Find all documents that reference a given document. Essential before deleting to avoid broken references.
AI agents call sanity_references to retrieve information from Sanity MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query to identify referential relationships. It retrieves information about which documents reference a target document, which is a non-destructive data retrieval operation. While it may inform decisions about deletions, the tool itself does not modify, delete, or execute any side effects.
From the tool's definition Tool description states 'Find all documents that reference a given document' - a query operation that retrieves data without modifying or deleting anything.
Attacks that exploit this kind of access
Find all documents that reference a given document. Essential before deleting to avoid broken references. It is categorised as a Read tool in the Sanity MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Sanity MCP Server MCP server in PolicyLayer and add a rule for sanity_references: 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 Sanity MCP Server. Nothing to install.
sanity_references 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 sanity_references 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 sanity_references. 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.
sanity_references is provided by the Sanity MCP Server MCP server (purple-horizons/sanity-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
