Overview

Description from the maker (original English)

Check an MCP Registry listing before you publish: README mcp-name line, server.json, name.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

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.

The maker has not listed install details in the registry. See the maker’s README below.

What it can do

Runs on your computer; the tool list appears in your AI app after you install it.

Compared with others in Otheri

  • More stars than 0% of the other 32537 servers in this category
  • Published to the registry more recently than 93% of the other 32537 servers in this category
  • Basic checks equal to or better than 100% of the other 32537 servers in this category

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is Rust MCP Preflight 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 (0.1.2) reached the registry 2 days ago.

Which apps can use it?

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

What can I use instead?

Rust MCP Preflight

Check an MCP Registry listing before you publish it.

mcp-publisher validate checks the shape of server.json. It doesn't check that the registry will accept your package: that only happens at mcp-publisher publish, after the crate version is already on crates.io and can't be changed. Rust MCP Preflight runs those checks first.

  • The README line. Fetches the README crates.io serves for the exact crate version and looks for mcp-name: , matched the way the registry matches it (ported from the registry's own validator). Catches the line hidden in an HTML comment (crates.io strips comments), the line glued to the next word, and a near miss such as the wrong case.
  • server.json. The rules mcp-publisher publish applies: $schema, the server name, and for every package exact versions (no latest, no ranges), the transport and no spaces in the identifier. For cargo packages also the crate version, no fileSha256 and registryBaseUrl. Plus warnings for runtimeHint, mismatched versions, and placeholders left over from mcp-publisher init.
  • The server name. The rules publish applies, whether it's already listed, and which login its namespace needs (including GitHub organizations, which login github can't publish to yet).

It only reads: crates.io, the official registry and the GitHub users API. It publishes nothing and needs no keys.

Install

Prebuilt, in seconds (needs cargo-binstall):

cargo binstall rust-mcp-preflight

From source (compiles, a few minutes the first time):

cargo install rust-mcp-preflight

Or download the binary for your platform from the release assets: Linux (x86_64, aarch64), macOS (Intel, Apple silicon) and Windows (x86_64), each with a .sha256 file. Prebuilt binaries start with 0.1.2; for an earlier version, cargo binstall falls back to QuickInstall or compiling from source.

Use it from a terminal or CI

rust-mcp-preflight server.json

It prints one line per check. It exits 0 when ready, 1 if anything fails, and 2 if the file can't be read:

Preflight: server.json

PASS name "io.github.VoidNullable/lific" is a valid server name PASS packages[0]: cargo crate "lific" WARN VoidNullable is a GitHub organization: mcp-publisher login github can't publish to org namespaces yet (registry #1468). ... INFO already listed: latest 2.11.1 (active). Your next publish needs a new version number PASS README of lific 2.11.1 on crates.io contains mcp-name: io.github.VoidNullable/lific

Ready: no failures, 1 warning(s).

Use it from an MCP client

claude mcp add preflight -- rust-mcp-preflight
{ "mcpServers": { "preflight": { "command": "rust-mcp-preflight" } } }
ToolWhat it checks
preflightEverything below, from the text of server.json
check_server_jsonThe publish rules (offline)
check_readmeThe mcp-name: line in one crate version's README on crates.io
check_nameThe name's publish rules, listing and namespace login

A result with a FAIL has isError set, like the CLI's exit 1: the check ran, and the listing isn't ready.

Where it fits

The order is: cargo publish (with the line in the README), then rust-mcp-preflight server.json, then mcp-publisher login github and mcp-publisher publish.

The full walk-through: Listing a Rust MCP server in the official MCP Registry.

The README check and the crates.io rules are for cargo packages. Other package types (npm, PyPI, mcpb and so on) get the shared rules, and their registry's own checks are listed as not run.

If crates.io or the README can't be reached, the README counts as not checked and the result is a failure, so a CI run never passes on a README it didn't see.
