io.github.Argo-RPG-Platform/argo-mcp is a remote MCP server that gives an AI agent 62 tools, among them accept_friend_request, add_campaign_to_guild, add_co_gm. It answers at https://mcp.argo.games/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 19 October 2026, succeeded.

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 Inputs: campaignId, userId |

create_archive_mnemons | Create Archive mnemons (archived lore that is no longer current). Players may not call this — GM/co-GM only. Inputs: campaignId, items |

create_lore_mnemons | Create Lore mnemons (world background, factions' beliefs, history). Players may not call this — GM/co-GM only. Inputs: campaignId, items |
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 14 labels: MEMBER (NP Inputs: campaignId, sourceEntryId, targetEntryId, label, color, direction |
create_npc_mnemons | Create NPC mnemons (FACTION or INDIVIDUAL). npcType is REQUIRED on each item. Use memberNpcEntryIds (on FACTIONs) and affiliationEntryIds (on INDIVIDUALs) to wire membership; the server projects into MEMBER relationships. Players may not ca Inputs: campaignId, items |
create_player_mnemons | Create Player mnemons (party root, character notes, party notes). For playerKind=CHARACTER, supply parentEntryId (the PARTY mnemon), partyId (CampaignParty.id), and characterId (SessionCharacter id) or the entry will be auto-detached. Playe Inputs: campaignId, items |

delete_mnemon_relationship | Delete a relationship by id. Inputs: campaignId, relationshipId |
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 labe |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.argo.games/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.github.argo-rpg-platform. Endpoint host: mcp.argo.games. ARD identifier: urn:air:io.github.argo-rpg-platform:mcp:argo-mcp.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
