Create a new campaign on PostEverywhere for grouping related posts. Returns the campaign id, which can then be passed as campaign_id when creating posts via create_post.
AI agents use create_campaign to create or update resources in Posteverywhere — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Posteverywhere environment.
This tool creates new data structures (campaigns) that organize social media posts. While campaign creation is reversible (campaigns can be deleted via delete_campaign), it modifies state and enables downstream actions like creating posts across multiple social platforms.
From the tool's definition Tool description states "Create a new campaign on PostEverywhere for grouping related posts" and explicitly uses the verb "Create", which is a reversible data modification operation. The tool returns a campaign_id for subsequent use.
Attacks that exploit this kind of access
Create a new campaign on PostEverywhere for grouping related posts. Returns the campaign id, which can then be passed as campaign_id when creating posts via create_post. It is categorised as a Write tool in the Posteverywhere MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Posteverywhere MCP server in PolicyLayer and add a rule for create_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 Posteverywhere. Nothing to install.
create_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 create_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 create_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.
create_campaign is provided by the Posteverywhere MCP server (posteverywhere/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
