Likes or removes a like from a page post or comment, acting as the Page. Args: - object_id (string): Post ID or Comment ID - page_id (string): Page ID (for token) - unlike (boolean): If true, removes the like instead
AI agents use meta_like_object to create or update resources in Meta MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Meta MCP Server environment.
This tool performs a reversible social action (liking or unliking content) on behalf of a Facebook Page. It modifies engagement state on a post or comment but does not delete content, execute code, or involve financial transactions. The action is reversible (the 'unlike' flag itself demonstrates reversibility).
From the tool's definition 'Likes or removes a like from a page post or comment, acting as the Page' — creates or removes a like interaction on social content
Documented attack patterns abuse exactly the kind of access meta_like_object gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Meta MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for meta_like_object:
{
"version": "1",
"default": "deny",
"tools": {
"meta_like_object": {
"limits": [
{
"counter": "meta_like_object_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}meta_like_object 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.

Likes or removes a like from a page post or comment, acting as the Page. Args: - object_id (string): Post ID or Comment ID - page_id (string): Page ID (for token) - unlike (boolean): If true, removes the like instead. It is categorised as a Write tool in the Meta MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Meta MCP Server MCP server in PolicyLayer and add a rule for meta_like_object: 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 Meta MCP Server. Nothing to install.
meta_like_object 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 meta_like_object 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 meta_like_object. 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.
meta_like_object is provided by the Meta MCP Server MCP server (oliverames/meta-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Meta MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
