milind-soni/mcpd

One host for all your MCP servers — shared instances, lazy start, live dashboard, a fraction of the RAM. Includes MCP servers compiled to native binaries with scriptc.

About mcpd

Every MCP client — Claude Code, Claude Desktop, Cursor — spawns its own copy of every server you've configured, per window. Dozens of invisible processes, gigabytes of RAM, no way to see any of it.

mcpd is a single daemon that owns your servers instead:

- One shared instance per server, across every client and window - Lazy start — servers spawn on first call, stop after 5 idle minutes - Visibility — live dashboard and mcpd status: state, memory, calls, last used - Zero dependencies — plain Node 20+

Bonus: sessions share server state — store a fact in the memory server from one Claude session, recall it from another.

Point your clients at mcpd instead of spawning servers:

mcpd speaks streamable HTTP to clients and stdio to the servers it supervises. Each server's initialize handshake happens once; every client's handshake is answered from cache, and requests are forwarded with remapped ids. To each client it looks like a private server.

mcpd supervises any command — including MCP servers compiled to native binaries with scriptc.

examples/sequential-thinking-native is Anthropic's official sequential-thinking server ported to 259 lines of plain TypeScript and compiled statically. Tool outputs byte-identical to the original:

native (scriptc) official (node) --------------- ---------------- ----------------------- size on disk 554KB ~102MB (package + Node) startup 1.9ms 86ms memory 1.6MB 79MB
