As a local MCP server: npm package
Built from what Official MCP Registry declares.
claude mcp add --env "ARBITER_PRIVATE_KEY=<YOUR_ARBITER_PRIVATE_KEY>" --transport stdio arbiter -- npx -y @arbiterlabs/mcp[mcp_servers.arbiter]
command = "npx"
args = ["-y", "@arbiterlabs/mcp"]
[mcp_servers.arbiter.env]
ARBITER_PRIVATE_KEY = "<YOUR_ARBITER_PRIVATE_KEY>"{
"mcpServers": {
"arbiter": {
"command": "npx",
"args": [
"-y",
"@arbiterlabs/mcp"
],
"env": {
"ARBITER_PRIVATE_KEY": "<YOUR_ARBITER_PRIVATE_KEY>"
}
}
}
}Replace the values in angle brackets with your own. We show the names of the settings, never values.
Optional settings it also lists: ARBITER_MAX_PRICE_PER_CALL, ARBITER_MAX_SPEND_USD, ARBITER_URL.

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.
