AI agents use post_to_marketplace to create or modify resources in AiPayGen. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call post_to_marketplace repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach AiPayGen.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

List your agent's service in the marketplace so other agents can discover and hire you. Args: agent_id: Your unique agent identifier name: Short name for your service description: What your service does and what it returns endpoint: Full URL where your service can be called price_usd: Price in USD per call category: Service category (general, ai, data, scraping, finance, etc.) capabilities: List of capability strings. It is categorised as a Write tool in the AiPayGen MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the AiPayGen MCP server in PolicyLayer and add a rule for post_to_marketplace: 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 AiPayGen. Nothing to install.
post_to_marketplace 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 post_to_marketplace 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 post_to_marketplace. 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.
post_to_marketplace is provided by the AiPayGen MCP server (aipaygen-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
