What set_feature_flag does on Mapi Agent Memory
AI agents use set_feature_flag to create or update resources in Mapi Agent Memory, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mapi Agent Memory environment.
Why set_feature_flag is rated Medium
Feature flag operations modify system configuration that affects agent behavior. This is reversible (flags can be toggled), so it falls under Write rather than Destructive. High severity due to potential to enable/disable critical agent capabilities or governance features. Confidence reduced from higher due to empty description, but the function name and server context provide sufficient basis for classification.
From the tool's definition Tool name 'set_feature_flag' indicates modification of feature flag state. While description is empty, the name and server context (auditable memory and governance for AI agents) suggest this creates or modifies configuration that controls agent behavior.
Attacks that exploit this kind of access
The rule that runs set_feature_flag safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mapi Agent Memory, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For set_feature_flag, this is the rule to start with:
set_feature_flag stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Mapi Agent Memory, apply this rule, and every set_feature_flag call is checked against it from then on.
Questions about set_feature_flag
set_feature_flag is a write tool on the Mapi Agent Memory MCP server. It is categorised as a Write tool in the Mapi Agent Memory MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mapi Agent Memory MCP server in PolicyLayer and add a rule for set_feature_flag: 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 Mapi Agent Memory. Nothing to install.
set_feature_flag is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the set_feature_flag 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 set_feature_flag. 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.
set_feature_flag is provided by the Mapi Agent Memory MCP server (cabo0m/mapi-agent-memory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
