AI agents call get_asset_momentum to retrieve information from Fathom Fyi without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a pure data retrieval tool that analyzes and returns momentum metrics for financial assets. While it provides decision-support information for a financial context (trading timing), it does not execute trades, move money, or commit financial obligations.
From the tool's definition Tool returns momentum signal data including direction, strength, confidence_score, RSI, ATR percentile, Bollinger bandwidth, volatility state, volume trend, and momentum score.
Attacks that exploit this kind of access
Short-term momentum signal for any asset. Returns direction, strength, confidence_score (-100 to +100), RSI, ATR percentile, Bollinger bandwidth, volatility state (compressed/normal/expanding/extreme), volume trend, and momentum score. Timeframes: 15m, 1h, 4h, 1d, 7d. Essential for timing entries and exits. It is categorised as a Read tool in the Fathom Fyi MCP Server, which means it retrieves data without modifying state.
Register the Fathom Fyi MCP server in PolicyLayer and add a rule for get_asset_momentum: 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 Fathom Fyi. Nothing to install.
get_asset_momentum 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 get_asset_momentum 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 get_asset_momentum. 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.
get_asset_momentum is provided by the Fathom Fyi MCP server (0xhashy/fathom-fyi). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
get_asset_momentum is one line of Fathom Fyi's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
