Set custom passthrough metadata on an issue. Core issue fields are protected.
AI agents use storybloq_issue_meta_set to create or update resources in Storybloq — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Storybloq environment.
This tool creates or modifies metadata on issues reversibly. It is a Write operation because it changes data state (metadata) but the operation is not destructive—metadata can be updated or removed. Severity is medium because misuse could corrupt issue tracking metadata or inject malicious data into the issue system, affecting project context integrity, but the protection of core fields limits the blast radius.
From the tool's definition Tool description states 'Set custom passthrough metadata on an issue', which is a direct modification operation. The phrase 'Core issue fields are protected' indicates this is a constrained write that modifies issue metadata but not core fields.
Documented attack patterns abuse exactly the kind of access storybloq_issue_meta_set gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Storybloq, and nothing reaches the server without passing your rules. This is the rule we recommend for storybloq_issue_meta_set:
{
"version": "1",
"default": "deny",
"tools": {
"storybloq_issue_meta_set": {
"limits": [
{
"counter": "storybloq_issue_meta_set_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}storybloq_issue_meta_set 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.

Set custom passthrough metadata on an issue. Core issue fields are protected. It is categorised as a Write tool in the Storybloq MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Storybloq MCP server in PolicyLayer and add a rule for storybloq_issue_meta_set: 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 Storybloq. Nothing to install.
storybloq_issue_meta_set 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 storybloq_issue_meta_set 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 storybloq_issue_meta_set. 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.
storybloq_issue_meta_set is provided by the Storybloq MCP server (storybloq/storybloq). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
