AI agents use send_job_message to create or modify resources in Humanpages. 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 send_job_message 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 Humanpages.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Send a message to the human on an active job. Works on PENDING, ACCEPTED, PAID, STREAMING, and PAUSED jobs. The human receives email and Telegram notifications. Use get_job_messages to read replies. Rate limit: 10/minute. Max 2000 chars.. It is categorised as a Write tool in the Humanpages MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Humanpages MCP server in PolicyLayer and add a rule for send_job_message: 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 Humanpages. Nothing to install.
send_job_message 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 send_job_message 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 send_job_message. 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.
send_job_message is provided by the Humanpages MCP server (humanpages). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
