@negotium/mcp-host

Process manager for MCP servers hosted by a Negotium node. It owns the MCP manifest, transport selection, loopback port allocation, health checks, idle eviction, and coordinated shutdown.

bun add @negotium/mcp-host

import { McpHost, McpManifest } from "@negotium/mcp-host";

const manifest = new McpManifest();
manifest.add({
  key: "example",
  transport: "stdio",
  command: "bunx",
  args: ["example-mcp-server"],
  scope: "node",
});

const host = new McpHost({ manifest });
await host.ensure("example");
await host.stopAll();

Most applications should install @negotium/node, which wires this package to the runtime. Requires Bun 1.2.15 or newer.
