Capabilities

Tools 19

browse_educational_levels

List available educational levels (Primary, Secondary, Higher Education, etc.) with resource counts.

Discovered
browse_resource_types

List available learning resource types (Video, Course, Worksheet, etc.) with resource counts.

Discovered
browse_subjects

List available subjects/topics in the educational resource collection. Returns subjects with their labels and resource counts.

Discovered
find_community

Find Nostr communities (Communikey, kind 10222) matching a free-text topic — use for "welche Community/Gruppe beschäftigt sich mit …" questions. Each result's `pubkey` can be passed as the `community` parameter of search_content or search_calendar_events to scope a search to that community.

Discovered
get_resource

Retrieve a single piece of content by naddr (preferred — pass a search_content result's naddr), d-tag identifier, or event ID. naddrs of ANY content type from search_content work (resources, articles, wikis, projects, measures, publications); non-resource kinds return the same shape as their search results. Bare identifier/eventId lookups (no naddr) always resolve the full educational-resource metadata (kind 30142), including creator/publisher and educational properties. get_resource is never license-filtered: a learning resource carries license ({id, label}, or null when unlicensed) and accessLevel ("full" for Creative Commons, Public Domain and free software/documentation licenses, and DINI-AG-KIM license types that resolve to one of these; "metadata-only" otherwise). Only accessLevel:"full" resources have indexed fulltext, snippets and passages — present a "metadata-only" resource by its title, description, license and link, never quoted beyond its metadata, and always name the license and the creator/publisher. openLicense is kept for compatibility (deprecated; use accessLevel). When presenting the resource, render a markdown link the user can open: prefer its sourcePage (the original source page); fall back to url (the edufeed viewer) only when sourcePage is absent.

Discovered
list_calendar_authors

List known calendar event authors loaded from configured follow sets (NIP-51 kind 30000). Returns author names, pubkeys, and NIP-05 identifiers. Use the returned pubkeys with search_calendar_events(authors: [...]) to filter events by author.

Discovered
list_known_authors

List known educational resource authors loaded from configured follow sets (NIP-51 kind 30000). Returns author names, pubkeys, and NIP-05 identifiers. Use the returned pubkeys with search_resources(authors: [...]) to filter resources by author.

Discovered
list_relays

List the configured AMB relays. defaultRelays are searched on every query; extraRelays hold different corpora (e.g. the OERSI aggregation) and are only searched when a search/get tool call passes them in its relays parameter.

Discovered
relay_list_get

Get a user's NIP-65 relay list (kind 10002). Returns read and write relays for the specified pubkey. If no pubkey provided, uses the connected signer's pubkey.

Discovered
relay_stats

Get information about all selectable AMB relays (default and extra), including supported NIPs, relay name, and description.

Discovered
resolve_author

Resolve an org or person NAME to candidate pubkeys using the relay's kind-0 author-profile index (NIP-50 search). Use this to answer name-driven content questions like "recent articles and resources of Jörg Lohrer": call resolve_author(name), pick the best candidate, then pass its pubkey to search_content({ authors: [pubkey], ... }) (and/or search_calendar_events) to fetch that author's content. Returns several candidates ranked by relevance so you can disambiguate. This indexes authors who have published content here — distinct from list_known_authors, which lists hand-curated follow sets. NOTE: this resolves only kind-0 author profiles. It does NOT resolve a community's identifying pubkey — a community is defined by a kind-10222 event and frequently has no kind-0 at all. To list content shared into a community you need that community pubkey (a Nostr identifier, e.g. from the community's spec/naddr), which you pass to the `community` param of search_content / search_calendar_events. resolve_author CAN, however, find a community's posting account (e.g. a "…-Termine-Bot") when that account has a kind-0; querying that pubkey via authors:[...] returns the content it published. A wrong pick simply yields empty results.

Discovered
resolve_publisher

Resolve an actor name (organization or person) to the EXACT spelling used in the AMB metadata, so it can be passed to the publisherName/creatorName filters of search_resources. Those filters are exact full-string matches (case-insensitive), so a guessed spelling like "Lehreladen" silently misses the stored "LEHRE LADEN". This tool free-text searches the name and returns the similar publisher/creator names found in the corpus, with the field they appear in and a resource count. Distinct from resolve_author, which resolves Nostr signing accounts (kind-0 profiles) to pubkeys — metadata publishers usually have no Nostr account at all.

