MCP tools · 15 exposed · ~2,136 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
compute ~404

The core tool. Validates a ComputeRequest (kind plus the per-kind fields) and runs the engine, returning the full ComputeResult: a horary judgment, transit aspects + annual profection, a natal/electional chart, optional relocation, and (when `journal` is supplied) the auto-logged entry id.

NameTypeReqDescription
journalobject–Optional auto-logging: when present, the compute appends a journal entry (the engine-derived fields plus this question) and returns the new entry id.
kindstringyesChart kind. Drives which other fields are required.
locationobject–Required for "electional": the place to cast each candidate chart for.
momentobject–The chart's own moment. Required for natal/transit/horary; for "transit" use now.
natalobject–Required only for kind "transit": the natal chart.
querentHouseinteger–Horary only. Radix house (1..12) the QUERENT's significator is read from (default 1, the asker). Set to TURN THE CHART for a third-party question: the querent house becomes the radix house of the per…
quesitedHouseinteger–House of the matter (2..12). Required for horary; reused by electional.
relocationobject–Optional: recast the chart's houses/angles for another place (same moment).
significatorHintsobject–Optional for "electional": steer significator choice/weighting.
stepMinutesnumber–Required for "electional": scan interval in minutes (e.g. 15).
windowobject–Required for "electional": local-time window to scan (ISO without offset).

No output schema declared.

No examples provided.

electional ~126

Convenience wrapper over compute for an electional search: scans a local-time window at a step interval for the best moments to act on a matter (quesitedHouse), returning the top candidates and the #1 chart.

NameTypeReqDescription
locationobjectyesThe place to cast each candidate chart for.
quesitedHouseintegeryesHouse of the matter (2..12).
significatorHintsobject––
stepMinutesnumberyesScan interval in minutes (e.g. 15).
windowobjectyesLocal-time window to scan (ISO without offset).

No output schema declared.

No examples provided.

geocode ~96

Look up a city name in the cached offline GeoNames gazetteer, returning authoritative lat/lon + IANA timezone (most populous first). Errors with an install hint if the gazetteer is absent (use the geocode_install tool, with user consent).

NameTypeReqDescription
limitinteger–Max matches to return (default 5).
querystringyesCity name, e.g. "Tokyo" or "San Francisco".

No output schema declared.

No examples provided.

geocode_install ~182

One-time setup for the geocode tool: downloads the GeoNames cities15000 gazetteer (a single ~3 MB network fetch from geonames.org, ~8 MB on disk once extracted) into local storage under KAIROS_HOME. This is the only network download Kairos ever performs and it must stay strictly user-initiated: ASK THE USER FOR EXPLICIT CONSENT before calling ("download the offline city database — ~3 MB, one time?") and only call on a clear yes. Idempotent and safe to call when unsure — if the gazetteer is already installed it performs no network access and returns { installed: true, alreadyInstalled: true, path, cities }; a fresh download returns the same shape with alreadyInstalled: false.

NameTypeReqDescription
forceboolean–Re-download even when already installed (still requires user consent).

No output schema declared.

No examples provided.

horary ~132

Convenience wrapper over compute for a horary question: builds the request from a moment + quesitedHouse and returns the judgment (lean, confidence, perfection picture, timing).

NameTypeReqDescription
journalobject––
momentobjectyesThe moment the question was asked (with place).
querentHouseinteger–Radix house (1..12) the querent's significator is read from (default 1). Set to turn the chart for a third-party question.
quesitedHouseintegeryesHouse of the matter asked about (2..12).
relocationobject––

No output schema declared.

No examples provided.

memory_calibration ~46

Report Kairos's hit-rate by confidence band over resolved, directional readings — a personal pattern, not proof.

NameTypeReqDescription
profilestring–Profile slug (default: the active one).

No output schema declared.

No examples provided.

memory_calibration_card ~130

Render Kairos's calibration as a clean, HONEST, shareable card — Markdown (default) or a self-contained SVG badge. Always surfaces the sample size (n resolved) and the small-sample caveat so a tiny streak is never presented as proof; when nothing has resolved yet it renders an explicit 'no outcomes yet' state instead of a misleading 100%/0%. Returns the rendered card as plain text.

