E2b (e2b-dev) MCP Server
e2b-mcp-server
PyPI
v0.1.1
Published by e2b-dev — 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.
E2B MCP Server
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 − 3.6 = 96. What the published surface and source actually contain:
| Points | What was found | Category |
|---|---|---|
| −3.6 | Near-miss of exa-mcp-server MTC-SUP-005 | supply-chain |
2. Client adoption risk — 96 − 7 = 89. 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 |
|---|---|
| −6 | capability blast radius (high) — client exposure if the model is manipulated |
| −1 | publisher verification (public source) — no provenance, but the source is public and inspectable |
Capability observations and info notes are shown under Findings but never scored.

Findings 3
high Tool "run_code" exposes command/code executionMTC-CAP-001
Tool "run_code" appears to run shell commands or evaluate code (keyword "run_code" in tool name). Arbitrary execution driven by model input is one of the most dangerous MCP capabilities; combined with any untrusted input it becomes RCE.
Fix: Sandbox execution, allowlist commands/arguments, and never pass model output to a shell unescaped.
Location: tool run_code
medium Near-miss of exa-mcp-server (edit distance 2)MTC-SUP-005
"e2b-mcp-server" is edit-distance 2 from the package "exa-mcp-server". Verify this is the intended package.
Fix: Confirm you meant "exa-mcp-server". Install packages only from their documented, official name.
Location: package e2b-mcp-server
low Mutating tool "run_code" declares no destructiveHintMTC-CAP-005
Tool "run_code" can mutate/egress but declares no destructiveHint. Clients that don't default to spec-safe behavior may not prompt before running it.
Fix: Declare accurate annotations, and gate destructive tools on user confirmation regardless.
Location: tool run_code
Tools 1
Each tool and what it can reach — statically extracted from the published source.

What this scan could not see
- Tools were statically extracted from the published source (1 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 |
|---|---|---|---|---|
v0.1.1 latest |
B 89/100 | 3 | 1.13.0 | 2026-08-25 |
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.
