WHAT IT DOES

What set_agent_uri does on Basis MCP Server

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

RISK

Why set_agent_uri is rated Medium

This tool modifies agent configuration (the URI endpoint), which is a reversible write operation. It does not execute arbitrary code, delete data irreversibly, or move funds. The severity is medium because a malicious agent URI could redirect subsequent operations to an attacker-controlled endpoint, creating downstream risks, though the tool itself only performs configuration update.

From the tool's definition Tool name 'set_agent_uri' and description 'Update your agent' indicate modification of agent configuration data. The verb 'Update' and the nature of setting a URI confirm data mutation.

RECOMMENDED RULE

The rule that runs set_agent_uri safely

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

set_agent_uri Rate-limited

set_agent_uri 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.
