As the server describes them. The labels are the server's own: it says whether each tool only reads or can change things.
- agent_capabilitiesReturn the tools, scopes, cost table and data coverage available to this session.Read-only
- search_submitSubmit a chart-pattern search. Returns a task id immediately; poll search_status/search_result. Idempotent per request within a session only by the caller's own retry discipline.Can change things
- search_statusReport whether a submitted search is running or complete. A completed search carries its match count and a report_url link to the full human-readable report.Read-only
- search_resultReturn one page of a completed search's per-coin matches plus a report_url link to the full human-readable report. Heavy per-candle series are omitted unless include_series is true.Read-only
- quota_statusReturn the account's remaining tokens so the agent can plan before spending.Read-only
- list_coinsList coins with trading statistics (signal strength, spread, win probability).Read-only
- market_klinesFetch OHLC klines for one symbol and interval.Read-only
- catalog_listList the authenticated user's saved patterns (public fields only).Read-only
- catalog_saveSave a pattern sketch to the user's library. Requires the catalog:write scope, which the user must grant at approval time.Can change things
- analytics_schemaReturn the analytics metric catalogue, dimensions, curated questions, pricing tiers and fast-verification limit. Start here before building a config.Read-only
- analytics_reportReturn one search report, its default analytics spec, ready question configs, suggestions and the estimated cohort. Use report.defaults.spec as the starting config.Read-only
- analytics_quoteValidate a spec and return the runtime token price, cohort estimate, work units and offer_id. Quotes do not spend tokens.Read-only
- analytics_fast_verifyRun the free fast verification over the first 200 matches. It returns a snapshot and never saves an analysis or charges tokens.Read-only
- analytics_config_listList the user's saved Outcome Lab config drafts, optionally for one report.Read-only
- analytics_config_saveSave a named analytics config draft. Pass config_id to update an existing draft; omit it to create a new one. Saving is free and does not create a snapshot.Can change things
- analytics_config_deleteDelete one saved analytics config draft owned by the user.Can change things
- analytics_runRun and save a full Outcome Lab analysis from a quoted spec. This spends tokens; call analytics_quote first and pass its offer_id.Can change things
