Fetch a page and extract content in any format — text, markdown, html, links, or cookies. Optionally evaluate JavaScript. One-shot: no session needed.
AI agents call browse_page to retrieve information from Obscura MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
browse_page is a read-only data retrieval tool. It fetches web pages and extracts information (text, markdown, HTML, links, cookies) without modifying data, executing arbitrary code, or triggering destructive operations. Even with optional JavaScript evaluation, the capability is scoped to content extraction on a single page in a one-shot manner, minimizing blast radius. This is a classic Read operation.
From the tool's definition Tool description states "Fetch a page and extract content in any format — text, markdown, html, links, or cookies." The verb "fetch" and "extract" indicate retrieval operations.
Attacks that exploit this kind of access
Fetch a page and extract content in any format — text, markdown, html, links, or cookies. Optionally evaluate JavaScript. One-shot: no session needed. It is categorised as a Read tool in the Obscura MCP MCP Server, which means it retrieves data without modifying state.
Register the Obscura MCP server in PolicyLayer and add a rule for browse_page: 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 Obscura MCP. Nothing to install.
browse_page 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 browse_page 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 browse_page. 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.
browse_page is provided by the Obscura MCP server (obscura-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
