The defect, measured

@wave-av/mcp-server@0.2.0 is the current latest on npm, and it reports the wrong version over its own protocol. Reproduced against the real registry tarball (sha1 verified against the registry's published dist.shasum, 6b83eb94…):

$ curl -sSfL -o mcp-0.2.0.tgz https://registry.npmjs.org/@wave-av/mcp-server/-/mcp-server-0.2.0.tgz
$ shasum -a 1 mcp-0.2.0.tgz     -> 6b83eb94a78e4c93a7ffd6c90814f63d21330d0e   (matches registry)
$ node -p "require('./pkg/package.json').version"          -> 0.2.0
$ grep -oE 'version: *"[0-9]+\.[0-9]+\.[0-9]+"' pkg/dist/index.js  -> version: "0.1.0"

Over the actual MCP handshake:

initialize: wave-mcp-server 0.1.0 (protocol 2025-06-18)

A second wrong surface in the same artifact was not in the original report and is found here: the outbound User-Agent is also wave-mcp-server/0.1.0.

What was already fixed, and what was still missing

The source cause is already fixed on main by 8063eb4 / #90: src/version.ts derives PKG_VERSION from package.json via createRequire(import.meta.url), and serverInfo, the User-Agent, --version and the --help banner all consume it. package.json is 0.2.1. That fix is not live — npm latest is still 0.2.0, so installed copies stay wrong until 0.2.1 publishes.

What was missing is the gate. Two holes:

  1. scripts/smoke-mcp.mjs prints serverInfo.version and asserts nothing. Run against the published 0.2.0 artifact it emits initialize: wave-mcp-server 0.1.0 and exits 0. Verified:
$ node scripts/smoke-mcp.mjs node_modules/@wave-av/mcp-server/dist/index.js
initialize: wave-mcp-server 0.1.0 (protocol 2025-06-18)
tools/list: 18 tools
$ echo $?
0

That is a green check measuring nothing on exactly the surface that shipped broken.

  1. smoke-install.yml does assert --version against package.json, but --version was added after the defect. serverInfo, the User-Agent and the banner had no assertion anywhere.

The gate

scripts/check-version-surfaces.mjs — no new dependency, no package.json change. It asserts equality between package.json's version and every place the package states its own version, measuring the built artifact over its real interfaces rather than reading the source:

# Surface How it is measured
1 serverInfo.version real stdio JSON-RPC initialize
2 serverInfo.name same handshake
3 --version stdout
4 --help banner regex-extracted, compared for equality
5 User-Agent captured off the wire from a 127.0.0.1 listener
6 src/**/*.ts no hardcoded semver literal outside a documented allowlist

Design points worth review:

  • The User-Agent is captured off the wire, not grepped out of the bundle. The script binds a loopback HTTP server on an ephemeral port, points WAVE_BASE_URL at it, drives a real tools/call, and reads the inbound user-agent header. Nothing but 127.0.0.1 is contacted; the dummy key is a non-functional literal and is never printed.
  • The banner is compared for equality on an extracted capture, not grepped for the expected string. A substring grep passes when the banner is missing entirely.
  • An unmeasurable surface fails. Every arm that cannot run reports an error rather than skipping, including "no request reached the listener" and "no src/ to scan".
  • Surface 6 catches the defect class, not the value. Correcting a literal to today's number just reproduces the bug at the next release.
  • Stale-artifact guard. When gating an installed copy, the script asserts that copy's version equals the repo's — otherwise a stale tarball would be measured against its own stale manifest and agree with itself.

A false positive, verified rather than "fixed"

The first run of surface 6 flagged src/auth.ts:40:

src/auth.ts:40 return hostname === "localhost" || hostname === "127.0.0.1" || ...

127.0.0.1 is an IPv4 address whose first three octets are shaped exactly like a semver. It is not a version at all, so allowlisting it would have been a false entry that also blinds the scan to a real literal added to that line later. The pattern was tightened instead — the quoted form is anchored to both quotes, so a fourth dotted octet rejects the match while "0.1.0" still matches. The allowlist ships empty, documented for the class that genuinely belongs there: a config-FORMAT or wire-protocol version, which must not track the package version. This repo's MCP protocol version (2025-06-18) is date-shaped and does not match the pattern.

