Tools 65 found in our last check

  • list_campaigns

    List all Argo campaigns the current grant token has access to, including the access level ("read" or "read+write") for each. Call this first when the user has not provided a campaign ID. Each entry includes both `campaignName` and `id` (shown inline as `[id: …]` and also in stru…

  • get_campaign

    Retrieve details of an Argo campaign (name, description, rule system, co-GMs).

  • create_campaign

    Create a new Argo campaign. The current user becomes GM and the calling token gains read+write access to the new campaign immediately (no re-consent needed). Requires the campaign.create OAuth scope, granted at consent time.

  • update_campaign

    Update a campaign's display name and/or description. Both fields optional — only supplied fields are changed; pass an empty string to clear the description. GMs and co-GMs can call this; rule-system swaps remain WebApp-only.

  • list_co_gms

    List the assistant GMs (co-GMs) of a campaign.

  • add_co_gm

    Send a user an assistant GM (co-GM) offer for a campaign. This does NOT add them immediately: the target must accept the offer before they become an assistant GM. Owner-only — the calling user must be the campaign's primary GM. Maximum 5 co-GMs per campaign.

  • remove_co_gm

    Remove a co-GM from a campaign. Owner-only or self-removal.

  • describe_mnemon_types

    Returns a catalog of all mnemon types, their type-specific fields, and the full valid relationship matrix (sourceType → label → targetType). Call this before create_mnemon or create_mnemon_relationship when you are unsure which type or label to use. A person is an NPC and a fact…

  • list_mnemons

    List mnemon (lore/memory) entries for an Argo campaign. Optional filters: `title` (case-insensitive substring on entry title only) and `type` (e.g. NPC, Location, Quest). To find entries by what they CONTAIN, use search_mnemons instead. Returns up to `limit` entries (default 100…

  • search_mnemons

    Full-text search across mnemon titles, tags, and body content (case-insensitive substring). Prefer this over list_mnemons when looking for entries by what they contain — e.g. "what do we know about the Red Oracle?". Each hit reports which fields matched (title/tags/content) and…

  • get_mnemon

    Get the full details of a specific mnemon entry (title, blocks, type properties). For a quest, `quest` holds its status, kind, playersCanTick, objectives and reward chips (with their ids), progress and reward totals, as the current user may see them — read objectives and rewards…

  • list_mnemon_relationships

    List the relationships of a mnemon entry, split into outgoing edges, incoming edges, and a flat list of linked entries (entryId/title/type/relationshipTypes). Use this to find members of a faction, allies/enemies of an NPC, etc.

  • create_npc_mnemons

    Create NPC mnemons (individual people). role is an optional free-text role or occupation. Use affiliationEntryIds to name the factions each NPC belongs to; the server projects them into MEMBER relationships. For a faction, guild or cult use create_faction_mnemons. Players may no…

  • create_faction_mnemons

    Create Faction mnemons (factions, guilds, cults, companies). Use memberNpcEntryIds to name each faction's NPC members; the server projects them into MEMBER relationships. Players may not call this — GM/co-GM only.

  • create_location_mnemons

    Create Location mnemons (places — cities, dungeons, taverns). Use create_mnemon_relationship with PARENT_OF to nest larger places under one another after creation. Players may not call this — GM/co-GM only.

  • create_quest_mnemons

    Create Quest mnemons: a header (status, kind, playersCanTick, hook, and giverId / locationId / parentQuestId links) and a body of objectives (with sub-objectives), reward chips, a Markdown background and GM-only gmNotes. The server builds the quest the Argo app shows from these.…

  • create_lore_mnemons

    Create Lore mnemons (world background, factions' beliefs, history). Players may not call this — GM/co-GM only.

  • create_archive_mnemons

    Create Archive mnemons (archived lore that is no longer current). Players may not call this — GM/co-GM only.

  • create_journal_mnemons

    Create Journal mnemons (log of in-world events). Players may not call this — GM/co-GM only.

  • create_session_summary_mnemons

    Create SessionSummary mnemons (the memory of one played session): the story as the Markdown body, plus a short recap shown as "Previously on". Players may not call this — GM/co-GM only.

  • create_custom_mnemons

    Create custom-typed mnemons (any free-form entry that doesn't fit the other types). Players may not call this — GM/co-GM only.

  • update_npc_mnemons

    Update typed/meta fields of NPC mnemons (visibility, tags, role, faction membership, etc.). An entry that is not an NPC fails its item; use update_faction_mnemons for a faction. Does NOT modify content blocks — use update_mnemons_content for that. Set visibility=PUBLIC on multip…

  • update_faction_mnemons

    Update typed/meta fields of Faction mnemons (visibility, tags, members). An entry that is not a Faction fails its item. Does NOT modify content blocks — use update_mnemons_content for that.

  • update_location_mnemons

    Update typed/meta fields of Location mnemons.

  • update_quest_mnemons

    Update Quest mnemons. A field left out is left as it is: status, kind, playersCanTick, hook, the giverId / locationId / parentQuestId links (an empty string removes one), and objectives, rewards, background or gmNotes, each of which replaces its part of the quest and keeps the r…

  • update_lore_mnemons

    Update typed/meta fields of Lore mnemons.

  • update_archive_mnemons

    Update typed/meta fields of Archive mnemons.

  • update_journal_mnemons

  • update_player_mnemons

  • set_quest_objective_state

    Tick, fail or reopen one objective of a quest by its id (get_mnemon's quest.objectives[].id), at any depth, without rewriting the quest. A GM sets any state. A player may only tick an objective they can see done, or undo that, and only while the quest's playersCanTick is on. Ret…

  • update_mnemons_content

    Edit the body content of one or more mnemon entries. Each item carries an entryId and an ordered list of ops (append, insertAfter, replace, remove) applied atomically per entry. Op content is authored as Markdown (headings, lists, quotes, code fences, bold/italic, links) — do NO…

  • create_mnemon_relationship

    Create a relationship between two mnemon entries. The label decides everything: its kind (containment or association) and how it reads (one_way or mutual) belong to the word itself — never send a per-edge override. All 16 labels: MEMBER (NPC ∈ Faction, mutual), ALLY (mutual), EN…

  • delete_mnemon_relationship

    Delete a relationship by id.

  • list_guild_members

    List the members of a guild (id, role, status, invitedAt, joinedAt).
