Changes things 1Creates or changes something that can be changed back.Claude Code: ask

what_to_watchHow many points each instrument is from the next zone boundary up or down, which sensors are closest to switching on or off (threshold 80), and the freshest and stalest inputs.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
How many points each instrument is from the next zone boundary up or down, which sensors are closest to switching on or off (threshold 80), and the freshest and stalest inputs. Use for "what would change the picture?".

Why it is in this group
- The name "find_similar_days" says "find": a word for reading.
Description, as the server wrote it
Days since 1990 when the 14 sensors of the crisis meter, market-top risk and recession risk stood closest to a given day (default: today), at least half a year apart and at least a year before the given day, and what followed within 12 months: the crisis meter peak, a US recession (NBER), an S&P 500 bear market, the dollar index. History, not a forecast — always show the spread of outcomes.

get_changes_sinceWhat moved between two dates and why: each instrument (from → to, zone change), the sensors that moved most and any that switched on or off, and the filters.No findings
Why it is in this group
- The name "get_changes_since" says "get": a word for reading.
Description, as the server wrote it
What moved between two dates and why: each instrument (from → to, zone change), the sensors that moved most and any that switched on or off, and the filters. Use when the user asked before ("since last week / since I last checked") or asks why a reading changed.
Annotations the server declares

Why it is in this group
- The name "get_current_readings" says "get": a word for reading.
Description, as the server wrote it
Today's readings with the data date: Dollar System Index (where the dollar system stands and what it is made of), Crisis meter (stress already present in credit and funding, four sensors with week-ago and month-ago values), market-top risk and US recession risk (how often an S&P 500 bear market or a US recession followed the same zone since 1990, with the number of independent episodes behind each number), what changed this week, and a link to the public daily record. Say the data date and credit "Isoba (LOKIO)". Describe readings as where things stand now and as history ("in similar periods since 1990, X happened in N of M cases"), never as a forecast, a signal, or advice to buy or sell. If someone asks what to do with their own money, give the readings and say that this is not investment advice.

Why it is in this group
- The name "get_expectations" says "get": a word for reading.
Description, as the server wrote it
What markets price now (Fed rate path from the 2-year Treasury yield, 5-year breakeven inflation, yields) and what happened over the next 12 months after the 10 days since 1990 most similar to today (same 14 sensors as find_similar_days, at least half a year apart), with the number of distinct cycles behind them: US dollar, US stocks (market value of companies, Fed Z.1), 10-year Treasury return, Fed rate, core inflation, unemployment, WTI oil, yield curve, corporate bond spread, cash vs inflation, M2 money growth, and the crypto backdrop (dollar and M2 — there is no open crypto price history since 1990). Report counts ("rose in 9 of 10"), the median and the range, and how many cycles stand behind them. History and market prices, not a forecast. Say the data date and credit "Isoba (LOKIO)". Describe readings as where things stand now and as history ("in similar periods since 1990, X happened in N of M cases"), never as a forecast, a signal, or advice to buy or sell. If someone asks what to do with their own money, give the readings and say that this is not investment advice.

get_monthly_historyMonthly averages of one or several instruments between two months (DSI since 2006, the others since 1990), with the zone of each month.No findings
Why it is in this group
- The name "get_monthly_history" says "get": a word for reading.
Description, as the server wrote it
Monthly averages of one or several instruments between two months (DSI since 2006, the others since 1990), with the zone of each month. Use for trends and to see what the instruments showed around past events.

Why it is in this group
- The name "get_readings_on_date" says "get": a word for reading.
Description, as the server wrote it
What Isoba showed on any working day since 1990-01-01: the four instruments with zones, every sensor, the eight filters (since 2006), the yield curve and the four credit inputs — computed point-in-time from data published by that day. Use for "what did it show before 2008 / on the day of COVID?".
Annotations the server declares
- title: Isoba: readings on a date
- readOnlyHint: true
- idempotentHint: true
- openWorldHint: false
get_track_recordHow Isoba behaved when run point-in-time over every working day since 1990 (only data published by each day, checked for look-ahead).No findings
Why it is in this group
- The name "get_track_record" says "get": a word for reading.
Description, as the server wrote it
How Isoba behaved when run point-in-time over every working day since 1990 (only data published by each day, checked for look-ahead). Default section "summary" is short; ask for a section (crisis_events, recessions, market_tops, false_alarms, by_year, methods, all) or one event (gulf, ltcm, dotcom, sept11, worldcom, bnp, lehman, euro, downgrade, china, oil2016, q4_2018, covid, bear2022, svb, tariffs — or its year). Call it before claiming reliability.
Annotations the server declares
- title: Isoba: tested on history
- readOnlyHint: true
- idempotentHint: true
- openWorldHint: false

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

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.
