Installation Summary

Tool: mcporter Purpose: TypeScript runtime, CLI, and code-generation toolkit for Model Context Protocol (MCP) Method: Installed via clawhub Status: ✅ Ready

What MCPorter Is

MCPorter helps you lean into “code execution” workflows highlighted in Anthropic’s Code Execution with MCP guidance. It’s a toolkit for:

  • Discovering MCP servers already configured on your system
  • Calling MCP servers directly from TypeScript or CLI
  • Composing richer automations in TypeScript
  • Minting single-purpose CLIs for sharing tools

All of that works out of the box — no boilerplate, no schema spelunking.

Key Capabilities

Zero-Config Discovery

createRuntime() merges your home config (~/.mcporter/mcporter.json[c]), then config/mcporter.json, plus Cursor/Claude/Codex/Windsurf/OpenCode/VS Code imports, expands ${ENV} placeholders, and pools connections so you can reuse transports across multiple calls.

One-Command CLI Generation

mcporter generate-cli turns any MCP server definition into a ready-to-run CLI, with optional bundling/compilation and metadata for easy regeneration.

Typed Tool Clients

mcporter emit-ts emits .d.ts interfaces or ready-to-run client wrappers so agents/tests can call MCP servers with strong TypeScript types without hand-writing plumbing.

Friendly Composable API

createServerProxy() exposes tools as ergonomic camelCase methods, automatically applies JSON-schema defaults, validates required arguments, and hands back a CallResult with .text(), .markdown(), .json(), and .content() helpers.

OAuth and Stdio Ergonomics

Built-in OAuth caching, log tailing, and stdio wrappers let you work with HTTP, SSE, and stdio transports from the same interface.

Ad-Hoc Connections

Point CLI at any MCP endpoint (HTTP or stdio) without touching config, then persist it later if you want. Hosted MCPs that expect a browser login (Supabase, Vercel, etc.) are auto-detected—just run mcporter auth <url> and CLI promotes definition to OAuth on the fly.

Quick Start

MCPorter auto-discovers MCP servers you already configured in Cursor, Claude Code/Desktop, Codex, or local overrides. You can try it immediately with npx — no installation required.

Call Syntax Options

Colon-delimited flags (shell-friendly):

# Function-call style (matches signatures from `mcporter list`)
npx mcporter call linear.create_comment issueId:ENG-123 body:'Looks good!'

# Object style
npx mcporter call 'linear.create_comment(issueId: "ENG-123", body: "Looks good!")'

List your MCP servers:

npx mcporter list

List with schema or all parameters:

npx mcporter list context7 --schema
npx mcporter list https://mcp.linear.app/mcp --all-parameters
npx mcporter list shadcn.io/api/mcp.getComponents

URL + tool suffix auto-resolves:

npx mcporter list https://mcp.linear.app/mcp/create_comment

stdio transport:

npx mcporter list --stdio "bun run ./local-server.ts" --env TOKEN=xyz

New Features

Machine-Readable Output

Add --json to emit a machine-readable summary with per-server statuses (auth/offline/http/error counts). For single-server runs, includes full tool schema payload.

Verbose Config Sources

Add --verbose to show every config source that registered a server name (primary first), both in text and JSON list output.

Ad-Hoc Server Descriptions

You can now point mcporter list at ad-hoc servers: provide a URL directly or use new --http-url/--stdio flags (plus --env, --cwd, --name, or --persist) to describe any MCP endpoint.

Until you persist that definition, you still need to repeat the same URL/stdio flags for mcporter call — the printed slug only becomes reusable once you merge it into a config via --persist or mcporter config add (use --scope home|project to pick write target).

Follow up with mcporter auth https://… (or same flag set) to finish OAuth without editing config. Full details in docs/adhoc.md.

Single-Server TypeScript Headers

Single-server listings now read like a TypeScript header file so you can copy/paste signature straight into mcporter call.

Daemon Support

Chrome DevTools, mobile-mcp, and other stateful stdio servers now auto-start a per-login daemon the first time you call them so Chrome tabs and device sessions stay alive between agents.

Commands:

  • mcporter daemon status — Check whether daemon is running
  • mcporter daemon start — Pre-warm with daemon
  • mcporter daemon stop — Stop daemon
  • mcporter daemon restart — Bounce daemon

All other servers stay ephemeral; add "lifecycle": "keep-alive" to a server entry (or set MCPORTER_KEEPALIVE=name) when you want daemon to manage it.

Friendlier Tool Calls

Function-call syntax: Instead of juggling --flag value, you can call tools as mcporter call 'linear.create_issue(title: "Bug", team: "ENG")'. The parser supports nested objects/arrays, lets you omit labels when you want to rely on schema order, and surfaces schema validation errors clearly.

Shorthand still works: Prefer CLI-style arguments? Stick with mcporter linear.create_issue title=value team=value — the CLI now normalizes all three forms (title:value, title = value, title: value).

Auto-correct: If you typo a tool name, MCPorter inspects the server’s tool catalog, retries when edit distance is tiny, and otherwise prints a “Did you mean…?” hint.

Cheatsheet: See docs/tool-calling.md for quick comparison of every supported call style.

Richer Single-Server Output

mcporter list <server> now prints:

  • TypeScript-style signatures
  • Inline comments
  • Return-shape hints
  • Command examples that mirror new call syntax

Optional parameters stay hidden by default—add --all-parameters or --schema whenever you need full JSON schema.

Installation

Run instantly with npx:

npx mcporter list

Add to your project:

pnpm add mcporter

Homebrew:

brew tap steipete/tap
brew install steipete/tap/mcporter

The tap publishes alongside MCPorter 0.3.2. If you run into issues with an older tap install, run brew update before reinstalling.

