Get all workspaces available to the current user. Use this to get workspace IDs for search_by_workspace.
AI agents call get_workspaces 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 tool retrieves metadata about workspaces without creating, modifying, or deleting any data. It is purely informational and returns data scoped to the authenticated user's permissions. The low severity reflects that workspace metadata is generally not sensitive and the operation has no side effects.
From the tool's definition Tool description states 'Get all workspaces available to the current user' - a retrieval operation with no modification capability. Grouped with other sibling Read tools (get_item, get_teams, get_user, get_users) that fetch data structures.
Attacks that exploit this kind of access
Get all workspaces available to the current user. Use this to get workspace IDs for search_by_workspace. 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 get_workspaces: 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.
get_workspaces 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_workspaces 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_workspaces. 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_workspaces 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.
