The REST endpoints in the rest of this section return rows. Some questions cannot be answered from rows: what a weapon does with a particular amplifier, enhancers, rings and a pill in front of it depends on efficiency, buff caps and decay, and arithmetic over the published stats will not match what the site shows.
Those calculations, and the lookups around them, are published as tools. They run the same services the website runs, so a setup calculated by an agent matches the setup page exactly.
Everything here is anonymous and read-only.
MCP
The preferred way in, if your client supports it:
https://api.entropiacentral.com/mcpStreamable HTTP, no authentication, no session to establish. Point Claude, ChatGPT or any MCP-capable client at that URL and the tools appear with their schemas. The server card is published at /.well-known/mcp/server-card.json.
The same tools over HTTP
For anything that can only fetch a URL:
GET /tools every tool, with its JSON Schema
GET /tools/{name}?argument=value run oneRepeat a parameter or comma-separate it for a list. Pass JSON for an object parameter. A parameter the tool does not declare comes back listed under ignoredParameters rather than being silently dropped.
curl "https://api.entropiacentral.com/tools/calculate_hunting_setup?weapon=ArMatrix%20LR-40&lifier=A105&creatures=Atrox%20Mature"Every tool answers in one shape:
{
"tool": "calculate_hunting_setup",
"columns": ["Creature", "Health", "Kills/Hour", "Time to Kill (s)", "Cost to Kill (PED)"],
"rows": [{ "Creature": "Atrox Mature", "Health": 1100, "Kills/Hour": 42.1 }],
"rowCount": 1,
"note": "Setup: weapon ArMatrix LR-40, amp A105. That setup gives DPS ..."
}Read the note. It says which items each name resolved to, what could not be placed in the setup, and which stats the wiki has no value for. A stat that is not recorded reads as zero in the data, and the note is the only thing that knows the difference.
What the tools cover
| Tool | Answers |
|---|---|
calculate_hunting_setup | A whole loadout: weapon, amplifier, attachments, enhancers, armour and plating, rings, healing, clothes, a pet buff and consumables. Returns DPS, DPH, DPP, efficiency, cost per shot and per hour, damage, range, durability, the resulting buffs, and cost to kill named creatures. |
find_ring_combo | Ring pairs, one per hand, whose combined effects meet what you asked for. |
find_wiki_item, get_wiki_item, list_wiki_items | One entry by name, everything about one entry, or a ranking of entries by a stat. |
query_globals, aggregate_globals | Individual tracked loots, or counts and totals grouped by type, creature, land area, avatar or period. |
resolve_avatar, get_avatar_profile | An avatar by name, tolerating misspellings, and their lifetime totals. |
query_pvp, aggregate_pvp | Recorded PvP kills. |
query_trade_messages, aggregate_trade_messages | In-game trade chat, deduplicated across reposts. |
resolve_event, get_event_standings, aggregate_event_globals, query_event_globals, get_event_teams | Competitions, their stages, standings and the globals that scored in them. |
search_documentation, search_guides | How Entropia Central works, and how Entropia Universe works. |
GET /tools is the current list. It is generated from the server, so it is never out of date.
Rules
Compare by running the calculator twice. Once per setup, then compare the results. Assembling the figures yourself from wiki stats will disagree with the site.
We hold no prices and no markup. No tool can tell you what an item is worth today. Trade chat is the closest thing, and it is what people asked for, not what anything sold for.
Rate limit: 60 requests per minute, per caller, across the MCP server and the tool endpoints. Exceeding it returns 429 with a Retry-After header.