Proof: red on seeded divergence, green when restored

Each arm was drilled independently, so a single seed proves that arm alone.

Seed A — src/server.ts serverInfo hardcoded to "0.1.0" (exactly what 0.2.0 shipped):

measured:
  ok   serverInfo.name = wave-mcp-server
  ok   --version = 0.2.1
  ok   --help banner = 0.2.1
  ok   User-Agent (on the wire) = wave-mcp-server/0.2.1

VERSION-SURFACE GATE FAILED:
  ::error::serverInfo.version: MCP initialize reports "0.1.0", package.json says "0.2.1"
  ::error::source scan: hardcoded version literal(s) under src/ ...
    src/server.ts:14 version: "0.1.0",
GATE exit=1

Seed B — src/auth.ts User-Agent hardcoded to wave-mcp-server/0.1.0:

measured:
  ok   serverInfo.version = 0.2.1
  ok   serverInfo.name = wave-mcp-server
  ok   --version = 0.2.1
  ok   --help banner = 0.2.1

VERSION-SURFACE GATE FAILED:
  ::error::User-Agent: wire header is "wave-mcp-server/0.1.0", expected "wave-mcp-server/0.2.1"
  ::error::source scan: ...
    src/auth.ts:108 "User-Agent": `wave-mcp-server/0.1.0`,
GATE exit=1

Only the seeded surface goes red in each case — the wire capture is genuinely independent of the handshake arm.

Restored (git checkout -- src/auth.ts src/server.ts, rebuild):

measured:
  ok   serverInfo.version = 0.2.1
  ok   serverInfo.name = wave-mcp-server
  ok   --version = 0.2.1
  ok   --help banner = 0.2.1
  ok   User-Agent (on the wire) = wave-mcp-server/0.2.1
  ok   source scan = 14 .ts files, 0 hardcoded semver literals

VERSION-SURFACE GATE PASSED: all 6 surfaces report 0.2.1
GATE exit=0

Against the published 0.2.0 artifact — the gate pointed at the tarball that actually shipped the bug:

::error::artifact freshness: installed copy is 0.2.0 but the repo is 0.2.1 — stale tarball under test
::error::serverInfo.version: MCP initialize reports "0.1.0", package.json says "0.2.0"
::error::--version: prints "", package.json says "0.2.0"
::error::--help banner: no "wave-mcp-server <version>" banner line found in --help output
::error::User-Agent: wire header is "wave-mcp-server/0.1.0", expected "wave-mcp-server/0.2.0"
GATE exit=1

Against a fresh clean-room install of the fixed build (npm packnpm install into a throwaway project outside the workspace) — this is the arm that proves the runtime package.json walk resolves from a node_modules layout and not only from the repo tree:

package under test : /tmp/mcp-fresh/node_modules/@wave-av/mcp-server
VERSION-SURFACE GATE PASSED: all 6 surfaces report 0.2.1

CI

.github/workflows/version-surfaces.yml, on pull_request and push: main, Node 20 and 22, permissions: contents: read, action SHAs pinned to the same versions this repo already uses. Two arms — built tree, and packed + clean-room-installed tarball. No secret is read and no token is used. No ${{ github.event.* }} interpolation appears in any run: block.

npm run lint and npm run type-check both exit 0 on this branch, unchanged from main.

Verified on this PR's own CI run (33879280823) — both arms executed and measured on Node 20 and Node 22, not skipped:

Version surfaces (built tree)
  package under test : /home/runner/work/mcp-server/mcp-server
  ok   serverInfo.version = 0.2.1
  ok   serverInfo.name = wave-mcp-server
  ok   --version = 0.2.1
  ok   --help banner = 0.2.1
  ok   User-Agent (on the wire) = wave-mcp-server/0.2.1
  ok   source scan = 14 .ts files, 0 hardcoded semver literals
  VERSION-SURFACE GATE PASSED: all 6 surfaces report 0.2.1

Version surfaces (installed artifact)
  package under test : /home/runner/work/_temp/verspace/node_modules/@wave-av/mcp-server
  ok   serverInfo.version = 0.2.1
  ...
  ok   User-Agent (on the wire) = wave-mcp-server/0.2.1
  VERSION-SURFACE GATE PASSED: all 6 surfaces report 0.2.1

The loopback User-Agent capture working on a hosted runner is the notable one — it confirms the ephemeral-port listener and the tools/call round trip are not dependent on a local environment.

