What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs on your computer
Transport: stdio
Category: Other

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
The registry lists no key to fill in.

You need

npmNode.js installed (for the npx command)

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "better": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-better"
      ]
    }
  }
}

Run this in your terminal

claude mcp add better -- npx -y mcp-better

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "better": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-better"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "better": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "mcp-better"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is mcp-better safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.5.0) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Rust, Node.js on your computer.

What can I use instead?

mcp-better — built for 7/28

NONE | GOOD | [BETTER] | BEST

Textbook for AGENTS.md on that scale — honest modern MCP at the BETTER step. *(protocol 2026-07-28 — the modern MCP release)*

the book is the app is the book

AAIF-verified modern MCP textbook that runs. Rust · rmcp 3.0.x (lock 3.0.1, Tier 1 assessed) · Discover · stamped list cache. Book: textbook/ — what · why · how · doctrine. App: this binary + smokes. Lesson after lesson, version after version — knowledge compounds.

BEST (BETTER plus project.faf that is resident and used: persistent project context that authors the agent files) lives at [faf.one/agents](https://faf.one/agents), one hop up from this textbook.

Dual-package (optional)

We are Cargo. Install is cargo install. npx is a try path. We do not offer npm install as an option.

→ Why dual-package — positioning + FAQ → Full guide (how) — lockstep, publish order, OIDC, score + wire

Skills over MCP (optional · textbook)

One Agent Skill (mcp-better-lab) on the same process as tools:

→ docs/SKILLS-OVER-MCP.md — extension · skills/list · skills/get · digests

What is 7/28?

Name	What it is
7/28	The era name — speakable, brandable. “Built for 7/28.”
2026-07-28	The protocol version — the date string on the wire / in SDKs.

7/28 is a great name. 2026-07-28 is a date. Humans say 7/28. Machines negotiate `2026-07-28`.

What to expect

Built for 7/28 — not bolted onto a legacy server (official rmcp 3.0.x / Tier-1 assessed cut).
Honest surface — transport and capabilities match docs and CI.
Roadmap expands the era — versions add road; they do not “become” 7/28 later.

Version	Lesson (the version is the lesson)
v0.1	7/28 over stdio — Discover, stamped `ttlMs` / `cacheScope`, stable order, `health` + `echo`
v0.2	Same 7/28 era + Streamable HTTP road + routing headers (`Mcp-Method` / `Mcp-Name`)
v0.3	Same era + deeper correctness — multi-list + restart-order smokes · `mcp-worse` contrast
v0.4	Same era + dual package — cargo + npm shim · `npx mcp-better` with no Rust toolchain
v0.4.3	Same era + `confirm_echo` MRTR (SEP-2322) + Agent Skills (`mcp-better-lab`) — see `docs/MRTR-CONFIRM-ECHO.md` · `docs/SKILLS-OVER-MCP.md`
v0.4.4	Same era + book matches 0.4.3 wire — no new tool · catalogs named `health` → `echo` → `confirm_echo`
v0.5	Same era + matching client completes MRTR — `mrtr-client` finishes `confirm_echo`

What BETTER means

Protocol honesty — claim 7/28 / 2026-07-28 only for surfaces you implement and test.
Discover-compatible — clients should use ClientLifecycleMode::Discover (or Auto → 7/28), not only legacy initialize.
List cache stamps — tools/list returns positive ttlMs and cacheScope (static catalog → public). SDK defaults are unstamped.
Stable tool order — same process, same order across N list calls.
Transports — stdio (default) and Streamable HTTP (--http) in the same 7/28 era.

Quickstart (≤10 min)

Path	What it is
`cargo install mcp-better`	The install — we are Cargo. crates.io, native binary on PATH.
`npx mcp-better`	Suggested try — no Rust, no compile. Not the install.
npm	A published shim so `npx` / some hosts can start the same binary. We do not offer `npm install` / `npm i -g`.

