notion — agentic threat model
This agent integrates Claude Code with a Notion workspace via an MCP server, presenting significant data security risks due to its ability to read, write, and modify corporate databases and knowledge bases.

Scored with the canonical OWASP AIVSS formula (AIVSS calculator reference); agentic risk factors estimated from the agent’s described capabilities.
MAESTRO 7-layer threat model
Per-layer threats for this agent. Layers tagged “not certain from listing” are general, caveated commentary where the public description didn’t pin that layer.
Not certain from the listing — relies on Claude Code's underlying foundation model. Threats include prompt injection leading to unauthorized tool execution or data exfiltration via the Notion API.
Directly accesses, searches, and modifies Notion pages and databases. Highly vulnerable to indirect prompt injection if malicious content is stored in a Notion page that the agent reads, potentially poisoning the context window.
Uses an MCP (Model Context Protocol) server to expose tools for searching, creating, and updating documents. Risks include tool misuse, where the agent executes unintended database modifications or document deletions based on ambiguous instructions.
The MCP server runs locally or in a hosted environment authenticated to Notion. Security depends heavily on how the MCP server is hosted, how secrets (Notion API keys) are stored, and whether the execution environment is sandboxed.
Not certain from the listing — there is no mention of built-in logging, audit trails, or guardrails to monitor the actions the MCP server performs on the Notion workspace.
Authentication is handled via Notion API tokens. However, there is a risk of privilege creep if the integration token has full workspace access rather than scoped, least-privilege permissions.
Operates as a plugin within the Claude Code ecosystem. If Claude Code coordinates with other untrusted agents or plugins, malicious instructions could cascade to this Notion agent, leading to unauthorized data modification.
