AI agents call estimate_capacity to retrieve information from Orihime without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to perform capacity estimation—likely analyzing code metrics or performance characteristics from the indexed knowledge graph. No evidence suggests it modifies data, executes arbitrary code, deletes resources, or involves financial operations. Despite the empty description lowering confidence, the tool name and server purpose (knowledge graph analysis) strongly indicate this is a Read operation.
From the tool's definition Tool name 'estimate_capacity' suggests a query or analysis operation. The description is empty, making definitive classification difficult. However, the naming convention aligns with other sibling tools (find_*, estimate_*) that are analysis/query-based.
Attacks that exploit this kind of access
estimate_capacity. It is categorised as a Read tool in the Orihime MCP Server, which means it retrieves data without modifying state.
Register the Orihime MCP server in PolicyLayer and add a rule for estimate_capacity: 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 Orihime. Nothing to install.
estimate_capacity 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 estimate_capacity 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 estimate_capacity. 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.
estimate_capacity is provided by the Orihime MCP server (srinivasan-sundaresan95/orihime). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
