AI agents call get_full_context to retrieve information from Yt without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to retrieve or aggregate context information about video content, consistent with the server's purpose of analyzing YouTube videos. No modification, execution, deletion, or financial impact is implied. While confidence is moderate due to empty description, the context of sibling read-only tools and the retrieval-oriented naming strongly suggests this is a Read operation with low blast radius.
From the tool's definition Tool name 'get_full_context' suggests retrieval/analysis of video data. Description is empty, but sibling tools (ask_about_video, extract_frames, get_video_transcript, summarize_video) are all read-only analysis operations on YouTube content.
Attacks that exploit this kind of access
get_full_context. It is categorised as a Read tool in the Yt MCP Server, which means it retrieves data without modifying state.
Register the Yt MCP server in PolicyLayer and add a rule for get_full_context: 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 Yt. Nothing to install.
get_full_context 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_full_context 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_full_context. 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_full_context is provided by the Yt MCP server (pakmangames/yt-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
