Lists all Pinako libraries. Default: returns id, title, description, tabCount, and note metadata (id+title only, NO note content). Pass include_tabs:true to ALSO embed every library\
AI agents call list_libraries to retrieve information from Pinako AI Bridge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries library metadata without creating, modifying, deleting, or executing any operations. It is a pure read operation with no side effects. The optional include_tabs parameter only expands the data returned, still remaining read-only.
From the tool's definition Tool description states it 'Lists all Pinako libraries' and returns metadata (id, title, description, tabCount, note id+title). The verb 'list' and read-only nature of returning data without modification confirms retrieval-only behavior.

Lists all Pinako libraries. Default: returns id, title, description, tabCount, and note metadata (id+title only, NO note content). Pass include_tabs:true to ALSO embed every library\. It is categorised as a Read tool in the Pinako AI Bridge MCP Server, which means it retrieves data without modifying state.
Register the Pinako AI Bridge MCP server in PolicyLayer and add a rule for list_libraries: 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.
list_libraries is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_libraries 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 list_libraries. 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.
list_libraries 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.
list_libraries 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.
