQ's rules. Deterministic, free, stores nothing. Tell it the `domain` and the `exposure`.check_driftReport what you built; hear what is missing, half done, or not in the design.
Structura tools 13
list_projectsList the caller's Structura projects.create_projectCreate a new project, optionally seeded with Structura DSL content.load_projectLoad a project the caller owns, by id.update_projectUpdate a project's name, description, or DSL content.delete_projectPermanently delete a project the caller owns.share_projectFind or create a viewable share link for a project.query_modelQuery a model's nodes, optionally filtered by node type.summarize_modelSummarize a model (node counts by type, connection count).get_project_statisticsCompute model statistics (class/association counts, connectivity averages, etc.).list_generatorsList available code generators and their configurable options.generateSubmit an async code-generation job for a project against a chosen generator.get_generation_statusPoll a generation job's status until it completes.- +1 more on the listing page

Frequently asked questions
SkeletIQ is categorized under Coding Agents and uses a local stdio subprocess. Structura belongs to Coding Agents and uses a remote HTTP/SSE transport. Pick SkeletIQ for coding agents work and Structura for coding agents.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
SkeletIQ has no declared pricing — check the project's own site. Structura has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add skeletiq-2 and structura-2 as separate keys in the same mcpServers object, and your assistant will call tools from either one.
