get_reality_scoreEstimate the modeled annual value of a supported premium credit card for a consumer segment.No findings
Why it is in this group
- The name "get_reality_score" says "get": a word for reading.
Description, as the server wrote it
Estimate the modeled annual value of a supported premium credit card for a consumer segment. Supply a card slug or name and optionally a segment ID; the default is occasional-traveler. Return segment assumptions, score, rewards, credits, perks, fee, interest, friction, net value, caveats, sources, verification date, freshness and methodology. Gross recovered value is rewards + credits + perks. breakageMultiplier is gross recovered value / advertised value, NOT divided by annual fee. feeRecoveryMultiplier is max(0, gross recovered value - interest drag - rewards friction discount) / annual fee, before subtracting the fee. Friction applies to raw rewards only. Reality Score is 100 * net realized value / advertised value. Ratios are rounded. These are scenario estimates, not personalized advice or guaranteed benefits. Preserve stale or unavailable labels; do not infer that all terms share the observation date. Unknown cards or segments return a structured error with suggestions.

get_top_hysa_ratesReturn top high-yield savings rates with freshness and attribution.No findings

- The name "get_top_hysa_rates" says "get": a word for reading.
Description, as the server wrote it
Return top high-yield savings rates with freshness and attribution. Answers only from the editor-approved snapshot; before its first release it returns no ranked rates and says so (approval_status: not_yet_approved). approvedOnly makes the requirement explicit. detail=full adds every listed account marked verified or tracked, best picks, movers, history and a headline summary.

get_top_ratesReturn top SwitchWize rates with freshness and attribution.No findings
Why it is in this group
- The name "get_top_rates" says "get": a word for reading.
Description, as the server wrote it
Return top SwitchWize rates with freshness and attribution. Savings, CDs, checking and money market answer only from their editor-approved snapshot. A category with no approved release yet returns no ranked rates and says so (approval_status: not_yet_approved) rather than serving unverified observations; approvedOnly makes that requirement explicit. Approved responses include product terms and field evidence; stale or unavailable releases return no ranked rates. detail=full (savings) adds the complete shared build: every listed account marked verified or tracked, best picks, movers, history and a headline summary.

1 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
