Content Moderation

Moderate user-generated content using Vettly's AI-powered content moderation API. This skill uses the @vettly/mcp MCP server to check text, images, and video against configurable moderation policies with auditable decisions.

Setup

Add the @vettly/mcp MCP server to your configuration:

{
  "mcpServers": {
    "vettly": {
      "command": "npx",
      "args": ["-y", "@vettly/mcp"],
      "env": {
        "VETTLY_API_KEY": "your-api-key"
      }
    }
  }
}

Get an API key at vettly.dev.

Available Tools

moderate_content

Check text, image, or video content against a Vettly moderation policy. Returns a safety assessment with category scores, the action taken, provider used, latency, and cost.

Parameters:

• content (required) - The content to moderate (text string, or URL for images/video)
• policyId (required) - The policy ID to use for moderation
• contentType (optional, default: text) - Type of content: text, image, or video

validate_policy

Validate a Vettly policy YAML without saving it. Returns validation results with any syntax or configuration errors. Use this to test policy changes before deploying them.

Parameters:

• yamlContent (required) - The YAML policy content to validate

list_policies

List all moderation policies available in your Vettly account. Takes no parameters. Use this to discover available policy IDs before moderating content.

get_usage_stats

Get usage statistics for your Vettly account including request counts, costs, and moderation outcomes.

Parameters:

• days (optional, default: 30) - Number of days to include in statistics (1-365)

get_recent_decisions

Get recent moderation decisions with optional filtering by outcome, content type, or policy.

Parameters:

• limit (optional, default: 10) - Number of decisions to return (1-50)
• flagged (optional) - Filter to only flagged content (true) or safe content (false)
• policyId (optional) - Filter by specific policy ID
• contentType (optional) - Filter by content type: text, image, or video

When to Use

• Moderate user-generated content (comments, posts, uploads) before publishing
• Test and validate moderation policy YAML configs during development
• Audit recent moderation decisions to review flagged content
• Monitor moderation costs and usage across your account
• Compare moderation results across different policies

Examples

Moderate a user comment

Moderate this user comment for my community forum policy:
"I hate this product, it's the worst thing I've ever used and the developers should be ashamed"

Call list_policies to find available policies, then moderate_content with the appropriate policy ID and return the safety assessment.

Validate a policy before deploying

Validate this moderation policy YAML:

categories:
  - name: toxicity
    threshold: 0.8
    action: flag
  - name: spam
    threshold: 0.6
    action: block

Call validate_policy and report any syntax or configuration errors.

Review recent flagged content

Show me all flagged content from the last week

Call get_recent_decisions with flagged: true to retrieve recent moderation decisions that were flagged.

Tips

• Always call list_policies first if you don't know which policy ID to use
• Use validate_policy to test policy changes before deploying to production
• Use get_usage_stats to monitor costs and catch unexpected spikes
• Filter get_recent_decisions by contentType or policyId to narrow results
• For image and video moderation, pass the content URL rather than raw data
