Short explanation
Prior to version 1.8.7, the Dynatrace MCP Server create_dynatrace_notebook registration performs a persistent document-write action without invoking a human-approval gate [S0]. This allows callers to create tenant-visible notebooks containing attacker-controlled Markdown or DQL content [S0].
The lack of an approval gate and destructive hint annotations allows write actions to execute without operator consent, exposing tenants to embedded DQL execution risks [S0].
What should be done?
- Follow vendor advisories and security updates [S0]
- Review dynatrace-mcp releases [S0]
- Apply the available updates [S0]

Show the technical text from the sources
Dynatrace MCP Server is an MCP server for Dynatrace Observability. Prior to 1.8.7, the create_dynatrace_notebook registration in src/index.ts performs a persistent document-write action without calling requestHumanApproval, although the project's other write tools use that gate to obtain operator consent. A caller can create tenant-visible notebooks containing attacker-controlled Markdown or DQL content, and tenant users may later execute embedded DQL when opening the notebook. The tool also lacks a destructiveHint annotation that would signal its side effects to MCP clients. This issue is fixed in version 1.8.7.
