Register your email to unlock 500 queries/day (up from 50). Returns an API key to add to your MCP server config.
AI agents use register to create or update resources in ASTGL Knowledge — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ASTGL Knowledge environment.
| Parameter | Type | Required | Description |
|---|---|---|---|
email | string | Yes | Your email address for registration |
Parameters from the server's own tool schema.
The tool creates a new registration record (email account binding) and generates/returns an API key, which modifies the state of the user's account. This is a reversible write operation. While it involves credential generation, it doesn't execute arbitrary code, delete data, or move money.
From the tool's definition Tool description states it 'Register your email to unlock 500 queries/day' and 'Returns an API key to add to your MCP server config' — actions that create/modify account state and credentials in a system.
Documented attack patterns abuse exactly the kind of access register gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ASTGL Knowledge, and nothing reaches the server without passing your rules. This is the rule we recommend for register:
{
"version": "1",
"default": "deny",
"tools": {
"register": {
"limits": [
{
"counter": "register_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}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.

Register your email to unlock 500 queries/day (up from 50). Returns an API key to add to your MCP server config. It is categorised as a Write tool in the ASTGL Knowledge MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
register accepts 1 parameter: email. Required: email. The full parameter table on this page comes from the server's own tool schema.
Register the ASTGL Knowledge MCP server in PolicyLayer and add a rule for 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 ASTGL Knowledge. Nothing to install.
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 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 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.
register is provided by the ASTGL Knowledge MCP server (mcp-astgl-knowledge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from ASTGL Knowledge, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
