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 ", pty=true) if needed
