compute_distance
AI agents call compute_distance to retrieve information from XHelio-SPICE 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 a calculation based on ephemeris data and return a result, with no indication of side effects, data modification, or external operations. It fits the Read category as a data retrieval/computation tool. Confidence is slightly reduced due to the empty description, but the context and naming convention strongly suggest a read-only operation.
From the tool's definition Tool name 'compute_distance' suggests a computational query that returns distance values without modifying data.
Attacks that exploit this kind of access
compute_distance. It is categorised as a Read tool in the XHelio-SPICE MCP Server, which means it retrieves data without modifying state.
Register the XHelio-SPICE MCP server in PolicyLayer and add a rule for compute_distance: 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 XHelio-SPICE. Nothing to install.
compute_distance 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 compute_distance 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 compute_distance. 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.
compute_distance is provided by the XHelio-SPICE MCP server (xhelio-spice). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
