WHAT IT DOES

What gateway_register does on Rokha

AI agents use gateway_register to create or update resources in Rokha, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Rokha environment.

Parameter	Type	Required	Description
`name`	string	Yes	Short name — kebab-cased into the tool namespace.
`server_url`	string	Yes	The upstream MCP server URL.
`secret_alias`	string	—	Vault alias that authenticates it (omit for open servers).

Parameters from the server's own tool schema.

RECOMMENDED RULE

The rule that runs gateway_register safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Rokha, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For gateway_register, this is the rule to start with:

gateway_register Rate-limited

gateway_register stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about gateway_register

What does the gateway_register tool do? +

Register an external MCP server behind your Rokha GATEWAY — one endpoint that aggregates all your servers with credentials injected server-side. Any MCP client pointed at the gateway URL (with your Rokha token) then sees this server's tools namespaced <slug>_<tool>. secret_alias names a vault key/OAuth grant that authenticates it (omit for open servers). Requires a logged-in identity. Cap 20. It is categorised as a Write tool in the Rokha MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does gateway_register accept? +

gateway_register accepts 3 parameters: name, server_url, secret_alias. Required: name, server_url. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on gateway_register? +

Register the Rokha MCP server in PolicyLayer and add a rule for gateway_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 Rokha. Nothing to install.

What risk level is gateway_register? +

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

Can I rate-limit gateway_register? +

Yes. Add a rate_limit block to the gateway_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.

How do I block gateway_register completely? +

Set action: deny in the PolicyLayer policy for gateway_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.

What MCP server provides gateway_register? +

gateway_register is provided by the Rokha MCP server (https://rokha.ai/mcp/jsonrpc). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
