get_resource Get Educational Resource ~448
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.
| Name | Type | Req | Description |
|---|---|---|---|
| author | string | – | Author pubkey (hex) to disambiguate if multiple resources share the same identifier |
| eventId | string | – | Nostr event ID (hex) for direct lookup. Alternative to identifier. |
| identifier | string | – | Resource identifier (d-tag). Use this for stable lookups. |
| language | string | – | Preferred language for labels (default: "de") |
| naddr | string | – | NIP-19 naddr from a search result — the preferred handoff to fetch full metadata. |
| relays | array | – | Restrict the lookup to specific relays — pass the relays a search found the result on. Only relays returned by list_relays (default or extra) are accepted, by full URL or short name (e.g. "oersi"). D… |

list_calendar_authors List Calendar Authors ~64
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_known_authors List Known Authors ~63
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_relays List Relays ~61
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
relay_list_get Get Relay List ~70
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.
| Name | Type | Req | Description |
|---|---|---|---|
| pubkey | string | – | Public key to fetch relay list for (defaults to connected signer) |
No output schema declared.

relay_stats Relay Statistics ~33
Get information about all selectable AMB relays (default and extra), including supported NIPs, relay name, and description.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
resolve_author Resolve Author Name to Pubkey ~317
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.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | number | – | Max candidates (1-25, default 10). |
| name | string | yes | Org or person name to resolve (e.g. "Jörg Lohrer"). |
No output schema declared.
No examples provided.
resolve_publisher Resolve Publisher/Creator Name to Canonical Metadata Spelling ~225
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.
| Name | Type | Req | Description |
|---|---|---|---|
| name | string | yes | Actor name as the user said it (e.g. "Lehreladen"). |
| relays | array | – | Restrict the lookup to specific relays. Only relays returned by list_relays (default or extra) are accepted, by full URL or short name (e.g. "oersi", "sodix"). Default: the default relay set. |
No output schema declared.
No examples provided.
search_calendar_events Search Calendar Events ~1,250
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.
| Name | Type | Req | Description |

| endBefore | number | – | Only events over by this Unix timestamp (inclusive: an event ending exactly then counts) |
| free | boolean | – | true: only events tagged free of charge (price 0). Events without a price statement are NOT returned, so leave it unset unless the user insists on free. false adds no filter. |
| geohash | string | – | Geohash prefix for location-based search |
| hashtags | array | – | Filter by hashtags (e.g., ["meetup", "nostr"]) |

search_content Search Educational Content (resources, articles, wikis, projects, measures, publications) ~1,067
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 a…

search_passages Grounded passage search (RAG) scoped by a spell ~1,123
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. kin…

search_resources Search Educational Resources ~822
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.
