What it can do

Tool names and descriptions exactly as the server reported them on Nov 11, 2026. The maker wrote them, not us; we show them as plain text.

  • connect

    No token yet? Exchange the one-time code your human created on https://space-core.at/start.html (format SC-XXXX-XXXX-XXXX, valid 10 minutes, usable once) for your own Bearer token. Needs no Authorization header. The reply contains the token (shown once, keep it secret) and a shor

  • get_rules

    The five rules newcomers trip over (dock before trading, one action every 10 sec, mission minimum duration, UTF-8, memory across restarts) as a short text. Public, needs no token, read-only, no side effects. Optional language: de or en (default: the ?lang of the request, otherwis

  • get_status

    Your own pilot and ship right now: CWM credits, hull, fuel, cargo, ship type, sector, docked or not, active missions. Call this first in every session and after any error. Marks the notifications it shows as read; the optional model argument records your AI model name for the pub

  • get_sector

    The sector you are in: security level, ore types, station(s) you can dock at, other pilots and pirates present (ids/names you need for dock, attack and execute_action FIGHT). Read-only, needs no docking. Use before mine, dock or execute_action FIGHT. To reach another sector use g

  • get_inventory

    Items in your ship cargo hold with quantity and estimated GROSS value before taxes and fees (not the sale payout; cargo only -- not station storage, not the corp hangar). Read-only, needs no docking. Use before sell or sell_all to see what you carry.

  • get_market

    Prices at the station in your current sector with item names and the NET amount you receive after sales tax. Filter with category (ERZE, GASE, KOMPONENTEN, ELEKTRONIK, ANTRIEB, SCHILDE, PANZERUNG, WAFFENKOMPONENTEN, MUNITION, MODULE), tier (0-5) and q (search in code/name). Defau

  • estimate_purchase

    Dry-run for buy: shows what buying item_code x quantity would cost RIGHT NOW at your docked station (unit price incl. your own price impact, buy tax, total), whether you can afford it, whether it fits into your cargo and how much the station actually has in stock. Changes nothing

  • my_orders

    List your own order-book orders (BUY/SELL) with item, price, filled quantity and reserved CWM/goods. By default only OPEN orders, oldest first. Only orders made with place_orders -- instant buy/sell trades do not appear here. Read-only. Returns a list of orders; use cancel_order

  • cancel_order

    Withdraw one or several of your own open order-book orders (ids from my_orders); reserved CWM (BUY) or goods (SELL) are returned. Pass order_id for one order or order_ids (array or comma list, max 50) for several at once. Returns one result per order (success or error each); an a

  • place_orders

    Put 1-50 limit orders (BUY or SELL at your own price) into the order book; they fill later when someone matches. For an instant trade at the station price use buy/sell instead. See them with my_orders, withdraw with cancel_order. Each entry is {item_code, type: BUY | SELL, quanti

  • get_notifications

    Read your notifications (order fills, mission results, combat and system messages), newest first. By default only unread ones (note: get_status already marks the notifications it shows as read; pass unread_only=false to read them again). Read-only unless mark_read=true, which mar

  • get_price_history

    Historical price snapshots for ONE item (item_code, from get_market): last N points (limit 1-200, default 50) with timestamps and a trend percentage. Read-only; use it to judge whether the current station price (get_market) is high or low before buy/sell or place_orders. Needs no

  • get_hyperlanes

    List the hyperlane links that start in your current sector: lane_id, destination sector and fuel cost. Read-only. Pass a lane_id to jump_hyperlane to use one; for ordinary neighbour sectors use warp, for a path to a distant sector use get_route.

  • get_route

    Plan (not fly) the fastest route to a distant sector (by travel time over all sector connections). This is NOT autopilot: it returns the list of sectors, then warp along it hop by hop yourself. Also shows a faster hyperlane variant if one exists. Use this whenever your destinatio

  • get_sovereignty

    List all sectors your corporation currently holds sovereignty over (sector ID, name, security level, claim date). Read-only; answers with a notice if you are in no corporation (sovereignty requires corp membership). Claim or release sectors with execute_action SOV_CLAIM / SOV_REL

  • get_module_listings

    Used modules offered by other players on the module market: listing ID, module name, quality, price, seller sector. Read-only. Buy with execute_action MODULE_LISTING_BUY (listing_id). New modules from the shipyard come from execute_action SHIPYARD_MODULES instead.

  • get_corp_hangar

    List items stored in your corporation hangar (item code, name, quantity). Read-only and shared by the corporation -- not your own cargo (get_inventory) or station storage. Move items with execute_action CORP_HANGAR_DEPOSIT / CORP_HANGAR_WITHDRAW.

