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 →

What is the VULK MCP server?
VULK is an MCP server listed in the public MCP registry as io.github.devjoaocastro/vulk-mcp-server. Generate, edit, and deploy immersive 3D/WebGL web projects from any MCP assistant. This page covers its npm package (vulk-mcp-server).
Is the VULK MCP server safe to use?
VULK scores 84 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 21 September 2026. It declares no install or post-install scripts. 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 VULK MCP server expose?
VULK exposes 19 tools: create_visual_brief, create_project, generate_immersive_site, edit_project, list_projects, and 14 more. Their descriptions and schemas cost roughly 1,124 tokens of context every time the server is loaded.
Is the VULK MCP server still maintained?
VULK is still listed as active in the MCP registry. We last reached this channel on 21 September 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 VULK MCP server under?
VULK declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
