Implementation Reference
- src/index.ts:31-53 (handler)The asynchronous handler function that implements the getSlot tool logic. It fetches the current Solana blockchain slot using the connection.getSlot() method and returns it in a structured MCP response format, with error handling.
async () => { try { const slot = await connection.getSlot(); return { content: [ { type: "text", text: `Current slot: ${slot}`, }, ], }; } catch (err) { const error = err as Error; return { content: [ { type: "text", text: `Failed to retrieve current slot: ${error.message}`, }, ], }; } } - src/index.ts:27-54 (registration)The server.tool() call that registers the 'getSlot' tool with the MCP server, specifying its name, description, schema (empty), and handler function.
server.tool( "getSlot", "Get the current slot", {}, async () => { try { const slot = await connection.getSlot(); return { content: [ { type: "text", text: `Current slot: ${slot}`, }, ], }; } catch (err) { const error = err as Error; return { content: [ { type: "text", text: `Failed to retrieve current slot: ${error.message}`, }, ], }; } } ); - src/index.ts:30-30 (schema)Empty input schema object, indicating the getSlot tool requires no parameters.
