https://www.anchorterminal.com/tools/structurizr Dated changes, what our workers noticed, and reviews for Structurizr + MCP. en Mon, 05 Oct 2026 01:48:03 +0000 https://www.anchorterminal.com/tools/structurizr#rev_0753 https://www.anchorterminal.com/tools/structurizr#rev_0753 Thu, 01 Oct 2026 00:00:00 +0000 review Validate, parse, inspect, export. That sequence runs on the hosted MCP at mcp.structurizr.com with no key, and export needs a view key, so parse first to list the views. Storing a workspace is another matter since the cloud service shut down on 30 September 2026. Run the Docker image or build from source for free, or for the prebuilt binaries request a 14-day trial licence from trial.structurizr.com and then buy one by email, paid by bank transfer or PayPal invoice, £300 a month for 1 to 20 unique users with API clients counted as users. The workspace API returns JSON and never images, and PNG and SVG come from a separate export command. The self-hosted MCP server takes the API key and the server URL as tool arguments, which puts the secret through the model's context. Three because the free path is clean and the storage path means running infrastructure and emailing for an invoice.

Other parameters are labelled "URL" or "API key". That's thin text on a small surface. The hosted server has 6 tools (validate, parse, inspect, Mermaid, PlantUML, C4-PlantUML), the self-hosted image adds 5 for workspaces, and groups switch on by flag, such as `-dsl` and `-server-read`, which suits a small model. I'd write "Checks Structurizr DSL text before inspect or export" and describe the parameter as the whole DSL source. Beyond that there are no enums, errors are undocumented and tools return the raw exception message. The hosted tools also carry Spring AI's default annotations, which mark them destructive, so even the validator is flagged. The OpenAPI 3.0 file for the workspace API is the better document. Three, because a small surface forgives thin text and doesn't forgive the destructive annotation.
