Implementation Reference
- src/index.js:91-94 (handler)Handler function that fetches DEXes data from DexPaprika API for the specified network with optional pagination and formats the response for MCP.
async ({ network, page, limit }) => { const data = await fetchFromAPI(`/networks/${network}/dexes?page=${page}&limit=${limit}`); return formatMcpResponse(data); } - src/index.js:86-90 (schema)Zod schema defining input parameters: network (required string), page and limit (optional numbers with defaults).
{ network: z.string().describe('Network ID from getNetworks (e.g., "ethereum", "solana")'), page: z.number().optional().default(0).describe('Page number for pagination'), limit: z.number().optional().default(10).describe('Number of items per page') }, - src/index.js:83-95 (registration)Complete registration of the getNetworkDexes tool using McpServer.tool method, including name, description, input schema, and handler function.
