Log interaction with Windsurf Cascade AI
AI agents use cascade_interaction to create or update resources in SAM — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your SAM environment.
The tool logs/records interaction data, which is a write operation (creating a new log entry). It does not execute code, delete data, or involve financial transactions. Severity is low as it only records interaction metadata. Confidence is moderate because the description is brief and doesn't fully clarify what 'log interaction' entails or whether it has additional side effects.

Documented attack patterns abuse exactly the kind of access cascade_interaction gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SAM, and nothing reaches the server without passing your rules. This is the rule we recommend for cascade_interaction:
{
"version": "1",
"default": "deny",
"tools": {
"cascade_interaction": {
"limits": [
{
"counter": "cascade_interaction_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}cascade_interaction 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.

Log interaction with Windsurf Cascade AI. It is categorised as a Write tool in the SAM MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the SAM MCP server in PolicyLayer and add a rule for cascade_interaction: 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 SAM. Nothing to install.
cascade_interaction 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 cascade_interaction 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 cascade_interaction. 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.
cascade_interaction is provided by the SAM MCP server (pigrieco/mcp-memory-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from SAM, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
