Get all tags in a workspace, or tags for a specific page if pageId is provided. Workspace tags return the full tag vocabulary; page tags return only tags applied to that page. Use update_page_tags to modify a page
AI agents call get_tags to retrieve information from Fusebase 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 tag metadata without side effects. It performs a read-only query operation that returns existing data (workspace tags or page-specific tags) without creating, modifying, or deleting anything. The low severity reflects minimal risk from misuse — an agent could retrieve all tags, but this causes no damage, cost, or operational disruption.
From the tool's definition Tool name is 'get_tags' and description states it 'Get[s] all tags in a workspace, or tags for a specific page if pageId is provided' — purely a retrieval operation with no modification capability.
Attacks that exploit this kind of access
Get all tags in a workspace, or tags for a specific page if pageId is provided. Workspace tags return the full tag vocabulary; page tags return only tags applied to that page. Use update_page_tags to modify a page. It is categorised as a Read tool in the Fusebase MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Fusebase MCP Server MCP server in PolicyLayer and add a rule for get_tags: 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 Fusebase MCP Server. Nothing to install.
get_tags 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_tags 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_tags. 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_tags is provided by the Fusebase MCP Server MCP server (ryan-haver/fusebase-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
