Helps you discover, authenticate, and call MCP servers from the terminal. MCP connects agents to external tools. You can inspect available tools, manage connections, make one-off calls, and generate command-line wrappers or TypeScript clients.
List, auth, and call MCP servers/tools from the terminal.
Review the instructions the agent will receive before you install.
Use mcporter to discover, call, and manage MCP (Model Context Protocol) servers and tools directly from the terminal.
Requires Node.js:
# No install needed (runs via npx)
npx mcporter list
# Or install globally
npm install -g mcporter
# 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
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
# 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
# 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).
For persistent server connections:
mcporter daemon start
mcporter daemon status
mcporter daemon stop
mcporter daemon restart
# 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

Set up the 1Password CLI and use stored passwords or API keys in commands and configuration templates. Choose an authentication method, retrieve secret references, and pass credentials to processes through environment variables.
Build an Excel workbook linking the income statement, balance sheet, and cash flow statement. Populate historical figures, create formula-based forecasts, compare scenarios, and check that balances and cash totals agree across all three statements.
Adapt existing PyTorch training scripts to use multiple GPUs or machines with limited code changes. The skill guides configuration, launch commands, mixed precision, which uses lower-precision numbers, and DeepSpeed or FSDP settings for distributing training work and memory.
Configure Hermes to run AI models through Actual Computer on your own hardware. Set up either the hosted relay or a local connection, select models, verify responses, and troubleshoot request errors or empty output.
Test an app from the perspective of a frustrated, less technical user. Find confusing steps and barriers, separate actionable usability problems from personal complaints, and produce screenshots, suggested fixes, and prioritized tickets.
Resolve Git merge conflicts between two agents by comparing both changes and their stated goals. Combine compatible work, explain choices where designs differ, and verify the merged result with project builds or tests.