Discovered
search_calendar_events

Search for NIP-52 calendar events (date-based and time-based). Supports temporal filters (start/end time ranges), geohash location filtering, hashtag filtering, and the edufeed educational attributes (free, registrationRequired, attendanceMode, educationalLevel). Returns events from the configured calendar relay. TIME SEMANTICS (NIP-52): `start`/`end` are the raw tags — `end` is EXCLUSIVE and is omitted for one-day and instantaneous events, so never read a missing `end` as "unknown". Use `effectiveEnd` (Unix seconds when the event is over), `allDay` (31922: whole days, no clock time) and `lastDay` (all-day events: the inclusive last calendar day). Times of 31923 events are in `startTzid`/`endTzid`. ATTRIBUTES: `attributes` carries registration, price (free = amount 0), attendance mode (online/offline/mixed) and Bildungsstufe; a missing field means "no statement", never "no" or "not free". AUTHOR: every event has `author` {name, bot}; `bot: true` marks an automated account such as an event mirror or crawler — group or de-emphasise those unless the user asks for imports. Operators may hide bulk sources by default (see `hiddenSources` in the result); pass includeHiddenSources: true to see them. When presenting an event to the user, render it as a markdown link: prefer the event `url` (the edufeed-app viewer at <base>/<naddr>, which shows fuller details) over `sourcePage` (the original external event page). Never construct an naddr or viewer URL yourself — use the `naddr`/`url` fields as returned.

Discovered
search_content

Topic search across ALL content types on the relay in one ranked call: educational resources (kind 30142), long-form articles/blogs (30023), wikis (30818), projects (30143), measures (30144), and NKBIP-01 publications (30040 indices + 30041 sections — scientific articles, books). Results are interleaved and ranked by semantic passage match, and each carries the matched passage ("snippet") when available — use it to answer the user, not just list links. Every learning resource is returned by default, whatever its license; each resource result carries license ({id, label}, or null when unlicensed) and accessLevel ("full" for Creative Commons, Public Domain and free software/documentation licenses, and DINI-AG-KIM license types that resolve to one of these; "metadata-only" otherwise). Snippets and passages exist only for accessLevel:"full" resources — present a "metadata-only" resource by its title, description, license and link, never quoted beyond its metadata, and always name the license and the creator/publisher. licenseFilter narrows the results: "open" = CC0, Public Domain, CC BY, CC BY-SA, their DINI-AG-KIM license-type equivalents, and free software/documentation licenses (GPL, LGPL, AGPL, GFDL, MIT, Apache 2.0, BSD); "cc-any" = all of "open" plus every other Creative Commons license, incl. KIM non-commercial/no-derivatives; "any" = also unlicensed and all-rights-reserved resources. The other content types carry no license and are always included. This is the tool for DISCOVERY intent — the user wants materials to browse ("finde/suche/empfiehl Materialien zu X"): present the items. For QUESTION intent — the user wants an answer built from the content ("wie/warum/was hilft bei X?") — prefer search_passages, which returns quotable fulltext passages with citations; this tool then supplements the answer with browsable links. Each result carries eventAuthor (the Nostr signer who uploaded the event — often an aggregator) plus, for resources, creator/publisher (who actually made and published the resource); these can differ, so do not treat eventAuthor as the publisher. For full metadata (license, dates, complete entity lists) pass a result's naddr to get_resource. Publication facets ride inside the query string as NIP-50 field filters: append type:academic, doi:10.1234/abcd.5678, keywords:<term>, or partOf:30143:<pubkey>:<d> ("publications of a project") to the query — the relay resolves them server-side. When presenting results to the user, render each as a markdown link so they can open it directly — prefer sourcePage (the original external source page, present on most resources and on projects/measures/publications), then url, then naddr. For upcoming events on the same topic, follow up with search_calendar_events.

