AI agents call guide to retrieve information from Zion without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

projectExId | string | — |
Parameters from the server's own tool schema.
The tool only reads and returns guidance/documentation about backend capabilities. It does not create, modify, delete, or execute anything. It is a reference lookup tool to be called before editing, indicating it is a read-only operation.
From the tool's definition 'Load the domain guide' and 'Returns guidance for the loaded project's type-system state' — purely retrieves documentation/rules/conventions with no side effects
Attacks that exploit this kind of access
Load the domain guide for a backend capability — the rules, conventions, and gotchas for a plugin area (database, type, bindings, actionflow, api, tpa, zai, component, permissions, payments, logs, agent). Returns guidance for the loaded project’s type-system state. Call before editing an unfamiliar area, or when a meta-tool call is rejected. It is categorised as a Read tool in the Zion MCP Server, which means it retrieves data without modifying state.
guide accepts 2 parameters: plugin, projectExId. Required: plugin. The full parameter table on this page comes from the server's own tool schema.
Register the Zion MCP server in PolicyLayer and add a rule for guide: 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 Zion. Nothing to install.
guide is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the guide 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 guide. 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.
guide is provided by the Zion MCP server (zion-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
guide is one line of Zion's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
