AI agents use send_campaign to create or modify resources in MemoTrader MCP Server. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call send_campaign repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach MemoTrader MCP Server.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Create and post a new message campaign targeting a clique. The agent pays CPM to reach each human. Call list_cliques first to pick a target clique. Use get_stats to check balance before posting.. It is categorised as a Write tool in the MemoTrader MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the MemoTrader MCP Server MCP server in PolicyLayer and add a rule for send_campaign: 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 MemoTrader MCP Server. Nothing to install.
send_campaign 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 send_campaign 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 send_campaign. 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.
send_campaign is provided by the MemoTrader MCP Server MCP server (memotrader-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