NameTypeReqDescription
formatstring–Card format: "markdown" (default) or "svg".
profilestring–Profile slug (default: the active one).

No output schema declared.

No examples provided.

memory_due ~52

List logged-but-unresolved readings that are now ripe to ask about (most-ripe first), so Kairos can follow up on past questions.

NameTypeReqDescription
profilestring–Profile slug (default: the active one).

No output schema declared.

No examples provided.

memory_log ~187

Append a reading to the local append-only journal and return its id. Note: passing `journal` to the compute tool is the PREFERRED path — it captures the engine-derived lean/confidence/score itself so the track record can't drift. Use this only to log a reading computed elsewhere.

NameTypeReqDescription
confidencestring––
expectedResolutionAtstring–When this reading is expected resolvable (the "ask me later" date, ISO-8601).
kindstringyesThe chart kind this reading used.
leanstring––
profilestring–Profile slug to log against (default: the active one).
quesitedHouseinteger––
questionstringyesThe user's question, recorded verbatim.
scorenumber––
verdictTextstring–The plain-language verdict given at log time.

No output schema declared.

No examples provided.

memory_outcome ~81

Record the outcome of a previously logged reading by id (happened / did-not-happen / partial / unknown), feeding the calibration track record.

NameTypeReqDescription
idstringyesThe journal entry id returned by memory_log or compute.
notestring–Optional note on what actually happened.
outcomestringyesHow the matter actually resolved.

No output schema declared.

No examples provided.

natal ~58

Convenience wrapper over compute for a natal chart: casts the chart for a single birth moment + place (planets, houses, aspects, dignities, lots).

NameTypeReqDescription
momentobjectyesThe birth moment + place.
relocationobject––

No output schema declared.

No examples provided.

profile_get ~49

Return the stored profile (birth + home places) for the active profile, or a named one. Null when nothing is saved.

NameTypeReqDescription
profilestring–Profile slug (default: the active one).

No output schema declared.

No examples provided.

profile_set ~73

Deep-merge a patch over the profile (birth/home merged field-wise) and return the merged profile. Stored LOCALLY only under KAIROS_HOME — birth data never leaves the machine.

NameTypeReqDescription
patchobjectyesPartial profile to merge in.
profilestring–Profile slug (default: the active one).

No output schema declared.

No examples provided.

render_wheel ~442

Takes the SAME request as compute (a ComputeRequest), runs the engine, and writes ONE self-contained chart wheel as an openable .html file (web assets + the ComputeResult inlined, no network needed). Returns { path, note } with the artifact's absolute path for the user to open in a browser. The visual verdict panel covers horary/electional; transit/natal render the wheel without one. Errors when the request produces no chart (e.g. an electional with no candidates).

NameTypeReqDescription
journalobject–Optional auto-logging: when present, the compute appends a journal entry (the engine-derived fields plus this question) and returns the new entry id.
kindstringyesChart kind. Drives which other fields are required.
locationobject–Required for "electional": the place to cast each candidate chart for.
momentobject–The chart's own moment. Required for natal/transit/horary; for "transit" use now.
natalobject–Required only for kind "transit": the natal chart.
querentHouseinteger–Horary only. Radix house (1..12) the QUERENT's significator is read from (default 1, the asker). Set to TURN THE CHART for a third-party question: the querent house becomes the radix house of the per…
quesitedHouseinteger–House of the matter (2..12). Required for horary; reused by electional.
relocationobject–Optional: recast the chart's houses/angles for another place (same moment).
significatorHintsobject–Optional for "electional": steer significator choice/weighting.
stepMinutesnumber–Required for "electional": scan interval in minutes (e.g. 15).
windowobject–Required for "electional": local-time window to scan (ISO without offset).

No output schema declared.

No examples provided.

transit ~78

Convenience wrapper over compute for a transit reading: compares a transit `moment` against a `natal` chart and returns transit aspects plus the annual profection (lord of the year).

NameTypeReqDescription
momentobjectyesThe transit moment (typically "now").
natalobjectyesThe natal chart to compare against.
relocationobject––

No output schema declared.

No examples provided.
