Documentation Overview

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)

bash

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

Install

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

https://github.com/arunmm8335/sysmcp/releases

bash

# example amd64
curl -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

Or from source:

bash

go install github.com/arunmm8335/sysmcp/cmd/sysmcp@latest
# or
git clone https://github.com/arunmm8335/sysmcp.git
cd sysmcp
go build -o sysmcp ./cmd/sysmcp

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):

bash

# 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

config.json

{
  "mcpServers": {
    "sysmcp": {
      "command": "/absolute/path/to/sysmcp"
    }
  }
}

Enable eBPF (optional)

bash

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.

Demo

bash

go test ./... -count=1
go build -o sysmcp ./cmd/sysmcp
go run ./scripts/smoke.go ./sysmcp
./sysmcp serve   # then open http://127.0.0.1:8787/
