// WHEN AI AGENTS USE THIS TOOL

AI agents use publish to create or modify resources in Pipepost. 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.

// WHY ENFORCE A POLICY ON PUBLISH

Without a policy, an AI agent could call publish repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Pipepost.

// RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the publish tool do? +

Publish a markdown article to one CMS platform: devto, ghost, hashnode, wordpress, medium, or substack. Costs 1 credit per call. Requires platform credentials configured via the 'setup' tool. Supports draft|published status, tags, canonical_url, series, and cover image. Substack is published via reverse-engineered cookie auth. Returns: { url, id, platform, status }. Common errors: platform not configured (VALIDATION_ERROR), credit exhaustion (PAYMENT_REQUIRED), upstream 4xx/5xx (PLATFORM_ERROR), network timeout (NETWORK_ERROR).. It is categorised as a Write tool in the Pipepost MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on publish? +

Add a rule in your Intercept YAML policy under the tools section for publish. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Pipepost MCP server.

What risk level is publish? +

publish is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit publish? +

Yes. Add a rate_limit block to the publish rule in your Intercept 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 publish completely? +

Set action: deny in the Intercept policy for publish. 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 publish? +

publish is provided by the Pipepost MCP server (pipepost-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
