Lists all organizations that the user is a member of.
AI agents call list_organizations to retrieve information from Supabase MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns organizational membership data without modifying, deleting, or executing any operations. It is a straightforward data retrieval action typical of Read category tools. The blast radius of misuse is minimal—an agent could learn what organizations exist but cannot alter them or access sensitive data beyond membership metadata.
From the tool's definition Tool name 'list_organizations' and description 'Lists all organizations that the user is a member of' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
Lists all organizations that the user is a member of. It is categorised as a Read tool in the Supabase MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Supabase MCP Server MCP server in PolicyLayer and add a rule for list_organizations: 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 Supabase MCP Server. Nothing to install.
list_organizations 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_organizations 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_organizations. 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_organizations is provided by the Supabase MCP Server MCP server (pipethedev/supabase-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
