WHAT IT DOES

What save_project_config does on Code MCP Server

AI agents use save_project_config to create or update resources in Code MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Code MCP Server environment.

RISK

Why save_project_config is rated Medium

This tool creates or modifies the .vscode-mcp.toml configuration file, which qualifies as Write category. Severity is high because modifying server configuration could grant an agent elevated capabilities (e.g., adding allowed_commands, altering security policies, or changing workspace behavior) with significant downstream impact, though the effect is reversible.

From the tool's definition save_project_config tool 'Save project-specific configuration to .vscode-mcp.toml' directly modifies a configuration file that controls the behavior of the MCP server and project operations (including command execution, file operations, and Git management as…

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs save_project_config safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Code MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For save_project_config, this is the rule to start with:

save_project_config Rate-limited

save_project_config 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.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "save_project_config": {
      "limits": [
        {
          "counter": "save_project_config_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Code MCP Server, apply this rule, and every save_project_config call is checked against it from then on.
