Search Nuclino content within a specific workspace. Use this when you know which workspace to search in - first get workspaces with get_workspaces.
AI agents call search_by_workspace to retrieve information from Nuclino MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a search/retrieval tool that queries content within a workspace boundary. It has no side effects—it does not create, modify, delete, or execute operations. The low severity reflects minimal blast radius: misuse would only expose data the agent is already authorized to access within the workspace. Confidence is high because the description clearly indicates read-only retrieval behavior.
From the tool's definition Tool description states it 'Search[es] Nuclino content within a specific workspace' with no mention of modification, deletion, or execution. The verb 'search' and absence of write/delete/execute language indicate retrieval-only functionality.
Attacks that exploit this kind of access
Search Nuclino content within a specific workspace. Use this when you know which workspace to search in - first get workspaces with get_workspaces. It is categorised as a Read tool in the Nuclino MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Nuclino MCP Server MCP server in PolicyLayer and add a rule for search_by_workspace: 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 Nuclino MCP Server. Nothing to install.
search_by_workspace 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_by_workspace 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 search_by_workspace. 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.
search_by_workspace is provided by the Nuclino MCP Server MCP server (urbantz-logistics/mcp-nuclino). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
