Implementation Reference
- src/index.ts:529-558 (handler)The main handler function for the 'search_markets' tool. It validates input parameters using SearchMarketsSchema, constructs a URLSearchParams query string, fetches market data from the Manifold Markets API endpoint '/v0/search-markets', handles errors, and returns the JSON-stringified results as text content.
case 'search_markets': { const params = SearchMarketsSchema.parse(args); const searchParams = new URLSearchParams(); if (params.term) searchParams.set('term', params.term); if (params.limit) searchParams.set('limit', params.limit.toString()); if (params.filter) searchParams.set('filter', params.filter); if (params.sort) searchParams.set('sort', params.sort); const response = await fetch( `${API_BASE}/v0/search-markets?${searchParams}`, { headers: { Accept: 'application/json' } } ); if (!response.ok) { throw new McpError( ErrorCode.InternalError, `Manifold API error: ${response.statusText}` ); } const markets = await response.json(); return { content: [ { type: 'text', text: JSON.stringify(markets, null, 2), }, ], }; } - src/index.ts:51-56 (schema)Zod schema defining the input parameters for the 'search_markets' tool: optional search term, limit (1-100), filter (all/open/closed/resolved), and sort (newest/score/liquidity). Used for validation in the handler.
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:214-226 (registration)Tool registration entry in the listTools response. Defines the tool name, description, and JSON Schema for inputs, making it discoverable by MCP clients.
