Search cell sources in a local notebook.
AI agents call search_local_cells to retrieve information from Pypi:colab Drive without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries notebook cell content without creating, modifying, deleting, or executing any code. It performs a passive search operation that returns information only, matching the 'Read' category definition of tools that retrieve or query data with no side effects.
From the tool's definition Tool name 'search_local_cells' and description 'Search cell sources in a local notebook' indicate data retrieval with no modification or side effects. Searching is a read-only query operation.

Register the Pypi:colab Drive MCP server in PolicyLayer and add a rule for search_local_cells: 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 Pypi:colab Drive. Nothing to install.
search_local_cells 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 search_local_cells 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.
