Input Schema (JSON Schema)

Implementation Reference

• src/index.ts:454-570 (handler)

  Dynamic handler that implements the logic for 'post_deleted_profiles_restore' and all other tools by matching the tool name to OpenAPI paths and making the corresponding HTTP request to the GoLogin API.
  private async callDynamicTool( toolName: string, parameters: CallParameters = {}, headers: Record<string, string> = {} ): Promise<CallToolResult> { console.log('parameters', parameters.body); if (!this.apiSpec || !this.apiSpec.paths) { throw new Error('API specification not loaded'); } let targetPath = ''; let targetMethod = ''; let operation: OpenAPIV3.OperationObject | undefined; for (const [path, pathItem] of Object.entries(this.apiSpec.paths)) { if (!pathItem) continue; for (const [method, op] of Object.entries(pathItem)) { if (['get', 'post', 'put', 'delete', 'patch', 'head', 'options'].includes(method) && op) { const opObj = op as OpenAPIV3.OperationObject; const generatedToolName = `${method}${path.replace('browser', 'profile').replace(/[^a-zA-Z0-9]/g, '_')}`; if (generatedToolName === toolName) { targetPath = path; targetMethod = method.toUpperCase(); operation = opObj; break; } } } if (operation) break; } if (!operation) { throw new Error(`Tool "${toolName}" not found`); } let url = `${this.baseUrl}${targetPath}`; const requestHeaders: Record<string, string> = { ...headers }; let requestBody: string | undefined; requestHeaders['User-Agent'] = 'gologin-mcp'; console.error('this.token', this.token); if (this.token) { requestHeaders['Authorization'] = `Bearer ${this.token}`; } if (parameters.path) { for (const [key, value] of Object.entries(parameters.path)) { url = url.replace(`{${key}}`, encodeURIComponent(value)); } } const queryParams = new URLSearchParams(); if (parameters.query) { for (const [key, value] of Object.entries(parameters.query)) { if (value) { queryParams.append(key, value); } } } if (queryParams.toString()) { url += `?${queryParams.toString()}`; } if (parameters.body && ['POST', 'PUT', 'PATCH', 'DELETE'].includes(targetMethod)) { requestHeaders['Content-Type'] = 'application/json'; requestBody = JSON.stringify(parameters.body); } console.log('requestBody', requestBody); try { const fetchOptions: RequestInit = { method: targetMethod, headers: requestHeaders, }; console.error('fetchOptions', fetchOptions); if (requestBody) { fetchOptions.body = requestBody; } const response = await fetch(url, fetchOptions); const responseHeaders: Record<string, string> = {}; response.headers.forEach((value, key) => { responseHeaders[key] = value; }); let responseBody: any; const contentType = response.headers.get('content-type') || ''; if (contentType.includes('application/json')) { try { responseBody = await response.json(); } catch { responseBody = await response.text(); } } else { responseBody = await response.text(); } return { content: [ { type: 'text', text: `API Call Result:\n` + `URL: ${url}\n` + `Method: ${targetMethod}\n` + `Status: ${response.status} ${response.statusText}\n\n` + `Response Headers:\n${JSON.stringify(responseHeaders, null, 2)}\n\n` + `Response Body:\n${typeof responseBody === 'object' ? JSON.stringify(responseBody, null, 2) : responseBody}`, }, ], }; } catch (error) { throw new Error(`API call failed: ${error instanceof Error ? error.message : String(error)}`); } }
• src/index.ts:47-71 (registration)

  Dynamic registration of tools via ListTools handler; generates and exposes 'post_deleted_profiles_restore' based on OpenAPI specification.
  this.server.setRequestHandler(ListToolsRequestSchema, async () => { const tools: Tool[] = []; if (this.apiSpec && this.apiSpec.paths) { for (const [path, pathItem] of Object.entries(this.apiSpec.paths)) { if (!pathItem) continue; for (const [method, operation] of Object.entries(pathItem)) { if (['get', 'post', 'put', 'delete', 'patch', 'head', 'options'].includes(method) && operation) { const op = operation as OpenAPIV3.OperationObject; const toolName = `${method}${path.replace('browser', 'profile').replace(/[^a-zA-Z0-9]/g, '_')}`; const inputSchema = this.buildInputSchema(op, path); tools.push({ name: toolName, description: op.summary || op.description || `${method.toUpperCase()} ${path}`, inputSchema, }); } } } } return { tools }; });
• src/index.ts:204-249 (schema)

