Cancel one of your ship buy orders and refund the escrow (Refunds the full escrowed amount (price + sales tax). Works from anywhere. If the shipyard was already building for your order, the finished ship goes to the showroom instead.)
| Name | Required | Description | Default |
|---|---|---|---|
| order_id | Yes | ID of the buy order to cancel (use view_ship_buy_orders to see your orders) | |
| session_id | Yes | Your session ID from login/register |

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description goes beyond the minimal readOnlyHint=false annotation by disclosing specific behavioral outcomes: full refund of escrow (price + sales tax), remote operation, and the showroom handling if the ship was already under construction. This is rich, useful context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, tightly packed sentence with a parenthetical detail section. Every clause adds value: the main action, the refund mechanics, the remote usability, and the edge case. No filler or redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple mutation tool with two well-documented parameters, the description covers the main outcomes and an important edge case. With no output schema, it does not need to detail return values, and it is complete enough for an agent to invoke correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with both parameters having descriptions (order_id and session_id). The main description adds no additional parameter-level semantics beyond what the schema provides, so the baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb-resource pair ('Cancel one of your ship buy orders') and clearly states the associated refund behavior. It distinguishes itself from sibling tools like cancel_order, cancel_commission, and cancel_ship_listing by explicitly targeting ship buy orders.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear context for when to use the tool ('Works from anywhere') and implicitly indicates it is the tool for canceling ship buy orders. However, it does not explicitly name alternatives or state when not to use it, so it falls short of a 5.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Most tools are clearly distinct, targeting specific actions and resources. A few overlaps exist (e.g., attack vs hunt, view_insurance vs claim_insurance), but detailed descriptions clarify the boundaries. The scale makes selection harder, but each tool has a clear purpose.
The majority use a consistent verb_noun snake_case pattern (e.g., create_buy_order, get_cargo, accept_mission). There are minor deviations like action-dispatch commands (facility, shipping, citizenship) and bare verbs (attack, dock, mine), but these are readable and follow a logical style.
With 212 tools, the server far exceeds any reasonable scope for an MCP. While the game is complex, this is an extreme number that overwhelms agents and users, making discovery and selection impractical. The calibration considers 25+ already too many, and 212 is extreme.
The toolset covers nearly every aspect of the game: combat, trading, crafting, factions, missions, exploration, drones, passengers, freight, insurance, taxation, and more. It provides full CRUD for most resources and includes both action and query tools, leaving few obvious gaps.
