AI agents use create_library_group to create or update resources in Pinako AI Bridge — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Pinako AI Bridge environment.
This tool creates new organizational metadata (a library group) in a reversible manner. It modifies the state of the Pinako extension by adding a new grouping structure, but the operation is not destructive—groups can be deleted or modified. There is no code execution, data deletion, financial impact, or external system manipulation.
From the tool's definition Tool description explicitly states 'Creates a new library group' and 'each call creates a new group', indicating creation of new organizational data. Returns createdGroupId confirming successful object instantiation.
Attacks that exploit this kind of access
Creates a new library group (an organizational umbrella over multiple libraries). Returns createdGroupId. After creating, use add_library_to_group to add member libraries. NOT IDEMPOTENT: each call creates a new group. On transient failures, DO NOT auto-retry — call list_libraries to inspect existing groups before retrying. It is categorised as a Write tool in the Pinako AI Bridge MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Pinako AI Bridge MCP server in PolicyLayer and add a rule for create_library_group: 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 Pinako AI Bridge. Nothing to install.
create_library_group 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_library_group 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_library_group. 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_library_group is provided by the Pinako AI Bridge MCP server (teleomorph/pinako-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
create_library_group is one line of Pinako AI Bridge's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