  Dynamically builds the input schema for 'post_deleted_profiles_restore' from the matching OpenAPI operation.
  private buildInputSchema(operation: OpenAPIV3.OperationObject, path: string): any { const properties: any = {}; const required: string[] = []; const pathParams = this.extractPathParameters(operation, path); const queryParams = this.extractQueryParameters(operation); const bodySchema = this.extractRequestBodySchema(operation); if (pathParams.properties && Object.keys(pathParams.properties).length > 0) { for (const [key, prop] of Object.entries(pathParams.properties)) { properties[key] = this.convertOpenAPISchemaToJsonSchema(prop as OpenAPIV3.SchemaObject | OpenAPIV3.ReferenceObject); if (pathParams.required.includes(key)) { required.push(key); } } } if (queryParams.properties && Object.keys(queryParams.properties).length > 0) { for (const [key, prop] of Object.entries(queryParams.properties)) { properties[key] = this.convertOpenAPISchemaToJsonSchema(prop as OpenAPIV3.SchemaObject | OpenAPIV3.ReferenceObject); if (queryParams.required.includes(key)) { required.push(key); } } } if (bodySchema && bodySchema.properties) { for (const [key, prop] of Object.entries(bodySchema.properties)) { properties[key] = this.convertOpenAPISchemaToJsonSchema(prop as OpenAPIV3.SchemaObject | OpenAPIV3.ReferenceObject); if (bodySchema.required && bodySchema.required.includes(key)) { required.push(key); } } } const schema: any = { type: 'object', properties, }; if (required.length > 0) { schema.required = required; } return schema; }
• src/index.ts:73-93 (handler)

  Entry point handler for calling any tool, including 'post_deleted_profiles_restore', dispatching to dynamic tool execution.
  this.server.setRequestHandler(CallToolRequestSchema, async (request: any): Promise<CallToolResult> => { const { name, arguments: args } = request.params; if (!args) { throw new Error('No arguments provided'); } console.log('args', args); try { const parameters: CallParameters = this.extractParametersFromArgs(name, args); return await this.callDynamicTool(name, parameters, args.headers as Record<string, string> | undefined); } catch (error) { return { content: [ { type: 'text', text: `Error: ${error instanceof Error ? error.message : String(error)}`, }, ], }; } });
• src/index.ts:96-175 (helper)

  Helper to parse tool arguments into HTTP path/query/body parameters by matching toolName to API operation.
  private extractParametersFromArgs(toolName: string, args: Record<string, any>): CallParameters { if (!this.apiSpec || !this.apiSpec.paths) { return { body: args }; } let operation: OpenAPIV3.OperationObject | undefined; let path = ''; for (const [apiPath, pathItem] of Object.entries(this.apiSpec.paths)) { if (!pathItem) continue; for (const [method, op] of Object.entries(pathItem)) { if (['get', 'post', 'put', 'delete', 'patch', 'head', 'options'].includes(method) && op) { const opObj = op as OpenAPIV3.OperationObject; const generatedToolName = opObj.operationId || `${method}_${apiPath.replace(/[^a-zA-Z0-9]/g, '_')}`; if (generatedToolName === toolName) { operation = opObj; path = apiPath; break; } } } if (operation) break; } if (!operation) { return { body: args }; } const pathParams: Record<string, string> = {}; const queryParams: Record<string, string> = {}; const bodyParams: any = {}; const pathParamNames = path.match(/\{([^}]+)\}/g)?.map(p => p.slice(1, -1)) || []; if (operation.parameters) { operation.parameters.forEach(param => { if ('$ref' in param) return; const parameter = param as OpenAPIV3.ParameterObject; const paramName = parameter.name; if (parameter.in === 'path' && args[paramName] !== undefined) { pathParams[paramName] = String(args[paramName]); } else if (parameter.in === 'query' && args[paramName] !== undefined) { queryParams[paramName] = String(args[paramName]); } }); } pathParamNames.forEach(paramName => { if (args[paramName] !== undefined && !pathParams[paramName]) { pathParams[paramName] = String(args[paramName]); } }); const usedParams = new Set([...Object.keys(pathParams), ...Object.keys(queryParams)]); for (const [key, value] of Object.entries(args)) { if (!usedParams.has(key)) { bodyParams[key] = value; } } const parameters: CallParameters = {}; if (Object.keys(pathParams).length > 0) { parameters.path = pathParams; } if (Object.keys(queryParams).length > 0) { parameters.query = queryParams; } if (Object.keys(bodyParams).length > 0) { parameters.body = bodyParams; } return parameters; }
