A Candid `method` query may be anonymous or as your account and returns textual Candid; an `oql` query **requires** `derivation_origin` and returns `columns` + `rows` (a table) with `has_more`, validating `start` against the schema on an empty result. On an OQL canister a Candid `method` query is rejected — use `oql`. `candid` is a fallback: the `.did` interface text to encode/decode against when the canister exposes no `candid:service` metadata.

The refusal directs the user to perform the operation outside the connector, in a trusted interface they control — or, for canister creation and funding, with the [icp CLI](https://github.com/dfinity/icp-cli) in their own terminal. The policy is stated in the server-level instructions, deliberately not in any tool description. `candid` is the same `.did` fallback as on `canister_query`, used when the interface isn't published on-chain.

Lookalike domains are unrelated or squatted sites, and open_app / \ - every URL-taking tool REFUSES an origin that shows no evidence of being an Internet \ - Computer app instead of resolving it to a wrong identity. (For a token/service \ - name or a canister id you don't have, web search or ask the user.)\n\n\ - \"MY / OUR …\" IS AN AUTHENTICATED READ. A question about the USER's OWN data in an app \ - (\"who am I meeting with…\", \"my bookings\", \"our open orders\") reads data the app gates \ - by the CALLER's principal. An OQL read (get_canister_oql_schema, and canister_query \ - with the `oql` argument) REQUIRES the app's \ - `derivation_origin` (from open_app / resolve_app) — anonymous per-app reads are \ - disabled for now, so a call with no origin is REJECTED with guidance to pass it, rather \ - than silently returning empty. Authenticating never hurts a public read either — the \ - canister serves the request regardless of principal — so always pass the origin for app \ - data. (canister_query can still run a Candid `method` query anonymously for genuinely \ - public canisters like ledgers.)\n\n\ - INSPECTING A CANISTER. `get_canister_candid` fetches the interface and reports two \ - capability flags: `oql` and `api_doc_available` (open_app reports the same per \ - canister). If `oql: true`, READ the canister via OQL, in order: `icp_oql_guide` (the \ - JSON dialect, once) → `get_canister_oql_schema` (the entities and fields) → \ - `canister_query` with the `oql` argument \ - (run a JSON query, get a table). These wrap the canister's `schema`/`execute` methods, \ - so you never hand-encode Candid for OQL — and on an OQL canister a Candid `method` query \ - through canister_query is REJECTED (use `oql`; canister_update_call handles UPDATES). \ - Call `get_canister_api_doc` ONLY when `api_doc_available` is true: then it returns a \ - prose \"how this app behaves\" guide (units, auth, lifecycle, mutation safety, polling, \ - gotchas) the Candid types don't convey; when the flag is false the canister has no such \ - doc and the Candid types ARE the interface — don't call it.\n\n\ - PRESENT VALUES IN THE USER'S LOCAL FORMAT. Canister data is stored in canonical, \ - locale-neutral forms, so CONVERT it for the user rather than echoing the raw value. \ - Timestamps are almost always nanoseconds since the Unix epoch in UTC (IC time; divide \ - by 1e9 for seconds) — render them in the USER's time zone and date/number \ - conventions, not raw UTC nanoseconds. Physical quantities are usually SI/metric or an \ - app-defined unit — check `get_canister_api_doc` for the exact unit, then convert to the \ - user's locale for the measures that split US-customary vs metric: temperature (°C↔°F), \ - mass/weight (g,kg↔oz,lb), length/height/distance (cm,m,km↔in,ft,mi), and volume \ - (mL,L↔fl oz,US gal). Infer the user's locale and time zone from the conversation (their \ - language, where they are, the app) or ask when it matters; keep the raw value alongside \ - the converted one when precision matters (money, exact timestamps) or the source unit \ - is uncertain. Don't convert blindly — first establish the SOURCE unit (from \ - `get_canister_api_doc`, the field/entity name, or the schema), then convert.\n\n\ - `canister_query` (reads) and `canister_update_call` (writes) call a method with \ - textual Candid in/out: omit the identity args to call anonymously, or act AS your \ - account at an app. To act as an app account, identify the app by its \ - `derivation_origin` — the EXACT canonical origin Internet Identity derives its \ - principal from, which is NOT necessarily the visible website URL and must NEVER be \ - inferred from an ii-alternative-origins list. The identity-bearing tools \ - (canister_query, canister_update_call, get_app_principal, list_app_accounts, \ - get_canister_oql_schema) \ - take ONLY `derivation_origin`, NOT a website URL: a derivation origin is a stable \ - per-app value, so RESOLVE IT ONCE with `open_app` (or `resolve_app`) — which turn an \ - app name/URL into it under the guessed-domain gate — and reuse it across calls, rather \ - than re-resolving a URL every time on this stateless server. A short-lived (<=5 min) account \ - delegation is minted ON DEMAND from this connection's standing credential, no extra \ - sign-in. `get_app_principal` returns the principal without a call; `list_app_accounts` lists \ - the user's accounts (a default one plus any named ones), and canister_query / \ - canister_update_call / get_app_principal take an optional `account` (a name from that \ - list) — omit it for the default. Every identity result echoes `derived_for_origin` (the origin actually used) and \ - `requested` (what you passed), so a canonicalization mismatch is visible. If a principal, \ - account, or balance doesn't match what the user sees in their browser, the derivation \ - origin is wrong: re-resolve the app with `open_app`/`resolve_app` (don't guess an origin). The standing \ - credential is obtained when you connect \ - (authenticate via Internet Identity) and lasts for the session duration you choose when \ - connecting (up to 30 days); reconnect when it expires. \ - Internet Identity's consent screen asks the user to choose an access level, \ - \"Questions only\" or \"Actions & questions\". On a Questions-only session reads work, but \ - state-changing calls (canister_update_call) are rejected by the network — if one fails \ - that way, ask the user to reconnect and choose \"Actions & questions\".\n\n\ - Typical flow (acting FOR THE USER at an app): (0-2) `open_app(name-or-URL)` in ONE \ - call gives the `derivation_origin` AND the app's canisters (with `oql`/`api_doc_available` \ - flags) — pass the NAME the user said (well-known apps resolve \ - offline) or a URL you have, NEVER a domain guessed from the name (there is no on-chain \ - name→URL directory). If you want just one part, \ - `resolve_app(url)` does the origin, `discover_app_canisters(url)` the canisters; (3) \ - `list_app_accounts` — if there is more than one account, ask which to use and remember \ - it; (4) `get_app_principal` ONLY when you need the principal value itself (`canister_query` / \ - `canister_update_call` act as the account without pre-fetching it); (5) inspect the \ - canister with `get_canister_candid` — its `oql` flag says whether to read via OQL, \ - its `api_doc_available` flag whether `get_canister_api_doc` has a doc; (6) READ as the \ - user with `canister_query`, passing the `derivation_origin` (REQUIRED for OQL): use the \ - `oql` argument when `oql: true` (get the entity/field names from get_canister_oql_schema; \ - an anonymous OQL read is rejected for now, and a Candid `method` \ - query is REJECTED on an OQL canister), else a Candid `method` query; (7) ACT with \ - `canister_update_call`, passing `derivation_origin` + `account` to act as the \ - user.
