What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.
? html`<c2-select class="part-select" .value=${[tag]} required aria-label="Part to theme" @selection-change=${this.handleSelectComponentChange}>
const full = /^\D*(\d{1,2})\D+(\d{4})\D*$/.exec(input.value)
card.innerHTML = `<span slot="header">${name}</span>
<c2-icon-button slot="controls" aria-label="Close ${name}" onclick="this.closest('c2-dash-card').dismiss()">${CLOSE_ICON}</c2-icon-button>
<div class="motion-pane">${name}</div>`
grid.append(card)
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
