Struct McpServer 

pub struct McpServer {
    pub name: String,
    pub pid: Option<u32>,
    pub cmdline: Option<String>,
    pub cpu_percent: f32,
    pub rss_bytes: u64,
    pub age_secs: Option<u64>,
    pub calls: u64,
    pub errors: u64,
    pub last_call: Option<SystemTime>,
    pub matched_by: McpMatch,
}

One MCP server an agent uses, seen from either side or both: the process table has the server’s pid, CPU and memory; the transcript has how often the agent called it. Claude Code names an MCP tool mcp__<server>__<tool>, which is where the server name and the call count come from.

Fields

name: String

The server’s name as the harness configured it, or, for a process the transcript never named, the program it is running.

pid: Option<u32>

cmdline: Option<String>

cpu_percent: f32

rss_bytes: u64

age_secs: Option<u64>

calls: u64

Tool calls the agent made to this server, from the transcript.

errors: u64

Of those, how many the harness reported as errors.

last_call: Option<SystemTime>

matched_by: McpMatch

How the process and the transcript’s server were put together, for the UI to label a guess as one.
