What get_temporal_context does on Fathom Fyi
AI agents call get_temporal_context to retrieve information from Fathom Fyi without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why get_temporal_context is rated Low
This tool queries and returns temporal/historical blockchain data about Bitcoin halving cycles. It provides context and guidance but does not execute trades, move funds, modify positions, run arbitrary code, or delete data. The risk is purely informational—misuse could lead to poor trading decisions, but the tool itself performs only read operations on financial data.
From the tool's definition Tool name contains 'get_' prefix and description states it retrieves historical data (days since halving, cycle phase, historical analogs). No modification, deletion, or execution of external systems occurs. Returns informational financial intelligence only.
Attacks that exploit this kind of access
The rule that runs get_temporal_context safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Fathom Fyi, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_temporal_context, this is the rule to start with:
get_temporal_context is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Fathom Fyi, apply this rule, and every get_temporal_context call is checked against it from then on.
