AI agents use follow_topic_live to create or update resources in GetNote MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your GetNote MCP Server environment.
This tool creates a subscription/association between a live stream and a knowledge base, which is a reversible write operation. It modifies the user's knowledge base by adding a new subscription entry. It does not execute code, delete data, or involve financial transactions.

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

Register the GetNote MCP Server MCP server in PolicyLayer and add a rule for follow_topic_live: 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 GetNote MCP Server. Nothing to install.
follow_topic_live 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 follow_topic_live 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 follow_topic_live. 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.
follow_topic_live is provided by the GetNote MCP Server MCP server (iswalle/getnote-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from GetNote MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
