The evidence

Every deduction below names the artefact that produced it. Nothing on this page was executed: the source was read, never run, and no running server was contacted.

Code Safety

• cnnfag.go:139mcp-go-ssrf-nonliteral-url (medium/low)

  An outbound HTTP request is made to a URL that is not a literal. If any component is caller-supplied the server can be aimed at hosts it can reach and the caller cannot.

  // Get fetches the current Fear & Greed index from CNN.
  func Get(ctx context.Context) (Result, error) {
  	req, err := http.NewRequestWithContext(ctx, http.MethodGet, endpoint, nil)
  	if err != nil {
  		return Result{}, fmt.Errorf("building request: %w", err)

Auth Posture

• authentication_model

  stdio transport: the client launches the server as a subprocess, so the OS process boundary is the auth boundary — `03` §4 does not penalise absent auth here

• transport_security

  declared transport: stdio — launched as a subprocess by the client, so the security boundary is the client process, not a network port (`03` §4)

• secret_handling

  no committed credential found, and no environment variable with a credential-shaped name is read anywhere in the source

• authorization_granularity

  1 tool registration(s) detected — at or below `03` §4's threshold of 3, so there is no multi-tool surface to segregate

Maintenance

• recency

  last commit 39 day(s) before 2026-10-16

• issue_responsiveness

  lifetime median (0 issue(s) in the last 6 months, under `03` §5's floor of 3): 1509.3 day(s) to first maintainer comment

• release_cadence

  median release gap 0 days (by releases), last release 66 day(s) ago

• bus_factor

  sole maintainer

• repository_signals

  `03` §5 scores this by quartile WITHIN the server's category, which needs a distribution across every scanned server and so cannot be computed while scanning one. It is a post-pass over the crawl and that pass does not exist yet.

Transparency

• license

  LICENSE present with no SPDX-License-Identifier tag; identified as 'MIT' from its text

• readme_quality

  README.md: installation instructions (+25), configuration documented (+25), states what the server does in the first 200 words (+20)

• declared_scopes

  neither the README nor the MCP manifest documents what the server accesses or what side effects it has

• changelog

  no CHANGELOG in the fetched source. `03` §7's partial credit for tagged releases carrying release notes is not applied here — that needs the forge API, which this check does not call

• security_contact

  no SECURITY.md and no disclosure contact in the README, so a finder has no route to report a vulnerability privately
