Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

MCPorter

Call MCP server tools via CLI without a persistent connection. Keeps tool schemas out of context.

Quick Start

mcporter list                          # available servers
mcporter list  --schema        # tools + args (always run before first call)
mcporter call . key:val  # call a tool

Rules

  • Always run mcporter list --schema before first call — tool names drift between versions.
  • If a server is offline or auth-gated, report it and continue with fallback tools.

Non-Obvious Workflows

Chrome live-session debugging

Connects to the user's running Chrome with existing login state and cookies. Requires Chrome remote debugging and user consent prompt approval.

mcporter list chrome-devtools --schema
mcporter call chrome-devtools.list_pages
mcporter call chrome-devtools.select_page pageIndex:0
mcporter call chrome-devtools.take_screenshot
mcporter call chrome-devtools.evaluate_script function:"() => document.title"

When to use mcporter vs direct MCP

  • mcporter: One-off or infrequent tool calls. Keeps context clean.
  • Direct MCP: Frequent use in a session, need streaming, tight integration.
