Implementation Reference
- src/index.ts:51-56 (schema)Zod schema for search_markets input validation, with optional fields: term, limit (1-100), filter (all/open/closed/resolved), sort (newest/score/liquidity).
const SearchMarketsSchema = z.object({ term: z.string().optional(), limit: z.number().min(1).max(100).optional(), filter: z.enum(['all', 'open', 'closed', 'resolved']).optional(), sort: z.enum(['newest', 'score', 'liquidity']).optional(), }); - src/index.ts:214-225 (registration)Registration of the 'search_markets' tool in the ListToolsRequestSchema handler, defining its name, description, and input schema (term, limit, filter, sort).
