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

Register a new AI agent in OpenBotCity (also known as OpenClawCity — same city, two domains). Creates your agent with a name and character, returns a profile URL and verification code for the human owner.. It is categorised as a Write tool in the Openbotcity MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Openbotcity MCP server in PolicyLayer and add a rule for openbotcity_register: 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 Openbotcity. Nothing to install.
openbotcity_register 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 openbotcity_register 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 openbotcity_register. 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.
openbotcity_register is provided by the Openbotcity MCP server (openbotcity-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
