@kajirita2002/esa-mcp-server npm v1.1.0

Published by @kajirita2002 — 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.

Trust

A · 90/100

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

Moderate

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.

A Why this grade threat 94 − adoption risk = 90/100

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 − 6.3 = 94. What the published surface and source actually contain:

Points	What was found	Category
−6.3	Near-miss of exa-mcp-server MTC-SUP-005	supply-chain

2. Client adoption risk — 94 − 4 = 90. 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
−3	capability blast radius (moderate) — client exposure if the model is manipulated
−1	publisher verification (public source) — no provenance, but the source is public and inspectable

Findings 1

medium Near-miss of exa-mcp-server (edit distance 1)MTC-SUP-005

"@kajirita2002/esa-mcp-server" is edit-distance 1 from the package "exa-mcp-server" (keyboard-adjacent slip). Verify this is the intended package.

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

Location: package @kajirita2002/esa-mcp-server

What this scan could not see

Tools were statically extracted from the published source (9 recovered), not enumerated from a running server. Tool-poisoning, Unicode-smuggling, capability and toxic-flow analysis ran on this inferred surface, but a mis-parsed registration could be missed or mis-attributed, so tool-derived findings are capped below “confirmed”. To grade the real runtime surface, 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
`v1.1.0` latest	A 90/100	1	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.
