Pin a critical fact with elevated importance (9.0). Use when the user
AI agents use widemem_pin to create or update resources in Widemem Ai — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Widemem Ai environment.
This tool modifies metadata (importance scoring) on existing facts in the memory layer without deleting data or executing external operations. It is a Write operation because it persistently changes the importance attribute of records, which is reversible (could be unpinned or rescored).
From the tool's definition Tool name 'widemem_pin' and description 'Pin a critical fact with elevated importance' indicate modification of stored data.
Documented attack patterns abuse exactly the kind of access widemem_pin gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Widemem Ai, and nothing reaches the server without passing your rules. This is the rule we recommend for widemem_pin:
{
"version": "1",
"default": "deny",
"tools": {
"widemem_pin": {
"limits": [
{
"counter": "widemem_pin_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}widemem_pin 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.

Pin a critical fact with elevated importance (9.0). Use when the user. It is categorised as a Write tool in the Widemem Ai MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Widemem Ai MCP server in PolicyLayer and add a rule for widemem_pin: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Widemem Ai. Nothing to install.
widemem_pin is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the widemem_pin rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for widemem_pin. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
widemem_pin is provided by the Widemem Ai MCP server (remete618/widemem-ai). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
