# get_image Get image information Agent View of the PolicyLayer registry record for `get_image`. HTML page: https://policylayer.com/tools/1021143806-napcat-mcp/get-image ## Facts - Tool: `get_image` - Server: NapCat MCP Server (`1021143806/napcat_mcp`) — https://policylayer.com/tools/1021143806-napcat-mcp.md - Homepage: https://github.com/1021143806/napcat_mcp - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "get_image", "arguments": {} } } ``` ## Why get_image is rated Low The tool retrieves or queries image data without altering, deleting, or executing operations. It fits the Read category as it only fetches information. Severity is low because image metadata retrieval poses minimal risk even if misused by an agent. Confidence is high given the clear retrieval semantics in both name and description. From the tool's own definition: "Tool name is 'get_image' and description states 'Get image information' - this is a retrieval operation with no modification or side effects." ## Use case AI agents call get_image to retrieve information from NapCat MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches NapCat MCP Server: ```json { "version": "1", "default": "deny", "tools": { "get_image": {} } } ``` ## Other tools on NapCat MCP Server (56) - `delete_essence_msg` — Destructive — https://policylayer.com/tools/1021143806-napcat-mcp/delete-essence-msg.md - `delete_group_file` — Destructive — https://policylayer.com/tools/1021143806-napcat-mcp/delete-group-file.md - `delete_msg` — Destructive — https://policylayer.com/tools/1021143806-napcat-mcp/delete-msg.md - `set_group_kick` — Destructive — https://policylayer.com/tools/1021143806-napcat-mcp/set-group-kick.md - `set_group_ban` — Execute — https://policylayer.com/tools/1021143806-napcat-mcp/set-group-ban.md - `set_group_whole_ban` — Execute — https://policylayer.com/tools/1021143806-napcat-mcp/set-group-whole-ban.md - `can_send_image` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/can-send-image.md - `can_send_record` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/can-send-record.md - `get_cookies` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-cookies.md - `get_credentials` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-credentials.md - `get_csrf_token` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-csrf-token.md - `get_essence_msg_list` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-essence-msg-list.md - `get_forward_msg` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-forward-msg.md - `get_friend_list` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-friend-list.md - `get_friend_msg_history` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-friend-msg-history.md - `get_group_announcement_list` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-announcement-list.md - `get_group_at_all_remain` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-at-all-remain.md - `get_group_file_system_info` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-file-system-info.md - `get_group_file_url` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-file-url.md - `get_group_files_by_folder` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-files-by-folder.md - `get_group_honor_info` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-honor-info.md - `get_group_ignore_add_request` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-ignore-add-request.md - `get_group_info` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-info.md - `get_group_info_ex` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-info-ex.md - `get_group_list` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-list.md - `get_group_member_info` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-member-info.md - `get_group_member_list` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-member-list.md - `get_group_msg_history` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-msg-history.md - `get_group_root_files` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-root-files.md - `get_group_system_msg` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-system-msg.md - …and 26 more: https://policylayer.com/tools/1021143806-napcat-mcp.md ## For agents This record is a snapshot.
