2 of 4D Documentation Viewer's 3 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.
PolicyLayer is an MCP gateway — it sits between your AI agents and 4D Documentation Viewer, and nothing reaches the server without passing your rules. These are the rules we recommend:
{
"clear_4d_docs_cache": {
"deny_if": [
{
"conditions": [],
"on_deny": "Blocked by default. Requires approval."
}
]
}
} Destructive tools should never be available to autonomous agents without human approval.
{
"get_4d_command_docs": {
"limits": [
{
"counter": "get_4d_command_docs_per_minute",
"window": "minute",
"max": 60,
"scope": "grant"
}
]
}
} Controls API costs and prevents retry loops from exhausting upstream rate limits.
Instant setup, no code required.
Other MCP servers with similar tools — same risk classification, starter policies for each.
Yes. The 4D Documentation Viewer server exposes 1 destructive tools including clear_4d_docs_cache. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.
3 tools across 3 categories: Destructive, Read, Write. 1 are read-only. 2 can modify, create, or delete data.
Register the 4D Documentation Viewer MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.
Deterministic rules across all 3 4D Documentation Viewer tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
Instant setup, no code required.
