AI agents use github_create_issue to create or update resources in Sage MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sage MCP environment.
This tool creates a new issue, which is a reversible write operation. Issues can be created, and if mistakenly created, can be deleted or closed. The severity is medium because an agent could spam or create misleading issues, but the blast radius is limited to the target repository and the action is undoable.
From the tool's definition Tool name 'github_create_issue' and description 'Create a new issue in a repository' indicate creation of new data in a GitHub repository.
Documented attack patterns abuse exactly the kind of access github_create_issue gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sage MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for github_create_issue:
{
"version": "1",
"default": "deny",
"tools": {
"github_create_issue": {
"limits": [
{
"counter": "github_create_issue_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}github_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.
Free to start. No card required.
Create a new issue in a repository. It is categorised as a Write tool in the Sage MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Sage MCP server in PolicyLayer and add a rule for github_create_issue: 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 Sage MCP. Nothing to install.
github_create_issue 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 github_create_issue 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 github_create_issue. 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.
github_create_issue is provided by the Sage MCP server (sagemcp/sagemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
