List all available computing backends and their capabilities
AI agents call list_backends to retrieve information from Scicompute without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays information about available backends without modifying state, executing code, or performing any irreversible actions. It is a straightforward informational read operation with minimal security risk.
From the tool's definition Tool name 'list_backends' and description 'List all available computing backends and their capabilities' indicate a query/retrieval operation with no side effects.
Attacks that exploit this kind of access
List all available computing backends and their capabilities. It is categorised as a Read tool in the Scicompute MCP Server, which means it retrieves data without modifying state.
Register the Scicompute MCP server in PolicyLayer and add a rule for list_backends: 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 Scicompute. Nothing to install.
list_backends 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 list_backends 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 list_backends. 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.
list_backends is provided by the Scicompute MCP server (sanshanjianke/scicompute-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
