get_stablecoin_flows
Track stablecoin supply changes across USDT, USDC, and all major stablecoins. Shows total supply, 24h/7d/30d minting and redemptions, net capital flow signal, depeg warnings, and liquidity assessment. Stablecoin flows are a leading indicator of capital entering or leaving crypto.

What get_stablecoin_flows does on Fathom Fyi
AI agents call get_stablecoin_flows 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_stablecoin_flows is rated Low
This tool retrieves and aggregates financial data (stablecoin metrics and flows) for analysis purposes. It performs no mutations, executions, or irreversible actions. While it provides intelligence for financial decision-making, the tool itself only reads and displays data without executing trades, moving funds, or modifying any state.
From the tool's definition Tool description explicitly describes tracking and showing data: 'Track stablecoin supply changes', 'Shows total supply', 'net capital flow signal', 'depeg warnings', and 'liquidity assessment'.
Attacks that exploit this kind of access
The rule that runs get_stablecoin_flows 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_stablecoin_flows, this is the rule to start with:
get_stablecoin_flows 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_stablecoin_flows call is checked against it from then on.

Register the Fathom Fyi MCP server in PolicyLayer and add a rule for get_stablecoin_flows: 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_stablecoin_flows 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_stablecoin_flows 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_stablecoin_flows. 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_stablecoin_flows 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.
