X (afikrim) MCP Server
mcp-server-x
PyPI
v0.3.0
Published by afikrim — 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.
An MCP server that scrapes X (formerly Twitter) using a stealth Patchright browser, exposed over FastMCP.
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 − 5.4 = 95. What the published surface and source actually contain:
| Points | What was found | Category |
|---|---|---|
| −5.4 | Near-miss of @sentry/mcp-server ×2 MTC-SUP-005 | supply-chain |
2. Client adoption risk — 95 − 7 = 88. 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 Shell/command execution in server code (x_mcp_server/install.py)MTC-SRC-002
In the server's implementation (`x_mcp_server/install.py:106`): Spawning a shell/process is command-execution capability; with unsanitized tool input it is command injection / RCE. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.
Evidence: ude"): result = subprocess.run( ["claude", "mcp", "add-json", SERVER_NAME, json.dumps(entry), "--sco
Fix: Review this call path: confirm it never receives unsanitized tool input, constrain it, or remove it. Treat a server whose code reaches these sinks as high-capability regardless of what its tools claim.

medium Near-miss of @sentry/mcp-server (edit distance 2)MTC-SUP-005
"mcp-server-x" is edit-distance 2 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.

Tools 1
Each tool and what it can reach — statically extracted from the published source.
check_authno sensitive capability
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 |
|---|---|---|---|---|
v0.3.0 latest |
B 88/100 | 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.