Scope — deliberately untouched

Every natural place to put this is owned by an open PR, so nothing shared is edited:

Verified / not verified

  • Verified: every transcript above was produced in an isolated worktree off origin/main (f482251), Node v22.14.0. Registry facts read from registry.npmjs.org directly.
  • Verified on real CI: run 33879280823, both arms, Node 20 and Node 22 (transcript above).
  • Not measured: the gate has not been observed going RED on GitHub Actions — the seeded-divergence transcripts above were produced locally. The failure path is the same process.exit(1) the workflow surfaces, but a seeded-red CI run is not part of this PR.
  • This PR does not publish, tag, or bump a version.

Rollback

git revert f850e13. Two new files, no dependency, no runtime code touched — reverting removes the gate and changes nothing the package ships.

…rInfo, --version, banner, User-Agent)

Published @wave-av/mcp-server@0.2.0 answers the MCP initialize handshake with
serverInfo.version = "0.1.0". The source cause was fixed on main by 8063eb4
(src/version.ts derives PKG_VERSION from package.json), but nothing prevents
the regression from returning, and the existing smoke PRINTS serverInfo.version
without asserting it -- it exits 0 on the 0.1.0-reporting artifact.

Adds scripts/check-version-surfaces.mjs, which asserts equality between
package.json and every surface: serverInfo.version/.name over a real stdio
handshake, --version, the --help banner (extracted and compared for equality,
so a missing banner fails rather than passing), and the outbound User-Agent
captured off a 127.0.0.1 listener. Plus a src/**/*.ts scan for hardcoded semver
literals -- the defect class, not the value.

Adds .github/workflows/version-surfaces.yml running it on PRs in two arms: the
built tree, and a packed + clean-room-installed tarball (different layout, and
only the second is what a consumer gets).

No package.json, smoke-install.yml, smoke-mcp.mjs or release.yml changes --
each is owned by an open PR.

Reviewer's Guide

This PR adds a six-surface version-consistency gate and CI workflow that validates both built and clean-room-installed artifacts across Node 20 and 22, preventing package.json drift from reaching MCP metadata, CLI output, banners, or wire-level User-Agent headers.

File-Level Changes

Change Details Files
Adds a reusable gate that validates all package-version surfaces against package.json through built-artifact interfaces.
  • Reads the expected version from the target package manifest and checks installed-artifact freshness against the repository.
  • Exercises MCP initialize to validate serverInfo.version and serverInfo.name.
  • Runs --version and --help, requiring exact version matches rather than substring presence.
  • Captures the outbound User-Agent from a loopback HTTP request driven through a real tools/call.
  • Scans TypeScript sources for hardcoded semver literals, with a documented allowlist and handling for IPv4 false positives.
  • Fails when any surface cannot be measured and reports GitHub Actions-compatible errors.
scripts/check-version-surfaces.mjs
Introduces CI coverage for both the repository build and the packaged clean-room installation across supported Node versions.
  • Runs on pull requests, pushes to main, and manual dispatch with read-only permissions.
  • Tests Node 20 and 22 with pinned checkout and setup actions.
  • Builds the project, runs the gate against the built tree, then packs and installs the artifact outside the workspace before rerunning the gate.
  • Uses npm caching, a timeout, and cancel-in-progress concurrency controls.

