Notion (snickery) MCP Server
notion-mcp
PyPI
v0.1.0
Published by snickery — 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.
MCP server for Notion: pages, databases, markdown, comments, and a full file pipeline
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 − 31.5 = 69. What the published surface and source actually contain:
| Points | What was found | Category |
|---|---|---|
| −31.5 | Self-contained exfiltration primitive: "notion_download_file" MTC-FLOW-001 | exfiltration |
2. Client adoption risk — 69 − 11 = 58. 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 |
|---|---|
| −10 | capability blast radius (critical) — client exposure if the model is manipulated |
| −1 | publisher verification (public source) — no provenance, but the source is public and inspectable |
Grade capped: a critical finding is present → grade capped at D. A hard gate overrides the point total — no amount of clean surface buys back a confirmed catastrophe.
Capability observations and info notes are shown under Findings but never scored.

Findings 3
critical Self-contained exfiltration primitive: "notion_download_file"MTC-FLOW-001
Tool "notion_download_file" holds all three trifecta roles by itself (untrusted-input + sensitive-source + external-sink). A single call can pull attacker-controlled content, read private data, and exfiltrate it — no composition required.
Fix: Split responsibilities across separate, individually-consented tools; never combine untrusted input, secret reads, and egress in one tool.
Location: flow notion_download_file
high Read-and-egress in one tool: "notion_search_pages"MTC-FLOW-003
Tool "notion_search_pages" can both read sensitive data and send data to an external destination. Even without an explicit untrusted-input leg, this is a single-call data-exfiltration path if the model is ever manipulated.
Fix: Separate reading from sending; require explicit user confirmation before egress of file/secret contents.
Location: flow notion_search_pages
high Read-and-egress in one tool: "notion_describe_database"MTC-FLOW-003
Tool "notion_describe_database" can both read sensitive data and send data to an external destination. Even without an explicit untrusted-input leg, this is a single-call data-exfiltration path if the model is ever manipulated.
Fix: Separate reading from sending; require explicit user confirmation before egress of file/secret contents.
Location: flow notion_describe_database

Toxic flows 3
Cross-tool combinations that form a data-exfiltration primitive (untrusted input → sensitive source → external sink).
What this scan could not see
- Tools were statically extracted from the published source (44 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 |
|---|---|---|---|---|
v0.1.0 latest |
F 58/100 | 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.
