AI agents use add_connection to create or update resources in UOFastMCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your UOFastMCP environment.
This tool creates a new connection object and stores it in the connection cache, which is a reversible modification of the application's connection state. It does not execute commands, delete data, or move funds. While it could be misused to create connections to unauthorized databases if RBAC controls are weak, the tool itself is fundamentally a Write operation (create).
From the tool's definition Tool description states 'Add a new named connection to the connection cache for later use' — the verb 'Add' and action of persisting a new connection record to a cache constitutes creation of new data/state.
Attacks that exploit this kind of access
Add a new named connection to the connection cache for later use. It is categorised as a Write tool in the UOFastMCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the UOFast MCP server in PolicyLayer and add a rule for add_connection: 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 UOFastMCP. Nothing to install.
add_connection 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 add_connection 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 add_connection. 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.
add_connection is provided by the UOFast MCP server (rokipark/uofastmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
add_connection is one line of UOFast's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
