Serper (pipeworx) MCP Server

@pipeworx/mcp-serper npm v0.1.0

Published by @pipeworx — no publish provenance, so origin is unverified, but the source is public: the repository link below is self-declared yet readable, so you can inspect the code before adopting it.

Serper MCP — wraps the Serper Google Search API (serper.dev)

Trust

B · 80/100

Adoption risk for you: the threat score, then adjusted down for blast radius, publisher verification and how much the scan could see. Deterministic; every point is auditable.

Capability

Minimal

Blast radius if it went rogue — what the server’s tools could reach. Independent of trust.

Coverage

Source

How much the scan could actually inspect. Shallow coverage is stated, never hidden.

B Why this grade threat 81 − adoption risk = 80/100

The grade answers one question — how safe is this server for you to adopt — so it is computed in two auditable stages. Nothing below is an opinion or an LLM's guess; every line is a real term the deterministic engine applied, and the same input always yields the same number.

1. Threat score — 100 − 18.6 = 81. What the published surface and source actually contain:

Points	What was found	Category
−18.6	Near-miss of @sentry/mcp-server ×2 MTC-SUP-005	supply-chain

2. Client adoption risk — 81 − 1 = 80. Three small, subtract-only factors that reflect your risk in adopting it — a clean scan proves less on a powerful, unverified or barely-inspectable package, so the grade says so plainly:

Points	Adoption-risk factor
−1	publisher verification (public source) — no provenance, but the source is public and inspectable

Findings 2

high Near-miss of @sentry/mcp-server (edit distance 1)MTC-SUP-005

"@pipeworx/mcp-serper" is edit-distance 1 from the high-traffic package "@sentry/mcp-server". Verify this is the intended package.

Fix: Confirm you meant "@sentry/mcp-server". Install packages only from their documented, official name.

Location: package @pipeworx/mcp-serper

medium Near-miss of @heroku/mcp-server (edit distance 1)MTC-SUP-005

"@pipeworx/mcp-serper" is edit-distance 1 from the package "@heroku/mcp-server". Verify this is the intended package.

Fix: Confirm you meant "@heroku/mcp-server". Install packages only from their documented, official name.

Location: package @pipeworx/mcp-serper

What this scan could not see

No tools were enumerated, so prompt-injection, capability and toxic-flow analysis had no tool surface to inspect. To grade a package’s real runtime tools, scan the running server: --command "npx -y <package>".

Versions 1

Scan history per published version. The engine is deterministic — the same version always yields the same score, so a changed score means the package itself changed.

Version	Score	Findings	Engine	Scanned
`v0.1.0` latest	B 80/100	2	1.13.0	2026-09-07

Embed this score

Show this server's live Trust Score in your README, docs or website. The badge is served straight from the registry and updates automatically after every rescan — no API key needed. It links back to this page, so anyone who sees the grade can also read the findings behind it instead of taking a number on faith.

Verify this score yourself

The score above is reproducible: the same package version always yields the same result. Run it locally or over the free API — no account, no LLM, fully deterministic.
