Fetch a single campaign by ID with its full configuration.
AI agents call get_campaign to retrieve information from Claude Meta without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries campaign data without modifying, deleting, or executing any operations. It is a straightforward data lookup operation that returns existing campaign configuration information. The verb 'fetch' and lack of any modification language confirm Read classification.

Register the Claude Meta MCP server in PolicyLayer and add a rule for get_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 Claude Meta. Nothing to install.

Yes. Add a rate_limit block to the get_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.
