WHAT IT DOES

What install_skill does on Salesforce MCP Server

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

THE RISK

Why install_skill needs a policy

This tool performs a reversible file write operation—it creates or updates a skill documentation file in the project directory. It does not execute code against Salesforce, delete data, or trigger external operations with unpredictable side effects.

From the tool's definition The tool creates or modifies a file in the `.claude/skills/salesforce/SKILL.md` location by installing guidance documentation.

POLICY

How to control install_skill

PolicyLayer is an MCP gateway — it sits between your AI agents and Salesforce MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for install_skill:

policy.json

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

install_skill 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.

Create a free account and register Salesforce MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
