Implementation Reference
- src/index.ts:26-79 (handler)The handler function that implements the logic for the 'list-all-tools' tool. It fetches connected servers, lists tools from each via serverManager.listTools, handles errors per server, and returns a JSON-formatted response with all tools grouped by server name.async (args, extra) => { try { const servers = serverManager.getConnectedServers(); if (servers.length === 0) { return { content: [ { type: "text", text: "No connected servers.", }, ], }; } const allTools: Record<string, any> = {}; // Get tools list from each server for (const serverName of servers) { try { const toolsResponse = await serverManager.listTools(serverName); allTools[serverName] = toolsResponse; } catch (error) { allTools[serverName] = { error: `Failed to get tools list: ${ (error as Error).message }`, }; } } return { content: [ { type: "text", text: JSON.stringify(allTools, null, 2), }, ], }; } catch (error) { return { content: [ { type: "text", text: `Failed to get tools list from all servers: ${ (error as Error).message }`, }, ], isError: true, }; } }
- src/index.ts:21-80 (registration)Registration of the 'list-all-tools' tool using server.tool(), including description, empty input schema, and inline handler function.// Tool to return tools list from all servers server.tool( "list-all-tools", "List all available tools from all connected servers. Before starting any task based on the user's request, always begin by using this tool to get a list of any additional tools that may be available for use.", {}, // Use empty object when there are no parameters async (args, extra) => { try { const servers = serverManager.getConnectedServers(); if (servers.length === 0) { return { content: [ { type: "text", text: "No connected servers.", }, ], }; } const allTools: Record<string, any> = {}; // Get tools list from each server for (const serverName of servers) { try { const toolsResponse = await serverManager.listTools(serverName); allTools[serverName] = toolsResponse; } catch (error) { allTools[serverName] = { error: `Failed to get tools list: ${ (error as Error).message }`, }; } } return { content: [ { type: "text", text: JSON.stringify(allTools, null, 2), }, ], }; } catch (error) { return { content: [ { type: "text", text: `Failed to get tools list from all servers: ${ (error as Error).message }`, }, ], isError: true, }; } } );
- src/server-manager.ts:197-200 (helper)McpServerManager.listTools helper method, which delegates to the connected client's listTools to fetch tools from a specific server. Used in the list-all-tools handler.async listTools(serverName: string): Promise<any> { const client = this.getClient(serverName); return await client.listTools(); }
- src/server-manager.ts:220-222 (helper)McpServerManager.getConnectedServers helper method, which returns the list of currently connected server names. Used in the list-all-tools handler.getConnectedServers(): string[] { return Array.from(this.clients.keys()); }
