Use the mcporter CLI to list, configure, auth, and call MCP servers/tools directly (HTTP or stdio), including ad-hoc servers, config edits, and CLI/type generation.

We split this skill into the rules it gives an agent

2 rules. 0 are common, 0 are distinctive, and 2 are very specific to this project.

  • 0

    Common

    Most of the 37 edited versions we read keep these.

  • 0

    Distinctive

    This author's own choices. Worth a look.

  • 2

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Very specific
  1. Very specific:

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

    line 17
  2. Very specific:

    Use --output json for structured output that's easier to parse

    line 120

“Common” is measured: kept by at least 6 in 10 of the 37 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

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

Code Generation

# Generate a CLI wrapper for an MCP server
mcporter generate-cli --server <name>
mcporter generate-cli --command <url>

# Inspect a generated CLI
mcporter inspect-cli <path> [--json]

# Generate TypeScript types/client
mcporter emit-ts <server> --mode client
mcporter emit-ts <server> --mode types

Notes

  • Use --output json for structured output that's easier to parse
  • Ad-hoc servers (HTTP URL or --stdio command) work without any config — useful for one-off calls
  • OAuth auth may require interactive browser flow — use terminal(command="mcporter auth <server>", pty=true) if needed
