Get the archive URL for a specific snapshot of a page.
AI agents call get_snapshot to retrieve information from Arquivo Pt without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a straightforward query operation that returns a reference URL to archived content. There are no side effects, data modifications, code execution, destructive operations, or financial implications. It simply retrieves and returns information about an archived snapshot, consistent with the Read category for tools that query or retrieve data without side effects.
From the tool's definition The tool 'get_snapshot' retrieves an archive URL for a specific snapshot of a page from Arquivo.pt. The description explicitly indicates retrieval of a URL reference with no modification or execution capability.
Attacks that exploit this kind of access
Get the archive URL for a specific snapshot of a page. It is categorised as a Read tool in the Arquivo Pt MCP Server, which means it retrieves data without modifying state.
Register the Arquivo Pt MCP server in PolicyLayer and add a rule for get_snapshot: 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 Arquivo Pt. Nothing to install.
get_snapshot 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_snapshot 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_snapshot. 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_snapshot is provided by the Arquivo Pt MCP server (thaenor/arquivo-pt-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
