Fix oversized images in Claude Code conversations by replacing them with placeholder text. Creates backups before changes.
AI agents use fix_image_issues to create or update resources in Claude Code Toolkit — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Claude Code Toolkit environment.
The tool modifies existing conversation data by replacing image content with placeholder text. While it does alter data, it is reversible because it explicitly creates backups before making changes, placing it in the Write category rather than Destructive. Misuse could result in loss of image context across conversations, hence medium severity.

Documented attack patterns abuse exactly the kind of access fix_image_issues gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Claude Code Toolkit, and nothing reaches the server without passing your rules. This is the rule we recommend for fix_image_issues:
{
"version": "1",
"default": "deny",
"tools": {
"fix_image_issues": {
"limits": [
{
"counter": "fix_image_issues_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}fix_image_issues 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.

Fix oversized images in Claude Code conversations by replacing them with placeholder text. Creates backups before changes. It is categorised as a Write tool in the Claude Code Toolkit MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Claude Code Toolkit MCP server in PolicyLayer and add a rule for fix_image_issues: 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 Claude Code Toolkit. Nothing to install.
fix_image_issues 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 fix_image_issues 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 fix_image_issues. 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.
fix_image_issues is provided by the Claude Code Toolkit MCP server (asifkibria/claude-code-toolkit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Claude Code Toolkit, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
