Retrieve complete details for a specific glucose reading by ID.
AI agents call fetch to retrieve information from MCP Glucose Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves glucose readings from a health storage API by ID lookup. It performs a query operation that returns data without modifying, deleting, or executing any actions. The operation is read-only and has no destructive or financial implications.
From the tool's definition Tool name 'fetch' and description 'Retrieve complete details for a specific glucose reading by ID' indicate data retrieval with no side effects.
Attacks that exploit this kind of access
Retrieve complete details for a specific glucose reading by ID. It is categorised as a Read tool in the MCP Glucose Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Glucose Server MCP server in PolicyLayer and add a rule for fetch: 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 MCP Glucose Server. Nothing to install.
fetch 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 fetch 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 fetch. 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.
fetch is provided by the MCP Glucose Server MCP server (lucas-1000/mcp-glucose). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
