create_issue · Mantis MCP: Risk & Policy

WHAT IT DOES

What create_issue does on Mantis

AI agents use create_issue to create or update resources in Mantis — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mantis environment.

WHY IT NEEDS A POLICY

Why create_issue needs a policy

Creating an issue is a reversible write operation that adds structured data to the Mantis bug tracker. While it creates new records, it does not execute code, delete data, or move money, making it a Write-category action. Severity is medium because an AI agent misusing this could spam or pollute the issue database, but the data is retrievable and can be cleaned up.

From the tool's definition Tool name 'create_issue' and description stating it creates ('新增' = 'adds/creates') a Mantis issue. This is a write operation that creates new data in the issue tracking system.

Verdict

create_issue Rate-limited

create_issue stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
