Get all available plugins including installed and available plugins.
AI agents call get_plugins to retrieve information from HC3 MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that queries and lists available plugins in the HC3 system. No data is created, modified, deleted, or triggered. The blast radius of misuse is minimal since an attacker could only gain information about installed plugins, which is valuable for reconnaissance but does not enable direct harm to the smart home system without additional tools.
From the tool's definition Tool name 'get_plugins' and description 'Get all available plugins including installed and available plugins' indicates a query/retrieval operation with no side effects. Returns information about available plugins without modification.
Attacks that exploit this kind of access
Get all available plugins including installed and available plugins. It is categorised as a Read tool in the HC3 MCP Server MCP Server, which means it retrieves data without modifying state.
Register the HC3 MCP Server MCP server in PolicyLayer and add a rule for get_plugins: 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 HC3 MCP Server. Nothing to install.
get_plugins 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_plugins 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_plugins. 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_plugins is provided by the HC3 MCP Server MCP server (jangabrielsson/hc3_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
get_plugins is one line of HC3 MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
