Why metrics needs a policy

This tool only queries and returns publicly available social media metrics from post URLs. It performs no modifications, deletions, code execution, or financial operations.

Questions about metrics

What does the metrics tool do? +

Get a public social post's metrics. Give a post URL (YouTube, X/Twitter incl. view counts, TikTok incl. photo posts, Bluesky, Mastodon (major instances), Hacker News (points + comments), Stack Overflow (views + score + answers), Instagram, Threads, LinkedIn — short links like vm.tiktok.com and t.co resolve automatically) and get normalized { platform, views, likes, comments, shares, quotes, bookmarks, publishedAt, title, author, thumbnail } — shares = reshares (X retweets, TikTok shares, Bluesky reposts); quotes = quote posts (X, Bluesky); bookmarks = saves (X). Free. It is categorised as a Read tool in the Pulse MCP Server, which means it retrieves data without modifying state.

What parameters does metrics accept? +

metrics accepts 1 parameter: url. Required: url. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on metrics? +

Register the Pulse MCP server in PolicyLayer and add a rule for metrics: 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 Pulse. Nothing to install.

What risk level is metrics? +

metrics is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit metrics? +

Yes. Add a rate_limit block to the metrics 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.

How do I block metrics completely? +

Set action: deny in the PolicyLayer policy for metrics. 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.

What MCP server provides metrics? +

metrics is provided by the Pulse MCP server (pulse-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
