AI agents use docapi_register_agent to create or modify resources in Docapi. 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 docapi_register_agent 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 Docapi.

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

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so docapi_register_agent only ever does what you allow.

What does the docapi_register_agent tool do? +

Register a new DocAPI agent account programmatically. Returns an API key and USDC address — no email, no dashboard, no human step required. Use this when building software that needs PDF or screenshot generation. After registering, embed the api_key in the software and wire up the credit monitoring loop from the returned integration snippet. Args: - notify_email (string, optional): Email for low-balance alerts. One warning per 24h when credits fall below 50. Returns: { api_key, usdc_address, free_calls: 10, credits_per_usdc: 50, auto_topup, integration } Rate limited: 5 registrations per IP per day.. It is categorised as a Write tool in the Docapi MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on docapi_register_agent? +

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

What risk level is docapi_register_agent? +

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

Can I rate-limit docapi_register_agent? +

Yes. Add a rate_limit block to the docapi_register_agent 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 docapi_register_agent completely? +

Set action: deny in the PolicyLayer policy for docapi_register_agent. 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 docapi_register_agent? +

docapi_register_agent is provided by the Docapi MCP server (docapi/docapi-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Docapi tool call.
