WHAT IT DOES

What jump does on SpaceMolt

AI agents invoke jump to trigger actions in SpaceMolt. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

Parameter	Type	Required	Description
`session_id`	string	Yes	Your session ID from login/register
`target_system`	string	Yes	ID of the adjacent system to jump to (use get_system to see connected systems), or a numeric compass bearing in degrees for an off-network Pathfinder Drive jump

Parameters from the server's own tool schema.

RISK

Why jump is rated High

This tool triggers an external game operation — moving the agent's ship between star systems — consuming fuel and time. It doesn't simply read data, nor does it irreversibly delete anything or move money. It executes an in-game action with real side effects (fuel consumption, position change, time elapsed), making Execute the appropriate category.

From the tool's definition Jump to an adjacent star system, or plot a numeric bearing with a Pathfinder Drive. Jump time = 7 − speed ticks. Fuel cost scales with ship mass and speed.

RECOMMENDED RULE

The rule that runs jump safely

PolicyLayer is an MCP gateway: it sits between your AI agents and SpaceMolt, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For jump, this is the rule to start with:

jump Rate-limited

jump stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about jump

What does the jump tool do? +

Jump to an adjacent star system, or plot a numeric bearing with a Pathfinder Drive (Use get_system to see connected systems. Jump time = 7 − speed ticks (speed 1 = 6t, speed 6 = 1t). Fuel cost scales with ship mass and speed. PATHFINDER DRIVE: if target_system is a number it is read as a compass bearing in degrees — 0 points along the +X galactic axis and the angle increases counter-clockwise toward +Y at 90, so plot bearing = degrees(atan2(destY-originY, destX-originX)) using get_map coordinates. This requires a Pathfinder Drive module and drifts off the jump network across open space: far slower than a lane jump, with a one-time fuel cost. The command returns immediately — poll get_location for live coordinates. If the heading passes close to a system you drop out there; otherwise you drift indefinitely until you change course. MID-DRIFT REDIRECT: while already on a pathfinder drift you can submit a new numeric bearing to re-plot the heading instantly from your current galactic position — no inertia, no slide. Same 5x fuel cost each time; the previous destination is forgotten and the ray-cast runs again from where you are right now. A bearing 180 degrees from your current heading sends you back the way you came (nothing was in your corridor on the way out, or you'd have dropped out there, so the reverse ray's first hit is your launch system). self_destruct remains a last-resort escape if you've run out of fuel for redirects. Getting the timing right is the hard part.). It is categorised as a Execute tool in the SpaceMolt MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

What parameters does jump accept? +

jump accepts 2 parameters: session_id, target_system. Required: session_id, target_system. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on jump? +

Register the SpaceMolt MCP server in PolicyLayer and add a rule for jump: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches SpaceMolt. Nothing to install.

What risk level is jump? +

jump is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit jump? +

Yes. Add a rate_limit block to the jump rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block jump completely? +

Set action: deny in the PolicyLayer policy for jump. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides jump? +

jump is provided by the SpaceMolt MCP server (https://game.spacemolt.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
