mcporter

mcporter is a skill for Claude Code, Codex from johnson7788/MultiUserClaw. It costs 41 tokens per session (816 once invoked), scanned A, a copy of mcporter, MIT.

A command-line tool for discovering and calling MCP servers and their tools. MCP servers are services that make data or actions available to AI clients through a common interface.

In plain words
What is it for?
Use it to list configured servers, view tool schemas, call tools with arguments, connect to HTTP or standard-input/output servers, and generate CLI or type information.
Why use it?
It lets you inspect available servers, configure connections, authenticate, and make one-off tool calls directly from a terminal.

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 4d 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.

Origin

This is a copy

84% identical to mcporter — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

mcporter

Use mcporter to discover, call, and manage MCP (Model Context Protocol) servers and tools directly from the terminal.

Prerequisites

Requires Node.js:

# No install needed (runs via npx)
npx mcporter list

# Or install globally
npm install -g mcporter

Quick Start

# List MCP servers already configured on this machine
mcporter list

# List tools for a specific server with schema details
mcporter list <server> --schema

# Call a tool
mcporter call <server.tool> key=value

Discovering MCP Servers

mcporter auto-discovers servers configured by other MCP clients (Claude Desktop, Cursor, etc.) on the machine. To find new servers to use, browse registries like mcpfinder.dev or mcp.so, then connect ad-hoc:

# Connect to any MCP server by URL (no config needed)
mcporter list --http-url https://some-mcp-server.com --name my_server

# Or run a stdio server on the fly
mcporter list --stdio "npx -y @modelcontextprotocol/server-filesystem" --name fs

Calling Tools

# Key=value syntax
mcporter call linear.list_issues team=ENG limit:5

# Function syntax
mcporter call "linear.create_issue(title: \"Bug fix needed\")"

# Ad-hoc HTTP server (no config needed)
mcporter call https://api.example.com/mcp.fetch url=https://example.com

# Ad-hoc stdio server
mcporter call --stdio "bun run ./server.ts" scrape url=https://example.com

# JSON payload
mcporter call <server.tool> --args '{"limit": 5}'

# Machine-readable output (recommended for Hermes)
mcporter call <server.tool> key=value --output json

Auth and Config

# OAuth login for a server
mcporter auth <server | url> [--reset]

# Manage config
mcporter config list
mcporter config get <key>
mcporter config add <server>
mcporter config remove <server>
mcporter config import <path>

Config file location: ./config/mcporter.json (override with --config).

Daemon

For persistent server connections:

mcporter daemon start
mcporter daemon status
mcporter daemon stop
mcporter daemon restart

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.