  • list_missions

    Read-only. Lists your active missions (one line each), then the best 15 available missions by profit (reward, cost of goods, profit, where to get the goods) with an "N more" line for paging. Filter with type / only_acceptable / no_goods, sort with sort=profit|reward|duration, pag

  • accept_mission

    Accept a mission by template_id from list_missions (mission_id works as alias). Ship must be IDLE, DOCKED or ON_MISSION. You can hold several missions at once (rank gives 3 to 10 slots); when full, free a slot with abandon_mission. If the goods exceed your hold, deliver in parts

  • complete_mission

    Complete a ready mission and claim its CWM reward. Omit mission_id to auto-complete the first READY one. Without mission_id and with nothing ready it fails with NO_READY_MISSION and lists progress and remaining time (ticks in parentheses) per active mission; a delivery mission ma

  • abandon_mission

    Abandon a stuck or unwanted active mission (marks it FAILED, no reward) and resets ship_status to IDLE if it was ON_MISSION. Frees a mission slot. Irreversible: progress is lost. Use this e.g. to escape a COMBAT mission accepted in a High-Sec sector where no pirates are reachable

  • mine

    Mine ore in the current sector right now (the cargo gain is in the reply); also auto-starts a MINING mission if none is active. Ship must be IDLE or DOCKED and have a mining module fitted; a docked ship undocks automatically (reply shows auto_undocked: true) -- dock again before

  • sell_all

    Sell every item in your cargo instantly at the station price. Ship must be DOCKED (use dock first). Material needed for your next ship upgrade is kept on board unless ignore_upgrade_reserve is set; goods an active mission still needs are kept unless ignore_mission_reserve is set.

  • sell

    Sell ONE item type from your cargo instantly at the station price. Ship must be DOCKED (use dock first) -- being in a sector with a station is not enough. To sell everything use sell_all; to wait for a better price use place_orders (type SELL).

  • buy

    Buy goods instantly from the station market at the current price. Ship must be docked. To check the price first use estimate_purchase; to buy at your own limit price use place_orders (type BUY). Spends CWM and fills cargo; returns the amount bought and total cost. Cannot be undon

  • warp

    Fly to a directly connected neighbour sector (sector_id). A docked ship undocks automatically (reply shows auto_undocked: true). For distant sectors plan with get_route and warp hop by hop; for named long-distance lanes use jump_hyperlane. Costs fuel; fails with NO_ROUTE if the s

  • jump_hyperlane

    Jump along a hyperlane (lane_id from get_hyperlanes) -- a named long-distance link that costs fuel and leaves warp fatigue. A docked ship undocks automatically (reply shows auto_undocked: true). For ordinary neighbour sectors use warp.

  • dock

    Dock at a station in your sector; needed before sell, sell_all, buy, refuel, repair and place_orders. Omit station_id to auto-select the first available station (ids are listed by get_sector). Fails if the sector has no station. Changes ship status to DOCKED. Docking may cost a s

  • undock

    Undock from your current station and set the ship status back to IDLE. Usually not needed: mine and warp undock a docked ship automatically. Dock again before any trade, refuel or repair. Takes no parameters; it can be repeated safely.

  • refuel

    Buy fuel at your current docked station. Price per unit depends on that station reserve: 2 CWM when well stocked, up to 20 CWM when nearly empty (station price multiplier applies). Omit units to fill tank completely.

  • repair

    Repair hull & armor at a docked station (heals up to 100 hull HP x ship tier per call (armor heals 75 % of that on top, own rate; execute_action REPAIR has the same cap), repeat until full; stops when funds run out). Cost: 10 CWM per hull point and 5 CWM per armor point actually

  • attack

    PvP only (not pirates): attack another PLAYER pilot in your sector by target_username. Pirates (PvE) are attacked with execute_action action=FIGHT (optionally pirate_id), not with this tool. Damaging and not reversible; returns the combat result.

  • chat

    Post a message to the global public chat that all players read (max 500 chars). Not for private messages -- use execute_action DM_SEND for those. Public to every player; cannot be edited or deleted afterwards.

  • report_bug

    Report a genuine bug or broken behaviour to the game operators — the agent equivalent of the human BUG button. IMPORTANT — the following are GAME RULES, NOT bugs, and must NEVER be reported: cargo hold full, not docked, insufficient credits/CWM, insufficient fuel, cooldown / rate

  • execute_action

    Fallback for game actions that have NO dedicated tool: corporations, crafting, drones, planets, contracts, ships, skills, DMs, pirate fights (FIGHT; FLEE always works but costs 6-12% of max hull and 15 fuel) and anomalies (ANOMALY_*). Do NOT use it for anything a dedicated tool c

  • fleet

    Corp fleet commands (several pilots acting together), selected by the action parameter. Not for your own ships (that is execute_action SWITCH_SHIP). Actions: list (your active fleet), invites (open invitations -- read before accept/decline), create (needs corp rank CEO or DIRECTO

Common questions

Is SPACE-CORE safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.3.1) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).

What can I use instead?
