What create_access_link does on Huly
AI agents use create_access_link to create or update resources in Huly, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Huly environment.
Why create_access_link is rated Medium
This tool creates new access credentials/links that grant others permission to join a workspace. While it modifies system state by introducing new access grants (Write), it does not move money (Financial), delete data (Destructive), or execute arbitrary code (Execute). The ability to set expiration and space restrictions provides some controls, but misconfiguration could grant unintended access.
From the tool's definition Tool 'creates' a workspace access link; description explicitly states 'Create a Huly workspace access link' and allows configuration of role, personalization, expiration, and space restrictions.
Attacks that exploit this kind of access
The rule that runs create_access_link safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Huly, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_access_link, this is the rule to start with:
create_access_link 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Huly, apply this rule, and every create_access_link call is checked against it from then on.
Questions about create_access_link
Create a Huly workspace access link. When role is omitted, role=${DEFAULT_ACCESS_LINK_ROLE}. Supports anonymous reusable guest links by setting personalized=false with notBefore and expiration, and can restrict access to specific Huly space IDs via spaces. It is categorised as a Write tool in the Huly MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Huly MCP server in PolicyLayer and add a rule for create_access_link: 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 Huly. Nothing to install.
create_access_link 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 create_access_link 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 create_access_link. 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.
create_access_link is provided by the Huly MCP server (@firfi/huly-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
