source_get_content
AI agents call source_get_content to retrieve information from NotebookLM MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to query or retrieve content from sources already added to a notebook. There is no indication of modification, deletion, code execution, or financial impact. The 'get' verb and '_content' suffix strongly suggest a read-only retrieval operation. Confidence is reduced from 0.85 to 0.75 due to missing tool description, which limits certainty about edge cases or hidden side effects.
From the tool's definition Tool name 'source_get_content' indicates retrieval of content from a source. The verb 'get' is characteristic of read operations.

source_get_content. It is categorised as a Read tool in the NotebookLM MCP Server MCP Server, which means it retrieves data without modifying state.
Register the NotebookLM MCP Server MCP server in PolicyLayer and add a rule for source_get_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 NotebookLM MCP Server. Nothing to install.
source_get_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 source_get_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 source_get_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.
source_get_content is provided by the NotebookLM MCP Server MCP server (set2374/notebooklm-mcp-archived). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
