@axiestudio/tool

Zero-dependency fetch wrappers that replace MCP servers for AI agent workflows. Every tool shares the same invoke(toolName, args) interface — no installation, no daemon, no config. Just import and call.

Works with Node.js (18+), Bun, Deno, and any runtime that supports fetch and ES modules. Use from Python, Go, or any language via subprocess.

Inspired by Mario Zechner's "What if you don't need MCP?" — the idea that plain fetch wrappers outperform protocol-heavy MCP servers for most AI agent use cases.

Install

npm install @axiestudio/tool   # or bun add / pnpm add / yarn add

Or just copy the .js files you need — they have zero npm dependencies.

Core tools are the 52 .js files in the root. They use only the built-in fetch() API (available in Node 18+, Bun, Deno). No npm install required — copy the files and import.

Browser tools in browser/ connect to Chrome via CDP and require puppeteer-core (~2 MB, no bundled Chromium). Install only if you need browser automation.

Interactive CLI (bin/cli.js) provides a full-screen terminal UI. It requires ink and react. These are listed as optionalDependencies — skip them if you only use the tools programmatically.

Runtime Compatibility

# Node.js (18+)
node --input-type=module -e "import { invoke } from './npm.js'; ..."

# Bun
bun -e "import { invoke } from './npm.js'; ..."

# Deno
deno run --allow-net npm.js

# Python (via subprocess)
import subprocess
result = subprocess.run(["node", "--input-type=module", "-e",
    "import { invoke } from './npm.js'; const r = await invoke('search', { query: 'hono' }); console.log(JSON.stringify(r));"
], capture_output=True, text=True)
print(result.stdout)

Usage

Docs tools (48 tools — all share the same interface)

All documentation tools expose three commands: get-index, get-page, and search-docs.

import { invoke } from "@axiestudio/tool/hono-docs"; // swap for any docs tool

// List all available doc pages
const { index }    = await invoke("get-index");

// Fetch a specific page as Markdown
const { markdown } = await invoke("get-page", { path: "/docs/getting-started" });

// Search across all docs
const { result }   = await invoke("search-docs", { query: "middleware" });

This same pattern works for all 48 docs tools:

import { invoke } from "@axiestudio/tool/react-docs";
import { invoke } from "@axiestudio/tool/vite-docs";
import { invoke } from "@axiestudio/tool/prisma-docs";
import { invoke } from "@axiestudio/tool/stripe-docs";
// ... any of the 48 docs tools

Note: cloudflare-docs has a slightly different interface — it uses list-products instead of get-index, and search-docs takes a product parameter. See below.

Context7 — live library docs (two-step)

import { invoke } from "@axiestudio/tool/context7";

// Step 1: resolve library ID (always required)
const id = await invoke("resolve-library-id", { libraryName: "hono" });

// Step 2: fetch docs for a topic
const docs = await invoke("get-library-docs", { libraryId: id, topic: "middleware" });

Set CONTEXT7_API_KEY for higher rate limits. Works without it on the free tier.

Cloudflare Docs

import { invoke } from "@axiestudio/tool/cloudflare-docs";

const { products } = await invoke("list-products");
const { markdown } = await invoke("get-page", { path: "/workers/runtime-apis/kv/" });
const { result }   = await invoke("search-docs", { product: "d1", query: "migrations" });

npm Registry

import { invoke } from "@axiestudio/tool/npm";

const results  = await invoke("search", { query: "hono middleware" });
const readme   = await invoke("get-readme", { packageName: "drizzle-orm" });
const info     = await invoke("get-package-info", { packageName: "better-auth" });
const versions = await invoke("get-versions", { packageName: "react" });
const stats    = await invoke("get-downloads", { packageName: "hono" });
const deps     = await invoke("get-dependencies", { packageName: "drizzle-orm" });

GitHub

import { invoke } from "@axiestudio/tool/github";

const { content }  = await invoke("get-file", { owner: "honojs", repo: "hono", path: "src/index.ts" });
const { entries }  = await invoke("list-dir",  { owner: "honojs", repo: "hono", path: "src" });
const { items }    = await invoke("search-code", { query: "DurableObject alarm in:file language:ts" });
const { releases } = await invoke("get-releases", { owner: "cloudflare", repo: "workers-sdk" });
const info         = await invoke("get-repo-info", { owner: "honojs", repo: "hono" });
const diff         = await invoke("compare-tags", { owner: "honojs", repo: "hono", base: "v4.0.0", head: "v4.1.0" });

Browser Automation (CDP)

Minimal Puppeteer Core scripts for scraping and frontend testing. Requires Chrome + puppeteer-core.

# Install the dependency (only needed for browser tools)
npm install puppeteer-core

# Start Chrome on port 9222
node browser/start.js        # or: bun browser/start.js

# Navigate, screenshot, extract text
node browser/nav.js https://example.com
node browser/screenshot.js
node browser/get-text.js '#main'

# Form interaction
node browser/fill.js '#email' user@example.com
node browser/pick.js "Click the submit button"

# Utilities
node browser/eval.js 'document.title'
node browser/wait.js '.loaded' 10
node browser/links.js --json
node browser/cookies.js --curl
node browser/scroll.js bottom --wait 2

All browser scripts use node as the shebang but work equally with bun. If puppeteer-core is not installed, you get a friendly error message with install instructions instead of a cryptic module-not-found crash.

See browser/README.md for the full reference.

Interactive CLI

npx @axiestudio/tool           # interactive explorer (all 52 tools)
npx @axiestudio/tool init      # generate config for your AI agent

The interactive explorer lets you browse all 52 tools, pick commands, fill in parameters, and see results — all from the terminal. The init wizard generates a skill file for your AI agent setup.

Design Philosophy

Zero dependencies for core tools — each tool is a single .js file using only the fetch() API built into modern runtimes.
Runtime-agnostic — works with Node.js 18+, Bun, Deno, or any ES module runtime with fetch. Use from Python/Go/Rust via subprocess.
Same interface everywhere — invoke(toolName, args) works the same across all 52 tools.
No MCP, no daemons — just plain HTTP fetch calls. No protocol overhead.
Drop-in for agents — copy the .js files next to your project and import directly. No npm required.
Optional layers — browser tools need puppeteer-core, interactive CLI needs ink/react. Skip what you don't need.

Environment Variables

Variable	Used by	Purpose
`CONTEXT7_API_KEY`	`context7.js`	Bearer token for higher rate limits

All other tools work without any API keys.

Testing

# Unit tests (810 tests, offline — no network)
node --test test/*.test.mjs

# Live API smoke tests (hits every tool's real endpoint)
node test/_live_test_all.mjs
