1 of Private Journal's 5 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 Private Journal, and nothing reaches the server without passing your rules. These are the rules we recommend:
{
"process_thoughts": {
"limits": [
{
"counter": "process_thoughts_per_hour",
"window": "hour",
"max": 30,
"scope": "grant"
}
]
}
} Prevents bulk unintended modifications from agents caught in loops.
{
"list_recent_entries": {
"limits": [
{
"counter": "list_recent_entries_per_minute",
"window": "minute",
"max": 60,
"scope": "grant"
}
]
}
} Controls API costs and prevents retry loops from exhausting upstream rate limits.
Free to start. No card required.
The Private Journal server has 1 write tools including process_thoughts. 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 Private Journal.
5 tools across 2 categories: Read, Write. 4 are read-only. 1 can modify, create, or delete data.
Register the Private Journal 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 5 Private Journal tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
