dual_request_access · DUAL MCP Server MCP: Risk & Policy

WHAT IT DOES

What dual_request_access does on DUAL MCP Server

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

WHY IT NEEDS A POLICY

Why dual_request_access needs a policy

Requesting access submits a request/application to a platform, which creates a new record or state change (a pending access request). This is a Write operation as it creates data reversibly. It does not execute code, delete data, or move money. Severity is medium because a misused access request could grant unauthorized permissions to gated features on a blockchain/Web3 platform.

From the tool's definition Request access to a gated platform feature.

dual_request_access Rate-limited

dual_request_access 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.
