As a local MCP server: PyPI package
Built from what Official MCP Registry declares.
claude mcp add --transport stdio cogvault -- uvx cogvault[mcp_servers.cogvault]
command = "uvx"
args = ["cogvault"]{
"mcpServers": {
"cogvault": {
"command": "uvx",
"args": [
"cogvault"
]
}
}
}Optional settings it also lists: COGVAULT_LOG, COGVAULT_MODEL.
We do not store launch arguments. If the server needs any, its own documentation names them.

Found by meaning, not by shared code or a shared repository: similar plugins stay separate products, and this is not a review or a recommendation.
Is this your plugin?
Add it to your projects and prove you maintain it with a file in its repository, a file on your domain or a DNS record. You get alerts when a marketplace lists it, drops it, changes its verified mark or what it asks for, and its remote endpoint goes on monitoring as a web service.
Data comes from the Official MCP Registry (registry.modelcontextprotocol.io), CC0 1.0. Figures come from our own regular passes over the marketplaces, last read on . We publish no contact details for plugin publishers.
