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.

com.vaadin/docs-mcp is listed in the public MCP registry as com.vaadin/docs-mcp. Provides Vaadin Documentation and help with development tasks. This page covers its hosted endpoint (https://mcp.vaadin.com/docs/).
Is the com.vaadin/docs-mcp server safe to use?
com.vaadin/docs-mcp scores 25 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 com.vaadin/docs-mcp server expose?
com.vaadin/docs-mcp exposes 11 tools: get_vaadin_primer, search_vaadin_docs, get_full_document, get_latest_vaadin_version, get_supported_vaadin_versions, and 6 more. Their descriptions and schemas cost roughly 1,443 tokens of context every time the server is loaded.
Does the com.vaadin/docs-mcp server require authentication?
Its publisher declares no required credentials for com.vaadin/docs-mcp. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.
Is the com.vaadin/docs-mcp server still maintained?
com.vaadin/docs-mcp 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.