One-Shot Calls from Code

import { callOnce } from "mcporter";

const result = await callOnce({
  server: "firecrawl",
  toolName: "crawl",
  args: { url: "https://anthropic.com" },
});

console.log(result); // raw MCP envelope

callOnce() automatically discovers selected server (including Cursor/Claude/Codex/Windsurf/OpenCode/VS Code imports), handles OAuth prompts, and closes transports when it finishes. Ideal for manual runs or wiring MCPorter directly into an agent tool hook.

Compose Automations with Runtime

import { createRuntime } from "mcporter";

const runtime = await createRuntime();
const tools = await runtime.listTools("context7");

const result = await runtime.callTool("context7", "resolve-library-id", {
  args: { libraryName: "react" },
});

console.log(result); // prints JSON/text automatically

await runtime.close(); // shuts down transports and OAuth sessions

Use createRuntime() when you need connection pooling, repeated calls, or advanced options such as explicit timeouts and log streaming. The runtime reuses transports, refreshes OAuth tokens, and only tears everything down when you call runtime.close().

Compose Tools in Code

import { createRuntime, createServerProxy } from "mcporter";

const runtime = await createRuntime();
const chrome = createServerProxy(runtime, "chrome-devtools");
const linear = createServerProxy(runtime, "linear");

const snapshot = await chrome.takeSnapshot();
console.log(snapshot.text());

const docs = await linear.searchDocumentation({
  query: "automations",
  page: 0,
});

console.log(docs.json());

Friendly ergonomics baked into proxy and result helpers:

  • Property names map from camelCase to kebab-case tool names (takeSnapshot → take_snapshot)
  • Positional arguments map onto schema-required fields automatically
  • Option objects respect JSON-schema defaults
  • Results are wrapped in a CallResult, so you can choose .text(), .markdown(), .json(), .content(), or access .raw when you need the full envelope

Drop down to runtime.callTool() whenever you need explicit control over arguments, metadata, or streaming options.

Generate a Standalone CLI

Turn any server definition into a shareable CLI artifact:

# Basic
npx mcporter generate-cli --server https://mcp.context7.com/mcp

# With name override
npx mcporter generate-cli --command https://mcp.context7.com/mcp --name my-cli

# With description
npx mcporter generate-cli https://mcp.context7.com/mcp --description "My custom CLI"

# With bundling (Bun required for --compile)
npx mcporter generate-cli https://mcp.context7.com/mcp --bundle

# Include/exclude tools
npx mcporter generate-cli linear --include-tools create_issue,create_comment
npx mcporter generate-cli linear --exclude-tools delete_issue

New flags:

  • --name — Override inferred CLI name
  • --description — Custom summary in help output
  • --bundle [path] — Emit bundle alongside template
  • --runtime bun|node — Pick runtime for generated code
  • --compile — Emit Bun-compiled binary
  • --include-tools / --exclude-tools — Generate CLI for subset
  • --from <artifact> — Regenerate existing CLI from metadata

Regenerate from artifact:

npx mcporter generate-cli --from dist/context7.js

Inspect:

npx mcporter inspect-cli dist/context7.js

Generate Typed Clients

Use mcporter emit-ts when you want strongly typed tooling without shipping a full CLI.

# Types-only interface (Promise signatures)
npx mcporter emit-ts linear --out types/linear-tools.d.ts

# Client wrapper (creates reusable proxy factory)
npx mcporter emit-ts linear --mode client --out clients/linear.ts

# Include optional fields
npx mcporter emit-ts linear --include-optional --out types/full.d.ts

# JSON summary
npx mcporter emit-ts linear --json

New flags:

  • --mode types (default) — .d.ts interface only
  • --mode client — .d.ts + helper wrapper
  • --include-optional — Show every optional field
  • --json — Emit structured summary instead of logs

Configuration

Manage this file with mcporter config list|get|add|remove|import when you’d rather avoid hand-editing JSON; see docs/config.md for full walkthrough.

List configs:

mcporter config list
mcporter config --source import
mcporter config --json

Add to config:

mcporter config add my-server https://api.example.com/mcp --scope home|project

Remove from config:

mcporter config remove my-server

Import editor-managed entries:

mcporter config import cursor --copy

Config resolution order:

  1. Path via --config (or programmatic configPath)
  2. MCPORTER_CONFIG environment variable
  3. <root>/config/mcporter.json inside current project
  4. ~/.mcporter/mcporter.json or ~/.mcporter/mcporter.json[c] if project file is missing

Debug Hanging Servers

Quickly use tmux to keep long-running CLI sessions visible while you investigate lingering MCP transports:

tmux new-session -- pnpm mcporter:list

Let it run in the background, then inspect the pane (tmux capture-pane -pt <session>), tail stdio logs, or kill the session once command exits.

Pair this with MCPORTER_DEBUG_HANG=1 when you need verbose handle diagnostics.

More detail: docs/tmux.md and docs/hang-debug.md.

Testing and CI

CommandPurpose
pnpm checkBiome formatting plus Oxlint/tsgolint gate
pnpm buildTypeScript compilation (emits dist/)
pnpm testVitest unit and integration suites (streamable HTTP fixtures included)

CI runs the same trio via GitHub Actions.

Daemon Details

Keep-alive servers:

  • Chrome DevTools, mobile-mcp, and other stateful stdio servers
  • Auto-start daemon on first call to maintain connections
  • "lifecycle": "keep-alive" to opt in/out per server
  • MCPORTER_KEEPALIVE environment variable

Ephemeral servers:

  • Ad-hoc STDIO/HTTP targets
  • All others unless explicitly configured for keep-alive
