Execute Claude Code in headless mode to implement a feature
AI agents invoke execute_claude_code_feature to trigger actions in Obsidian Ai Curator. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool executes arbitrary code within the Obsidian vault environment. While not immediately destructive by design, executing code in headless mode creates significant risk of unintended consequences—file modifications, data corruption, or external API calls—if the AI agent misuses it. The blast radius is substantial because the code runs with the vault's permissions.
From the tool's definition Tool name 'execute_claude_code_feature' and description 'Execute Claude Code in headless mode to implement a feature' indicate execution of code with side effects.
Documented attack patterns abuse exactly the kind of access execute_claude_code_feature gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Obsidian Ai Curator, and nothing reaches the server without passing your rules. This is the rule we recommend for execute_claude_code_feature:
{
"version": "1",
"default": "deny",
"tools": {
"execute_claude_code_feature": {
"limits": [
{
"counter": "execute_claude_code_feature_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
} execute_claude_code_feature stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Execute Claude Code in headless mode to implement a feature. It is categorised as a Execute tool in the Obsidian Ai Curator MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Obsidian Ai Curator MCP server in PolicyLayer and add a rule for execute_claude_code_feature: 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 Obsidian Ai Curator. Nothing to install.
execute_claude_code_feature is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the execute_claude_code_feature 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 execute_claude_code_feature. 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.
execute_claude_code_feature is provided by the Obsidian Ai Curator MCP server (nwant/obsidian-ai-curator). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Obsidian Ai Curator, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
