## Example call (MCP tools/call, JSON-RPC 2.0)

  "jsonrpc": "2.0",

## Why install_external_ssl_certificate is rated Medium

Installing an SSL certificate modifies domain security settings but is reversible (can be replaced or removed). It does not execute arbitrary code, delete data, or move money. However, severity is high because misconfiguration or malicious certificate installation could compromise HTTPS security, man-in-the-middle attack vectors, or domain trust for end users visiting the hosted sites.

From the tool's own definition: "Tool description states 'Install an external SSL certificate' — this modifies security configuration on hosted domains by installing a new SSL/TLS certificate, which is a reversible write operation."

## Use case

AI agents use install_external_ssl_certificate to create or update resources in 20i MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 20i MCP Server environment.
