Common questions
Is sysmcp safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.5.0) reached the registry 4 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need MCPB on your computer.
What can I use instead?

sysmcp
MCP server that exposes live host signal — CPU, memory, processes, network — to Cursor / Claude. Default path is /proc (no root). Optional eBPF tools activate when CAP_BPF / CAP_PERFMON is available.
Repo: https://github.com/arunmm8335/sysmcp · Version: 0.5.0
Tools
| Tool | What it returns |
|---|---|
host_dashboard | Full snapshot (CPU, mem, top procs, listeners, eBPF) |
poll_host_stats | Lightweight CPU/mem/process snapshot for auto-refresh |
system_stats | CPU %, memory %, load averages, NIC rx/tx B/s |
top_processes | Top PIDs by CPU % over a sample window, plus skipped_count |
network_connections | IPv4+IPv6 TCP/UDP; filters + resolve_pid; row limit (default 200) |
cgroup_cpu | Top cgroups by CPU % (cgroup v2 cpu.stat) |
iface_rates | Per-interface byte/packet rates (/proc/net/dev) |
ebpf_status | Whether eBPF works; includes how_to_enable when not |
ebpf_activity | Fork + sched_switch rates via eBPF, or available: false |
ebpf_traffic | Kernel RX/TX packet rates (netif_receive_skb / net_dev_xmit) |
True per-connection byte counters need sock-level eBPF; iface_rates + ebpf_traffic are the practical deeper network signal today.
Browser dashboard (HTTP)
go build -o sysmcp ./cmd/sysmcp./sysmcp serve
open http://127.0.0.1:8787/
Optional: ./sysmcp serve -addr 127.0.0.1:9000
APIs: /api/dashboard, /api/poll (JSON).
Interactive views in Cursor
Ask *“Open the host dashboard”* / *“Refresh the host dashboard”*. The agent calls host_dashboard and opens a Cursor Canvas beside the chat.
MCP Apps resource ui://sysmcp/dashboard remains for hosts that render Apps iframes. Cursor often uses Canvas + JSON instead.
network_connections filters
| Arg | Effect |
|---|---|
listen_only | TCP LISTEN + unbound UDP |
protocol | tcp / udp |
family | ipv4 / ipv6 |
state | e.g. ESTABLISHED, LISTEN |
local_port | filter by local port |
pid | owning PID (implies resolve_pid) |
limit | max rows (default 200, max 1000); truncated in result |

Release binaries (linux amd64 / arm64) ship on each v* tag:

# example amd64curl -fsSL -o sysmcp.tgz \ https://github.com/arunmm8335/sysmcp/releases/download/v0.5.0/sysmcp_0.5.0_linux_amd64.tar.gz tar -xzf sysmcp.tgz

MCP Registry (one-click)
Namespace: io.github.arunmm8335/sysmcp. Tag releases build .mcpb assets and attempt an OIDC publish via mcp-publisher. To publish manually after a release (recommended if OIDC is not set up):
# fill fileSha256 in server.json from the release *.mcpb.sha256 files, then:curl -fsSL -o mcp-publisher.tgz \ https://github.com/modelcontextprotocol/registry/releases/download/v1.8.0/mcp-publisher_linux_amd64.tar.gz tar -xzf mcp-publisher.tgz mcp-publisher ./mcp-publisher login github ./mcp-publisher publish ./server.json
See https://modelcontextprotocol.io/registry/quickstart
Cursor / Claude MCP config
{"mcpServers": { "sysmcp": { "command": "/absolute/path/to/sysmcp" } } }
Enable eBPF (optional)
go build -o sysmcp ./cmd/sysmcp./scripts/grant-caps.sh ./sysmcp
sets: cap_bpf,cap_perfmon+ep
Restart the MCP server after granting caps. Without caps, eBPF tools return available: false — /proc tools still work.
