format_file

Format a single file using .editorconfig rules

Accepts file system path (file_path); Single-target operation

Part of the Editorconfig MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

// WHEN AI AGENTS USE THIS TOOL

AI agents call format_file to perform operations in Editorconfig. While the risk category is not fully classified, applying a rate limit gives you visibility into how often the tool is called and prevents unexpected bursts of activity from autonomous agents.

// WHY ENFORCE A POLICY ON FORMAT_FILE

Applying a policy to format_file gives you an audit trail of every call an AI agent makes. Even for low-risk tools, visibility into agent behaviour helps you debug issues, optimise workflows, and maintain compliance with your organisation's security requirements.

// RECOMMENDED POLICY

Apply a rate limit to control usage and monitor for unexpected behaviour.

// FAQ

What does the format_file tool do? +

Format a single file using .editorconfig rules. It is categorised as a Other tool in the Editorconfig MCP Server, which means it performs auxiliary operations.

How do I enforce a policy on format_file? +

Add a rule in your Intercept YAML policy under the tools section for format_file. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Editorconfig MCP server.

What risk level is format_file? +

format_file is a Other tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit format_file? +

Yes. Add a rate_limit block to the format_file rule in your Intercept 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.

How do I block format_file completely? +

Set action: deny in the Intercept policy for format_file. 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.

What MCP server provides format_file? +

format_file is provided by the Editorconfig MCP server (editorconfig-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
