AI agents call get_publishing_post to retrieve information from Sprout without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves data about a specific publishing post identified by ID. The verb 'Retrieve' and the passive nature of the operation (no modification, deletion, or execution) clearly place this in the Read category. The severity is low because the blast radius of misuse is minimal—an attacker could only read post data they may already have access to through the Sprout Social API.
From the tool's definition Tool name 'get_publishing_post' and description 'Retrieve a specific publishing post by ID' indicate a retrieval operation with no side effects.

Register the Sprout MCP server in PolicyLayer and add a rule for get_publishing_post: 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 Sprout. Nothing to install.
get_publishing_post is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_publishing_post 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 get_publishing_post. 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.