💡 Edge Case: AGENT regex could double-count a literal already matched by QUOTED

A line like "User-Agent": \wave-mcp-server/${PKG_VERSION}`,won't double-match since the value is a template expression, but a hardcoded literal such as"wave-mcp-server/0.1.0"will be reported twice — once by QUOTED (matching the whole quoted string's trailing digits) and once by AGENT (matchingwave-mcp-server/0.1.0). This only affects the cosmetic hit count/output formatting (the same line is pushed into hitstwice), not correctness of pass/fail, so it's low impact — worth a dedupe on${rel}:${i+1}` if the noise in failure output matters.

Adds comprehensive version-surface regression testing that verifies all six version reporting paths (serverInfo, --version, banner, User-Agent, source scan, artifact freshness) stay synchronized with package.json. The gate catches the defect class that shipped in 0.2.0 by measuring the built artifact over real interfaces rather than reading source. Consider deduplicating the QUOTED and AGENT regex patterns in the source scan to avoid double-counting hardcoded literals in the failure output.

The observation regarding the potential for double-counting literals is accurate. Because the checkSourceLiterals function iterates through both the QUOTED and AGENT regexes for every line, a hardcoded literal that matches both patterns will indeed be pushed into the hits array twice.

While this does not affect the correctness of the gate's pass/fail logic, it does create redundant noise in the failure output. Deduplicating the entries in the hits array before reporting them would improve the clarity of the error messages.

scripts/check-version-surfaces.mjs

while ((m = re.exec(line)) !== null) {
          const literal = m[1];
          const allowed = SEMVER_ALLOWLIST.some((a) => a.file === rel && literal.startsWith(a.literal));
          if (!allowed) hits.push(`${rel}:${i + 1} ${line.trim().slice(0, 120)}`);

📝 Summary

Summary by CodeRabbit

  • Chores
    • Added automated checks to ensure package version information remains consistent across command-line output, protocol responses, HTTP requests, and source code.
    • Added validation against both the built package and a freshly installed package artifact.
    • Added automated verification across supported Node.js 20 and 22 environments for pushes, pull requests, and manual runs.

Walkthrough

Added a version-surface checker and CI workflow. The checker validates package metadata, runtime interfaces, HTTP headers, and source literals against package.json. CI tests built and clean-installed artifacts on Node.js 20 and 22.

Add a timeout to run().

At Line 187, run() settles only after child-process exit. If --version or --help hangs, the gate never records the required measurement failure. CI then waits for the workflow timeout.

Proposed fix
 function run(args, env) {
   return new Promise((res) => {
     const child = spawn(process.execPath, [BIN, ...args], {
       stdio: ["ignore", "pipe", "pipe"],
       env: { ...process.env, ...env },
     });
     let out = "";
     let err = "";
+    let settled = false;
+    let timeout;
+    const finish = (result) => {
+      if (settled) return;
+      settled = true;
+      clearTimeout(timeout);
+      res(result);
+    };
     child.stdout.on("data", (c) => (out += c.toString()));
     child.stderr.on("data", (c) => (err += c.toString()));
-    child.on("exit", (code) => res({ code, out, err }));
+    timeout = setTimeout(() => {
+      child.kill("SIGKILL");
+      finish({ code: null, out, err: `${err}\ntimed out after ${RPC_TIMEOUT_MS}ms` });
+    }, RPC_TIMEOUT_MS).unref();
+    child.on("error", (error) => finish({ code: null, out, err: `${err}\n${error.message}` }));
+    child.on("exit", (code) => finish({ code, out, err }));
   });
 }

Require the --help banner on the first output line.

The checker documents this surface as the first line, but the /m flag lets ^ match after a newline. Output with an invalid leading line can therefore pass. Check only the first line and anchor the complete match.

Proposed fix
-  const m = out.match(/^wave-mcp-server\s+(\S+)/m);
+  const m = out.split(/\r?\n/, 1)[0].match(/^wave-mcp-server\s+(\S+)\s*$/);

Strip inline TypeScript comments before applying the semver checks. checkSourceLiterals() skips only lines that start with //, *, or /*. It still scans code lines with inline comments, such as const value = 1; // "9.8.7". QUOTED matches that text and can make the required workflow fail even though the literal is not runtime code.
