AI agents call getFoodLogs to retrieve information from FitBit MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'get' prefix combined with the established pattern of sibling read-only tools accessing Fitbit data indicates this retrieves food log records without side effects. No modification, deletion, or external operation triggering is implied. The minimal blast radius of unauthorized food log access to a personal health database justifies a low severity rating.
From the tool's definition Tool name 'getFoodLogs' indicates data retrieval. Sibling tools on the server (getActiveZoneMinutes, getActivities, getBadges, getBodyMeasurements, getCalories, getDevices, getDistance, getFloorsClimbed, getHeartRate, getLifetimeStats) are all read-only…
Documented attack patterns abuse exactly the kind of access getFoodLogs gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and FitBit MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for getFoodLogs:
{
"version": "1",
"default": "deny",
"tools": {
"getFoodLogs": {}
}
}getFoodLogs is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

getFoodLogs. It is categorised as a Read tool in the FitBit MCP MCP Server, which means it retrieves data without modifying state.
Register the FitBit MCP server in PolicyLayer and add a rule for getFoodLogs: 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 FitBit MCP. Nothing to install.
getFoodLogs 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 getFoodLogs 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 getFoodLogs. 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.
getFoodLogs is provided by the FitBit MCP server (nitayrabi/fitbit-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from FitBit MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
