AI agents call find_by_attribute to retrieve information from MCP Modus without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries component documentation based on attribute filters. It has no capacity to modify, delete, execute code, or affect financial systems. The operation is purely informational and read-only, consistent with a documentation lookup service.
From the tool's definition Tool name 'find_by_attribute' and description 'Find components that have a specific attribute or property' indicate a search/query operation with no side effects.
Attacks that exploit this kind of access
Find components that have a specific attribute or property. It is categorised as a Read tool in the MCP Modus MCP Server, which means it retrieves data without modifying state.
Register the MCP Modus MCP server in PolicyLayer and add a rule for find_by_attribute: 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 Modus. Nothing to install.
find_by_attribute 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 find_by_attribute 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 find_by_attribute. 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.
find_by_attribute is provided by the MCP Modus MCP server (julianoczkowski/mcp-modus). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
