Get complete content of a specified URL webpage, including HTML structure and page data
AI agents call get_page_content to retrieve information from Dev Tool MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries webpage content without side effects. It extracts existing data (HTML structure and page data) from a URL without creating, modifying, deleting, or executing operations. It falls squarely within the Read category.
From the tool's definition Tool name 'get_page_content' and description 'Get complete content of a specified URL webpage' indicate data retrieval with no modification or execution capability. The server description mentions 'page content extraction' as a retrieval function.

Get complete content of a specified URL webpage, including HTML structure and page data. It is categorised as a Read tool in the Dev Tool MCP MCP Server, which means it retrieves data without modifying state.
Register the Dev Tool MCP server in PolicyLayer and add a rule for get_page_content: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Dev Tool MCP. Nothing to install.
get_page_content is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_page_content rule in your PolicyLayer 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 PolicyLayer policy for get_page_content. 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.
get_page_content is provided by the Dev Tool MCP server (osins/dev-tool-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
get_page_content is one line of Dev Tool's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
