55 of WA MCP's 62 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 WA MCP, and nothing reaches the server without passing your rules. These are the rules we recommend:
{
"wa_clear_chat": {
"deny_if": [
{
"conditions": [],
"on_deny": "Blocked by default. Requires approval."
}
]
}
} Destructive tools should never be available to autonomous agents without human approval.
{
"wa_archive_chat": {
"limits": [
{
"counter": "wa_archive_chat_per_hour",
"window": "hour",
"max": 30,
"scope": "grant"
}
]
}
} Prevents bulk unintended modifications from agents caught in loops.
{
"wa_check_number_exists": {
"limits": [
{
"counter": "wa_check_number_exists_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 WA MCP server exposes 6 destructive tools including wa_clear_chat, wa_delete_chat, wa_delete_instance. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.
The WA MCP server has 43 write tools including wa_archive_chat, wa_block_contact, wa_create_group. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach WA MCP.
62 tools across 4 categories: Destructive, Execute, Read, Write. 7 are read-only. 55 can modify, create, or delete data.
Register the WA 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 62 WA MCP tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
