Implementation Reference
- src/index.ts:363-425 (handler)The handler function that validates input parameters, prepares the update payload using UpdateLinkParams type, makes a PATCH request to /links/{linkId} on the dub.co API, and returns success or error response.private async updateLink(args: any): Promise<any> { if (!args.linkId) { throw new McpError( ErrorCode.InvalidParams, 'Link ID is required' ); } // Prepare update parameters const updateParams: UpdateLinkParams = {}; if (args.url) { updateParams.url = args.url; } if (args.domain) { updateParams.domain = args.domain; } if (args.key) { updateParams.key = args.key; } if (Object.keys(updateParams).length === 0) { throw new McpError( ErrorCode.InvalidParams, 'At least one parameter to update is required' ); } try { const response = await this.axiosInstance.patch(`/links/${args.linkId}`, updateParams); const link = response.data; return { content: [ { type: 'text', text: `Link updated: ${link.shortLink}\n\nDestination: ${link.url}\nID: ${link.id}`, }, ], }; } catch (error) { if (axios.isAxiosError(error)) { const axiosError = error as AxiosError<ApiErrorResponse>; const statusCode = axiosError.response?.status; const errorData = axiosError.response?.data; const errorMessage = errorData?.error || errorData?.message || axiosError.message; return { content: [ { type: 'text', text: `Error updating link: ${statusCode} - ${errorMessage}`, }, ], isError: true, }; } throw error; } }
- src/index.ts:130-155 (registration)Registration of the 'update_link' tool in the ListToolsRequestSchema handler, including name, description, and input schema defining required linkId and optional update fields.{ name: 'update_link', description: 'Update an existing short link on dub.co', inputSchema: { type: 'object', properties: { linkId: { type: 'string', description: 'The ID of the link to update', }, url: { type: 'string', description: 'The new destination URL', }, domain: { type: 'string', description: 'The new domain for the short link', }, key: { type: 'string', description: 'The new slug for the short link', }, }, required: ['linkId'], }, },
- src/index.ts:53-59 (schema)TypeScript interface defining the parameters for updating a link, used to type the payload sent to the dub.co API.interface UpdateLinkParams { url?: string; domain?: string; key?: string; externalId?: string; // ... other optional parameters }
- src/index.ts:204-205 (handler)Dispatch case in the CallToolRequestSchema handler that routes 'update_link' calls to the updateLink method.case 'update_link': return await this.updateLink(request.params.arguments);