Try (suggested) — `npx`

# No Rust toolchain. Downloads the native binary from GitHub Releases.

npx mcp-better --help npx mcp-better

From source / crates.io (Rust 1.85+)

git clone https://github.com/Wolfe-Jam/mcp-better.git

cd mcp-better cargo build --bins cargo test cargo run --example stdio-client

louder 0.3 smokes (build --bins first; or: bash scripts/ci.sh)

MCP_BETTER_BIN="$(pwd)/target/debug/mcp-better" cargo run --example order-restart-smoke MCP_BETTER_BIN="$(pwd)/target/debug/mcp-better" \ MCP_WORSE_BIN="$(pwd)/target/debug/mcp-worse" \ cargo run --example contrast-smoke MCP_BETTER_BIN="$(pwd)/target/debug/mcp-better" cargo run --example http-smoke

0.5 matching client (completes confirm_echo)

MCP_BETTER_BIN="$(pwd)/target/debug/mcp-better" cargo run --example mrtr-client

Install (crates.io) — stdio default (Cursor / Claude Desktop):

First `cargo install` compiles Rust deps once (often 100+ units — rmcp / tokio / …, not 100 tools of ours). One-time; then the binary is instant. To skip that compile, try with npx mcp-better (above) — that is not the install.

cargo run --release

install from crates.io — first hit compiles deps once (see above):

cargo install mcp-better --version 0.5.0 mcp-better --help

optional lying companion (teaching only — not for hosts):

cargo install mcp-better --version 0.5.0 --bin mcp-worse

Streamable HTTP (local demo only — see SECURITY.md):

cargo run --release -- --http

http://127.0.0.1:8787/mcp

MCP_BETTER_HTTP_ADDR=127.0.0.1:9000 mcp-better --http

Transport selection (CLI wins over env):

How	Value
CLI	`mcp-better` (stdio) · `mcp-better --http` · `mcp-better --stdio`
Bare args	`http` / `stdio` (same meaning as flags)
Env	`MCP_TRANSPORT` or `MCP_BETTER_TRANSPORT` → `stdio` \	`http` (`MCP_TRANSPORT` first if both set)
HTTP bind	`MCP_BETTER_HTTP_ADDR` — default `127.0.0.1:8787`. Do not use `0.0.0.0` unless you accept an unauthenticated open endpoint.

Tools

Tool	Purpose
`health`	Liveness — status, version, protocol. No side effects. Not a k8s probe contract.
`echo`	Pure demo — returns `message` unchanged.
`confirm_echo`	Textbook MRTR (SEP-2322) — echo after mid-call confirm · sealed `requestState`.

Protocol claims (v0.5.0 — same 7/28 era · matching client completes MRTR)

Surface	Status
Era / protocol	7/28 · negotiated `2026-07-28` (Discover preferred)
Transport	stdio (default) · Streamable HTTP (`--http`)
HTTP mode	Stateless for 7/28 · `json_response` · local Host guards
Routing headers	Streamable HTTP POSTs use `Mcp-Method` and `Mcp-Name` when naming a tool (SEP-2243); `http-smoke` asserts this happy path
Capabilities	tools · resources (skill docs) · experimental skills extension
List cache	`ttlMs=60000`, `cacheScope=public`, order `health`→`echo`→`confirm_echo` (restart-stable)

| MRTR (optional) | `confirm_echo` — mid-call confirm · sealed requestState · matching client `mrtr-client` · docs/MRTR-CONFIRM-ECHO.md | Skills (optional) | `mcp-better-lab` · skills/list · digests · docs/SKILLS-OVER-MCP.md | | Lying companion | `mcp-worse` — unstamped + reversed order (contrast-smoke only) | | OAuth / tasks | out of hero |

Textbook

The book is the app is the book — textbook/ (Season 1 · doctrine).

Start: textbook/README.md → lab Ch 09.

Non-goals (GOOD-era habits we refuse)

Shipping unstamped list results while claiming 7/28 modernity
Requiring project.faf or any BEST tooling on this repo’s main branch
Treating stdio as “not real 7/28” — stdio is a first-class 7/28 transport
FAF install tax in the AAIF lede — this repo is protocol textbook, not a FAF product

Registry identity

MCP Registry name: mcp-name: io.github.Wolfe-Jam/mcp-better
Dual packages (same version, both stdio):
registryType: cargo · identifier: mcp-better · crates.io
registryType: npm · identifier: mcp-better · registry.npmjs.org (Node shim downloads the native binary from GitHub Releases — no Rust on the host)
Package transport in `server.json` is stdio only — by design. Hosts spawn via cargo install / npx mcp-better on stdio. Streamable HTTP (--http) is an opt-in local demo in the same binary and the same 7/28 era; it is not a Registry remote package. Discover it in this README and --help.

See server.json. Not one.faf/*.
