AI agents use update_repo to create or update resources in Komodo — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Komodo environment.
The tool modifies repository configuration or content but does not delete or destroy data (which would be Destructive), nor does it execute arbitrary code (Execute). It appears to update repository state within the Komodo platform, making it a Write operation.
From the tool's definition Tool name 'update_repo' indicates modification of repository data. Sibling tools include 'create_repo', 'create_build', 'create_deployment', suggesting this server manages DevOps infrastructure resources.
Documented attack patterns abuse exactly the kind of access update_repo gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Komodo, and nothing reaches the server without passing your rules. This is the rule we recommend for update_repo:
{
"version": "1",
"default": "deny",
"tools": {
"update_repo": {
"limits": [
{
"counter": "update_repo_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_repo 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.

update_repo. It is categorised as a Write tool in the Komodo MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Komodo MCP server in PolicyLayer and add a rule for update_repo: 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 Komodo. Nothing to install.
update_repo 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 update_repo 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 update_repo. 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.
update_repo is provided by the Komodo MCP server (myrikld/komodo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Komodo, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
