AI agents use create_print_job to create or modify resources in SimplyPrint: 3D Print Farm Management. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call create_print_job repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach SimplyPrint: 3D Print Farm Management.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Start a print job on one or more printers. File source is exactly one of: file_id (API file hash from upload), filesystem (user-file uid), queue_file (existing queue item id), reprint (previous print-job id), or next_queue_item=true (auto-pick the next matching queue item per printer, deduplicated across printers). Supports PRINT_JOB custom fields (shared and per-printer). Auto-starts when the account's autostartPrints setting is on (default).. It is categorised as a Write tool in the SimplyPrint: 3D Print Farm Management MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the SimplyPrint: 3D Print Farm Management MCP server in PolicyLayer and add a rule for create_print_job: 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 SimplyPrint: 3D Print Farm Management. Nothing to install.
create_print_job is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_print_job 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.
Set action: deny in the PolicyLayer policy for create_print_job. 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.
create_print_job is provided by the SimplyPrint: 3D Print Farm Management MCP server (https://simplyprint.io/api/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
