getNetworks
Retrieve all supported blockchain networks to identify available options before using network-specific cryptocurrency data functions.
Instructions
REQUIRED FIRST STEP: Get all supported blockchain networks. Always call this first to see available networks before using any network-specific functions. Returns network IDs like "ethereum", "solana", etc.

Implementation Reference
- src/index.js:76-79 (handler)Handler function for the getNetworks tool. Fetches network data from the DexPaprika API endpoint '/networks' and formats it using formatMcpResponse.
async () => { const data = await fetchFromAPI('/networks'); return formatMcpResponse(data); } - src/index.js:75-75 (schema)Input schema for getNetworks tool: empty object indicating no input parameters are required.
{}, - src/index.js:72-80 (registration)Registration of the getNetworks tool using McpServer's tool() method, including name, description, schema, and handler function.

Returns network IDs like "ethereum", "solana", etc.', {}, async () => { const data = await fetchFromAPI('/networks'); return formatMcpResponse(data); } ); - src/index.js:37-46 (helper)Helper function that formats the raw API response data into the MCP protocol response format, used by getNetworks and other tools.
function formatMcpResponse(data) { return { content: [ { type: "text", text: JSON.stringify(data) } ] }; } - src/index.js:10-34 (helper)Helper function to perform HTTP fetches to the DexPaprika API base URL, with error handling for rate limits and other issues, called by getNetworks handler.