Discovered
search_passages

THE DEFAULT TOOL FOR QUESTION-SHAPED QUERIES ("wie/warum/was hilft bei X?", "how do I…?"): retrieves the best-matching fulltext passages from the corpus and returns them with citations (source resource, page, heading, source URL) — answer the user FROM the passages and cite each source. (For discovery intent — "finde/empfiehl Materialien" — use search_content instead, or afterwards to offer browsable links.) Keep `question` topic-only. Ranking is hybrid keyword+vector, so phrase the question as a topical statement that names the subject and the target group ("Friedenserziehung in der Grundschule: Einstieg in das Thema Frieden mit Kindern"), not as the user's literal sentence ("Wie kann ich …?"). Results are capped at two passages per document; a passage with only a snippet and no text has no fulltext yet — say so instead of guessing. Passages come from learning resources under Creative Commons, Public Domain and free software/documentation licenses, and DINI-AG-KIM license types that resolve to one of these and from articles, wikis, publications and the other content kinds. Other matching learning resources appear in `metadataOnlyMatches` (naddr, title, license, creator/publisher, sourcePage) without text, because their license does not permit quoting — point the user to them by title, license and link, never quote or paraphrase them as content. Cite the license and the creator/publisher with every learning-resource passage. licenseFilter narrows learning resources: "open" = CC0, Public Domain, CC BY, CC BY-SA, their DINI-AG-KIM license-type equivalents, and free software/documentation licenses (GPL, LGPL, AGPL, GFDL, MIT, Apache 2.0, BSD); "cc-any" = all of "open" plus every other Creative Commons license, incl. KIM non-commercial/no-derivatives (normally no metadataOnlyMatches); "any" = also unlicensed and all-rights-reserved resources, as metadataOnlyMatches. Scope is required but simple: with no source restriction from the user, pass the content kinds (e.g. kinds:[30142] for educational resources, [30040,30041] for publications, [30023] for articles). Route source restrictions ("nur Content von X") into the scope parameters: a metadata publisher (most organisations — resolve_publisher finds the exact spelling) goes into `search` as a QUOTED field filter, e.g. search:'publisher.name:"LEHRE LADEN"' (unquoted multi-word names match nothing); a Nostr signing account (resolve_author → pubkey) goes into `authors`. A published grimoire spell (kind 777, nevent or event id) can replace inline scope entirely; the response carries the canonical spell for whatever scope was used — publish it (e.g. via grimoire) to make the scope reusable. Spells may use $me/$contacts; they resolve to the calling user (pass `me` if the transport is anonymous). Scope materialization (tag/search/community spells) runs against the primary relay only; the passage search itself fans out to every selected indexed relay. Fails rather than widening scope: an empty scope, unreachable relay (relay_unreachable — tell the user to retry), or unreachable index is a typed error, never a silently unscoped search.

Discovered
search_resources

Search for educational resources (learning materials, courses, videos, etc.) using full-text search and metadata filters. Returns resources matching the query from the AMB relay. Every learning resource is returned by default, whatever its license; each result carries license ({id, label}, or null when unlicensed) and accessLevel ("full" for Creative Commons, Public Domain and free software/documentation licenses, and DINI-AG-KIM license types that resolve to one of these; "metadata-only" otherwise). licenseFilter narrows the results: "open" = CC0, Public Domain, CC BY, CC BY-SA, their DINI-AG-KIM license-type equivalents, and free software/documentation licenses (GPL, LGPL, AGPL, GFDL, MIT, Apache 2.0, BSD); "cc-any" = all of "open" plus every other Creative Commons license, incl. KIM non-commercial/no-derivatives; "any" = also unlicensed and all-rights-reserved resources. When citing a resource, always name its creator and publisher. NOTE: the metadata filters (publisherName, creatorName, subjectLabel, resourceTypeLabel, educationalLevelLabel) are EXACT full-string matches against the stored metadata (case-insensitive) — not fuzzy or substring searches. A guessed spelling silently returns 0 results; use resolve_publisher to find the canonical actor spelling first. On a zero-match actor filter the response includes actorCandidates with similar spellings to retry with.
