HTML page: https://policylayer.com/tools/knuckles-team-servicenow-api/servicenow-attachment ## Facts - Tool: `servicenow_attachment` - Server: Servicenow Api (`knuckles-team/servicenow-api`) — https://policylayer.com/tools/knuckles-team-servicenow-api.md - Homepage: https://github.com/Knuckles-Team/servicenow-api - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "servicenow_attachment", "arguments": {} } } ``` ## Why servicenow_attachment is rated Medium Attachment operations on ServiceNow are Write-category actions because they create or add new attachments/files to records. This is reversible (attachments can be removed) and does not delete data. Severity is medium due to potential for uploading malicious files or attaching sensitive content to records unintentionally, affecting data integrity and compliance. From the tool's own definition: "Tool name 'servicenow_attachment' suggests file attachment operations (create, upload, associate). Description is empty, limiting certainty. ServiceNow attachment operations typically involve creating or modifying attachments linked to records." ## Use case AI agents use servicenow_attachment to create or update resources in Servicenow Api, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Servicenow Api environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
