Retrieves an item from a Azure Cosmos DB container by its ID
AI agents call get_item to retrieve information from Azure Cosmos DB 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 operation that queries and returns data from a database without any side effects. It retrieves a single item by ID from an Azure Cosmos DB container, which is a straightforward data retrieval operation. The lack of mutation capabilities places it firmly in the Read category with low severity risk.
From the tool's definition Tool description states 'Retrieves an item from a Azure Cosmos DB container by its ID' - retrieval with no modification.
Attacks that exploit this kind of access
Retrieves an item from a Azure Cosmos DB container by its ID. It is categorised as a Read tool in the Azure Cosmos DB MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Azure Cosmos DB MCP Server MCP server in PolicyLayer and add a rule for get_item: 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 Azure Cosmos DB MCP Server. Nothing to install.
get_item 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_item 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_item. 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_item is provided by the Azure Cosmos DB MCP Server MCP server (robinong79/mcp-cosmos). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
