mcporter is a skill for Claude Code, Codex from geezerrrr/motive. It costs 41 tokens per session (444 once invoked), scanned A, a copy of mcporter, MIT.

A command-line tool for finding, configuring, authenticating with, and calling MCP servers and their tools. MCP is a standard way for an AI application to connect to external tools and data.

In plain words
What is it for?
Listing available server tools, making tool calls, managing authentication and configuration, running local servers, and generating typed clients.
Why use it?
It gives developers one interface for testing and using different tool servers, whether they run over the network or as local processes. It can also inspect schemas and generate command-line or TypeScript helpers.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mcporter scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

  • Selector: mcporter call linear.list_issues team=ENG limit:5
  • Function syntax: mcporter call "linear.create_issue(title: \"Bug\")"
  • Full URL: mcporter call https://api.example.com/mcp.fetch url:https://example.com
  • Stdio: mcporter call --stdio "bun run ./server.ts" scrape url=https://example.com
  • JSON payload: mcporter call <server.tool> --args '{"limit":5}'

Auth + config

  • Config: mcporter config list|get|add|remove|import|login|logout

Daemon

  • mcporter daemon start|status|stop|restart

Codegen

  • CLI: mcporter generate-cli --server <name> or --command <url>
  • Inspect: mcporter inspect-cli <path> [--json]

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
