Single-target operation
Part of the Hwpx MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use insert_image_in_cell to create or modify resources in Hwpx. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call insert_image_in_cell repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Hwpx.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

š Insert an image INSIDE a specific table cell (HWPX only). The image appears inline within the cell content. ā ļø IMPORTANT: Use this tool (NOT insert_image) when inserting images into table cells! When to use: 1. find_insert_position_after_header returned found_in='table_cell' ā use table_info (table_index, row, col) 2. You want to add an image to a specific cell you already know How to get table_index: - From find_insert_position_after_header result: table_info.table_index - Or use get_table_map to list all tables and find the index Positioning within cell: - By default, image is inserted at the beginning of the cell - Use after_text to insert the image after a specific paragraph containing that text. It is categorised as a Write tool in the Hwpx MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Add a rule in your Intercept YAML policy under the tools section for insert_image_in_cell. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Hwpx MCP server.
insert_image_in_cell is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the insert_image_in_cell rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the Intercept policy for insert_image_in_cell. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
insert_image_in_cell is provided by the Hwpx MCP server (hwpx-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
