Generates TypeScript types based on the database schema. LLMs can save this to a file and use it in their code.
AI agents call generate_typescript_types 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.
The tool reads the database schema and generates TypeScript type definitions. It is purely a read/introspection operation with no side effects. The mention of saving to a file is a suggestion for LLM usage, not an action the tool itself performs on any system.
From the tool's definition 'Generates TypeScript types based on the database schema' — this introspects the schema to produce type definitions; no data is modified
Attacks that exploit this kind of access
Generates TypeScript types based on the database schema. LLMs can save this to a file and use it in their code. 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 generate_typescript_types: 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.
generate_typescript_types 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 generate_typescript_types 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 generate_typescript_types. 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.
generate_typescript_types 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.
generate_typescript_types is one line of Supabase MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
