Get a specific chunk (page/section) of a document. Useful for large documents to retrieve content in parts.
AI agents call get_document_chunk to retrieve information from Gemini Search MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward data retrieval tool that fetches pre-defined sections of documents. It has no capability to modify, delete, or execute operations. The worst-case misuse would be accessing unintended document content, which poses minimal risk compared to other categories. Low severity reflects the read-only nature and lack of destructive or system-level impact.
From the tool's definition Tool retrieves 'a specific chunk (page/section) of a document' - a read-only operation with no side effects. The description explicitly indicates retrieval of existing content in parts.
Attacks that exploit this kind of access
Get a specific chunk (page/section) of a document. Useful for large documents to retrieve content in parts. It is categorised as a Read tool in the Gemini Search MCP MCP Server, which means it retrieves data without modifying state.
Register the Gemini Search MCP server in PolicyLayer and add a rule for get_document_chunk: 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 Gemini Search MCP. Nothing to install.
get_document_chunk 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_document_chunk 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_document_chunk. 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_document_chunk is provided by the Gemini Search MCP server (mimiclab/geminisearchmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
