MCP Tool Reference Low Risk

get_edge_function

Retrieves file contents for an Edge Function

Part of the Supabase MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

WHEN AI AGENTS USE THIS TOOL

AI agents call get_edge_function to retrieve information from Supabase without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions — but you may still want rate limits to control API costs.

WHY ENFORCE A POLICY ON GET_EDGE_FUNCTION

Even though get_edge_function only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

RECOMMENDED POLICY

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

supabase.yaml
tools:
  get_edge_function:
    rules:
      - action: allow

FREQUENTLY ASKED QUESTIONS

What does the get_edge_function tool do?

Retrieves file contents for an Edge Function. It is categorised as a Read tool in the Supabase MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on get_edge_function?

Add a rule in your Intercept YAML policy under the tools section for get_edge_function. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Supabase MCP server.

What risk level is get_edge_function?

get_edge_function is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit get_edge_function?

Yes. Add a rate_limit block to the get_edge_function rule in your Intercept 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.

How do I block get_edge_function completely?

Set action: deny in the Intercept policy for get_edge_function. 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.

What MCP server provides get_edge_function?

get_edge_function is provided by the Supabase MCP server (supabase-community/supabase-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
