Implementation Reference
- src/tools/get_anon_key.ts:28-32 (handler)The async execute function implementing the get_anon_key tool logic. It retrieves the SelfhostedSupabaseClient from context and calls its getAnonKey() method to return the anon key.
execute: async (input: GetAnonKeyInput, context: ToolContext) => { const client = context.selfhostedClient; const key = client.getAnonKey(); // Use getter from client return { anon_key: key }; }, - src/tools/get_anon_key.ts:6-19 (schema)Zod schemas defining empty input, output with anon_key string field, and static MCP input schema (empty object).
const GetAnonKeyInputSchema = z.object({}); type GetAnonKeyInput = z.infer<typeof GetAnonKeyInputSchema>; // Output schema const GetAnonKeyOutputSchema = z.object({ anon_key: z.string(), }); // Static JSON Schema for MCP capabilities const mcpInputSchema = { type: 'object', properties: {}, required: [], }; - src/tools/get_anon_key.ts:22-33 (registration)Definition and export of the getAnonKeyTool object, which includes name, description, schemas, and execute handler. This is imported and registered elsewhere.
